Description

塑料专用料及基于该专用料的方管芯层发泡缠绕管的制备 方法
技术领域
本发明涉及一种塑料管，尤其涉及一种塑料专用料及基于该专用料的方管芯层发泡缠绕管的制备方法。
背景技术
塑料缠绕管作为一种化学建材，具有力学性能优异、耐腐蚀、环境友好、使用寿命长的特点。但是，塑料缠绕管普遍存在单重高、抗冲击性能差的缺陷，树脂材料的缠绕结构往往无法满足高载荷等特殊工况条件的要求，需要通过增加管材的单重提高管材的力学性能。芯层发泡作为一种新型的结构单元，具有高模量、单重低、优异尺寸稳定性、冲击强度高等优点，可在保持单重不变的情况下提高缠绕管的力学性能、尺寸稳定性以及其他性能。
发明专利CN104558780A报道了“一种高密度聚乙烯微孔发泡管材及其制备方法”。专利通过添加主发泡剂、辅助发泡剂和发泡助剂对普通管材进行发泡，获得力学性能优良、低压给水和刚性承载能力一般的塑料管材。但是该塑料管材存在以下几个缺陷：1)普通管材发泡，不易控制发泡后的泡孔结构；2)管材发泡后，整体的强度达不到要求；3)生产工艺及发泡过程不好控制。
发明内容

(2)主挤出机中的熔融料通过复合模头进入机头模具，辅挤出机中的熔融料通过复合外模进入机头模具，挤出后经过方管定径套真空定径、发泡，成型为中空矩形塑料发泡管；
(3)将中空矩形塑料发泡管送入缠绕装置进行螺旋缠绕，并用热熔胶焊接连接，生产出具有微孔结构的方管芯层发泡缠绕管。
本发明的有益效果是：
1、采用一次挤出成型生产，工艺简单，设备投入少，生产效率高；
2、主挤出机挤出圆管时，发泡剂反应放出气体，圆管中出现微孔结构，然后经过方形定径套，将圆管固定成具有微孔结构的方形管；
3、提高了塑料缠绕管的抗击冲性能，降低了管材的生产成本。
