Description

耐磨EVA发泡鞋底及其加工工艺
技术领域
本发明涉及EVA发泡鞋底材料技术领域,具体涉及一种耐磨EVA发泡鞋底及其加工工艺。
背景技术
乙烯-醋酸乙烯共聚物,简称EVA。一般醋酸乙烯(VA)的含量在5%~40%,与聚乙烯(PE)相比,EVA由于在分子链中引入醋酸乙烯单体,从而降低了高结晶度,提高了韧性、抗冲击性、填料相溶性和热密封性能,被广泛用于发泡鞋材、功能性棚膜、包装模、热熔胶、电线电缆及玩具等领域。
鞋材是我国EVA树脂最主要的应用领域。由于EVA树脂共混发泡制品具有柔软、弹性好、耐化学腐蚀等性能,因此被广泛应用于中高档旅游鞋、登山鞋、拖鞋、凉鞋的鞋底和内饰材料中。另外,这种材料还用于隔音板、体操垫和密封材领域。
但是,目前所使用的EVA发泡鞋底材料还存在以下问题:
1、作为橡胶鞋底性能较差,特别是在耐磨性能差;
2、经发泡后,拉伸强度大幅降低,导致力学性能差,无法兼具良好的耐磨性能和力学性能以及轻便性,综合使用性能差。
