摘　　要：评述了高性能水性涂料研究所取得的重大进展 ,涉及采用可聚合或大分子乳化剂及水溶性单体共聚的高固含量无皂乳液聚合技术 ,基于Michael加成反应、活泼羰基与酰肼基反应以及乙酰乙酰基与多元胺反应的交联等室温交联方法 ,紫外光固化以及水性树脂的混合技术等关键技术。指出水性涂料代表着低污染涂料发展的主要方向 ,目前面临的难题是在可接受的成本前提下如何提高产品的性能 ,使之达到与溶剂型涂料相同或接近的水平 ,并进一步降低有机挥发物的排放量。Great progress has been made in waterborne coatings.The research results at home and abroad show that the soap-free polymerization for emulsions with high solid contents with polymerizabe or macromolecular emulsifiers and copolymerizing with water-soluble monomers,the crosslinking of waterborne coatings under ambient temperature through the Michael addition reaction,the reaction of acetoacetoxy groups with polyamines and carbonyl groups with hydrazide,UV-radiation curing and waterborne-resin blend will become key techniques for developing waterborne coatings of high performance.Waterborne coatings represent a major direction for developing more environmentally friendly ones,for which the challenge is to obtain comparable performance with solvent-borne coatings,with little or no solvent emission,and at a reasonable cost.
