Nanometer antimicrobial polyethylene tube material and preparing method thereof

Abstract

The invention relates to a nanometer antimicrobial polyethylene tube material. The nanometer antimicrobial polyethylene tube material is prepared from the following raw materials by weight: 90-95 parts of polyethylene, 1-2 parts of stabilizer, 1-2 parts of processing modifier, 1-2 parts of plasticizer, 1-2 parts of a photomask agent, 1-2 parts of antioxidant and 2-3 parts of a nanometer antimicrobial agent, wherein styrene or divinyl benzene is used as the processing modifier, an ultraviolet resisting absorbent is used as the stabilizer, an antimicrobial adopting metallic silver or metallic gold as a main antimicrobial ingredient is used as the nanometer antimicrobial, and the grain diameter of the nanometer antimicrobial is 20-50nm through the modification of a titanate class coupling agent. Compared with the prior art, the nanometer antimicrobial polyethylene tube material has the beneficial effects that the nanometer antimicrobial polyethylene tube material has the characteristics of simple manufacture technology and easiness in production; due to the addition of the nanometer antimicrobial, the photomask agent and the antioxidant to the tube material, sanitary and health requirements are effectively met, harmful bacteria, fungi and mildew in water are killed, the propagation of the harmful bacteria, fungi and mildew is effectively inhibited, and the market prospects are wide.

Description

technical field [0001] The invention relates to the technical field of pipes, in particular to a nano antibacterial polyethylene pipe and a preparation method thereof. Background technique [0002] In recent years, polyethylene pipes have become the second largest consumption of plastic pipes in the world after PVC, and are widely used in water supply, agricultural irrigation, gas transmission, sewage discharge, mine mortar transportation and other projects as well as oil fields, chemicals, post and telecommunications, etc. In the field, under outdoor conditions such as transportation, storage, and construction, the existing polyethylene pipes will undergo aging degradation, mechanical properties will decline, and will become brittle within one year, with poor mechanical properties, poor impact resistance, and poor rigidity. The installation density of clamps and hangers is high; due to the high thermal expansion coefficient, flexible joints are used in plastic pipelines, es...

[0002] In recent years, polyethylene pipes have become the second largest consumption of plastic pipes in the world after PVC, and are widely used in water supply, agricultural irrigation, gas transmission, sewage discharge, mine mortar transportation and other projects as well as oil fields, chemicals, post and telecommunications, etc. In the field, under outdoor conditions such as transportation, storage, and construction, the existing polyethylene pipes will undergo aging degradation, mechanical properties will decline, and will become brittle within one year, with poor mechanical properties, poor impact resistance, and poor rigidity. Cards and hangers have a high density; due to the high coefficient of thermal expansion, flexible joints are used in plastic pipelines, especially as hot water pipes, with a large coefficient of thermal expansion, and there are many thermal compensation measures such as expansion joints or various bends.
