Problems solved by technology

However, in the long-term use of plastic pipes for hot and cold water, bacteria and microorganisms are easy to breed. Bacteria and microorganisms in the pipes multiply and adhere to the pipes, resulting in poor fluid transportation in the pipes, and even blockage of small diameter pipes. The serious thing is that the bacteria and microorganisms that grow will cause secondary pollution to the water quality, seriously endangering our living environment, and this problem needs to be solved urgently

Abstract

The invention discloses a plastic composite pipe with an antibacterial function and for hot and cold water. The plastic composite pipe comprises the following main components by mass: 100 parts of a matrix, 15 to 30 parts of glass fibers, 0.6 to 3.2 parts of a silver-loaded antibacterial agent and 0.006-0.096 part of a coupling agent, wherein the matrix is any one of selected from the group consisting of PPR, PB, PPB, PE-RT, PE-X, WPP and C-PVC; the glass fibers can enhance the mechanical properties of the pipe; and the silver-loaded antibacterial agent can effectively improve the antibacterial properties of the pipe and avoid secondary pollution during water circulation of a sponge city. According to the invention, the silver-loaded antibacterial agent is added to improve the antibacterial properties of the pipe and prolong the service life of the pipe, and the pipe is widely applicable to the field of hot and cold water transportation.

Description

technical field [0001] The invention belongs to the technical field of composite pipes, and in particular relates to a plastic composite pipe with antibacterial function for hot and cold water. Background technique [0002] Plastic pipes for hot and cold water are mainly used for the transportation of domestic water, the connection of radiators and floor heating, etc. They have the advantages of high temperature resistance, high pressure resistance, corrosion resistance, convenient transportation, and easy installation. However, in the long-term use of plastic pipes for hot and cold water, bacteria and microorganisms are easy to breed. Bacteria and microorganisms inside the pipe multiply and attach to the pipe, resulting in poor fluid transportation in the pipe, and even blockage of small diameter pipes, which is even more serious. The serious thing is that the bacteria and microorganisms that grow will cause secondary pollution to the water quality, seriously endangering ou...
