Technical field
The utility model relates to composite pipe, the self-cleaning PPR composite pipe of specifically a kind of anticorrosion oxygen barrier.
Background technique
The PPR pipe is because of advantages such as its good wholesomeness, toughness, resistance to pressures, is widely used at the building field of China.The nontoxic salubrity requirement of PPR plastic tube itself, but the PPR plastic tube does not have self-cleaning function and kills the bacterium function, under this specific environment of domestic water, the backward technology of contaminated water source, waterworks and pipe network thereof outmoded unreasonable, after the PPR plastic water pipe uses a period of time, the inner tube wall secondary pollution is serious, is the ground of growing of bacterium, Legionella, the serious threat health.Simultaneously also exist weather resistance poor, can not blocking oxygen, easily cause microorganism/algae to grow in the pipe, cause that water pollutes in the pipe.Therefore this defective that existing P PR tubing exists is necessary to improve.
The model utility content
(1) technical problem that will solve
The purpose of this utility model is the defective that exists at prior art, provides a kind of anticorrosion oxygen barrier self-cleaning PPR composite pipe, has solved the problem of the seriously polluted breed bacteria that the composite pipe of prior art exists.
(2) technological scheme
The technological scheme that its technical problem that solves the utility model adopts is: the self-cleaning PPR composite pipe of a kind of anticorrosion oxygen barrier, its structure comprise one-time formed interior China and foreign countries three-decker.
China and foreign countries' three-decker is respectively the internal layer of modified polyvinilidene fluoride formation, macromolecule compound adhesive middle level, the atactic copolymerized polypropene skin with oxygen barrier function in described.
Internal layer, atactic copolymerized polypropene skin that described modified polyvinilidene fluoride constitutes bond together mutually by the macromolecule compound adhesive middle level with oxygen barrier function and become one.
Serve as with having oxygen barrier function glue material in macromolecule compound adhesive middle level with oxygen barrier function, employing generally contains EVA (ethylene-vinyl acetate copolymer), EVOH (ethylene-vinyl alcohol copolymer) or acrylate and derivative thereof etc. serve as, and is characterized in that the macromolecule composite layer can starvation.
(3) beneficial effect
The self-cleaning PPR composite pipe of a kind of anticorrosion oxygen barrier of the present utility model is compared with prior art, has following beneficial effect:
Polyvinylidene fluoride described in the PPR composite pipe that the utility model relates to is a polyvinylidene fluoride resin after the modification, and described polyvinylidene fluoride resin also can adopt the commercially available prod, as: A Kema produces
The ADX resin.Described polyvinylidene fluoride modified fluororesin has outstanding self-cleaning function and remarkable corrosion-resistant and ageing-resistant function, can prevent effectively that tube wall incrustation from really accomplishing not have dirt and never fouling, can prevent effectively that also bacterium and algae from adhering at tube wall, bacterium of thoroughly stopping and algae are caused water pollution once again owing to adhering to and growing.Described atactic copolymerized polypropene material layer claims the PPR layer usually, can adopt the commercially available prod, the PPR that produces as Korea S LG chemistry or Finland Borealis etc.Described oxygen barrier glue-line promptly has the macromolecule composite layer of oxygen barrier function, available commercially available oxygen barrier glue material serves as, usually adopt down and contain EVA (ethylene-vinyl acetate copolymer), EVOH (ethylene-vinyl alcohol copolymer) or acrylate and derivative thereof etc. serve as, be characterized in that the macromolecule composite layer can starvation, avoided interior bacterium of pipeline and algae to grow, guarantee that water quality is not contaminated, and the polyvinylidene fluoride layer of composite layer and modification has good cementability, interlaminar strength is very high, thereby has prolonged the working life of composite pipe, guarantee the quality of product.
Preparation method of the present utility model adopts prior art, adopt the three-layer co-extruded technology that goes out, once-through prepares described PPR composite pipe, compare with existing like product, PPR composite pipe of the present utility model, not only technology is simple, and composite pipe has corrosion resistance and good, the oxygen barrier performance is good and have outstanding self-cleaning function, be a kind of desirable hot and cold water tubing for building, product price ratio height has the very big market value of better application prospect.
