Dealcoholized heat-conducting silicone rubber without corrosion to PC (polycarbonate) as well as preparation method and application thereof

The invention provides dealcoholized heat-conducting silicone rubber without corrosion to PC (polycarbonate) as well as a preparation method and application of the dealcoholized heat-conducting silicone rubber. The heat-conducting silicone rubber is prepared from the following components in parts by weight: 80 to 100 parts of alpha, omega-dihydroxy polydimethylsiloxane, 0 to 20 parts of dimethyl silicone oil, 700 to 1300 parts of heat-conducting filler, 3 to 5 parts of cross-linking agent, 0.1 to 1 part of tackifier and 0.1 to 0.5 part of catalyst. The heat-conducting silicone rubber can be used in heat-conducting sealants. According to the heat-conducting silicone rubber disclosed by the invention, on the premise of keeping relatively high heat conductivity and relatively good adhesive strength, the corrosion to a PC material is obviously reduced. 本发明提供了一种对PC无腐蚀的脱醇型导热硅橡胶及其制备方法和应用。该导热硅橡胶包含重量份的组分：α,ω-二羟基聚二甲基硅氧烷80-100份、二甲基硅油0-20份、导热填料700-1300份、交联剂3-5份，增粘剂0.1-1份，催化剂0.1-0.5份。本发明的导热硅橡胶可以用于导热密封胶中。本发明的导热硅橡胶在保持较高导热率和
