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。A Polyacrylate emulsion with reactive ketonic groups was prepared through emulsion copolymeri- zation of styrene, butyl acrylate, acrylic acid and diacetone acrylamide. Based on the ambient curing reaction between the emulsion and adpic dihydrazide as the crosslinker, a series of coatings were prepared. The influence of ratio of functional groups on gel content, mechanical properties and water resistance was discussed.
