The invention discloses a special single-component polyurethane base layer waterproof coating for a waterproof structure of a metal roof, which is mainly prepared from the following components in parts by weight: 20 to 30 parts of polyether glycol, 10 to 15 parts of polyether triol, 4 to 10 parts of diisocyanate, 15 to 25 parts of plasticizer, 45 to 60 parts of filler, 1 to 2 parts of pigment, 0.2 to 0.5 part of antioxidant, 0.3 to 0.5 part of dispersing agent and 2 to 4 parts of thixotropic agent. 0.2 to 0.4 part of a catalyst and 0.2 to 0.3 part of an adhesion promoter. When in use, the base layer waterproof coating is coated on a waterproof structure base layer, and after the coating is hard dry, the weather-resistant water-based waterproof coating is coated on the base layer waterproof coating. The prepared single-component polyurethane base layer waterproof coating has a good bonding effect with a surface layer water-based coating through formula design, the surface layer of the single-component polyurethane base layer waterproof coating can form a riveted structure with the base layer water-based coating due to a fine and dense pit structure designed by a foam stabilizing process, and the bonding effect of two different types of water-based and oil-based waterproof coatings is greatly improved.
本发明公开了一种专用于金属屋面防水结构的单组分聚氨酯基层防水涂料，主要由20‑30份的聚醚二元醇，10‑15份的聚醚三元醇，4‑10份的二异氰酸酯，15‑25份的增塑剂，45‑60份的填料，1‑2份的颜料，0.2‑0.5份的抗氧剂，0.3份‑0.5份的分散剂，2‑4份的触变剂，0.2‑0.4份的催化剂，0.2‑0.3份的附着力促进剂制备而成。使用时将本基层防水涂料涂制在防水结构基层，待涂料实干后再上面涂制耐候性水性防水涂料。本发明制备的单组分聚氨酯基层防水涂料通过配方设计与面层水性涂料具有较好的粘接效果，其表层因稳泡工艺设计的细密的凹坑结构，可以与基层水性涂料形成铆合结构，大幅度提升水性与油性两种不同类型防水涂层的粘接效果。
