【技术实现步骤摘要】
一种双层塑料管材
本技术涉及塑料管材
,更具体地说是一种双层塑料管材。
技术介绍
塑料管材具有密封性好、价格便宜等优点,常用作建筑排水专用管材。然而,传统的塑料管材抗摔性较差,在仓储、运输及安装过程中,一旦管材摔落或抛落在工地地面时,在巨大的冲击力作用下容易在管材内外壁产生人体肉眼难以识别的细小裂纹,而在通水加压后,细小裂纹会逐步增大,导致管材漏水,从而使得整条管材报废,造成漏水的严重后果。
技术实现思路
为了克服以上现有技术的不足,本技术提供一种具有良好抗摔性的双层塑料管材。为解决现有技术问题,本技术采用的技术方案是:一种双层塑料管材,包括内层塑料管和外层塑料管,内层塑料管与外层塑料管挤压成一体,所述内层塑料管为聚丙烯塑料管,所述外层塑料管为聚乙烯塑料管。进一步的,所述外层塑料管为高密度聚乙烯、低密度聚乙烯或线性低密度聚乙烯塑料管。进一步的,所述内层塑料管的管壁与外层塑料管的管壁的厚度比为1:2;所述内层塑料管的内径与外层塑料管的外径的长度比为1:2。进一步的,所述内层塑料管的壁厚大于等于8mm。进一步的,所述内层塑料管的内径大于等于15mm。所述外层塑料管中添加 ...
