摘要： 采用高速剪切制备复合硫化剂水分散体,乳液物理共混制备橡胶/织物复合用水基胶乳胶粘剂。研究了水乳胶粘剂中各组分的比例对粘接强度的影响,同时对胶粘剂的贮存稳定性、胶粘剂胶膜的力学性能和胶粘剂中各组分胶乳的相容性进行了探讨。结果表明:氯丁胶乳/天然橡胶胶乳/苯丙乳液/复合硫化剂水分散体/萜烯树脂乳液的比例(质量比)为5∶5∶1.5∶3∶1.5时,胶粘剂粘接效果最好,胶粘剂的T型剥离强度可以达到2.82 MPa(达到市售溶剂型胶粘剂粘接强度的85%)。

Abstract: A blended waterbased adhesive for rubber- textile concposite was prepared by blending of latex and curing agent dispersion with high-speed shearing machine. The effect of proportional amount of each compoment on adhesive bonding strength were studied, and the storage stability of the adhesive, mechanical properties of adhesive film and compatibility among components in adhesive were discussed. The results showed that when the ratio of neoprene latex/natural rubber latex/styrene-acrylic emulsion/curing agent dispersion/terpene resin emulsion is 5: 5: 1. 5: 3, the bonding strength was the highest, and the T-peel strength of adhesive can reach 2.82 MPa.
