Description

一种双层塑料管材
技术领域
本发明涉及一种双层塑料管材，尤其涉及一种具有多性能的双层塑料管材。
背景技术
随着科技水平的不断发展，塑料管材应用也越来越广，已应用到多个领域，塑料管材以其质量轻、阻燃、耐酸、加工便捷、耐用等性能特点逐渐替代了金属管材，尤其是其耐用性能特点最为重要，在日常生活中用到的塑料管材比较多，不少塑料管材的质量性能都没达到要求，尤其受环境因素的影响对塑料管材的要求更为严格，如抗老化、强度等性能方面更需要严格把关，以防止出现故障，影响人们的日常生活。
发明内容
本发明所要解决的技术问题在于：提供一种双层塑料管材，所述双层塑料管材具有抗老化、强度高等性能。
为解决上述问题，本发明的技术方案是一种双层塑料管材，包括内层和外层，所述内层与所述外层共挤成一体式结构，所述内层由聚丙烯85～90%、3～5%聚乙烯、1～3%POE、2～3%乙丁橡胶、4～6%复合稳定剂组成，所述外层由90～93%聚丙烯、1～3%碳黑、2～3%钛白粉、3～5%光稳定剂组成。
进一步地，所述聚乙烯是增强聚乙烯。
进一步地，所述增强聚乙烯是在中加入增强剂、稳定剂、偶联剂采用经偶联剂处理的玻璃纤维改性而成的。
进一步地，所述复合稳定剂为硬脂酸钙与硬脂酸锌的混合体。
进一步地，所述光稳定剂是二苯甲酮类光稳定剂。
与现有技术相比，本发明的有益效果如下：采用双层共挤一体系结构，增加了管材的整体厚度和强度，在外层中添加有炭黑、光稳定剂用于防止管材老化，在内层中添加增强聚乙烯用于增强管材的整体性能。
