Description

环保PVC软管
技术领域
本发明涉及环保PVC软管。
背景技术
聚氯乙烯（PVC）为微黄色半透明状，有光泽。透明度优于聚乙烯、聚苯烯，差于聚苯
乙烯，随助剂用量不同，分为软、硬聚氯乙烯，软制品柔而韧、手感粘，硬制品的硬度高于低密度聚乙烯，而低于聚丙烯，在屈折处会出现白化现象。聚氯乙烯的性能比较稳定，不易被酸、碱腐蚀，对热比较耐受；具有阻燃、耐化学药品性高、机械强度和电绝缘性能高等优点。
聚氯乙烯（PVC）用于制造各种软硬管材，并被广泛应用到工业、农业和广大居民生
活中。随着社会经济的不断发展，对聚氯乙烯质量的要求也越来越高。现有技术中的聚氯
乙烯软管，常用的PVC 软管的耐低温性能差、脆性大、韧性强度低、抗老化性能差、安全性能低、运输和安装不便，制作成本高，达不到生产和生活的的要求。现有技术中提到一种卫浴洁具用纳米碳酸钙改性螺旋缠绕PVC 软管的组合屋及其制备方法，但是这种材料制得的软
管耐热性能较好，耐低温性能较差。
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，提供一种耐低温、性能优良、有效提高PVC软管使用寿命的高韧性环保PVC软管材料。
为解决上述技术问题，本发明所采取的技术方案是：环保PVC软管，由以下重量份的成分组成：
聚氯乙烯树脂 40～80；
热塑性聚氨酯弹性体 10～15；
硬脂酸 10～20；
三氧化二锑 0.1～1.5；
碘酊 4～5；
竹醋粉 2～4；
五水偏硅酸钠 0.4～0.6；
碳黑 1～5；
聚碳酸酯 10～20；
纳米碳酸钙 2～4。
本发明高韧性环保PVC软管材料的优点是：本发明采用在PVC 树脂中加入热塑性聚氨酯弹性体、增塑剂、热稳定剂、抗静电剂、阻燃剂，增强了PVC 软管的耐低温性能、柔韧性、抗静电性能和阻燃性，制备的PVC 复合软管综合性能好，不易老化，可运用于低温油，气体或液体的储藏和使用过程中。
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；
环保PVC软管，由以下重量份的成分组成：
聚氯乙烯树脂 40～80；
热塑性聚氨酯弹性体 10～15；
硬脂酸 10～20；
三氧化二锑 0.1～1.5；
碘酊 4～5；
竹醋粉 2～4；
五水偏硅酸钠 0.4～0.6；
碳黑 1～5；
聚碳酸酯 10～20；
纳米碳酸钙 2～4。
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。
