Abstract

The invention discloses a high-strength antibacterial PE water supply pipe, and belongs to the technical field of water pipes. The PE water supply pipe is prepared from the following raw materials in parts by weight: 42.5 to 60.8 parts of polyethylene resin, 20.3 to 30.3 parts of polyvinyl chloride resin, 1.2 to 4.5 parts of talcum powder, 1.5 to 2 parts of light calcium carbonate, 3.1 to 4.1 parts of antibacterial composition, 2.1 to 4.3 parts of cross-linking agent, 0.4 to 0.8 part of coupling agent, 0.6 to 1 part of stabilizer, 0.2 to 0.5 part of antioxidant and 0.2 to 0.5 part of dispersing agent. The invention also discloses a production process of thewater supply pipe. The process comprises the steps: mixing raw materials; and adding the mixture into a double-screw extruder for granulating, carrying out melt extrusion, and performing cooling, cutting, expanding and packaging. The prepared water supply pipe has good rigid strength and excellent stability, and the cheap inorganic metal particles are used for replacing silver ions, so that a considerable bactericidal effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of water pipes, and relates to a high-strength antibacterial PE water supply pipe and a production process thereof. Background technique [0002] PE (metallocene linear low-density polyethylene) material is widely used in the field of water supply pipe manufacturing due to its high strength, high temperature resistance, corrosion resistance, and non-toxicity. Because it will not rust, it is an ideal pipe to replace ordinary iron water supply pipes; metallocene linear low-density polyethylene is a non-inert material, except for a small amount of strong oxidants, it can resist corrosion by various chemicals. The PE water supply pipe manufactured by it has low energy consumption for water delivery, low energy consumption for living, light weight, small water flow resistance, easy and fast installation, low cost, long life, and heat preservation function. [0003] The microorganisms in the water supply pipe hav...
