【Abstract】 The additional two-component silicone gel was prepared by taking vinyl-containing polydimenthylsiloxane as basic components, hydrogen-containing silicone oil as cross-linking agent, platinum chloride coordination compound as catalyst, vinyl-containing MQ silicone resin as reinforced filler and epoxy group-containing siloxane as tackifier. The effects of molar mass of basic components, content of cross-linking agent, catalyst and tackifier on the performance of silicone gel were discussed. The preferable technical formula was that taking basic components with viscosity of 1200～1500 mPa·s, cross-linking agent 3.5 %～4.0 % according to mass of basic components, vinyl-containing MQ resin 6.0 %～8.0 %, tackifier 0.9% and platinum catalyst 60×10 -6 . It has transparent appearance, 3 to 6 hours curing time, exceed 100 penetration-graded.更多还原
