Description
技术领域
本发明属于高分子泡沫材料领域，具体涉及抗静电/阻燃车用XPE环保发泡材料及其制备方法。
背景技术
XPE即化学交联聚乙烯发泡材料，是用低密度聚乙烯树脂加交联剂和发泡剂经过高温连续发泡而成，与EPE（物理发泡聚乙烯，俗称珍珠棉）相比，抗拉强度更高，泡孔更细。XPE是汽车、空调保温的理想材料，近年在体育休闲用品市场上发展迅速，如冲浪板、防潮垫、瑜伽垫等。在建筑上也有一定的用途，在阻燃材料上有更广泛的应用。近来在汽车、包装行业应用广泛。
XPE是非交联闭孔结构，又称化学交联PE,是一种新型环保的包装材料。它由低密度聚乙烯脂经物理发泡产生无数的独立气泡构成。但目前XPE发泡材料用于车饰领域，如遇高温，因不阻燃易融化甚至燃烧，找会造成严重损失，因此，市场急需同时具有抗静电和阻燃性能的XPE环保发泡材料。
发明内容
本发明的目的在于提供一种抗静电/阻燃车用XPE环保发泡材料及制备方法，提供一种安全、无毒、无味、节能环保的发泡材料。
为实现上述目的，本发明采用如下技术方案：
抗静电/阻燃车用XPE环保发泡材料，主要由下述重量份的原料制备而成：PE树脂60～80份，抗静电剂4～8份，自制复合阻燃剂20～30份，发泡剂5～20份，交联剂2～5份，发泡助剂3～5份。
优选的，主要由下述重量份的原料制备而成：PE树脂70份，抗静电剂6份，自制复合阻燃剂25份，发泡剂15份，交联剂4份,发泡助剂4份。
自制复合阻燃剂为：十溴二苯乙烷、三氧化二俤、氢氧化铝，其重量比为1:1:2。
抗静电剂为导电炭黑。
发泡剂为AC发泡剂。
交联剂为过氧化二异丙苯。
发泡助剂为氧化锌或者硬脂酸锌。
抗静电/阻燃车用XPE环保发泡材料的制备方法，所述方法包括如下：
（1）将原料混合加入单螺杆挤出机中挤出XPE母片；
（2）接着放入三辊压光机对XPE母片进行光洁处理；
（3）再将其放入发泡炉进行连续常压发泡；
（4）对发泡后的XPE发泡片材于冷却定形架进行冷却定形；
（5）对定形后的XPE发泡片材于裁切机进行裁切，及对裁切后的XPE发泡片材于收卷机进行卷取。
发泡炉的条件为：温度180～230度。
本发明的优点在于：XPE具有隔水防潮、防震、隔音、保温、可塑性能佳、韧性强、循环再造、环保、抗撞力强等诸多优点，亦具有很好的抗化学性能，克服了普通发泡胶易碎、变形、回复性差的缺点是传统包装材料的理想替代品。本发明把抗静电、阻燃性能融入到XPE发泡材料中，配方简单科学，产品既具有抗静电性能又具有阻燃性能，化学物理性能稳定，彻底消除静电感应和易燃性，是一种安全、无毒、无味、节能环保的发泡材料。
