Description

【Technical field】 [0001] The invention belongs to the technical field of polymers, and in particular relates to a polyethylene water supply pipe material and a preparation method thereof. 【Background technique】 [0002] Polyethylene pipes are more and more widely used in gas pipes due to their outstanding chemical corrosion resistance, low temperature resistance, heat resistance, wear resistance and welding performance, no pollution to the conveying medium, low manufacturing and installation costs, and long service life. Transportation, water supply, sewage, heat supply, agricultural irrigation and mine fine particle solid transportation and other fields. In addition to the above-mentioned properties, the most basic requirement for pressure pipelines is to have excellent hydrostatic resistance. [0003] For polyethylene pressure pipes, there are two forms that affect pipe damage, long-term creep damage and rapid crack growth damage. Among them, resistance to long-term cree...
