Problems solved by technology

Generally, it is a single-layer structure, and this kind of tube is mostly white, and the shading effect is not good. If it is used outdoors for a long time, it will provide a good environment for the growth of bacteria, which often leads to the inside of the tube body. Breed a large number of bacteria, which brings great hidden danger to people's life and health

Abstract

The invention discloses an antibacterial water supply pipe, an antibacterial PE composite material and a preparation method thereof. The composite material is composed of the following components by weight: 0.1-1.5 parts of graphene microchip, 95.0-98.5 parts of a PE resin, 0.5-3.0 parts of a dispersant and 0.5 part of an antioxidant. The antibacterial water supply pipe provided by the invention comprises a PE outer wall and an antibacterial inner wall, wherein the PE outer wall and the antibacterial inner wall are shaped by coextrusion; the inner wall is made of the PE resin added with the graphene microchip; and the outer wall is made of the PE resin added with a proper amount of color masterbatch. The above antibacterial water supply pipe has good antibacterial and light-shielding effects, thereby preventing the inner wall from breeding and propagating a large number of bacteria which bring hazards to people's life health.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an antibacterial water supply pipe, an antibacterial PE composite material and a preparation method thereof. Background technique [0002] With the improvement of living standards, people pay more and more attention to health problems, but with the deterioration of the environment, diseases caused by various bacteria are becoming more and more frequent, among which water is closely related to people's life, and the content of bacteria in water directly determines the quality of the water. [0003] Most of the existing water supply pipes suitable for tap water and drinking water are PE pipes. Generally, it is a single-layer structure, and this kind of tube is mostly white, and the shading effect is not good. If it is used outdoors for a long time, it will provide a good environment for the growth of bacteria, which often leads to the inside of the tube body. Breed a la...
