Abstract

The invention discloses a high-strength PE pipe. The PE pipe is synthesized from the following materials in parts by weight: 100-150 parts of polyethylene (PE), 10-30 parts of a compatilizer, 10-25 parts of an antioxidant, 15-30 parts of a flexibilizer, 10-15 parts of epoxy resin, 10-50 parts of glass fiber, 2-8 parts of a lubricant and 1-5 parts of concentrated color master batch. Through the preparation method, the defective rate of the PE pipe can be obviously reduced, and the production efficiency is enhanced. The method has good universality and can adapt to production of most products. According to the method, the daily use stability and wear resistance of the PE pipe can be effectively improved, meanwhile, the PE pipe has good heat resistance, and the service life of the PE pipe canbe better prolonged; moreover, the strength and toughness of the pipe are greatly enhanced in a manner of reprocessing the preliminarily formed PE pipe, so that the PE pipe is suitable for more severe environments, and the application range is expanded.

Description

technical field [0001] The invention relates to a pipe material and a preparation method thereof, in particular to a high-strength PE pipe material and a preparation method thereof, and belongs to the technical field of pipe materials. technical background [0002] Polyethylene (PE) is a thermoplastic resin obtained by polymerization of ethylene. Because of its high strength, high temperature resistance, corrosion resistance, non-toxicity, wear resistance and other characteristics, it can be processed into films, wire and cable sheaths, pipes, various hollow products, injection molding products, fibers, etc., widely used in agriculture, packaging, Electronics, machinery, automobiles, daily sundries, etc. Especially in the field of pipe manufacturing, PE pipes are ideal replacement products for traditional steel pipes and PVC (polyvinyl chloride) pipes because they will not rust and are non-toxic. In recent years, with the rapid development of science and technology and the...
