摘　　要：水性双组分聚氨酯(WB 2K-PU)涂料是环保领域突起的一门新技术,它具有高性能、低VOC含量的特点。随着多元醇树脂和异氰酸酯固化剂的发展,水性双组分聚氨酯涂料在汽车涂装应用中日益增多,且具有优异的涂膜性能。本文介绍了2K-PU涂料中树脂、助剂的选择,并制备了高性能水性双组分聚氨酯汽车涂料。In the field of environmentally friendly coatings the waterborne two - component polyurethane （WB 2K PU）systems represent a new technology, which combines the good film properties of solventborne 2K polyurethane coatings and the low VOC values of waterborne technology. Recently, with development of polyols and isocyanates, WB 2K PU coatings have been used increasingly as a high performance automotive clearcoats, which combines good chemical resistance and excellent appearance. In this paper, selection of resins and additives, and preparation of WB 2K PU coatings were described.
