Description
技术领域
本发明涉及发泡材料技术领域,尤其涉及一种EVA发泡材料及其制备方法。
背景技术
目前市场上已有的鞋材的主要成份PVC(聚氯乙烯)、PE(聚乙烯)、PP(聚丙稀)、EVA(乙烯-乙酸乙烯共聚物)、橡胶等均为石油化工产品,它们均属高聚物,因聚合度较大,分子间作用力强,高分子链难以断裂分解,从而导致已有的鞋材具有不可降解性,这些聚合物材料大部分都来源于石油基,不仅消耗了大量的有限的石化资源,而且在自然界中短时间内无法分解,被丢弃后成为了“白色垃圾”或者被焚烧造成了空气污染,对环境是个潜在的威胁。同时,EVA发泡材料的发泡体系主要采用甲酰胺发泡体系,然而甲酰胺类发泡剂在发泡分解过程中会产生氨气、甲酰胺等具有刺激性气味的气体,这就使得制得的EVA发泡材料会存在刺鼻难闻异味,易对人体健康产生一定程度的危害。
基于上述情况,本发明提出了一种EVA发泡材料及其制备方法,可有效解决以上问题。
发明内容
本发明的目的在于提供一种EVA发泡材料及其制备方法。
为实现上述目的,本发明提供了一种EVA发泡材料,所述EVA发泡材料由EVA树脂、POE树脂、聚乙烯、滑石粉、硬脂酸锌、交联剂、发泡剂、苯乙烯共聚物组成。
优选地,所述聚乙烯为马来酸酐接枝聚乙烯。
优选地,所述交联剂为1,4-双叔丁基过氧异丙基苯。
优选地,所述发泡剂为4,4-氧代双苯磺酰肼与高岭土的组合物。
优选地,所述苯乙烯嵌段共聚物为聚苯乙烯-乙烯-丁烯-苯乙烯嵌段共聚物(SEBS)。
优选地,所述EVA发泡材料由以下重量份的原料组成:EVA树脂40~50份、POE树脂10~20份、马来酸酐接枝聚乙烯5~10份、滑石粉20~30份、硬脂酸锌1~3份、1,4-双叔丁基过氧异丙基苯1~1.5份、4,4-氧代双苯磺酰肼0.4~1.2份、高岭土1~1.5份、聚苯乙烯-乙烯-丁烯-苯乙烯嵌段共聚物(SEBS)10~15份。
在其中一个实施例中,所述EVA发泡材料由以下重量份的原料组成:EVA树脂40份、POE树脂10份、马来酸酐接枝聚乙烯5份、滑石粉20份、硬脂酸锌1份、1,4-双叔丁基过氧异丙基苯1份、4,4-氧代双苯磺酰肼0.4份、高岭土1份、聚苯乙烯-乙烯-丁烯-苯乙烯嵌段共聚物(SEBS)10份。
在其中一个实施例中,所述EVA发泡材料由以下重量份的原料组成:EVA树脂50份、POE树脂20份、马来酸酐接枝聚乙烯10份、滑石粉30份、硬脂酸锌3份、1,4-双叔丁基过氧异丙基苯1.5份、4,4-氧代双苯磺酰肼1.2份、高岭土1.5份、聚苯乙烯-乙烯-丁烯-苯乙烯嵌段共聚物(SEBS)15份。
在其中一个实施例中,所述EVA发泡材料由以下重量份的原料组成:EVA树脂45份、POE树脂15份、马来酸酐接枝聚乙烯8份、滑石粉25份、硬脂酸锌2份、1,4-双叔丁基过氧异丙基苯1.2份、4,4-氧代双苯磺酰肼0.8份、高岭土1.2份、聚苯乙烯-乙烯-丁烯-苯乙烯嵌段共聚物(SEBS)12份。
本发明申请还提供一种EVA发泡材料的制备方法,所述方法包括如下步骤:
(1)将EVA树脂、POE树脂、马来酸酐接枝聚乙烯、滑石粉、硬脂酸锌、聚苯乙烯-乙烯-丁烯-苯乙烯嵌段共聚物,倒入密炼机中进行密炼,密炼温度控制在130~135℃,时间为10~15min;
(2)将1,4-双叔丁基过氧异丙基苯、4,4-氧代双苯磺酰肼、高岭土加入到步骤(1)中,继续进行密炼,密炼温度控制在160~175℃,时间约为5~10min分钟;

1.本发明使用1,4-双叔丁基过氧异丙基苯作为交联剂以及4,4-氧代双苯磺酰肼与高岭土的组合物作为发泡剂,能有效减少发泡材料中挥发性有机化合物的释放,绿色环保,降低了刺激性气味对人体健康产生危害的可能性。
2.本发明通过加入马来酸酐接枝聚乙烯以及聚苯乙烯-乙烯-丁烯-苯乙烯嵌段共聚物(SEBS),从而提高了发泡材料的拉伸强度、回弹率等力学性能,有利于将其进一步进行加工。
3.本发明原材料在国内充足,价格适宜,使其规模化生产没有太高的成本限制;同时,制备方法简单,总体生产成本不高,有利于工业的大规模生产。
