Abstract

本发明公开了一种PVC软管，由以下重量份的成分组成：PVC树脂30～60；聚对苯二甲酸丙二醇酯2～5；聚乙烯醇缩丁醛4～5；磷酸三酯2～4；对苯二酚0.4～0.6；有机硅混炼胶2～5；丁苯橡胶10～15；碳黑1～3；石蜡1～2。本发明的高韧性聚氯乙烯管材使用了碳化硅晶须，可以有效地加强管材内部的结构，使管材之间的力学强度、韧性都得到了提高。另外，提高管材的抗老化性；润滑剂可以在生产过程中，使材料更加均匀、提高了挤出的润滑平整性，也起到了增强内部结构的作用。制得的聚氯乙烯管材具有高韧性、高机械强度的特点。

Description

一种PVC软管
技术领域
本发明涉及一种PVC软管。
 
背景技术
聚氯乙烯管，也称PVC 管，是由氯乙烯单体聚合而成的热塑性高聚物制成的管材，以聚氯乙烯树脂为主要原料，加入适量的抗老化剂、改性剂等，经混炼、压延、真空吸塑等工艺而成的材料。PVC 管抗腐蚀能力强、易于粘接、PVC 对氧化剂、还原剂和强酸都有很强的抵抗力。然而它能够被浓氧化酸如浓硫酸、浓硝酸所腐蚀并且也不适用与芳香烃、氯化烃接触的场合。但是，PVC 管，特别是UPVC 管耐热性能差，且在60℃以上环境抗拉强度下降，低温环境下硬聚氯乙烯塑料排水管抗冲击强度降低。在运输、安装及使用过程中，易发生脆性破坏；另外，PVC 管承受冲击的性能也较差。
发明内容
针对现有技术存在的不足，本发明所要解决的技术问题是，提供一种具有良好的耐低温性能、柔韧性和抗静电性能且能够满足低温运输的耐磨耐老化的PVC软管。
为解决上述技术问题，本发明所采取的技术方案是：一种PVC软管，由以下重量份的成分组成：
PVC树脂                          30～60；
聚对苯二甲酸丙二醇酯              2～5；
聚乙烯醇缩丁醛                              4～5；
磷酸三酯                            2～4；
对苯二酚                            0.4～0.6；
有机硅混炼胶                      2～5；
丁苯橡胶                          10～15；
碳黑                              1～3；
石蜡                              1～2。
本发明一种PVC软管的优点是：本发明的高韧性聚氯乙烯管材使用了碳化硅晶须，可以有效地加强管材内部的结构，使管材之间的力学强度、韧性都得到了提高。另外，提高管材的抗老化性；润滑剂可以在生产过程中，使材料更加均匀、提高了挤出的润滑平整性，也起到了增强内部结构的作用。制得的聚氯乙烯管材具有高韧性、高机械强度的特点。
具体实施方式
下面结合具体实施例对本发明做进一步详细说明；
一种耐磨耐老化的PVC软管，由以下重量份的成分组成：
PVC树脂                          30～60；
聚对苯二甲酸丙二醇酯              2～5；
聚乙烯醇缩丁醛                              4～5；
磷酸三酯                            2～4；
对苯二酚                            0.4～0.6；
有机硅混炼胶                      2～5；
丁苯橡胶                          10～15；
碳黑                              1～3；
石蜡                              1～2。
当然，上述说明并非是对本发明的限制，本发明也并不限于上述举例，本技术领域的普通技术人员，在本发明的实质范围内，作出的变化、改型、添加或替换，都应属于本发明的保护范围。
