摘　　要：通过苯乙烯(St)、丙烯酸丁酯(BA)、丙烯酸(AA)及双丙酮丙烯酰胺(DAAM)的乳液共聚合,合成了含有活性酮基的聚丙烯酸酯乳液,通过乳液与交联剂己二酸二酰肼的室温固化反应,制备了系列涂层材料,研究了官能团配比对涂层的凝胶含量、力学性能及耐水性能的影响.Polyacrylate emulsion with reactive ketonic groups was prepared through emulsion copolymerization of styrene, butyl acrylate, acrylic acid and diacetone acrylamide. Based on the ambient curing reaction between the emulsion and hexanedionic dihydrazide as the crosslinker, a series of coatings were obtained. The influence of ratio of the functional groups on the gel content, mechanical properties and water resistance was investigated.
