本发明涉及塑料型材技术领域,具体涉及一种自增强异型材及其制备方法和应用。
衣柜,橱柜,办公桌的主体板材使用三聚氰胺板,密度板或刨花板,但由于不同型号产品的尺寸不一样,在制作过程中都需要按照不同尺寸把主体板材锯开,那么锯开的部分就是裸露的板芯,严重影响产品的外观,所以就需要包边材料把裸露的板芯部分包住,包边的好坏也是衡量衣柜质量的一个重要标准。另外,包边材料还对柜体的变形起着重要的作用,所以衣柜的包边材料还需要一定的强度,刚性等要求。

表1增强苯乙烯基合金组合物各组分配比(重量份)及物性
从表1可以看出,本发明的增强苯乙烯基合金组合物材料作为芯层,具有优异的强度、刚性等力学性能,且密度较低,只有铝合金材料的一半左右。
自增强异型材的制备:
采用主机与该主机垂直设计的辅机进行共挤制备,按表2配比,主机用于挤出增强苯乙烯基合金组合物材料,辅机用于挤出热塑性树脂型材,主机、辅机同时挤出,成型后冷却定型得到自增强异型材;
