Description

PSP steel-plastic composite pressure pipe with antibacterial function

Technical Field

The utility model relates to a tubular product technical field, in particular to compound pressure pipe is moulded to PSP steel with antibacterial function.

Background

PPR is the abbreviation of English Random copolymerized Polypropylene (Polypropylene-Random). Commonly known as type III polypropylene. The PPR pipe is a renewal product of a galvanized pipe, a UPVC water supply pipe, an aluminum plastic pipe, a PE-X pipe and a PE-RT pipe. Because the polypropylene random copolymerization technology is used, the strength and the high temperature resistance of the polypropylene are well ensured, so that the polypropylene random copolymerization polypropylene pipe becomes the main force of water pipe materials, the PPR pipe is widely applied to the fields of building industry, municipal administration, industry and agriculture, such as building water supply and drainage, urban and rural water supply and drainage, urban gas, electric power and optical cable sheaths, industrial fluid conveying, agricultural irrigation and the like, and the fields of municipal administration, industry and agriculture, and in recent years, the PPR pipe industry in China shows a high-speed development situation along with the continuous increase of market demands of the industries, such as building industry, municipal engineering, hydraulic engineering, agriculture, industry and the. According to a prospective network survey, the plastic pipeline production in 2009 is 580.4 ten thousand tons and the same ratio is increased by 18.9%, and the plastic pipeline production in 2010 in 1-9 months is 552.8 ten thousand tons and the same ratio is increased by 28.23%. Meanwhile, as the quality requirements of consumers on the aspects of environmental protection, health, durability and the like of products are continuously improved, the quality level of the products is continuously improved while the yield of plastic pipelines in China is increased, the technical progress of the industry is continuously accelerated, brand scale enterprises are continuously increased, new materials and new structure varieties are continuously emerged, advanced system design concepts are infinite, the functions of the products are more obvious, and the application fields are further widened. Analysis shows that the market share of Chinese plastic pipelines currently exceeds 30 percent of all pipelines.

The PSP steel-plastic composite pressure pipe in the prior art adopts the mode that the inner layer of the PPR pipe is coated with the silver ion antibacterial agent to realize the antibacterial action, has the friction loss in the use process due to the silver ion antibacterial agent coating, thereby influencing the antibacterial effect and the service life of the PSP steel-plastic composite pressure pipe, and being easy to age on the outdoor PPR layer, and the oxidation phenomenon can appear on the steel belt layer inside after long-time use, thereby influencing the overall strength. In addition, the proportion of the PPR layer, the thickness of the steel belt layer and the outer diameter of the pipeline engineering of the PSP steel-plastic composite pressure pipe in the prior art is unscientific, so that the pipeline strength can not meet the requirement or the PPR layer expands and deforms.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a compound pressure pipe is moulded to PSP steel with antibacterial function to solve among the prior art PSP steel and mould compound pressure pipe and when long-term the use antibacterial effect is unsatisfactory, the life-span is short and install the problem of easily ageing outdoors. The utility model adopts the following technical scheme:

the utility model provides a compound pressure pipe is moulded to PSP steel with antibacterial function, includes middle steel tape layer, the steel tape in situ, the outside bonds respectively and has interior antibiotic PPR layer and hinder the oxygen layer, hinders the oxygen layer outside and bonds and have outer PPR layer, and outer PPR layer outside scribbles the protection skin.

Further, the oxygen barrier layer is an EVOH resin layer or an ethylene-vinyl alcohol copolymer.

Further, the protective outer layer is a Teflon coating.

Furthermore, the engineering outer diameter of the composite pressure pipe is 50mm, the thickness of the inner antibacterial PPR layer is 1.4mm, the thickness of the outer PPR layer is 1.5mm, and the thickness of the steel belt layer is not less than 0.5 mm.
