Abstract

本发明公开了一种高耐候性PE离型膜的制备方法,包括两个步骤:先粉体制备,再热压成型。粉体制备是将玻璃微珠、玻璃纤维、纳米蒙脱土、人造石墨粉与聚乙烯粉体混合放入球磨罐中进行球磨。热压成型是将球磨好的混合粉末分别放入模具中在平板硫化机上,进行材料坯体的制备。完成后,将坯体从模具中取出。利用本方法制得的PE离型膜,剥离强度、耐候性、耐高温性、力学性能优越,相较于常规的离型膜而言,其应用范围更为广泛。

Description

一种高耐候性PE离型膜的制备方法
技术领域
本发明涉及一种离型膜,尤其是一种具有耐候性的PE离型膜。
背景技术
PE离型膜是当今世界应用最广泛的高分子材料,由乙烯聚合而成,聚乙烯不溶于水,吸水性很小,就是对一些化学溶剂,如[1]、醋酸等,也只有在70℃以上温度时才略有溶解。但是微粒状的聚乙烯,可以在15℃~40℃之间随温度的变化熔化或凝固,温度升高时熔化,吸收热量;温度降低时凝固,放出热量。又因为它吸水量很小,不易潮湿,有绝缘性能,因此是很好的生产、建筑材料。但是,由于其材料PP自身的性能,因此PE薄膜的耐候性较差,更容易在光、热、氧等外部环境的作用下发生老化,这就影响了其使用范围。
因此,为了经济的发展,有必要开发出一种具有良好耐候性的PE离型膜。
发明内容
本发明的目的在于提供一种高耐候性PE离型膜的制备方法,从而改善目前PE离型膜耐候性差、容易老化的问题。
本发明是通过以下技术方案来实现的:
该高耐候性PE离型膜通过粉体制备,热压成型制得。
(1)粉体制备包括以下步骤:
将玻璃微珠、玻璃纤维、纳米蒙脱土、人造石墨粉与聚乙烯粉体混合放入球磨罐中进行球磨,先以转速450-550r/min球磨10-15min,再以转速180-240r/min球磨10-15min,球料比:1,球磨40-80min。
进一步的,所述球磨为顺时针球磨方式。
进一步的,所述球料比为4-5:1。
(2)所述热压成型包括以下步骤:
将步骤(1)制备的混合粉末放入模具中,在平板硫化机进行材料胚体制备,温度为160-200℃,压力为12-15MPa,热压时间为15-25min,再放置室温冷压5-10min。
有益效果:
本发明通过加入玻璃微珠,提高了制品的阻燃性和热变型温度,而蒙脱土作为纳米聚合物高分子材料的添加剂被广泛应用于高分子材料行业,加入蒙脱土后能有效提高PE离型膜的抗疲劳性、抗冲击性,增强了产品的综合物理性能,同时改善物料加工性能。本发明的高耐候性PE离型膜,有效解决了目前PE离型膜加工难成型这一难题,其薄膜层材料所用组分环保无毒,其制备方法简单、容易操作、条件温和,更适用于工业化生产。
