技术领域
本发明涉及高分子材料领域，具体涉及一种新型聚乙烯地暖管及制备方法。
背景技术
寒冷的冬季到来时，“保暖防寒”日渐成为人们谈论的热点话题。地暖全称为地板辐射采暖，是一种基于地面的蓄热、传热技术。地暖管主要由塑料加工而成，地暖管埋于地下，对管道的稳定性、承压性能、刚度、强度有很高要求。同时，有的塑料管道外表面耐划、耐磨性差，很容易就出现裂痕。地暖管埋于建筑水泥中，更换维修非常困难，当出现产品质量问题，将造成严重的财产安全事故。因此，国家标准对地暖管的性能要求很高，以保障其安全使用。
聚乙烯为典型的热塑性塑料，由于PE管材具有无毒、无味、无臭、良好的耐寒、耐热性和化学稳定性、较高的刚性和韧性，以及机械性能好、安装方便等诸多优点，被广泛的应用于建筑给、排水，埋地排水管、输气管及电讯工程等领域。普通的聚乙烯管材作为地暖管使用时，耐划、耐磨性差，很容易就出现裂痕，因此需要对地暖管进行改进。
