Description

一种生产简单的PVC硬管的加工工艺
技术领域
本发明涉及PVC领域，具体地说是一种生产简单的PVC硬管的加工工艺。
背景技术
PVC主要成份为聚氯乙烯，另外加入其他成分来增强其耐热性，韧性，延展性等。在合成过程中PVC管材需要多种原材料，成本相对较高，由于PVC管有着较高的稳定性经常被用于水管等运输液体的管道，在使用中一旦因外力挤压发生断裂就会发生大量液体泄漏的事故，目前市场上的硬质pvc管材耐压强度都有待提高。
发明内容
针对现有技术的不足，本发明提供一种生产简单的PVC硬管的加工工艺。
本发明的技术方案如下：一种生产简单的PVC硬管的加工工艺，包括以下步骤：
（1）首先将PVC120-140份、氯化聚乙烯5-9份、纳米碳酸钙8-25份、玻璃纤维2-5份、钛白粉3-7份、PE蜡1-4份、钙锌稳定剂1-5份、ACR4-6份加入高速搅拌机内进行搅拌，至物料温度达到100-140℃停止搅拌。
（2）然后将物料输送到冷混机中搅拌降温，待物料温度降至35-50℃时，出料。
（3）最后将混合料送至双螺杆挤出机中挤出成型制成管材，双螺杆挤出机加工温度为150-200℃。
本发明具备以下良好效果：
（1）本发明制备的PVC管抗压抗冲击性能优良，适合制作各种高强度要求的工件。
（2）本发明中PVC管材易于加工，各原料组分之间相同性好。
（3）本发明的PVC管材成本低廉、经济效益显著。
具体实施方式
下面结合具体实施例对本发明进一步说明。
