Abstract
The utility model relates to a composite pipe, in particular to a weathering-resistant and oxygen-resistant PPR composite pipe used for the water supply in the construction field. The composite pipe is provided with a pipe body. The pipe body is provided with an internal chamber, a first nozzle and a second nozzle. The first nozzle is communicated with the second nozzle via the internal chamber. The composite pipe is characterized in that a straight-through pipe body consists of a fluorocarbon resin layer, an oxygen-resistant rubber layer and a random polypropylene (PPR) layer; the oxygen-resistant adhesive layer is arranged between the fluorocarbon resin layer and the random polypropylene (PPR) layer to bond the two layers; the fluorocarbon resin layer is bare on the external surface of the pipe body. The product is provided with the good weather-resistant performance, the good oxygen-resistant effect, the low production cost, and the long service life, and is simple in the manufacture, widely applicable and fit for the large-scale industrial production.
Description
Technical field
The utility model relates to a kind of composite pipe, especially a kind of weather-proof oxygen barrier PPR composite pipe of building water supply field use.
Background technique
Along with the raising of living standards of the people and wideling popularize of national policy, the PPR feedwater piping has obtained using widely in the building water supply field of China because of plurality of advantages such as its good wholesomeness, temperature tolerance, toughness, resistance to pressures.But the objective fact that also has the printing opacity oxygen flow simultaneously impels bacterium and algae to grow (producing green paint), influences water quality, causes line clogging when serious; Its weatherability is relatively poor relatively simultaneously, must take protective measure when being used for outdoor mounted, otherwise its working life and withstand voltage properties will be affected all.At the oxygen flow problem, domestic production producer released one after another PPR aluminium-plastic composite pipe and PPR stable state pipe, these technology have solved the oxygen flow problem to a certain extent aspect tubing, but the problem of weatherability difference is not resolved yet, and the cost of production height, waste product can't be recycled once more.PPR scratches and produce Electrostatic Absorption when mounted easily in addition, and is dirty because of dust absorption after use a period of time, influences product appearance.Therefore, this defective that existing PPR tubing exists is necessary to improve.
The model utility content
The purpose of this utility model provides the PPR composite pipe that a kind of weather resistance is good, oxygen barrier is effective, cost of production is low.
A kind of weather-proof oxygen barrier PPR composite pipe of the present utility model has body, described body has inner cavity, first mouth of pipe and second mouth of pipe, described first mouth of pipe and second mouth of pipe are connected by described inner cavity, it is characterized in that described body is made of fluorocarbon resin layer, oxygen barrier glue-line and atactic copolymerized polypropene layer, described oxygen barrier glue-line is between fluorocarbon resin layer and atactic copolymerized polypropene layer and with the two phase adhesion, and described fluorocarbon resin layer is exposed to outer surface of tube body.
The FC resin layer that fluorocarbon resin layer described in the composite pipe of the present utility model promptly is commonly referred to, described FC resin layer can adopt the commercially available prod, as: the FC-S300B type FC (fluorocarbon resin) that Daikin is produced.Described fluorocarbon resin layer just can become water-wetted surface after using very short time out of doors, has good anti-rainprint pollution capacity, low static, easy to clean, makes the weather resistance of composite pipe better, and in addition, fluorocarbon resin layer hardness height can reach more than the 4H, is difficult for scratching.The PPR layer that described atactic copolymerized polypropene layer promptly is commonly referred to can adopt the commercially available prod, as: the PPR that Finland Borealis or Korea S Da Lin produce etc.Described oxygen barrier glue-line promptly has the macromolecule composite layer of oxygen barrier performance, can serve as by commercially available oxygen barrier glue material, generally also can adopt and contain EVA (ethylene-vinyl acetate copolymer), EVOH (ethylene-vinyl alcohol copolymer) or acrylate and derivative thereof serve as, be characterized in that the macromolecule composite layer can accomplish complete oxygen barrier, avoided bacterium and algae in the pipeline to grow, guaranteed that water quality is not contaminated, and, the surface that the pure PPR of moulding layer is contacted with the macromolecule composite layer produces active group, it is combined closely with the macromolecule composite layer, and the sub-composite layer of macromolecule also can finely combine with C-F key in the fluorocarbon resin layer, the layer that makes whole composite pipe with layer between peeling strength very high, thereby prolonged working life of composite pipe, guaranteed quality of product.Composite pipe performance of the present utility model is equivalent to similar PPR five-layer co-squeezing pipeline, but cost of production is lower than similar PPR five-layer co-squeezing pipeline, and the cost performance height has great market value.
Manufacture of the present utility model adopts prior art, can be earlier with atactic copolymerized polypropene layer (PPR layer) extruding and moulding, spray the oxygen barrier glue-line then, thereby spray the fluorocarbon resin layer at last and constitute above-mentioned composite pipe, certainly in case of necessity, also can distinguish earlier and make fluorocarbon resin layer, oxygen barrier glue-line and atactic copolymerized polypropene layer separately, by the later stage operation it being combined then constitutes above-mentioned composite pipe.
A kind of weather-proof oxygen barrier PPR composite pipe described in the utility model, its structure can be that the medial axis of described first mouth of pipe overlaps with the medial axis of second mouth of pipe, and promptly described body is straight-through body.Can certainly be that intersect the medial axis of described first mouth of pipe and the medial axis of second mouth of pipe, described intersecting also comprises the situation that intersects vertically.
Compared with the aforementioned existing similar products, PPR composite pipe weather resistance of the present utility model is good, oxygen barrier is effective, cost of production is low, can effectively prolong life of product, make simple and applied widely, suitable large-scale industrial production.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
