Organosilicon section sealant and preparation method thereof

The invention discloses an organic silicon section sealant and a preparation method thereof. The organic silicon section sealant provided by the invention is prepared from 90 to 110 parts by weight of alpha, omega-dihydroxy polysiloxane, 10 to 20 parts by weight of dimethyl silicone oil, 5 to 10 parts by weight of fumed silica, 6 to 15 parts by weight of a ketoxime cross-linking agent, 5 to 15 parts by weight of a titanate tackifier, 1 to 2 parts by weight of a silane coupling agent and 0.5 to 1 part by weight of a catalyst. The organic silicon section sealant is extremely easy to form, can fill tiny slits and irregular shapes on the surface of an object, is high in plasticity, is high in adhesive force to various base materials, does not have a cracking phenomenon, is wide in application range, and is excellent in temperature resistance and corrosion resistance. 本发明公开了一种有机硅断面密封胶及其制备方法。本发明提供的有机硅断面密封胶由90-110重量份的α，ω-二羟基聚硅氧烷、10-20重量份的二甲基硅油、5-10重量份的气相二氧化硅、6-15重量份的酮肟交联剂、5-15重量份的钛酸酯增粘剂、1-2重量份的硅烷偶联剂和0.5-1重量份的催化剂制备而成
