Abstract

The invention relates to an antibacterial pe pipe. 5% of antibacterial master batch is added in and mixed with pe resin. The temperature of the mixture is raised to 170-180 DEG C. Then the mixture undergoes single-screw extrusion, cooling and vacuum forming, secondary cooling, tertiary cooling, spray code printing, traction, cutting and other procedures. The antibacterial master batch is mixed with dichloroethenyl salicylamide and thiazole mixture, paint, dispersant, carrier resin and liquid lubricant. The mixture is heated and melted down and then extruded by a twin screw for purpose of pelleting. A plastic water supply pipe made of the antibacterial pe pipe can inhibit and prevent the attachment and the growth of microorganisms, kill bacteria, fungus, mould and other bacterium species in the water supply pipe, strongly inhibit colibacillus and staphylococcus aureus and has an antibiosis rate of 99 percent. The antibacterial pe pipe has simple production process and low cost.

Description

1. Technical field: [0001] The invention relates to a plastic water supply pipe, in particular to an antibacterial PE pipe. 2. Background technology: [0002] Due to its erosion resistance, corrosion resistance, long life and other factors, plastic pipes are widely used in real life. With the advancement of science and technology and the change of people's consumption concepts, people put forward new requirements for the improvement of quality of life and health. , Plastics with special functions were born and developed rapidly. However, conventional water supply pipes are likely to cause secondary pollution to water due to long-term contamination and bacterial attack. [0003] Therefore, it is an urgent problem to provide a new type of pipe with the function of conventional plastic pipe and antibacterial effect. 3. Contents of the invention: [0004] The purpose of the present invention is to overcome the existing problems and provide a pipe with antibacterial PE. [0...
