Problems solved by technology

However, its nano-antibacterial agent is not fully fused with polyethylene, and the inner layer and outer layer cannot be fused even more, which reduces the toughness and fracture resistance of the PE pipe as a whole and shortens the service life.

Abstract

An anti-mildew, anti-bacterial and anti-virus PE pipe belongs to the technical field of PE pipes, which is composed of polyethylene, phenolic resin, ceramic particles, carbon fiber, graphite, glass fiber, nano-bamboo charcoal fiber, nano-silver powder, compatibilizer, and antioxidant It is prepared; its beneficial effect is: mixing phenolic resin, compatibilizer and antioxidant in polyethylene, combining the rigidity characteristics of ceramic particles and graphite, and the tensile characteristics of carbon fiber and glass fiber, plus nano-bamboo charcoal fiber 1. The antibacterial properties of nano-silver powder can greatly improve the toughness and fracture resistance of polyethylene, and can also make the pipe have anti-mildew, anti-bacterial and anti-virus properties; Improve the toughness effect; the combination of specific raw materials and preparation methods enables PE pipes to achieve a well-balanced increase in tensile strength, bending strength and elongation at break, effectively improving the comprehensive mechanical properties and having anti-mildew, anti-bacterial and anti-virus properties.

Description

technical field [0001] The invention relates to the technical field of PE pipes, in particular to an anti-mildew, anti-bacteria and anti-virus PE pipe. Background technique [0002] PE (polyethylene) refers to a polymer formed by free radical polymerization of ethylene monomer. It is one of the most widely used general-purpose plastics. Chemically aggressive thermoplastic. [0003] PE pipe is mainly made of polyethylene particles, and various raw materials are mixed in a profile forming machine to form a pipe. Widely used in building water supply, building drainage, urban water supply, buried drainage pipes, building heating, gas transmission and distribution, gas pipelines, electrical and telecommunications protection casings, industrial pipes, agricultural pipes, etc. [0004] In the application of PE pipes, after long-term contact with water, bacteria are easy to breed, resulting in a greasy feel, leading to serious bacterial contamination. The existing PE pipe antibac...
