Description
技术领域
本发明主要涉及一种PE给水管，属于管材领域。
背景技术
PE（茂金属线性低密度聚乙烯）材料由于其强度高、耐高温、抗腐蚀、无毒等特点，被广泛应用于给水管制造领域。因为它不会生锈，所以，是替代普通铁给水管的理想管材；茂金属线性低密度聚乙烯为无惰性材料，除少量强氧化剂外，可耐多种化学药品侵蚀，且不易滋生细菌。众所周知钢管、铸铁管被塑料管所取代的原因不仅是因为塑料管材比其输水能耗低、生活能耗低、重量轻、水流阻力小、安装简便迅速、造价低、寿命长、具有保温功能等，还因为塑料管耐腐蚀、不易滋生微生物等性能优于钢管及铸铁管。
随着城市建设的逐渐扩大，PE给水管也将被用于更加恶劣的环境，持续性高低温、酸碱等化学物品腐蚀、持续性高压等，因此进一步改善传统PE给水管的性能，提高产品品质，对于中国现代化建设有很好的促进作用。

所述的改性助剂是由下述重量份的原料组成的：
茂金属线性低密度聚乙烯30-40、聚邻苯二甲酰胺15-20、氮化铝3-4、膨润土润滑脂1-2、硅烷偶联剂KH-5601-2、玫瑰精油1-2、过氧化钙0.1-0.2；
将聚邻苯二甲酰胺加热到120-130℃，加入氮化铝，保温搅拌10-15分钟，冷却至常温，得预混料；将茂金属线性低密度聚乙烯与过氧化钙、硅烷偶联剂KH-560混合，在50-60℃下恒温搅拌20-30分钟，冷却至常温后与上述预混料混合，400-500转/分搅拌分散3-5分钟，加入剩余各原料，搅拌均匀后烘干，造粒，粒径为2-4mm。
一种防老化PE给水管的制备方法，包括以下步骤：
将上述膨润土与异丙基二油酸酰氧基（二辛基磷酸酰氧基）钛酸酯混合，60-70℃下搅拌反应30-40分钟，加入聚丙烯酸钠，充分搅拌后冷却至常温，与剩余各原料混合，送入捏合机，在70-80℃下进行捏合，出料冷却至常温，加入到平行同向旋转双螺杆挤出机进行挤出，在模具中成型，即得所述防老化PE给水管。
本发明的优点是：
本发明生产的PE给水管抗老化性能强，其中加入的改性助剂增加了各原料与PE聚合物的界面粘接强度，可以形成良好的物理缠结，改善了成品的柔韧性、抗压、弯曲强度等性能。
