Abstract
一种大口径双壁波纹管,其各组分质量份数为:内层:HDPE100-120份、微米CaCO310-20份、纳米SiO25-10份、偶联剂5-10份、润滑剂5-10份、色母料0-5份;外层:HDPE100-120份;微米CaCO315-25份;纳米SiO22-6份;偶联剂5-10份;润滑剂5-10份;色母料0-5份。本发明的有益效果是:本发明将微米CaCO3与纳米SiO2作为制作双壁波纹管的填料,能有效提高其落锤冲击强度和环刚度,更可以在不影响双壁波纹管物理特性的情况下有效的减轻单位重量,由于微米CaCO3与纳米SiO2的市场售价远低于高密度聚乙烯,故可以在保证产品质量的前提下,有效的降低成本。
Description
技术领域
本发明涉及双壁波纹管制造领域,特别是一种大口径双壁波纹管。
背景技术
双壁波纹管是一种外壁成波纹状、内壁光滑的新型管材。目前已被广泛用作埋地排水管、地下电缆管等,在相当范围内以取代了传统的铸铁管、水泥管、普通塑料管、和缠绕波纹管。目前双壁波纹管主要的品种有聚氯乙烯(PVC)和高密度聚乙烯(HDPE)两种。而HDPE双壁波纹管又以其耐腐蚀性强、表面不易结垢、摩擦阻力小、耐候性优良、加工性能好及使用寿命长等特点而更为广泛应用。但是目前在使用过程中影响埋地用HDPE双壁波纹管特别是大口径HDPE双壁波纹管,由于双壁波纹管口径的增加,导致其环钢度降低,落锤冲击强度降低,无法满足工程需要。
环钢度低,落锤冲击强度低可以通过增加壁厚的方法来解决,但是波纹管壁厚的增加,会造成用料的增加,进而使生产成本增加;另外,也会使双壁波纹管的重量增加,对安装造成影响。
发明内容
本发明为解决上述技术问题,提供一种具有成本低、易于制作、配方简单且能提高大口径双壁波纹管对环刚度与落锤冲击强度要求的大口径双壁波纹管。本发明所称的大口径双壁波纹管是指直径大于500mm的双壁波纹管。采用的技术方案如下:
一种大口径双壁波纹管,其特征在于,所述一种大口径双壁波纹管制作材料及其质量份数为:
内层:
外层:
所述偶联剂为铝酸酯或钛酸酯或硬脂酸。
所述润滑剂为蜡类。
根据以上配方制作的一种大口径双壁波纹管的制作方法,包括以下步骤:
步骤1:按所述一种大口径双壁波纹管所用材料的质量份数配料;
步骤2:将配料加入高速混合机中充分混匀,再进入低速搅拌,然后经过传送和过筛后将物料进行预热,之后分别加入双壁波纹管的内、外层挤出机;
步骤3:在挤出机中进行塑化挤出,并模压成型为双壁波纹管;
步骤4:待模压成型后的双壁波纹管冷却定型后,进行定长切割。
本发明的有益效果是:本发明将微米CaCO3与纳米SiO2作为制作双壁波纹管的填料,能有效提高其落锤冲击强度和环刚度,更可以在不影响双壁波纹管物理特性的情况下有效的减轻单位重量,由于微米CaCO3与纳米SiO2的市场售价远低于高密度聚乙烯,故可以在保证产品质量的前提下,有效的降低成本。
