Pressure-resistant anti-oxidation and anti-bacterium PP-R (polypropylene random) cold and hot water pipe

Abstract

The invention relates to an pressure-resistant anti-oxidation and anti-bacterium PP-R (polypropylene random) cold and hot water pipe, which comprises a pipe body and is characterized in that the pipe body is of a multilayer structure and comprises a pressure-resistant layer, a graphite layer, a black high-density polyethylene layer, a nanometer film layer and a PP-R anti-bacterium layer form outside to inside. The pressure-resistant anti-oxidation and anti-bacterium PP-R cold and hot water pipe has the effects that the PP-R cold and hot water pipe provided by the invention is provided with a metal layer, so that the structure intensity of the pipe can be greatly improved, the pressure bearing capability of the pipe is high, cracking and damage cannot easily occur, the carbon black of the graphite layer has an excellent light shielding effect on polyethylene, the black high-density polyethylene layer blocks sunlight, and the PP-R anti-bacterium layer at the inner layer is prevented from aging. The permeation of air into the PP-R anti-bacterium layer is perfectly isolated by nanometer titanium dioxide, the inner layer is the PP-R nanometer anti-bacterium layer, and the inner wall of the PP-R nanometer anti-bacterium layer is in direct contact with water flow, so the problem of bacterium growth due to oxygen permeation is solved. The pressure-resistant anti-oxidation and anti-bacterium PP-R cold and hot water pipe has the advantages that the market capacity is great, the prospects are wide, and great market values and social values are realized.

Description

technical field [0001] The invention relates to a pipe material, in particular to a pressure-resistant, anti-oxidation and antibacterial PP-R hot and cold water pipe. Background technique [0002] PP-R pipe is also called three-type polypropylene pipe. It has many advantages such as light weight, corrosion resistance, no scaling, and long practical life. At the same time, because of its high cost performance, it has become the material of choice for water pipe renovation. However, its poor compression resistance, weak anti-light aging ability, single-layer PP-R light transmission, strong oxygen penetration, and easy breeding of bacteria. The pressure resistance is poor, and when the pressure it receives is high, it is easy to cause cracking and damage to the pipe wall, and its surface is also prone to scratches, causing certain safety hazards. Contents of the invention [0003] The invention provides a PP-R hot and cold water pipe with strong pressure resistance, anti-...
