一种水性双组份面漆及其制备方法
摘要：
本发明公开了一种水性双组份面漆及其制备方法。该水性双组份面漆由A、B两组分以(2.5～3.5)：1的质量比混合得到，其中A组分包含按照重量份的以下成分：水性丙烯酸树脂25～40份、水性聚酯树脂25～40份、色浆10～30份、基材润湿剂0.1～1份、流平剂0.1～1份、消泡剂0.1～1份、紫外线吸收剂0.1～1份、杀菌剂0.1～1份、助溶剂5～10份、增稠剂0.1～1份、羧甲基壳聚糖2～5份；B组分包含按照重量份的以下成分：异氰酸酯固化剂40～60份、附着力促进剂0.1～1份、助溶剂40～60份。该面漆的饱满度、光泽、流平性、施工性和力学方面性能可以达到高性能油性面漆的标准，高于现有常规水性面漆，并且具有低VOCs优点。
摘要（英）：

The invention discloses a waterborne two-component finishing coat and a preparation method thereof. The waterborne two-component finishing coat is prepared by mixing a component A and a component B inmass ratio of (2.5-3.5):1, wherein the component A consists of the following components in parts by weight: 25-40 parts of waterborne acrylic resin, 25-40 parts of waterborne polyester resin, 10-30 parts of mill base, 0.1-1 part of substrate wetting agent, 0.1-1 part of flatting agent, 0.1-1 part of defoamer, 0.1-1 part of ultraviolet light absorber, 0.1-1 part of bactericide, 5-10 parts of cosolvents, 0.1-1 part of thickener and 2-5 parts of carboxymethyl chitosan; the component B consists of the following components in parts by weight: 40-60 parts of isocyanate curing agent, 0.1-1 part of adhesion promoter and 40-60 parts of cosolvents. The saturation, glossiness, leveling properties, constructability and dynamics of the finishing coat can reach the standard of high-performance oil finishing coat and are better than that of the prior conventional waterborne finishing coat, and the finishing coat has the advantage of low VOCs (volatile organic chemicals).
