Description

一种HDPE双壁波纹管
技术领域
本发明涉及一种HDPE双壁波纹管，属于塑料管材技术领域。 
背景技术
PE 双壁波纹管80年代初在德国首先研制成功。PE双壁波纹管是一种以聚乙烯为原材料经过挤出和特殊的成型工艺加工而成，内壁光滑，外壁为封闭波纹型的一种新型轻质管材。PE双壁波纹管除了具有普通塑料管所具有的耐腐蚀性好，绝缘性高，内壁光滑，流动阻力小等特点以外，还因采用了特殊的中空环形结构，具有优异的环刚度和良好的强度与韧性，及重量轻，耐冲击性强，不易破损等特点。
目前我国生产PE双壁波纹管的配方现状是：低压聚乙烯（HDPE）+增强填充母料（碳酸钙母粒）+色母，这样的传统模式。但是目前欠缺适用于钢丝骨架增强聚乙烯管材的专用粘结树脂，现有树脂形成的管材力学性能、抗冲击性能、可变形程度、抗老化性能、抗污性能较差。

本发明具有以下显著的技术效果：
1、石墨烯的强度约是普通钢的100倍，是一种强度极大的纳米材料。碳纳米管也具有良好的力学性能，抗拉强度是普通钢的100倍，弹性模量与金刚石相当，是钢的5倍，且结构稳定。将石墨烯和碳纳米管引入原料中，大大改善了管材的力学性能，使管材的抗拉性能、弹性恢复能力显著提升，拉伸强度达到120MPa，拉伸强度大于10倍。N-甲基吡咯烷酮的加入促进了石墨烯和碳纳米管在混合原料中的融合。
2、聚酰亚胺纤维是一种高性能特种纤维，抗张强度可以和玻璃纤维、芳纶甚至碳纤维媲美。本发明原料中加入聚酰亚胺纤维，显著提升了管材的力学性能。甲基丙烯酸甲酯、聚丙烯酰胺的加入与聚酰亚胺纤维形成协同效应，仅可使制品的抗张强度、热变形温度大幅提高，同时其冲击性能也得到极大改善，低温下尤其明显。另外甲基丙烯酸甲酯、聚丙烯酰胺、黄酮醇的加入使PE大分子得到改性，在保证较高拉伸强度的及断裂伸长率的情况下增强了粘结性。
3、原料中采用了蒙托土、白炭黑、硫酸锆与多种树脂HDPE、LDPE 、LLDPE、聚丙烯共混挤出时产生了协同效应，使管材的力学性能、热稳定性产生显著地提升。本产品熔融指数1.5-3.0（5kg砝码）、拉伸强度27MPa、断裂伸长率400%。用本产品生产的管材：内外壁光滑、强度高、柔性好、能有效吸收冲击能量、抗裂性好。
4、当管材用作饮用水、再生水输送时，原料中引入纳米银，可以使管材具有杀菌消毒的功能，并且原料中引入了儿茶素、甘露醇，其多羟基结构也能够起到良好的抗污作用。
5、过氧化苯甲酰、N-异丙基-N’-苯基对苯二胺混合引入原料中，产生协同作用，大大提升了管材的抗老化性能、大大降低了管材的低温脆性。
6、原料中加入蒙脱土可以提高管材的抗冲击、抗疲劳性。加入硫酸锆可以显著增加管材的硬度，加入二氧化钛后管材在进行输水时，可以配合可见光、紫外光进行光催化反应。
