Description:
TECHNICAL FIELD OF THE INVENTION 
       [0001]    The invention relates to the field of polymer materials, and in particular to a polyphenylene sulfide resin composition, and a moulding and a manufacturing process for the moulding thereof. 
       BACKGROUND OF THE INVENTION 
       [0002]    Polyphenylene sulfide resin has the characteristics of excellent flowability, high-temperature resistance, corrosion resistance and flame retardancy, balanced physical mechanical performance, extremely high size stability, good electric performance and the like, and is widely used in the fields such as electrics, electronic parts or automobile parts. 
         [0003]    A polyphenylene sulfide molecular main chain consists of a large number of benzene ring repeating units. Compared with other engineering plastic, the polyphenylene sulfide resin is high in rigidity and low in toughness as polyphenylene sulfide is easily crystallized thermoplastic resin. 
         [0004]    In the Patent Document 1 (of which the publication patent number is CN 101553537 B), a glass fiber with a flat section is added into the polyphenylene sulfide resin, thus further improving its rigidity and flowability. However, the polyphenylene sulfide resin is easy to crystallize; generally, after an inorganic filler such as the glass fiber is added, the toughness of the composition of the polyphenylene sulfide resin is not satisfactory, and the deformation resistance performance of a polyphenylene sulfide resin product is low; when deformed under outer force, the product is easy to break. The Patent Document 2 (of which the publication patent number is CN 1314762 C) discloses a feature that a blend of hydrogenized Styrene Butadiene Styrene (SBS) or Ethylene-Propylene-Diene Monomer (EPDM-g-St) and ethylene-methacrylic acid glycidyl ester is added to improve the toughness of the glass fiber-enhanced polyphenylene sulfide resin; although the toughness of the polyphenylene sulfide resin composition is improved, its rigidity is lowered. The Patent Document 3 (of which the publication patent number is CN 101130633 A) discloses that PA6 is adopted to enhance the toughness of the glass fiber-enhanced polyphenylene sulfide resin; by the use of 10 percent of PA6, the toughness improving effect is the best, and the notched impact strength can be up to 13 kJ/m 2 , and however, its rigidity is lowered. 
         [0005]    In addition, on the one hand, wall thinning of a product is a tendency of development of the existing electronic industry, and a material is expected to be high in flowability. On the other hand, in view of the opinion of reducing the influence on the environment, the requirement on reduction of the halogen content of the material is higher and higher. The polyphenylene sulfide resin is obtained by performing polymerization reaction on p-dichlorobenzene and alkali metal sulfide or alkali metal sulfohydrate, so chlorine residues will be retained on the molecular end of a polymer thereof. The chlorine content of the polymer is generally decided by the molecular weight of the polymer, and the molecular weight is related to the viscosity of the polymer. That is, if the flowability is high and the viscosity is low, the molecular weight is low, the total number of molecular ends is large, and the chlorine content is high. In addition, a reduction of the molecular weight is unfavorable for the mechanical performance of the polymer. At present, the polyphenylene sulfide resin is generally combined with the inorganic filler, thus forming the resin composition; the chlorine content of the resin composition is reduced to an extent; however, in view that the resin composition must have the flowability and the mechanical strength, there are not too much inorganic fillers being added, so a low chlorine content level required in the market cannot be achieved only by adding finite inorganic fillers for combination. Therefore, the conventional art cannot provide a polyphenylene sulfide resin composition which is high in flowability, lower in chlorine content and high in both rigidity and toughness. 
         [0006]    As an example of a polyphenylene sulfide resin moulding, the Patent Document 1 (of which the publication patent number is CN 101553537 B) discloses a polyphenylene sulfide resin moulding for an optical element, and the thinnest part of the moulding is 0.3 to 1.4 mm in thickness. The Patent Document 4 (of which the publication patent number is CN 101679745 B) discloses a moulding prepared from the polyphenylene sulfide resin composition for a voltage resistance part. The Patent Document 5 (of which the publication patent number is ON 1644366 A) discloses an embedded type moulding obtained by embedding the polyphenylene sulfide resin composition into a metal or inorganic solid, which is used in the fields of automobile components, electrical, electronic and OA machine components and the like. However, the temperatures of moulds of the above mouldings are higher than 130° C. Under high mould temperature, high crystallization degree of the moulding is easily caused, and the toughness of the moulding is insufficient. 
       SUMMARY OF THE INVENTION 
       [0007]    The invention provides a polyphenylene sulfide resin composition, which is excellent in flowability, low in chlorine content and high in toughness and rigidity, in order to solve the problems in the conventional art. 
         [0008]    The goal of the invention can be achieved by the following measures: 
         [0009]    A polyphenylene sulfide resin composition, including: polyphenylene sulfide resin (A), and a deformed cross-section glass fiber (B), wherein the chlorine content of the polyphenylene sulfide resin composition is equal to or lower than 1,000 ppm. 
         [0010]    The lower limit of the chlorine content of the polyphenylene sulfide resin composition is not specifically defined, which can be equal to or higher than 10 ppm, preferably equal to or higher than 100 ppm, more preferably equal to or higher than 300 ppm. 
         [0011]    The polyphenylene sulfide resin belongs to thermoplastic resin with high rigidity and low toughness. A research shows that the toughness can be enhanced by reducing the recrystallization temperature; when the recrystallization temperature of the polyphenylene sulfide resin composition is lower than 220° C., higher toughness can be achieved. The recrystallization temperature of the preferable polyphenylene sulfide resin composition is lower than 220° C. 
         [0012]    In view of achieving higher toughness, further preferably, the recrystallization temperature of the polyphenylene sulfide resin composition is lower than 215° C. 
         [0013]    In view of achieving higher rigidity, the recrystallization temperature of the polyphenylene sulfide resin composition is preferably equal to or higher than 150° C., and even further preferably equal to or higher than 180° C. 
         [0014]    The polyphenylene sulfide resin composition of the invention preferably includes 50 to 200 weight parts of the deformed cross-section glass fiber (B) relative to 100 weight parts of the polyphenylene sulfide resin (A) in order to take the toughness and the rigidity into account. In view of the two aspects of the rigidity and the flowability, the polyphenylene sulfide resin composition further preferably includes 60 to 180 weight parts of the deformed cross-section glass fiber (B) and even further preferably includes 80 to 150 weight parts of the deformed cross-section glass fiber (B) relative to 100 weight parts of the polyphenylene sulfide resin (A). 
         [0015]    In view of even further improving the toughness, the polyphenylene sulfide resin composition further includes: amorphous resin (C) with the glass-transition temperature being equal to or higher than 100° C. 
         [0016]    In view of the two aspects of the toughness and the flowability, there are preferably 1.5 to 35 weight parts of the amorphous resin (C) with the glass-transition temperature being equal to or higher than 100° C. relative to 100 weight parts of the polyphenylene sulfide resin (A). In order to improve the toughness to a larger extent and guarantee the flowability, there are further preferably 2 to 25 weight parts, even further preferably 4 to 15 weight parts of the amorphous resin (C) with the glass-transition temperature being equal to or higher than 100° C. relative to 100 weight parts of the polyphenylene sulfide resin (A). 
         [0017]    The upper limit of the glass-transition temperature of the amorphous resin is not specifically defined, which can be equal to or lower than 400° C., preferably equal to or lower than 300° C. 
         [0018]    Polyphenylene Sulfide Resin (A): 
         [0019]    The polyphenylene sulfide resin (A) used in the invention can be either a polyphenylene sulfide polymer or a mixture of multiple polyphenylene sulfide polymers. In view of obtaining the polyphenylene sulfide resin composition with excellent flowability, toughness and rigidity, the mixture of multiple polyphenylene sulfide polymers is preferably adopted. 
         [0020]    The polyphenylene sulfide polymer is a polymer with a repeating unit represented by the following structural formula (I), 
         [0000]    
       
                 
         
             
             
         
       
     
         [0021]    From the viewpoint of heat resistance, the repeating unit represented by the formula (I) accounts for 70 mole percent or over of the polyphenylene sulfide polymer, preferably 90 mole percent or over. In the polyphenylene sulfide polymer, the repeating units are selected from one or more of repeating units (II), (III), (IV), (V), (VI), (VII) and (VIII) with the following structures except for the repeating unit represented by the formula (I), 
         [0000]    
       
                 
         
             
             
         
       
     
         [0022]    When the polyphenylene sulfide polymer includes one or more of the above repeating units (II), (III), (IV), (V), (VI), (VII) and (VIII), the melting point of the polyphenylene sulfide polymer is lower, and from the viewpoint of moulding, it is more favorable. 
         [0023]    In view of achieving excellent flowability, the polyphenylene sulfide polymer used in the invention further preferably has a high melting index. For example, the melting index is preferably equal to or higher than 200 g/10 min, and further preferably equal to or higher than 500 g/10 min. With regard to the upper limit, in view of achieving excellent toughness, the melting index is preferably equal to or lower than 5,000 g/10 min. 
         [0024]    The polyphenylene sulfide polymer (A) with the above structures (I) to (VIII) may be prepared by a method for achieving higher flowability, which is recorded in Japanese Examined Patent Publication No. 45-3368 or a method for achieving lower flowability, which is recorded in Japanese Examined Patent Publication No. 52-12240. The difference between the former and the latter is whether a polymerization system contains alkali metal carboxylate which is a polymerization promoter. In the former method, no alkali metal carboxylate is added into the polymerization system, so the flowability is higher; in the latter method, the alkali metal carboxylate is added into the polymerization system, so the flowability is lower, and it is favorable for the toughness of the resin. Therefore, the polyphenylene sulfide polymers prepared by the two methods can be combined for use, and the flowability and the toughness of the polyphenylene sulfide resin can be balanced. 
         [0025]    In addition, the above prepared polyphenylene sulfide polymers are subjected to end-capping treatment, thus obtaining a polyphenylene sulfide polymer with lower chlorine content. For example, the end-capping treatment is carried out by 2-mercapto benzimidazole under an alkaline condition, so that the end-capped polyphenylene sulfide polymer with lower chlorine content can be obtained. 
         [0026]    Deformed Cross-Section Glass Fiber (B): 
         [0027]    The deformed cross-section glass fiber (B) in the invention is a glass fiber, and the section of the single glass fiber is non-circular; the non-circular section can be represented by “flatness ratio”. Here, the “flatness ratio” is illustrated according to  FIG. 1 , the section diagram of the single deformed cross-section glass fiber. As shown in  FIG. 1 , it supposes that the long edge of a rectangle with a minimum area, which is circumscribed to the section of the specially-shaped glass fiber, is a, and the short edge is b, so the “flatness ratio” is represented by a ratio (a/b) of the lengths of the long edge a to the short edge b, and the flatness ratios with different values represent different types of deformed cross-section glass fibers (B). When the deformed cross-section glass fiber (B) with the flatness ratio being equal to or larger than 1.1 is adopted, the resin composition can achieve higher flowability and toughness. 
         [0028]    In view that the polyphenylene sulfide resin composition has excellent flowability and toughness, the flatness ratio of the deformed cross-section glass fiber (B) is preferably equal to or larger than 1.5. In view of the easiness of obtaining the deformed cross-section glass fiber, the flatness ratio is preferably equal to or smaller than 10; further preferably, the flatness ratio is 2 to 8, and even further preferably 2 to 4. The area of the section of the deformed cross-section glass fiber (B) is preferably 100 to 500 μm 2 /piece, and further preferably 110 to 300 μm 2 /piece. 
         [0029]    Amorphous Resin (C) with the Glass-Transition Temperature Being Equal to or Higher Than 100° C.: 
         [0030]    Under the slow action of outer force until the material is broken, the generated deformation is called a bending moment; the impact strength of the material is guaranteed, and the bending moment is increased at the same time, so its toughness may be further improved. In order to further improve the toughness of the polyphenylene sulfide resin composition, the amorphous resin (C) with the glass-transition temperature being equal to or higher than 100° C. is added into it. 
         [0031]    The amorphous resin (C) with the glass-transition temperature being equal to or higher than 100° C. may be selected from: a cycloolef in polymer, polycarbonate, polyphenyl ether, amorphous aromatic ester, polysulfone, polyether sulfone, polyetherimide, polyamideimide, polyimide or one or more of the above copolymers. Wherein in view of the heat resistance and the compatibility, the amorphous resin (C) with the glass-transition temperature being equal to or higher than 140° C. is preferably added, and may be selected from: polycarbonate, polyphenyl ether, amorphous aromatic ester, polysulfone, polyether sulfone, polyetherimide, polyamideimide, polyimide or one or more of the above copolymers. In addition, chlorine elements may be introduced into the molecular ends of polysulfone and polyether sulfone in their manufacturing processes, so that with regard to polysulfone and polyether sulfone, end-capping treatment is adopted to keep the respective chlorine content lower than 1,000 ppm. 
         [0032]    In view of achieving excellent flowability, the melting viscosity of the polyphenylene sulfide resin composition is preferably that the melting viscosity of a capillary rheometer with the shearing rate of 1,000 s −1  under 315° C. is lower than 180 Pa·s, and further preferably equal to or lower than 160 Pa·s. 
         [0033]    In view of achieving excellent toughness, the melting viscosity of the capillary rheometer is preferably equal to or higher than 80 Pa·s, and further preferably equal to or higher than 100 Pa·s. 
         [0034]    In view of two aspects, reduction of the influence on the environment and the flowability, the chlorine content of the polyphenylene sulfide resin composition is equal to or lower than 1,000 ppm. The measurement of the chlorine content refers to the European standard EN 14582: 2007. 
         [0035]    In the polyphenylene sulfide resin composition of the invention, the polyphenylene sulfide resin (A) is excellent in both rigidity and toughness. In view of the influence of the amorphous resin (C) with the glass-transition temperature being equal to or higher than 100° C. on the polyphenylene sulfide resin composition on its performance, preferably: the amorphous resin (C) with the glass-transition temperature being equal to or higher than 100° C. generates “islands” dispersion in the polyphenylene sulfide resin composition, and the “islands” are amorphous resin with irregular shapes, and are dispersed in the polyphenylene sulfide resin composition as dispersing phases. The average area of these “islands” is smaller than 1 μm 2 /piece. Further preferably: the amorphous resin (C) with the glass-transition temperature being equal to or higher than 100° C. generates “islands” dispersion in the polyphenylene sulfide resin composition, and the average area of these “islands” is smaller than 0.5 μm 2 /piece. Even further preferably: the amorphous resin (C) with the glass-transition temperature being equal to or higher than 100° C. generates “islands” dispersion in the polyphenylene sulfide resin composition, and the average area of these “islands” is smaller than 0.3 μm 2 /piece. If the average area of these “islands” formed by the amorphous resin (C) with the glass-transition temperature being equal to or higher than 100° C. is larger than 1 μm 2 /piece, the toughness improving effect is probably not obvious. 
         [0036]    The average area of the “islands” in the invention is obtained by the following method. That is, the polyphenylene sulfide resin composition is observed under a microscope, and the “islands” formed by the amorphous resin are determined by an element analysis method; the areas of any 100 “islands” are measured, and arrayed from large to small, which are a 1 , a 2 , a 3 , . . . , a 100 ; the areas of the 80 “islands” from a 11  to a 90  are subjected to arithmetic mean, and obtained values are designated as the average areas of these “islands”. In addition, if the average areas of the 80 “islands” have a large mutual deviation; then the areas of another 100 “islands” are measured, and arrayed from large to small, which are b 1 , b 2 , b 3 , . . . , b 100 ; the areas of the 80 “islands” from b 11  to b 90  and the areas of the 80 “islands” from a 11  to a 90  are subjected to arithmetic mean together, and obtained values are designated as the average areas of these “islands”. For example, the polyphenylene sulfide resin composition is injection-moulded into a standard spline (a spline mould is 10 mm in width×4 mm in thickness); the section of the spline is cut into thin sheets, and is observed under a JEM-2100F field emission high-resolution transmission electron microscope, and the magnifying power is 10,000 to 20,000 times; the “islands” formed by the amorphous resin in the polyphenylene sulfide resin composition are determined by making use of an Electron Energy Loss Spectroscopy (EELS), and the average areas of these “islands” can be calculated by Leica Qwin image analysis software, and the obtained areas divide the number of “islands” to obtain the average areas of the “islands”. The specific calculating method in the invention is as follows; the areas of any 100 “islands” are measured, and arrayed from large to small, which are a 1 , a 2 , a 3 , . . . , a 100 ; the areas of the 80 “islands” from a 11  to a 90  are subjected to arithmetic mean, and obtained values are designated as the average areas of these “islands”. 
         [0037]    In addition, within a scope of not damaging the effect of the invention, the polyphenylene sulfide resin composition further includes an elastomer. By the adding of the elastomer which can be cooperated with the amorphous resin (C), the toughness of the polyphenylene sulfide resin composition is even further improved. 
         [0038]    The elastomer can be listed as follows: one or more of an olefin elastomer, a modified olefin elastomer and a styrene elastomer.

         [0040]    For example, the olefin elastomer includes: independent alpha-olefins such as ethylene, propylene, 1-butene, 1-amylene, 4-methyl-1-amylene and isobutene or a polymer or a copolymer obtained by polymerization of multiple alpha-olefins above, and a copolymer of alpha-olefin and alpha, beta-unsaturated acids such as acrylic acid, methyl acrylate, ethyl acrylate, butyl acrylate, methacrylic acid, methyl methacrylate, ethyl methacrylate and butyl methacrylate and alkyl ester thereof.

         [0047]    (3) The Styrene Elastomer: 
         [0048]    The styrene elastomer may be listed as follows: a styrene/butadiene copolymer, a styrene/ethylene/butadiene copolymer, a styrene/ethylene/propylene copolymer, or a styrene/isoprene copolymer; in view of the compatibility, the styrene/butadiene copolymer is preferred. 
         [0049]    In view of two aspects, the flowability and toughness, the total weight part of the elastomer is preferably: 0.5 to 20 weight parts relative to 100 weight parts of the polyphenylene sulfide resin (A), and further preferably 0.8 to 10 weight parts, even further preferably 1 to 6 weight parts; in addition, within the scope of not affecting the effect of the invention, multiple elastomers can be combined for use. 
         [0050]    In addition, within the scope of not damaging the effect of the invention, the polyphenylene sulfide resin composition further includes one or more of compatilizers such as a silane compound and a titanic acid type compound. 
         [0051]    The silane compound may be listed as follows: one or more of an epoxy group-containing alkoxy silane compound such as gamma-epoxy glycero-propyl trimethoxy silane, gamma-epoxy glycero-propyl triethoxysilane, or beta-(3,4-epoxy cyclohexyl)ethyl trimethoxy silane, a sulfydryl-containing alkoxy silane compound such as gamma-sulfydryl propyl trimethoxy silane and gamma-sulfydryl propyl methyldimethoxysilane, a ureido-containing alkoxy silane compound such as gamma-ureido propyl triethoxysilane, gamma-ureido propyl trimethoxy silane, or gamma-(2-ureido ethyl)amino propyl trimethoxy silane, an isocyanate group-containing alkoxy silane compound such as gamma-isocyanate propyl trimethoxy silane, gamma-isocyanate propyl methyl dimethoxy silane, gamma-isocyanate propyl diethoxymethylsilane, gamma-isocyanate propyl ethyl dimethoxy silane, gamma-isocyanate propyl diethoxymethylsilane, gamma-isocyanate propyl diethyldiethoxysilane, or gamma-isocyanate propyl trichlorosilane, an amino-containing alkoxysilane compound such as gamma-(2-amino ethyl)amino propyl methyl dimethoxy silane, gamma-(2-amino ethyl)amino propyl methyl trimethoxysilane, or gamma-amino propyl trimethoxy silane, and a hydroxyl-containing alkoxy silane compound such as gamma-hydroxyl propyl trimethoxy silane, or a gamma-hydroxyl propyl triethoxysilane.

         [0053]    In view of the compatibility combined with the flowability and the toughness, there are totally preferably 0.01 to 3 weight parts of the silane compound and/or the titanate compound relative to the 100 weight parts of the polyphenylene sulfide resin (A), further preferably 0.05 to 2 weight parts, and even further preferably 0.1 to 2 weight parts. By the adding of such a compatilizer, the excellent flowability of the polyphenylene sulfide resin composition can be guaranteed, and its toughness is improved. If the weight part of the compatilizer is lower than 0.01, the compatible effect may not be achieved; if the weight part is larger than 3, the flowability of the polyphenylene sulfide resin composition may be reduced, and the gas amount may be increased during injection moulding. In addition, within the scope of not affecting the effect of the invention, multiple silane compounds or multiple titanate compounds can be combined for use. 
         [0054]    In addition, within the scope of not damaging the effect of the invention, the polyphenylene sulfide resin composition may contain an antioxidant, thus further improving the heat resistance and the heat stability of the resin composition. The antioxidant can be either a phenol oxidant or a phosphorus type antioxidant. 
         [0055]    (1) The Phenol Oxidant:

         [0057]    (2) The Phosphorus Type Antioxidant 
         [0058]    The phosphorus type antioxidant may be listed as follows: one or more of di(2,6-ditertiary butyl-4-methyl phenyl)pentaerythritol-diphosphite, di(2,4-ditertiary butyl phenyl)pentaerythritol-diphosphite, di(2,4-dicumenyl phenyl)pentaerythritol-diphosphite, tri(2,4-ditertiarybutyl phenyl)phosphite ester, tetra(2,4-ditertiary butyl phenyl)-4,4′-diphenylene phosphite ester, distearoyl pentaerythritol-diphosphite, triphenyl phosphite ester, or 3,5-dibutyl-4-hydroxy benzyl phosphate diethyl ester. 
         [0059]    There are 0.01 to 3 weight parts of antioxidant relative to 100 weight parts of the polyphenylene sulfide resin (A), preferably 0.05 to 2 weight parts, and more preferably 0.1 to 1 weight part. 
         [0060]    In addition, within the scope of not affecting the effect of the invention, the polyphenylene sulfide resin composition further contains other components, for example: one or more of a filler (silicon dioxide, calcium carbonate, magnesium hydroxide, aluminum hydroxide, calcium hydroxide, glass beads, hollow glass micro beads, ceramic beads, boron nitride, molybdenum disulfide, wollastonite, aluminum oxide, graphite, metal powder, carbon powder, carbon nanotubes, potassium titanate whisker, aluminum borate whisker, oxygen gypsified zinc whisker, silicon carbide fibers, ceramic fibers, asbestos fibers, gypsum fibers, metal fiber polyacrylonitrile or asphalt carbon fibers, or mica, wherein in view of corrosion prevention, lubrication and durability, the calcium carbonate, the graphite, the glass beads, the hollow glass micro beads or the silicon dioxide are preferred, and particularly the calcium carbonate is most preferred), a demoulding agent (montanic acid and metal salt thereof, ester thereof, semi-ester thereof, stearyl alcohol, stearamide, amides, biurea or polyethylene wax, wherein in view of reduction of gas production during moulding, the amides is preferred), a pigment (cadmium sulfide, phthalocyanine or coloring carbon black masterbatch, etc.) a dye (nigrosine, etc.), a seed agent (talcum powder, titanium dioxide, kaoline, clay, or polyether-ether-ketone, etc.), a plasticizer (p-hydroxy octyl benzoate, or N-butylbenzenesulfonamide), an antistatic agent (an alkyl sulfate anion antistatic agent, a quaternary ammonium salt cation antistatic agent, a polyoxyethylene sorbide monostearate non-ionic antistatic agent, or a betaine amphiprotic antistatic agent), and a flame retardant (hydroxides such as red phosphorus, phosphate, melamine cyanurate, magnesium hydroxide and aluminum hydroxide, ammonium polyphosphate, brominated polystyrene, brominated polyphenyl ether, brominated polycarbonate, brominated epoxy resin or a combination of these bromine flame retardants and antimonous oxide). 
         [0061]    By the invention, the polyphenylene sulfide resin composition with low chlorine content and excellent flowability can be obtained and is particularly suitable for a thin-wall product with high toughness and high rigidity. 
         [0062]    Therefore, the invention further provides a moulding prepared from the polyphenylene sulfide resin composition. 
         [0063]    The thickness of the moulding is equal to or lower than 1.5 mm. The moulding with the thickness is a moulding that the ratio of the projection area of the thickness part (equal to or lower than 1.5 mm) to the orthographic projection area of the moulding is 50 percent or over. 
         [0064]    The crystallization degree of the moulding is lower than 50 percent, which is an arithmetic mean value of the crystallization degrees of the positions, close to a pouring gate, on the upper and lower surfaces of the moulding. 
         [0065]    The moulding prepared from the polyphenylene sulfide resin composition is excellent in rigidity and toughness in the thickness direction, high in moulding performance and high in mechanical strength, and is particularly suitable for products for forming frames of a portable computer, a mobile phone and a portable electronic device. 
         [0066]    For the polyphenylene sulfide resin composition, high rigidity can be achieved under high crystallization degree. In view of the crystallization degree, the mould temperature during injection moulding is generally 130 to 160° C. Under such mould temperature, the crystallization degree of the moulding is 50 percent or over. Although the rigidity is improved, the toughness is reduced. Under such a circumstance, it is necessary to carry out injection moulding by low mould temperature; however, under the low mould temperature, there are the risks of reducing the crystallization degree and lowering the rigidity. A research shows that by the adoption of the polyphenylene sulfide resin composition, injection moulding is carried out under the mould temperature below the glass-transition temperature of the polyphenylene sulfide resin (A), and in view of convenience for moulding, the temperature is preferably 5 to 95° C., so that the moulding of which the crystallization degree is equal to or larger than 20 percent and smaller than 50 percent and both the rigidity and the toughness are high can be obtained from the polyphenylene sulfide resin composition. 
         [0067]    Therefore, the invention further provides a manufacturing process of the moulding from the polyphenylene sulfide resin composition. A cut plastic thin film is firstly put into the mould by an in-mould insert injection or in-mould transfer moulding technology, and then the polyphenylene sulfide resin composition is moulded by an injection moulding machine. The mould temperature is lower than the glass-transition temperature of the polyphenylene sulfide resin (A). In view of convenience for moulding, the mould temperature is preferably 5 to 95° C. 
         [0068]    The polyphenylene sulfide resin composition according to the invention is excellent in flowability, low in chlorine content, low in influence on the environment and obvious in advantage during injection moulding of a thin product with high toughness and rigidity, and is particularly suitable for moulding the products for forming frames of a light, thin and firm portable computer, a mobile phone and a portable electronic device.

         [0137]    Test of Recrystallization Temperature and Crystallization Degree: 
         [0138]    2 to 3 mg of the polyphenylene sulfide resin composition particles which were extruded to be granulated and dried was cut with a cutter; for a moulding, a small sheet (which is 0.5 mm in thickness) was cut off with the cutter along the surface from a position near to the pouring gate at 2 cm, and was recorded as a lower surface section. Then a small sheet (which is 0.5 mm in thickness) was cut off with the cutter along the surface from the back surface of one side of the pouring gate, followed by scraping off the plastic thin film on its surface with the cutter, and the small sheet was recorded as an upper surface section. Testing was performed for the recrystallization temperatures and the crystallization degrees of the materials cut by the cutter or the upper and lower surface sections of the moulding according to the procedure below: recording the recrystallization temperature and the crystallization degree of the material cut from the particle as the recrystallization temperature and the crystallization degree of the polyphenylene sulfide resin composition, and recording arithmetic mean values of the recrystallization temperatures and the crystallization degrees of the upper and lower surface sections as the recrystallization temperature and the crystallization degree of the moulding. 
         [0139]    The polyphenylene sulfide resin composition particles were put into a sample disk of a TA-Q100 differential scanning calorimeter (DSC), and the cut weight (mg) was inputted into the procedure, followed by heating from the room temperature to 340° C. under the nitrogen atmosphere at the heating rate of 20° C./min, stabilizing the temperature for 3 minutes, eliminating the heat history, and this step was recorded as cycle 1; cooling from 340° C. to the room temperature at the cooling rate of 20° C./min, and this step was recorded as cycle 2; heating from the room temperature to 340° C. at the heating rate of 20° C./min again, stabilizing the temperature for 3 minutes, and this step was recorded as cycle 3; cooling from 340° C. to the room temperature at the cooling rate of 20° C./min again, and this step was recorded as cycle 4. A crystallization peak in the cycle 4 was integrated by integrating software of the DSC, thus the recrystallization temperature and the area S of the crystallization peak was obtained. In addition, the content by weight of the polyphenylene sulfide resin composition particles for DSC test or the polyphenylene sulfide resin in the moulding was recorded as w (%), and the crystallization degree was calculated according to formula (1).

         [0140]    The glass-transition temperature refers to: Polymer Handbook, version IV, J. Brandrup etc., published by Wiley-Interscience, 1999. 
         [0141]    Form Observation: 
         [0142]    The amorphous resin (C) was dispersed in the polyphenylene sulfide resin composition. 
         [0143]    The polyphenylene sulfide resin composition was injection-moulded into a standard spline (a spline mould is 10 mm in width×4 mm in thickness) ; the section of the spline was cut into thin sheets, and was observed under a JEM-2100F field emission high-resolution transmission electron microscope, and the magnifying power was 10,000 to 20,000 times; the “islands” formed by the amorphous resin in the polyphenylene sulfide resin composition were determined by making use of an Electron Energy Loss Spectroscopy (EELS), and the average areas of these “islands”could be calculated by Leica Qwin image analysis software, and the obtained areas divided the number of “islands” to obtain the average areas of these “islands”. The specific calculating method in the invention was as follows: the areas of any 100 “islands” were measured, and arrayed from large to small, which are a 1 , a 2 , a 3 , . . . , a 100 ; the areas of the 80 “islands” from a 11  to a 90  were subjected to arithmetic mean, and obtained values were designated as the average areas of these “islands”. 
         [0144]    Test of the Rigidity and Toughness Performances: 
         [0145]    Measuring a bending modulus and a bending moment with an injection-moulded standard spline according to the standard ISO0178, wherein the bending rate is 2 mm/rain, and a mean value is obtained from every group of 5 splines. 
         [0146]    Measuring the Charpy notched impact strength with the injection-moulded standard spline according to the standard ISO0179, wherein a mean value was obtained from every group of 5 splines. 
         [0147]    The bending modulus reflected the rigidity of the polyphenylene sulfide resin composition; if the modulus was large, the rigidity was high, and otherwise, the rigidity was low. 
         [0148]    The Charpy notched impact strength reflected the toughness of the polyphenylene sulfide resin composition under instant impact; if the strength was higher, the impact strength of the material was high; the bending moment was a deformation produced by slowly applying outer force to the material until the material was broken, and reflected the ductility of the material. It was a measure of improving the toughness of the material to guarantee the Charpy notched impact strength of the material while improving the bending moment of the material. 
       EXAMPLES 1 TO 27 
       [0149]    The raw materials were as shown in Table 1-1, Table 1-1 (continuation), Table 2-1 and Table 2-1 (continuation) Granulation was realized by a TEX30a type biaxial extruder (L/D=45.5) made by Japan Steel Works, LTD., and the extruder had 13 heating regions and was provided with two material feeding devices with meters and vacuum exhaust equipment. Except for the glass fiber, other raw materials were fed from a main material feeding opening of the extruder after being mixed in a high-speed mixing machine, and the glass fiber was added from a side material feeding opening of the extruder; the extruder temperature was set to be 200 to 330° C., and the granular polyphenylene sulfide resin composition was obtained by melting, extrusion, cooling and granulation; the granular object was dried in a drying oven with the temperature of 130° C. for 3 hours, and was moulded into a spline meeting the ISO standard (a spline mould was 10 mm in width×4 mm in thickness), and the performance test was performed according to the above test method. Table 1-2, Table 1-2 (continuation), Table 2-2 and Table 2-2 (continuation) records physical property measurement results of the respective Examples. 
         [0150]    When the Example 21 was compared with the Example 13, no amorphous resin polyetherimide (C) with the glass-transition temperature being equal to or higher than 100° C. was added, so no “islands” formed by the amorphous resin in the polyphenylene sulfide resin composition could be observed. The Charpy notched impact strength of the polyphenylene sulfide resin composition was 11 kJ/m 2 , which was lower than 13 kJ/m 2  of the Example 13; the bending moment of the polyphenylene sulfide resin composition was 2.3 mm, which was lower than 3.2 mm of the Example 13. 
         [0151]    When the Example 22 was compared with the Example 15, the content by weight of the deformed cross-section glass fiber (B) was increased, and there were 225 weight parts of deformed cross-section glass fiber (B) relative to 100 weight parts of polyphenylene sulfide resin (A). The melting viscosity of the capillary rheometer of the polyphenylene sulfide resin composition was 169 Pa·s, and the flowability was reduced; the bending modulus of 28 GPa and the Charpy notched impact strength of 19 kJ/m 2  were higher than the bending modulus of 17 GPa and the Charpy notched impact strength of 13 kJ/m 2  of the Example 15, but its bending moment was 2.0 mm, which was lower than the bending moment of 3.2 mm of the Example 15. 
         [0152]    When the Example 23 was compared with the Example 16, the weight part of the amorphous resin polyamideimide (C) was reduced, which was 0.5 weight part, relative to 100 weight part of the polyphenylene sulfide resin (A). The Charpy notched impact strength of the polyphenylene sulfide resin composition was 11 kJ/m 2 , which was lower than that of 14 kJ/m 2  of the Example 16, and the bending moment of the polyphenylene sulfide resin composition was 2.4 mm, which was lower than that of 3.3 mm of the Example 16. 
         [0153]    When the Example 24 was compared with the Example 13, polyetherimide was replaced with polystyrene (which was amorphous resin and had the glass-transition temperature of 95° C.), and no “island” formed by polystyrene in the polyphenylene sulfide resin composition was observed, it speculated that polystyrene was degraded in an extrusion process. The melting viscosity of the capillary rheometer of the polyphenylene sulfide resin composition was 185 Pa·s, which was higher than that of 120 Pa·s of the Example 13, so the flowability was reduced; its bending modulus was 14 GPa, which was lower than that of 16 GPa of the Example 13, so the rigidity was lowered; its Charpy notched impact strength was 10 kJ/m 2 , which was lower than that of 13 kJ/m 2  of the Example 13, and its bending moment was 2.7 mm, which was lower than that of 3.2 mm of the Example 13, so the toughness was lowered. 
         [0154]    When the Example 25 was compared with the Example 13, no silane compound serving as a compatilizer was added, and the average area of the “island” was observed to be 1.5 μm 2 ; the Charpy notched impact strength was 11 kJ/m 2 , which was lower than that of 13 kJ/m 2  of the Example 13, and the bending moment was 2.9 mm, which was lower than that of 3.2 mm of the Example 13, so the toughness was lower than that of the Example 13. 
         [0155]    When the Example 27 was compared with the Example 13, a small amount of silane compound serving as a compatilizer was added, and the average area of the “island” was observed to be 0.9 μm 2 ; the Charpy notched impact strength was 11 kJ/m 2 , which was lower than that of 13 kJ/m 2  of the Example 13, and the bending moment was 3.0 mm, which was lower than that of 3.2 mm of the Example 13, so the toughness was lower than that of the Example 13. 
         [0156]    When the Example 26 is compared with the Example 13, no elastomer was added; the Charpy notched impact strength of the polyphenylene sulfide resin composition was 12 kJ/m 2 , which was slightly lower than that of 13 kJ/m 2  of the Example 13, and the bending moment was 2.8 mm, which was lower than that of 3.2 mm of the Example 13, so the toughness was lower than that of the Example 13. 
       COMPARATIVE EXAMPLE 1 
     The Chlorine Content of the Polyphenylene Sulfide Resin Composition was Larger Than 1,000 ppm 
       [0157]    The preparation method of the Comparative Example 1 was the same as the preparation methods of the Examples 1 to 27. The raw materials are as shown in Table 1-1 (continuation), and the physical property measurement results are as shown in Table 1-2 (continuation). The chlorine content of the polyphenylene sulfide resin composition is equal to or larger than 1,000 ppm; although its flowability is higher, and the melting viscosity of the capillary rheometer is 91 Pa·s, both the modulus and the Charpy notched impact strength are low, which are respectively 9 GPa and 9 kJ/m 2 , so the rigidity and the toughness are low. 
       COMPARATIVE EXAMPLES 2 AND 3 
     Circular-Section Glass Fiber was Adopted 
       [0158]    The preparation methods of the Comparative Examples 2 and 3 were the same as the preparation methods of the Examples 1 to 27. The raw materials were as shown in Table 2-1 (continuation), and the physical property measurement results are as shown in Table 2-2 (continuation). 
         [0159]    As a Comparative Example of the Example 21, the Comparative Example 2 manufactured the polyphenylene sulfide resin composition by the circular-section glass fiber. Therefore, the Charpy notched impact strength of the polyphenylene sulfide resin composition was extremely low, which was 7 kJ/m 2  and lower than that of 11 kJ/m 2  of the Example 21, and the bending moment of the polyphenylene sulfide resin composition was extremely low, which was 1.5 mm and lower than that of 2.3 mm of the Example 21, so the toughness of the polyphenylene sulfide resin composition was lower. 
         [0160]    As a Comparative Example of the Example 17, the Comparative Example 3 manufactured the polyphenylene sulfide resin composition by the circular-section glass fiber. Therefore, the melting viscosity of the capillary rheometer of the polyphenylene sulfide resin composition was enhanced, which was 155 Pa·s, so the flowability was lowered; its Charpy notched impact strength was extremely low, which was 9 kJ/m 2  and lower than that of 13 kJ/m 2  of the Example 17, and its bending moment was 2.3 mm, which was lower than that of 3.1 mm of the Example 17, so the toughness was lower. 
       EXAMPLES 28 TO 33 
       [0161]    In the Examples 28 to 33, an in-mould insert injection moulding technology was adopted to prepare a moulding with a plastic thin film on the surface. Firstly, a cut Polyethylene Terephthalate (PET) thin film (length 380 mm×width250 mm) was put into a mould, and the temperature of mould was as shown in Table 3-1; then an injection moulding machine injected the granular polyphenylene sulfide resin composition obtained in the Example 13 into the PET thin film in the mould, thus obtaining the moulding (length 380 mm×width 250 mm×thickness 1.3 mm) with the PET thin film on the surface. 
         [0162]    The rectangular spline (length 100 mm×width 13 mm×thickness 1.3 mm) was cut from the obtained moulding from the pouring line along the width direction, and was subjected to tests on the crystallization degree, the bending moment and the bending modulus, and results are as shown in Table 3-1. For the Examples 28 to 33, with the temperature of the mould reduced from 90° C. to 10° C., the crystallization degree was reduced from 48 percent to 22 percent, the bending moment was increased from 8.5 mm to 11.2 mm, and the bending modulus was unchanged.
