Description

抗静电可生物降解泡沫材料及其制备方法
技术领域
本发明涉及一种抗静电可生物降解泡沫材料及其制备方法，属于泡沫材料技术领域。
背景技术
不论是以聚乙烯、聚苯乙烯，还是以聚氨酯为原料制得的泡沫塑料都具有质轻、省料、热导率低、隔热性能好、吸收冲击载荷、隔音性能好、比强度高等性能，在包装行业发挥着巨大的作用。然而，这些泡沫塑料被使用后，很难回收处理再次循环使用，丢弃到环境中，不能与环境同化，对环境造成巨大危害。如漂浮在海洋中被海洋生物吞服，致使海洋生物死亡。因此，大力开发和推广可降解泡沫材料受到世界范围的学术界和工业界的关注。
聚对苯二甲酸-己二酸丁二醇酯是对苯二甲酸、己二酸和1，4-丁二醇的三元共聚酯,属完全生物降解塑料。由于聚对苯二甲酸-己二酸丁二醇酯中含柔性的脂肪链和刚性的芳香键,因而具有高韧性和耐高温性，将其制备成发泡材料后，可以有效解决传统发泡材料带来的污染问题。
但是将聚对苯二甲酸-己二酸丁二醇酯制成发泡材料后，由于材料本身具有良好的电绝缘性，使得发泡材料也具有良好的电绝缘性,在成型加工或使用时,因摩擦而带静电。静电往往能吸附尘埃,从而影响产品的表观质量,在一些特殊环境中使用时,甚至会因放电而招致爆炸或燃烧事故。近年来，随着我国电子行业的迅速发展，对于一些敏感的电子元件、芯片、仪器仪表等电子产品对包装材料的要求非常严格，如果采用了非抗静电包装材料，材料会因电磁感应和摩擦产生静电积累而进行高压放电，进而破坏包装内容物的电子产品，造成极大地经济损失。要获得较好的抗静电效果，往往要在聚合物中添加导电填料，或是添加抗静电剂，利用在高聚物中形成导电通道起到抗静电的作用。但是对于单一聚合物而言，要获得较好的抗静电效果，往往要添加很大比例的抗静电剂，引起材料力学性能下降。引入另一聚合物组分，由于两相界面的存在，抗静电剂可以优先分散在一相或是界面处，可以大大减少抗静电剂的用量，提高材料的力学性能。
