Fastener base plate and preparation method thereof
The invention provides a fastener base plate and a preparation method thereof.The fastener base plate comprises a polyethylene plate and a rubber layer, the polyethylene plate is connected with the rubber layer, a grafting layer is arranged on the side, facing the rubber layer, of the polyethylene plate, the rubber layer comprises chitosan microspheres, and the chitosan microspheres are evenly dispersed in the rubber layer. The grafting layer is respectively connected with the rubber layer and the chitosan microspheres on the surface layer of the rubber layer; the polyethylene plate can be in vulcanization connection with the rubber layer through the grafting layer, Van der Waals acting force can also be generated between the polyethylene plate and the chitosan microspheres on the surface layer of the rubber layer, and the bonding strength between the polyethylene plate and the rubber layer can be effectively improved. Meanwhile, the chitosan plays a role in inhibiting and sterilizing bacteria in the rubber layer and between the rubber layer and the polyethylene plate, on one hand, the decomposition of bacteria on the rubber layer is inhibited, the aging of the rubber is delayed, and on the other hand, the good bonding strength between the polyethylene plate and the rubber layer is maintained for a long time.
本发明提供了一种扣件垫板及其制备方法，所述扣件垫板包括聚乙烯板、橡胶层，聚乙烯板与橡胶层连接，聚乙烯板朝向橡胶层的一侧设置接枝层，橡胶层包括壳聚糖微球，壳聚糖微球均匀分散在橡胶层，接枝层分别与橡胶层、橡胶层表层的壳聚糖微球连接；本发明使得聚乙烯板通过接枝层不仅能够与橡胶层硫化连接，也能够与橡胶层表层的壳聚糖微球之间产生范德华作用力，能够有效提高聚乙烯板、橡胶层之间的粘接强度。同时，壳聚糖在橡胶层内部、以及橡胶层与聚乙烯板之间起到抑菌、杀菌作用，一方面抑制细菌对橡胶层的腐融分解，有利于延缓橡胶的老化，另一方面有利于在较长时间内维持聚乙烯板、橡胶层之间具有良好的粘接强度。
