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。
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 glyeidyl 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.
