摘　　要：采用水性氯丁与丙烯酸酯共混的方式,制备得到了速粘自干水性胶黏剂。详细考察了乳液的结晶性、玻璃化转变温度(T_(g))、丙烯酸酯乳液(AEL)/氯丁乳液(CRL)的配比对胶黏剂力学性能的影响。通过拉力测试、热重分析(TG)、耐热测试、T型剥离力测试等分析表明:当C84/C2694=8∶2、SL-390/C2694=8∶2、丙烯酸酯乳液的T_(g)在-50~-60℃之间、且AEL/CRL的质量比为40∶60时,乳液胶黏剂的综合性能最佳。A rapid cohesive water-based adhesive was prepared by combining acrylate emulsion(AEL)and chloroprene rubber latex(CRL).Effects of crystallinity,glass transition temperature(T_(g)),and mass ratio of AEL/CRL on mechanical properties of acrylate-neoprene composite emulsion were investigated.The results of tension test,thermogravimetric analysis(TG),heat-resistant capability analysis and stripping force test showed that the performance of composite emulsion was optimal when C84/C2694=8∶2,SL-390/C2694=8∶2,T_(g)of acrylate latex was from-50℃to-60℃,and AEL/CRL=40/60.
