Problems solved by technology

[0005] The purpose of the present invention is to provide an impact-resistant polyethylene plastic pipe and its preparation method, which not only overcomes the defects of ultra-high molecular weight polyethylene pipes, such as difficulty in processing and forming, poor stress resistance, and easy cracking, but also retains the traditional ultra-high molecular weight polyethylene pipe. The excellent impact strength of polyethylene pipes also improves wear resistance and creep resistance, and endows them with antibacterial properties. The preparation method is hygienic, non-toxic and pollution-free, and is suitable for large-scale promotion and production

Abstract

The invention relates to the technical field of composite materials, and in particular, relates to an impact-resistant polyethylene plastic pipe and a preparation method thereof; ultrahigh molecular weight polyethylene is used as a main raw material, the surface of the ultrahigh molecular weight polyethylene is modified by an ultraviolet radiation cross-linking technology, and the polyethylene plastic pipe is prepared by adding polyethylene wax grafted polysiloxane and a quaternized nano ceramic powder processing aid, so that the defects that the ultra-high molecular weight polyethylene pipe is difficult to process and form, poorer in stress resistance and easy to crack are overcome, and the excellent impact strength of a traditional ultra-high molecular weight polyethylene pipe is reserved; the wear resistance and creep resistance are also improved, and the impact-resistant polyethylene plastic pipe is endowed with antibacterial properties; and the preparation method is sanitary, non-toxic and pollution-free, and is suitable for large-scale popularization and production.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an impact-resistant polyethylene plastic pipe and a preparation method thereof. Background technique [0002] With the rapid development of society and the continuous advancement of science and technology, the proportion of polymer materials used in agricultural and industrial production continues to increase, and the application of plastic pipes is becoming more and more extensive. Ultra-high molecular weight polyethylene (UHMWPE) is a linear structure polyethylene with a viscosity average molecular weight of more than 1.5 million, a crystallinity of 65-85%, and a density of 0.92-0.96g / cm 3 . The extremely high relative molecular weight endows it with extraordinary performance and becomes a new type of thermoplastic engineering plastic with excellent performance. It has comprehensive properties such as wear resistance, impact resistance, self-lubricating, corrosion...
