         [0022]    the inhibitor is at least one of alkynol compounds and alkenyl-containing cyclic siloxane oligomers. 
         [0023]    According to the embodiments of the present invention, preferably, the platinum-group metal catalyst is one of chloroplatinic acid, alcohol-modified chloroplatinic acid, platinum-vinyl siloxane composition, chloroplatinic acid-alkene complex and platinum-alkene composition. 
         [0024]    As an addition type catalyst, a platinum group metal catalyst needs to have good storage stability and have better compatibility with a gel and suitable catalytic activity. The range of the content thereof is 0.0005-0.6%, which is specifically decided by the content of platinum. 
         [0025]    The addition amount of a catalyst only needs to satisfy the requirement of serving as a catalyst for a hydrosilylation reaction effectively, and the amount can be changed according to a desired curing rate. If the amount is too large, the reaction will become uneconomical. 
         [0026]    Using the above-mentioned further solution has the beneficial effects that: a silicon-hydrogen addition reaction can be regulated by selecting a suitable catalyst, to prepare gels in different curing conditions as requested, and the gels can be made to have some flame retardant properties by appropriately increasing the amount of the platinum catalyst. 
         [0027]    According to the embodiments of the present invention, preferably, the platinum-group metal catalyst is platinum-vinyl siloxane composition. 
         [0028]    According to the embodiments of the present invention, preferably, the inhibitor is selected from 3-methyl-1-butyn-3-ol, 3-methyl-1-pentyn-3-ol, 3,5-dimethyl-1-hexyn-3-ol, 1-hexynyl-1-cyclohexanol, 3-phenyl-1-butyn-3-ol, 2-methyl-3-butyn-2-ol, tetravinyl tetramethylcyelo tetrasiloxane, pyridine and unsaturated acylamide. The vulcanization speed can be regulated by adding an inhibitor, to satisfy suitable working time and storage life, thereby ensuring the requirement of storage stability of silicone gel. The optimal mole ratio of the inhibitor alkynol to the platinum group metal catalyst is 40, if the mole ratio is too high, the surface of the gel is not smooth, and if the mole ratio is too low, the curing speed is too fast, which causes the reduction of working time and is not economical. 
         [0029]    According to the embodiments of the present invention, preferably, alkenyl in the compound conforming to general formula (1) is vinyl, allyl, butenyl, pentenyl, hexenyl or heptenyl. 
         [0030]    According to the embodiments of the present invention, preferably, R 1  and R 2  in the compound conforming to general formula (1) represent methyl, and R 3  and R 4  represent vinyl, wherein the content of vinyl is 0.005-0.5 wt %; and the viscosity of the compound conforming to general formula (1) is 300-30,000 cP; Using the technical solution has the advantages that: as a base material, a linear vinyl silicone oil can regulate the viscidity of a product, double bonds are concentrated at both ends, a main chain of a molecule is alkane with a long chain, a side chain has no substituent group, and internal friction resistance generated by the molecule during segment motion is less, thereby reducing internal consumption. 
         [0031]    Alternatively, R 1  in the compound conforming to general formula (1) represents methyl, and R 2 , R 3  and R 4  represent vinyl, wherein the content of vinyl is 0.01-10 wt %; and the viscosity of the compound conforming to general formula (1) is 50-10,000 cP; Using the technical solution has the advantage that: vinyl of the side group can increase more crosslinking points, thereby improving glass strength of the final gel and other mechanical properties. 
         [0032]    Alternatively, R 1 , R 2  and R 3  in the compound conforming to general formula (1) represent methyl, and R 4  represent vinyl, wherein the content of vinyl is 0.001-0.5 wt %; and the viscosity of the compound conforming to general formula (1) is 500-10,000 cP. Using the technical solution has the advantages that: for the gel, the viscidity of the gel is regulated by a plasticizer, the properties of the gel on an optical device are influenced seriously since using polydimethylsiloxane without a reactive and active group may cause oil leakage in a long-term condition, while a linear silicone oil with a reactive and active group at a single end not only can regulate the final viscosity of a product, but also can be used as a reactive group to conduct reaction, which may not cause oil leakage of the final product. 
         [0033]    According to the embodiments of the present invention, preferably, R 5  and R 8  in the compound conforming to general formula (5) represent methyl, and R 6  and R 7  represent hydroxyl, wherein the content of hydrogen contained in the compound conforming to general formula (5) is 0.005-1 wt %; and the viscosity of the compound conforming to general formula (5) is 5-200 cP; Using the technical solution has the advantages that: the linear hydroxyl -containing silicone oil can be used as a crosslinker and can also be used as a chain extender, and polymethylhydrosiloxane packaged by a Me 3 SiO 0.5  chain link therein can be used as an anti-yellowing agent. Active hydrogen-endcapped organic hydrogen-containing polysiloxane has higher activity, and the strength and toughness of the silicone gel can be improved by regulating the addition amount thereof, so that the product has good mechanical properties. 
         [0034]    Alternatively, R 6 , R 7  and R 8  in the compound conforming to general formula (5) represent methyl, and R 5  represents hydroxyl, wherein the content of hydrogen contained in the compound conforming to general formula (5) is 0.005-2 wt %; and the viscosity of the compound conforming to general formula (5) is 10-100 cP; Using the technical solution has the advantages that: hydroxyl of the side group can increase more crosslinking points, and therefore, the crosslink density is high, thereby improving the strength and toughness of the final gel and other mechanical properties. 
         [0035]    Alternatively, R 8  in the compound conforming to general formula (5) represents methyl, and R 5 , R 6  and R 7  represent hydroxyl, wherein the content of hydrogen contained in the compound conforming to general formula (5) is 0.001-10 wt %; and the viscosity of the compound conforming to general formula (5) is 10-300 cP. Using the technical solution has the advantages that: the hydrogen-containing silicone oil can provide the mass fraction of active hydrogen which can be controlled, and the higher the mass fraction of the active hydrogen is, the more the active points participating in a crosslinking reaction are, the higher the reaction activity is, and the larger the crosslink density is. The surface of a crosslinking agent has some autoadhesion by regulating the type and dosage of a crosslinking composition, so that the crosslinking agent is attached to the surface of the device. The proportion of silicon hydrogen to vinyl is generally regulated to 0.5-1.0 using the above-mentioned base material. 
         [0036]    According to the embodiments of the present invention, preferably, in the MQ resin, R 9  represents methyl, wherein the ratio of M to Q of the MQ resin is 0.6 to 1.2; Using the technical solution has the advantages that: methyl MQ resin has certain heat resistance and low-temperature resistance, has certain flexibility, is hard, but is not fragile, and has aging resistance, ultraviolet resistance and water resistance, and can reduce the linear shrinkage rate of the final product because of no active group, so that the methyl MQ resin can be used on the optical device better. 
         [0037]    Alternatively, in the MQ resin, R 9  represents vinyl, wherein the content of vinyl is less than or equal to 10 w %. Using the technical solution has the advantages that: as a reinforcing agent, vinyl MQ resin has good compatibility and dispersibility, and a siloxane link has a reinforcing effect and can react with the crosslinker, to generate firm chemical bonding, thereby improving the mechanical properties. The vinyl MQ resin is also used as a tackifier, with the addition of the MQ resin, an organic chain link can be introduced, which plays a tackifying role, without influencing the viscosity of a system, influencing light transmittance and changing the brittleness temperature of a base gel, so that the vinyl MQ resin keeps good low-temperature adhesion, and may not loss adhesion even if achieving a glass transition temperature, and the better compatibility and light transmittance thereof satisfy the requirement of use on the optical device. The mechanical properties and flame resistance properties of silicone gel are improved by regulating the crosslink density, so that the vinyl MQ resin has better high and low-temperature resistance properties, thereby keeping the inherent adhesive strength and flexibility. 
         [0038]    According to the embodiments of the present invention, preferably, the ratio of M to Q of the MQ resin is 0.8. If the M/Q ratio is small, the manufacture is difficult, and it is easy to gel, while if the M/Q ratio is large, the MQ resin is liquid, the molecular weight is low, and the cohesive energy between molecules is reduced, so that the mechanical properties cannot be improved better. 
         [0039]    The silicone gel has adhesiveness from a non-crosslinking functional group on the surface, and the product displays adhesiveness by adding an MQ resin tackifying composition, or regulating the addition amount of non-reactive adhering compositions, the side chain length of a non-crosslinking functional group, the type of an end functional group, and the like. When being a solid white powder, the MQ resin needs to be mixed with vinyl end silicone oil to form a liquid mixture, the proportion of mixture of resin to silicone oil is 0.3:0.7, selectively, 0.4:0.6. 
         [0040]    1. In the above-mentioned solution, the method for measuring the hydrogen content of the hydrogen-containing silicone oil refers to the article entitled “HNMR measurement of hydrogen content and molecular weight of hydrogen-containing silicone oil” issued in Chinese Journal of Spectroscopy Laboratory, Vol. 28, Iss 3. 
         [0041]    Since the above-mentioned technical solution is used, the present invention has the following advantages and effects as compared with the prior art: 
         [0042]    1. The present invention relates to a two-component addition type transparent AB silicone gel adhesive (hereafter referred to as a silicone gel adhesive), which has good adhesion to glass, a PC board, PMMA, and these materials are frequently-used materials for touchscreen cover plates. The silicone gel adhesive has the characteristics of low cost, simple process operation and the like; has a refractive index of 1.40 to 1.43, is a colorless transparent gel, has a light transmittance of more than 92%, has a certain elasticity and resilience, can resist external shocks, and can keep permanent adhesiveness; and can be completely cured at room temperature or heating temperature, thereby having good economy and reliability. 
         [0043]    2. The adhesion promoter of the present invention is an interface reinforcing agent with excellent properties, which can improve the adhesion capability between the silicone gel and the surface to be adhered.
