摘要:

本文研究了自制的CPPgGMA(氯化聚丙烯接枝甲基丙烯酸缩水甘油酯)对聚丙烯的粘接作用,并以CPPgGMA为底漆、双组分丙烯酸清漆为面漆对聚丙烯及其复合材料进行了涂装,探讨了CPPgGMA对涂层附着力的影响及其与接枝率的关系。结果表明,GMA的接枝可在一定程度上改善CPP与聚丙烯的粘接作用,能有效提高聚丙烯及其复合材料与丙烯酸漆的附着力,随着接枝率的增加,提高的幅度增大,在接枝率为2.31%时附着力等级可达到最高的0级。

Abstract:

In this paper,polypropylene (PP) bonding with CPPgGMA (glycidyl methacrylate grafted chlorinated polypropylene) was studied as well as bicomponent acrylic coating painted on PP and its composite after using CPPgGMA as a primer.The results show that the adhesive strength of CPPgGMA to PP is better to some extent than that of CPP to PP,and the adhesion strength of coatingsubstrate can be improved effectively.As the grafting degree of glycidyl methacrylate onto chlorinated increasing,the adhesion strength of coatingsubstrate increased more and more significantly.When using CPPgGMA with grafting degree of 2.31% as primer the coating adhesion can even reach class zero which is the best class.
