Description
技术领域
本发明涉及塑料材料领域，具体涉及一种抗腐蚀阻燃环保的高硬度塑料。
背景技术
塑料管种类很多，分为热塑性塑料管和热固性塑料管两大类。属于热塑性的有聚氯乙烯管，聚乙烯管，聚丙烯管、聚甲醛管等；属于热固性的有酚塑料管等。塑料管的主要优点是耐蚀性能好、质量轻、成型方便、加工容易、缺点是强度较低，耐热性差。塑料的弹性模量介于橡胶和纤维之间，受力能发生一定形变。软塑料接近橡胶，硬塑料接近纤维。狭义的塑料定义是指以树脂（或在加工过程中用单体直接聚合）为主要成分，以增塑剂、填充剂、润滑剂、着色剂等添加剂为辅助成分，在加工过程中能流动成型的材料。塑料为合成的高分子化合物，可以自由改变形体样式。塑料是利用单体原料以合成或缩合反应聚合而成的材料。
有机磷系阻燃剂是一种阻燃性能较好的阻燃剂，它具有阻燃增塑双重功能，可代替卤化系阻燃剂，使阻燃完全实现无卤化，但其对聚合物的物理机械性能影响较大。能改善聚合物基体的力学性能、气体阻隔性能和耐溶剂性能。
随着人们对环保以及对材料性能要求的提高，对于塑料材料要求具有良好的耐电绝缘性和安全环保性能，其耐热性、耐老化、阻燃性的指标要求也在提高，开发研制新型有效的、环境友好的阻燃耐磨舒适制塑料材料具有重要的意义。
尼龙66是聚酰胺树脂的熔点较高，具有很好的物理力学性能和耐老化性、耐磨性以及自润滑性，但是由于自身存在吸水率较高，可以长期吸收空气中的水分，从而导致物性变化，尤其是在长期持续高温高湿度的环境中，这个缺点已经变得无法接受了，必须得到大幅度改善。从合成树脂、塑料机械和塑料制品生产来看，中国塑料工业强劲的发展势头，现有的塑料管一般为单纯的塑料管，其强度比较低，而且这种塑料管在特定的条件下膨胀系数大、管道易软化和易变形，不易广泛应用。
发明内容
本发明的目的在于提供一种抗腐蚀阻燃环保的高硬度塑料。
本发明采取的技术方案为：
一种抗腐蚀阻燃环保的高硬度塑料，分为内外两层，其特征在于，原料按照重量份组成如下：
