一种弹性防水密封胶、其制备方法及其形成的屋面防水结构
摘要：
本发明公开一种弹性防水密封胶，包括α-二甲氧基硅烷封端聚醚树脂15～25份；γ-三甲氧基硅烷封端聚醚树脂20～30份；对苯二甲酸二辛酯5～10份；纳米碳酸钙40～55份；气相二氧化硅0.1～5份；钛白粉0.5～5份；炭黑0.1～1份；紫外线吸收剂0.1～0.5份；光稳定剂0.1～0.5份；脱水剂0.5～1份；附着力促进剂0.5～1份；本发明还公开了一种弹性防水密封胶的制备方法及密封胶形成的屋面防水结构。有益效果是：该弹性防水密封胶对人体无害；由该弹性防水密封胶形成的屋面防水结构能够形成完全闭合的防水层，施工简单，防水效果优异。
摘要（英）：

The invention discloses an elastic waterproof sealant comprising 15-25 parts of alpha-dimethoxysilane-terminated polyether resin, 20-30 parts of gamma-trimethoxysilane-terminated polyether resin, 5-10 parts of dioctyl terephthalate, 40-55 parts of nano-calcium carbonate, 0.1-5 parts of fumed silica, 0.5-5 parts of titanium dioxide, 0.1-1 part of carbon black, 0.1-0.5 parts of an ultraviolet absorber, 0.1-0.5 parts of a light stabilizer, 0.5-1 parts of a dehydrating agent, 0.5-1 parts of an adhesion promoter. The invention also discloses a preparation method of the elastic waterproof sealant, and a roof waterproof structure formed by the elastic waterproof sealant. The elastic waterproof sealant has the advantages that: the elastic waterproof sealant is harmless to human; a roof waterproof structure formed by the elastic waterproof sealant can form a completely closed waterproof layer; construction is simple, and waterproof effect is excellent.
