Anti-sagging quick-drying two-component polyurethane waterproof paint as well as preparation method and application thereof
The invention discloses an anti-sagging quick-drying two-component polyurethane waterproof paint, which comprises a component A and a component B. The weight ratio of the component A to the componentB is (1: 1)-(1: 2), and the component A is mainly prepared from polytetrahydrofuran ether glycol, aliphatic isocyanate, a plasticizer, a chain extender and a catalyst A; and the component B is mainlyprepared from ethylene diamine polyether, polyaspartate polyurea resin, a plasticizer, carbon black, a catalyst B, an inorganic filler, a thixotropic agent and other assistants. The preparation methodcomprises the following steps: carrying out vacuum dehydration on polytetrahydrofuran ether glycol, cooling, and adding other components to prepare the component A; uniformly dispersing ethylene diamine polyether and polyaspartic acid ester polyurea resin, adding other components, and grinding to obtain the component B; the waterproof paint is an aliphatic polyurethane waterproof paint, a concrete protective layer is not needed in waterproof layer construction, the waterproof paint can be directly exposed, meanwhile, a concrete protective layer is not needed, the sagging resistance value of the waterproof paint is 500 [mu]m or above, surface drying and hard drying are fast, and the product maintenance period is shortened.
一种抗流挂快干型双组份聚氨酯防水漆，包括重量比为(1：1)～(1：2)的A组份和B组份，A组份主要由聚四氢呋喃醚二醇、脂肪族异氰酸酯、增塑剂、扩链剂、催化剂A制备而成；B组份主要由乙二胺聚醚、聚天门冬氨酸酯聚脲树脂、增塑剂、炭黑、催化剂B、无机填料、触变剂和其他助剂制备而成。制备方法为：将聚四氢呋喃醚二醇真空脱水，降温，再加入其他组分制备成A组份；将乙二胺聚醚、聚天门冬氨酸酯聚脲树脂分散均匀，再加入其他成分，研磨，得到B组份。本发明的防水漆属脂肪族聚氨酯防水漆，防水层施工不需要混凝土保护层，可直接外露，同时不需要混凝土保护层，防水漆抗流挂性值在500um以上，表干实干快，产品养护周期缩短。
