Description

一种耐热PVC管配方
技术领域
本发明涉及一种耐热PVC管配方，属于塑料技术领域。
背景技术
聚氯乙烯，英文简称PVC（Polyvinyl chloride)，是氯乙烯单体（vinyl chloridemonomer, 简称VCM）在过氧化物、偶氮化合物等引发剂；或在光、热作用下按自由基聚合反应机理聚合而成的聚合物。氯乙烯均聚物和氯乙烯共聚物统称之为氯乙烯树脂。
PVC为无定形结构的白色粉末，支化度较小，相对密度1.4左右，玻璃化温度77~90℃，170℃左右开始分解，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。
PVC材料经常用于我们的生活中，尤其是PVC管。现有市场对PVC管的需求量正在逐年增加，未来社会对PVC管仍将继续增大。随着社会城市化、科技化、人性化的发展，PVC管行业的高速发展，PVC管越来越贴近人们的生活，随之而来的是PVC管使用量的增加。这就需要一种耐热、抗老化、抗光氧化、韧性高，热稳定性好、阻燃性好，耐酸碱腐蚀的PVC管。
