Description

一种可降解塑料
技术领域
发明涉及一种可降解塑料。
背景技术
塑料是一种普遍而耐用的材料，但是塑料造成的污染也很可怕，白色污染对环境造成了不可逆转的伤害，因此现在可降解塑料制品一直是目前研发的热点，各种新产品层出不穷，最早是光敏降解材料，新近的研发热点为淀粉基降解塑料，即生物降解塑料，但是现今的可降解塑料未必可以做到完全降解，生物降解塑料在干旱或缺乏土壤等一些特殊区域难以降解，而光降解塑料被掩埋在土中时也不能形成降解，而且现在制作可降解塑料使用的可降解高分子材料为聚己内酯（PCL），聚乳酸（PLA），聚丁二酸丁二醇酯（PBS），价格较昂贵，如何能够利用现有的材料，尤其是废弃材料，生产一种可降解塑料，则可以大大降低成本，还能减少对环境的污染。
发明内容
本发明的目的是提供一种稳定性强，力学性能好的磁性塑料材料。
本发明是通过以下技术方案来实现的：
一种可降解塑料，由以下重量份的组分构成：合成树脂40-80份；改性淀粉50-70份；光敏剂1-8份；助剂5-20份。
所述合成树脂为PP树脂。
所述助剂包括增塑剂、润滑剂、热稳定剂，所述增塑剂选用柠檬酸三丁酯、矿物油、乙酸三丁酯、尿素、甲酰胺中的任一种，所述润滑剂为硬脂酸镁，所述热稳定剂为亚磷酸三苯酯。
本发明的有益效果是：本发明具有优异的降解性能，对环境适应性强，而且质地轻，易加工，可广泛用于电子、光电、通信、生活等领域。
