该树脂是以乙烯基三甲氧基硅烷和六甲基二硅氮烷共改性气相二氧化硅为Pickering乳化剂,进行乙烯基硅油和含氢硅油分别乳化,得到相应的乳液,再混合制备而成。该树脂与Karstedt催化剂胶囊水分散液简单混合,制备了单组份水性可交联聚硅氧烷涂布液。该涂布液在室温下干燥后能交联形成弹性薄膜。
Fumed silica was co-modified with vinyltrimethoxysilane (VTMS) and hexamethyl disily-lamine (HMDS) and was further adopted to emulsify vinyl or hydrogen dimethicone. The as-obtained Pickering emulsions were mixed with Karstedt catalyst capsules to produce one-component waterborne cross-linkable polydimethylsiloxane (PDMS) coatings that were subsequently transformed into elastic films after drying at ambient temperature.
