Problems solved by technology

In addition, water pipelines are usually used for many years, causing harmful microorganisms such as bacteria, fungi, molds, and viruses to easily breed in the water pipes. In addition, calcium, magnesium, and lead ions in the water are also prone to scaling, which affects water transportation.
[0003] In order to solve the problem of water pollution, the current common solution is to add purifiers to the water, but the added purifiers are all chemical reagents. Mixing them in water will make the water smell too strong, and long-term drinking will cause harm to the human body.
There are Ag+-based inorganic antibacterial technologies on t

Abstract

The present invention discloses a PP-R self-cleaning kitchen and bath pipe and a preparation method thereof, and the pipe inner layer materials include the following parts by weight of components: 100 parts of random copolymerized polypropylene particles, 1-3 parts of color masterbatch, and 4-6 parts of an antibacterial material. The molecular bonding technique is used for bonding a special effective antimicrobial functional group compound into a very-widely-used polyolefin resin molecular chain to form a molecular bonding antimicrobial material, the molecular bonding antimicrobial material is incorporated into polypropylene and the color masterbatch in a certain percentage, by three-layer co-extrusion technology, the antimicrobial material is sufficiently mixed into the pipe inner wall and processed for molding to form a carrier which can kill and inhibit bacteria, fungi, mold and virus in water, the breeding and proliferation of harmful microorganisms can be prevented, and meanwhile fouling can be prevented. The PP-R self-cleaning kitchen and bath pipe has efficient antibacterial antiviral moldproof effects, and can be used for hot and cold water self-cleaning kitchen and bath pipes.

Description

technical field [0001] The invention relates to a PP-R self-cleaning kitchen and bathroom pipe material and a preparation method thereof, belonging to the field of living building materials. Background technique [0002] At present, due to the discharge of industrial waste gas, waste water and waste residue, the environmental pollution is serious. When the discharged waste enters the surface, it will pollute the groundwater source and cause water pollution. The pollution of water sources has already brought certain impacts on people's lives, and in the process of water delivery, due to the uncleanness of the pipelines, it will cause secondary pollution of water quality. The most direct impact on people's lives is the pollution of household water. In addition, water pipelines are usually used for many years, causing harmful microorganisms such as bacteria, fungi, molds, and viruses to easily breed in the water pipes. In addition, calcium, magnesium, and lead ions in the wate...
