Description

Novel anti freezing pipe that strikes of PPR

Technical Field

The present disclosure generally relates to the technical field of PPR pipe production, and specifically relates to a novel PPR anti-freezing impact pipe.

Background

PPR is short for English polypropylene random copolymer. The PPR pipe is a renewal product of UPVC water supply pipe, aluminum plastic pipe, PE-X pipe and PE-RT pipe, and because it uses random copolymerization technology, the strength and high temperature resistance of polypropylene are well guaranteed, thus becoming the main force of water pipe material.

Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipelines, the PPR pipe has the advantages of energy conservation, material saving, environmental protection, light weight, high strength, corrosion resistance, smooth inner wall, no scaling, simple and convenient construction and maintenance, long service life and the like, and is widely applied to the building industry, municipal administration, industry and agricultural field such as building water supply and drainage, urban and rural water supply and drainage, urban gas, electric power and optical cable sheaths, industrial fluid transportation agricultural irrigation and the like. The existing PPR pipe is low in toughness, cannot meet the requirements of the market for PPR products, is relatively fragile when being in a protective environment in winter, is easy to damage during use and is large in construction limitation.

Disclosure of Invention

In view of the above-mentioned drawbacks and deficiencies of the prior art, it would be desirable to provide a novel PPR pipe with improved toughness, reduced damage rate, and better suitability for construction requirements.

In a first aspect, the present application provides a novel PPR cryo-impact resistant tube comprising:

the inner side of the PPR pipe body is provided with an antibacterial layer;

the creep resistant layer is arranged on the outer side of the PPR pipe body;

an anti-oxidation layer disposed outside the creep resistant layer;

and the anti-impact layer is arranged on the outer side of the anti-oxidation layer.

According to the technical scheme provided by the embodiment of the application, the creep-resistant layer is made of the PPR base material and the glass fiber material.

According to the technical scheme provided by the embodiment of the application, the antibacterial layer is made of the PPR base material and the nano silver material.

According to the technical scheme that this application embodiment provided, the shock resistance layer adopts PPR substrate and POE plastic materials to make.

According to the technical scheme provided by the embodiment of the application, the oxidation resistant layer is made of an EVOH material.

According to the technical scheme provided by the embodiment of the application, the inner wall of the oxidation resistant layer is connected with the creep resistant layer through the hot melt adhesive; the outer wall of the oxidation resistant layer is connected with the impact resistant layer through hot melt adhesive.

To sum up, this application specifically discloses a novel specific structure of PPR pipe anti freezing impact pipe. This application sets up antibiotic layer through the inboard at PPR tubular product to set gradually creep resistant layer, oxidation resisting layer and shock resistance layer in the outside of PPR tubular product and along its radial extending direction, change current tubular product structure, make tubular product possess the effect of shock resistance, anti-oxidant and anti high temperature creep, be applicable to construction use under any temperature, improve the application scope of tubular product.
