Description

一种可发泡聚乙烯材料
技术领域
本发明涉及高分子材料技术领域，特别涉及一种可发泡聚乙烯材料。
背景技术
聚乙烯（polyethylene ，简称PE）是乙烯经聚合制得的一种热塑性树脂。在工业上，也包括乙烯与少量α-烯烃的共聚物。聚乙烯无臭，无毒，手感似蜡，具有优良的耐低温性能（最低使用温度可达-100~-70°C），化学稳定性好，能耐大多数酸碱的侵蚀（不耐具有氧化性质的酸）。常温下不溶于一般溶剂，吸水性小，电绝缘性优良。
目前市场上主要的大宗发泡材料有聚氨酯发泡，物理发泡聚乙烯、聚苯乙烯和聚丙烯等。中国发明专利CN102924777A提供了一种高压聚乙烯发泡材料及其连续发泡工艺，系高压聚乙烯、AC发泡母料和DCP架桥剂用混料机混合好，与挤出机中挤出后压光，然后送入发泡机交联发泡，发泡后的材料经冷却辊冷却定型后，卷取包装。该法得到的发泡材料弹性好，属于软性泡体，硬度不够，且该法不适合于各种制品模具发泡成型。中国发明专利CN102558647A提供了一种高性能发泡聚乙烯制品的制备方法。该发泡聚乙烯为物理发泡，系使用聚乙烯、过氧化物、滑石粉和碳酸钙以及丁烷物理发泡剂，通过挤出机机头压力释放发泡而成发泡制品，该法不适合于各种制品模具发泡成型。
发明内容
本发明的目的在于提供一种可发泡聚乙烯材料，可以在无压力模具中受热发泡成型，因而可适用于各种形状产品的发泡空间制备。
本发明解决其技术问题所采用的技术方案是：

本发明的可发泡聚乙烯材料，先利用塑胶生产设备制成可发泡聚乙烯粒子，然后该塑胶粒子可以加入各种形状产品的模具中，受热后发泡成型。发泡后的泡体，不仅发泡程度高，并且由于聚乙烯分子链上引进了MBS和/或ABS，泡体硬度高，具有优异的缓冲减震功用，不仅可用于建材、包装、轻工等领域，更可用于军工、海工对缓冲抗震、装备轻量化和特殊形状产品功能化的要求。
作为优选，所述不饱和聚合物为MBS树脂、ABS树脂中一种或两种。
甲基丙烯酸甲酯-丁二烯-苯乙烯共聚物 ， 丙烯腈-丁二烯-苯乙烯共聚物
作为优选，所述自由基引发剂为偶氮二异丁腈（AIBN）、过氧化二异丙苯（DCP）、过氧化苯甲酰（BPO）、1,3-双（叔丁基过氧基异丙基）苯（BIBP）中的一种或几种。
作为优选，所述发泡剂为N,N-二亚硝基五亚甲基四胺、4,4ˊ-氧化二苯磺酰肼、偶氮二甲酰胺、碳酸氢铵中的一种或几种。
作为优选，所述润滑剂为PE蜡、硬脂酸、硬脂酸锌中的一种或几种。
作为优选，所述无机填料为碳酸钙、滑石粉、高龄土中的一种或几种。
作为优选，所述抗氧剂为4,4'-硫代双(6-叔丁基-3-甲基苯酚)、抗氧剂1010中的一种或几种。
作为优选，将各组分按配比加入密炼机中混炼，混炼好的物料通过单螺杆挤出机挤出造粒，即得可发泡聚乙烯材料。
作为优选，混炼温度控制在130-150℃，混炼时间控制在5-6min。
作为优选，单螺杆挤出机加工温度区间设置为130-150℃。
本发明的有益效果是：
（1）采用了PE与MBS和/或ABS刚性的高分子在线接枝化学反应，从而制备出的泡体具有很高的硬度，表面硬度可达邵氏D60度。
（2）通过在线熔融接枝MBS和/或ABS到聚乙烯大分子链上，形成高熔体强度的高分子材料，从而可以得到更高的发泡倍率，本发明一种可发泡聚乙烯材料的发泡密度接近聚氨酯的发泡密度，密度可达0.04g/cm3。
（3）本发明一种可发泡聚乙烯材料，可以在无压力模具中受热发泡成型，因而可适用于各种形状产品的发泡空间制备。
