摘　　要：研究了一种聚丙烯酸酯乳液复合改性水性聚氨酯胶粘剂的方法,以及聚丙烯酸酯的玻璃化温度Tg、功能单体等改变对改性后的PUA复合乳液的粘接性能的影响。结果表明:聚丙烯酸酯乳液的分子结构不同对复合乳液的粘接性能影响很大,通过改变聚丙烯酸酯乳液的用量、Tg、羟基含量、羧基含量等可以得到综合性能更优的复合乳液。The method of a polyacrylate emulsion composite modification of waterborne polyurethane adhesive was studied,as well as polyacrylate glass transition temperature Tg,and functional monomer on the modified PUA composite emulsion adhesive properties.The results showed that polyacrylate emulsion with different molecular structures had great influence on the adhesive properties of composite emulsion,and by changing the polyacrylate emulsion dosage,Tg,content hydroxyl and,carboxyl of can obtained better comprehensive properties of composite emulsion.
