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, in particular to an impact-resistant polyethylene plastic pipe and its preparation method, which uses ultra-high molecular weight polyethylene as the main raw material, and modifies its surface through ultraviolet radiation crosslinking technology, and adds Polyethylene wax grafted with polysiloxane and quaternized nano-ceramic powder processing aids to prepare polyethylene plastic pipes, not only overcomes the defects of ultra-high molecular weight polyethylene pipes, such as difficulty in processing, poor stress resistance, and easy cracking, but also retains The excellent impact strength of traditional ultra-high molecular weight polyethylene pipes is improved, the wear resistance and creep resistance are also improved, and antibacterial properties are endowed. The preparation method is hygienic, non-toxic and pollution-free, and is suitable for large-scale promotion 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 progress of science and technology, the application ratio of polymer materials 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 thermoplastic engineering plastic with excellent performance. It has the incomparable wear resistance, impact resistance, self-lubrication, corrosion resistance, low temperat...
