Description

一种预应力混凝土用波纹管
技术领域
    本发明主要涉及一种管材，尤其涉及一种预应力混凝土用波纹管。
背景技术
PVC管（UPVC管） 硬聚氯乙烯管，是由聚氯乙烯树脂与稳定剂、润滑剂等配合后用热压法挤压成型，是最早得到开发应用的塑料管材。UPVC管抗腐蚀能力强、易于粘接、价格低、质地坚硬，但是由于有UPVC单体和添加剂渗出，只适用于输送温度不超过45℃的给水系统中。塑料管道用于输送饮用水，废水，化学品，加热液和冷却液，食品，超纯液体，泥浆，气体，压缩空气和真空系统的应用。
PE管有中密度聚乙烯管和高密度聚乙烯管。前者适用于输送气态的人工煤气、天然气、液化石油气，后者主要用于输送天然气。和钢管比较，施工工艺简单，有一定的柔韧性，更主要的是不用作防腐处理，将节省大量的工序。缺点就器械性不如钢管，施工中特别的注意热力供暖的安全间距，并且不能裸露于空气中阳光下，并且对化学物品敏感，防止污水管道的泄露造成伤害。
发明内容
本发明目的就是提供一种预应力混凝土用波纹管。
本发明是通过以下技术方案实现的：
一种预应力混凝土用波纹管，它是由下述重量份的原料组成的：
高密度聚乙烯80-85、白矿油0.8-1、色母粒0.2-0.3、3-缩水甘油醚氧基丙基三甲氧基硅烷1-2、葵二酸二辛酯2-3、丙烯醇1-2、三氯异氰尿酸0.7-1、八钼酸铵0.1-0.2、三氧化二锑1-2、硅酸钾2-3、大理石粉3-4、复合填料5-10；
所述的复合填料是由下述重量份的原料组成的：
叶腊石20-24、凹凸棒土10-16、玉石3-5、聚二甲基硅氧烷0.6-1、双咪唑烷基脲1-2、桉树油1-2、氧化聚乙烯蜡2-4；
将上述叶腊石、凹凸棒土与玉石混合，球磨均匀，加入氧化聚乙烯蜡，在80-120℃下保温搅拌3-6分钟，降低温度为40-50℃，加入聚二甲基硅氧烷，600-1000转/分搅拌分散10-13分钟，依次加入双咪唑烷基脲、桉树油，充分球磨，造粒，粒径为2-4μm，即得所述复合填料。
一种预应力混凝土用波纹管的制备方法，包括以下步骤：
将上述各原料混合，在120-140℃温度下进行搅拌，搅拌均匀后自动冷却，经振动筛过后，自动上料，由双螺杆挤出机经高温高压挤出，经成型机将产品拉出后，由切割机定长切割，送入扩口机，扩口完成后包装入库。
本发明的优点是：
本发明的波纹管环保，质重，改善了目前聚乙烯波纹管质量轻，在混凝土施工中易上浮的缺陷，具有很好的拉伸强度和环刚度。
