Abstract
The utility model relates to the field of pipelines, in particular to a PPR (Polypropylene Random) tube provided with a reinforced metal layer. The PPR tube provided with the reinforced metal layer comprises a tube body, wherein the tube body comprises a PPR inner tube layer and a PPR outer tube layer; and a metal layer is formed between the PPR inner tube layer and the PPR outer tube layer, and is made of stainless steel. The PPR tube has the advantages of increase in the strength, hardness and rigidity, reduction in the line expansion and reduction in aging.
Description
Technical field
The utility model relates to the pipeline field, is specifically related to a kind of PPR pipe.
Background technique
The advantage that atactic copolymerized polypropene (PPR) pipe is light except the quality that possesses general plastic tube, thermal conductivity is low, thermal loss is little, easy for installation, also have the advantage of nontoxic, health, better heat-resisting and heat preservation energy-saving, long service life, thereby progressively be extensive use of.Yet because the material behavior of PPR pipe self makes to be not so good as metallic conduit aspect intensity and hardness, thereby obtains restriction in some applications.
The model utility content
The purpose of this utility model is, provides a kind of PPR pipe that is provided with enhancement mode metal layer, to address the above problem.
The technical problem that the utility model solves can realize by the following technical solutions:
Be provided with the PPR pipe of enhancement mode metal layer, comprise a body, it is characterized in that, described body comprises pipe layer, a PPR external tube layer in the PPR (atactic copolymerized polypropene), is provided with a metal layer between pipe layer and the described PPR external tube layer in the described PPR.
Be provided with a metal layer between pipe layer and the PPR external tube layer in the PPR of the present utility model, have the intensity of enhancing, increase hardness and rigidity, reduce advantages such as line expands, reduces to wear out.
Described metal layer adopts the metal layer of aluminum or steel.The metal layer that described metal layer preferably adopts stainless steel to make.Be beneficial to the metal layer that stainless steel makes and solve the shortcoming that the metal layer that adopts aluminum has the rigidity deficiency.
Be provided with an adhesive layer between described PPR external tube layer and the described metal layer, also be provided with an adhesive layer between pipe layer and the described metal layer in the described PPR, the adhesive layer that described adhesive layer adopts hot melt adhesive to make.Be to adopt the hot melt adhesive bonding in described PPR external tube layer, metal layer, the PPR between the pipe layer.Order is followed successively by from outside to inside: pipe layer in PPR external tube layer, adhesive layer, metal layer, adhesive layer, the PPR.
The inside of one deck at least of pipe layer, PPR external tube layer also is provided with enhancement layer in the described PPR, and described enhancement layer adopts glass fibre to make, in order to further strengthen intensity, reduce line and expand.Described glass fibre can make chopped strand, also can be the long fiber of cutting.
At least one place of the internal surface of pipe layer also is provided with an oxidation prevention layer in the outer surface of described PPR external tube layer and the described PPR, the oxidation prevention layer that described oxidation prevention layer adopts EVOH or PVDC to make.Can reduce the transmittance of oxygen effectively, on the one hand can suppress the pipe fitting wall bacteria, algae grows, oxidation rate that on the other hand can pipe fitting prolongs life-span of pipe fitting.
Hot melt adhesive is to be Main Ingredients and Appearance with thermoplastic resin or thermoplastic elastomer (TPE), add compositions such as plasticizing agent, tackifying resin, antioxidant, fire retardant and filler, the not solvent-laden solid adhesive agent of making through melting mixing, wherein, EVA (ethene and acetate ethylene copolymer) hot melt adhesive has the easy advantage of preparation method.Described hot melt adhesive adopts the EVA hot melt adhesive.
Beneficial effect: owing to adopt above technological scheme, the utlity model has the advantage that strengthens intensity, increases hardness and rigidity, reduces the line expansion, reduces to wear out.
