Anti-microbial heat preservation composite pipe

Abstract

The invention discloses an anti-microbial heat preservation composite pipe. The anti-microbial heat preservation composite pipe comprises an anti-microbial inner layer, an aluminum alloy layer, a PP-Rprotection pipe layer, an expanded polyethylene heat preservation layer and a weather-proof and scratch-resistant outer layer which are sequentially connected from inside to outside. A first adhesivelayer is arranged between the anti-microbial inner layer and the aluminum alloy layer. A second adhesive layer is arranged between the aluminum alloy layer and the PP-R protection pipe layer. The pipe structure of the anti-microbial heat preservation composite pipe is formed by compositing the multiple layers, an effective anti-microbial property can be achieved, the anti-microbial heat preservation composite pipe is good in anti-microbial effect, safe, free of toxin and lasting in effect and has high heat stability, and meanwhile, due to the design of the aluminum alloy layer, the problem that an existing pipe is large in low temperature brittleness and large in shrinkage percentage is effectively solved and rigidity and operation stability of a whole pipeline system are improved; and the pipe is safe, environment-friendly, capable of achieving efficient heat preservation and long in service life.

Description

technical field [0001] The invention relates to the technical field of pipe fitting processing, in particular to an antibacterial and thermal insulation composite pipe. Background technique [0002] With the vigorous development of building energy conservation and green buildings, people have more and more demands for building insulation and pipe insulation in buildings, especially in the field of home improvement. However, since polypropylene is an organic polymer material, it is easy to be corroded by microorganisms, so the existing polypropylene pipes are easy to breed fungi, especially in a constant humid temperature environment, and the surface becomes dirty after a period of use. A layer of slippery substance will be produced, which is mainly composed of fungi. And because the existing pipelines are difficult to clean once they are installed, the pipelines that produce fungi will cause secondary pollution of water sources and bring potential safety hazards to people. ...

AI Technical Summary

Problems solved by technology

However, since polypropylene is an organic polymer material, it is easy to be corroded by microorganisms, so the existing polypropylene pipes are easy to breed fungi, especially in a constant humid temperature environment, and the surface becomes dirty after a period of use. produces a slippery layer, which is mainly composed of fungi

And because the existing pipelines are difficult to clean once they are installed, the pipelines that produce fungi will cause secondary pollution of water sources and bring safety hazards to people

For the currently commonly used inorganic silver ion antibacterial agents, silver ions with a content exceeding the relevant national health standards will be precipitated during use, which will cause harm to the human body. Other organic small molecule antibacterial agents also have the problem of easy precipitation. antibacterial efficacy

In addition, polypropylene pipes have the problems of low-temperature brittleness and large shrinkage, which makes the existing polypropylene pipes have a low service life and cannot meet the needs of use.
