在甲苯溶液中将乙烯/醋酸乙烯共聚物(EVA)料粒、甲基丙烯酸甲酯(MMA)和丙烯酸(AA)进行三元接枝共聚制备中间体,然后按一定配比将中间体与混合溶剂、功能助剂和荧光增白剂等进行混配,制成一种效果良好的EVA处理剂。该处理剂与国外同类产品相比,完全满足EVA与聚氯乙烯(PVC)、橡胶、热塑性弹性体(TPR)、真皮和聚氨酯(PU)仿皮等材料的粘接性能要求,各项性能指标均不低于国外同类产品。
In the toluene solution ethylene / vinyl acetate copolymer (EVA) particles, methyl methacrylate (MMA) and acrylic acid (AA) ternary graft copolymer intermediate preparation, and then in a certain ratio of the intermediate and mixing Solvent, functional additives and optical brighteners, etc., to make a good effect of EVA treatment agent. Compared with similar foreign products, the treatment agent fully meets the adhesive performance requirements of EVA and polyvinyl chloride (PVC), rubber, thermoplastic elastomer (TPR), leather and polyurethane (PU) leather, etc. The performance indexes Are not lower than similar foreign products.
