Abstract

The invention discloses an antibacterial PE water supply pipe. The antibacterial PE water supply pipe is prepared from the following raw materials in parts by weight: 80-100 parts of a polyethylene raw material, 20-30 parts of a regenerated polyethylene material, 2-4 parts of an antioxidant, 12-24 parts of a compound antibacterial agent, 1-3 parts of a lubricant, 2-5 parts of a dispersing agent and 1-3 parts of an anti-impact modifier, wherein the compound antibacterial agent contains an inorganic antibacterial material and an organic antibacterial material in a mass ratio of (2-4) to 1, and the inorganic antibacterial material contains Muyu stone sphere powder, zeolite powder, zinc oxide and nano-silver. The antibacterial efficiency of the antibacterial PE water supply pipe reaches above 99%, and the antibacterial cycle is long.

Description

technical field [0001] The invention belongs to the technical field of water supply pipes, in particular to an antibacterial PE water supply pipe. Background technique [0002] Polyethylene (PE for short) is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the lowest operating temperature can reach -100 ~ -70 ° C), good chemical stability, and can withstand most acid and alkali erosion (not resistant to oxidation properties) acid). Insoluble in common solvents at room temperature, low water absorption, excellent electrical insulation. [0003] PE pipes are mainly used to transport gaseous artificial gas, natural gas, liquefied petroleum, and sewage, and the construction process is simple. PE pipe has high strength, high temperature resistance, corrosion resistance, non-toxicity, w...
