     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The invention relates to an isocyanate trimer and a method of preparing the same, and more particularly an isocyanate trimer modified with silane or functional polysiloxane and a method of preparing the same. 
         [0004]    2. Description of the Related Art 
         [0005]    Nowadays, silicone-modified polyurethane has aroused more and more attention in academy and industry. While maintaining the original excellent performance, silicone-modified polyurethane exhibits improved properties such as adhesion, wear resistance, chemical resistance, heat resistance, weather resistance, electrical insulation, fire retardancy, and hydrophobicity, and can be cured at room temperature. However, the above-mentioned silicone-modified polyurethane mainly focuses on the modification of an isocyanate prepolymer. There are few reports on silicone-modified isocyanate trimer. 
         [0006]    The study on preparation and application of isocyanate trimers has been very active. U.S. Pat. Nos. 2,801,244, 5,264,572, 0,109,665, 6,515,125, and 3,996,223 separately discloses a method of preparing an isocyanate trimer, all of which have different yield under different catalytic system. Isocyanate trimers have a high application value and are mainly used in coatings, adhesives, sealants, elastomers, foam plastics and so on, particularly for current production of quick-drying and highly decorative furniture and automobile. However, most isocyanate trimers are solid at room temperature, except that hexamethylene diisocyanate (HDI) trimer is liquid. Therefore, to develop an isocyanate trimer with high compatibility is of great significance. 
       SUMMARY OF THE INVENTION 
       [0007]    In view of the above-described problems, it is one objective of the invention to provide a modified isocyanate trimer featuring high compatibility. Polyurethane or other polymers (for example, epoxy resins, polymethacrylate, polyacrylamide, and phenolic resin) prepared by the modified isocyanate trimer can improve the heat resistance, weather resistance, electrical insulation, fire retardancy, and hydrophobicity. 
         [0008]    It is another objective of the invention to provide a method of preparing the modified isocyanate trimer featuring high compatibility.

         [0000]    
       
                 
         
             
             
         
       
     
         [0000]    —S—, or —O—, and m is an integer from 0 to 30. 
         [0028]    In a class of this embodiment, the catalyst is an organic tin compound including but not limited to dibutyltin dilaurate, dibutyltin maleate, dibutyltin diacetate, dibutyltin dilaurylmercaptan, and dimethyltin dichloride. 
         [0029]    In a class of this embodiment, the amount of the catalyst is between 0.01 and 0.5 weight % of the total amount of the trimer and silicon compound. 
         [0030]    In a class of this embodiment, the inert organic solvent which does not react with the reactants is hydrocarbon, chlorinated hydrocarbon, ester, or ether. 
         [0031]    In a class of this embodiment, the hydrocarbon solvent is petroleum ether, linear or branched hydrocarbon with low boiling point, benzene, toluene, or xylene; the chlorinated hydrocarbon is chloroform, chlorobenzene, dichloromethane, or dichloroethane; ester is ethyl acetate; and ether is aether or tetrahydrofuran. 
         [0032]    In a class of this embodiment, a molar ratio of the isocyanate trimer to the active hydrogen of silane or polysiloxane is 1:1. 
         [0033]    Advantages of this invention are summarized below:
       1. The isocyanate trimer modified with silanes or functional polysiloxanes has low viscosity, low volatile, low toxicity, high functionality, and high tolerance against xylene due to reduced isocyanate polarity, so that the compatibility of trimer with hydroxy resin has been improved significantly. In addition, heat resistance, weather resistance, and adhesion of isocyanate trimer have been further increased due to the introduction of organic silicon.   2. For the isocyanate trimer modified with silanes or functional polysiloxanes of the invention, isocyanate as a reactive functional group can react with polyester diols, polyether diols, hydroxy resins, and other polyols, and siloxane as another reactive functional group can react with inorganic materials or hydroxyl resins to form chemical bonds. In addition, the isocyanate trimer modified with silane or functional polysiloxane can be designed properly in accordance with the type of a polyol or polyol resin, which benefits the combination thereof.   3. For the reaction between isocyanate and active hydrogen of silanes or functional polysiloxanes to prepare carbamate, the introduction of an organometallic catalyst such as dibutyltin dilaurate can help obtain a high yield of product at low temperature (between −50° C. and 30° C.). Particularly, in case it is difficult for isocyanate trimer to react with active hydrogen of silanes or functional polysiloxanes due to space block, or the occurrence of a large amount of by-products at high temperature, the introduction of organic tin catalysts can smooth the reaction.       
 
         [0037]    A monomer of the isocyanate trimer is selected from toluene diisocyanate (TDI), methylene diphenyl diisocyanate (MDI), hexamethylene diisocyanate (HDI), isophorone diisocyanate (IPDI), 1,4-diisocyanate-2,2,6-trimethyl cyclohexane (TMCDI), 4,4-bis(isocyanatecyclohexyl)methane (HMDI), etc. 
         [0038]    The silanes or functional polysiloxanes of the invention optionally have sulfhydryl, amino, diamino, triamino, secondary amino, hydroxy, hydroxyalkylamino, phenylamino, ureaalkyl, epoxy, N-alkyl amino, and N,N,N′,N′-tetraalkyl guanidine with hydroxyl. 
         [0039]    Particularly, a molar ratio of isocyanate trimer to the active hydrogen of silane or polysiloxane is 1:1. 
         [0040]    In one embodiment of the invention, dibutyltin dilaurate, dibutyltin maleate, dibutyltin diacetate, dibutyltin dilaurylmercaptan, and dimethyltin dichloride is used as catalyst. 
         [0041]    The reaction can be completed in a chlorinated alkyl solvent such as chloroform, cholorbenzene, dichloromethane, and dichloroethane, in an ether solvent such as aether, tetrahydrofuran, and cycloether, and in a hydrocarbon solvent such as petroleum ether, benzene, toluene, and xylene. 
         [0042]    The isocyanate trimers of the invention have good compatibility with acrylic resin. As additives, the isocyanate trimers make acrylic resin with good gloss, scratching and wear resistance, water resistance, solvent resistance, chemical resistance, weather resistance, heat resistance, gloss retention, and good flexibility. In addition, it is also an important modifier of polyurethanes, epoxy resins, polyacrylamides, phenolic resins, etc.

       [0077]    To a four necked flask (500 mL) equipped with a thermometer, a reflux condenser, a stirrer, and a funnel, 128 g of the compound 89, 46.5 g of polycarbonate diol (Mn=1000), 6 g of polyethyleneglycol adipate (Mn=2000), 6 g of dimethyopropionic acid, 14 g of N-methylpyrrolidone, 0.4 g of DBTDL, and 10 g of acetone were separately added. The mixture was allowed to react at 70° C. until the amount of free isocyanate was less than 0.5 weight %, and thereby a polyurethane prepolymer was obtained. The prepolymer was cooled to 40° C., and then 6 g of triethylamine was added dropwise for neutralizing, 120 g of deionized water added for shearing, and 2 g of ethyldiamine added for chain extension. Finally, acetone was removed under reduced pressure distillation to yield a polyurethane emulsion with solid content of 42 weight %.
