Description
技术领域
本发明属于防水材料技术领域，尤其涉及一种聚氯乙烯防水卷材。
背景技术
聚氯乙烯本色为微黄色半透明状，有光泽。透明度胜于聚乙烯、聚丙烯，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。常见制品：板材、管材、鞋底、玩具、门窗、电线外皮、文具等。是一种使用一个氯原子取代聚乙烯中的一个氢原子的高分子材料。
聚氯乙烯简称PVC，由氯乙烯在引发剂作用下聚合而成的热塑性树脂。是氯乙烯的均聚物。氯乙烯均聚物和氯乙烯共聚物统称为氯乙烯树脂。PVC为无定形结构的白色粉末，支化度较小。工业生产的PVC分子量一般在5万～12万范围内，具有较大的多分散性，分子量随聚合温度的降低而增加；无固定熔点，80～85℃开始软化，130℃变为粘弹态，160～180℃开始转变为粘流态；有较好的机械性能，抗张强度60MPa左右，冲击强度5～10kJ/m2；有优异的介电性能。但对光和热的稳定性差，在100℃以上或经长时间阳光曝晒，就会分解而产生氯化氢，并进一步自动催化分解，引起变色，物理机械性能也迅速下降，在实际应用中必须加入稳定剂以提高对热和光的稳定性。PVC很坚硬，溶解性也很差，只能溶于环己酮、二氯乙烷和四氢呋喃等少数溶剂中，对有机和无机酸、碱、盐均稳定，化学稳定性随使用温度的升高而降低。PVC溶解在丙酮-二硫化碳或丙酮－苯混合溶剂中，用于干法纺丝或湿法纺丝而成纤维，称氯纶。具有难燃、耐酸碱、抗微生物、耐磨并具有较好的保暖性和弹性。
