Abstract
The utility model discloses a reinforced polyethylene plastic composite pipe of steel wire gauze, including polyethylene inner plastic pipe, polyethylene inner plastic pipe is equipped with the polyurethane layer outward, polyurethane in situ portion is equipped with plastic -coated wire net enhancement layer, the polyurethane layer outside is equipped with the glass fiber layer, the glass fiber layer forms for the winding of glass fiber net cloth, polyethylene inner plastic pipe's internal surface is equipped with the composite plastic film layer, the composite plastic film layer is in for solidification polyester layer on the polyethylene inner plastic pipe and nylon layer's curtain coating coextrusion film, the utility model has the advantages of: intensity is high, and corrosion -resistant, the ageing resistance has prolonged life, has improved product quality.
Description
Technical field
This utility model relates to a kind of plastic pipe, specifically a kind of steel wire enhanced polyethylene plastic composite pipe, belongs to plastic pipe field.
Background technology
Steel-plastics composite pipe has stronger external force resistance destructive characteristics, is effectively improved the service life of pipeline, and extend pipeline is excused from a college course the phase, decreases the leakage of pipeline.Steel-plastics composite pipe is the favorable substitutes of steel conduit and nonmetal pipeline, has broad application prospects at the aspect such as oil-gas gathering and transportation and sewage transport.The Chinese utility model patent of entitled " a kind of steel wire enhanced polyethylene plastic composite pipe " Application No. " 201320727165.X " discloses a kind of steel wire enhanced polyethylene plastic composite pipe, multiple tube is followed successively by plastic inner pipe layer from inside to outside, Clad Steel silk screen enhancement layer, polyethylene adhesive-layer, plastic outer tube layer, Clad Steel silk screen enhancement layer is wrapped in plastic inner pipe layer outer surface, Clad Steel silk screen enhancement layer outer surface arranges layer of polyethylene adhesive-layer, at polyethylene adhesive-layer outer surface plastic covering external tube layer, use the mode of electric heat welding again, make to be formed between plastic inner pipe layer and polyethylene adhesive-layer fused layer A, fused layer B is formed between polyethylene adhesive-layer and plastic outer tube layer, Clad Steel silk screen enhancement layer merges in polyethylene adhesive-layer, each layer is combined closely becomes an entirety.But, this product structure intensity is relatively low, and inside and outside wall is the most damaged, and antiageing effect is poor, reduces service life.
Utility model content
In order to solve the problems referred to above, this utility model devises a kind of steel wire enhanced polyethylene plastic composite pipe, and intensity is high, corrosion-resistant, and aging resistance extends service life, improves product quality.
The technical solution of the utility model is:
A kind of steel wire enhanced polyethylene plastic composite pipe, including vinyon inner tube, described vinyon inner tube is externally provided with layer of polyurethane, Clad Steel silk screen enhancement layer it is provided with inside described layer of polyurethane, it is provided with glass layer outside described layer of polyurethane, described glass layer is that fiberglass gridding cloth is entwined, so that product has higher structural strength, and anticorrosion effect is good；The inner surface of described vinyon inner tube is provided with compound plastic film layer；Described compound plastic film layer is the curtain coating co-extrusion film of polyester layer and the nylon layer being solidificated in described vinyon inner tube, compound plastic film layer is in addition to combining with vinyon inner tube and bearing the hydraulic pressure stress with minimizing tubing, the combination between polyester layer and nylon layer can also be made more firm, fit more uniform, material stress is more uniform, is of value to drawing and forming；By using curtain coating co-extrusion mode, it is not necessary to other adhesive layer, reduce the integral thickness of compound plastic film so that compound plastic film can be made the thinnest, the lightest after increasing polyester layer；There is higher impact strength and folding quality.
Further, being provided with oxidation prevention layer outside described glass layer, described oxidation prevention layer uses EVOH high barrier material to make, it is possible to effectively starvation, prevents oxygen from extending into steel wire further, can effectively prevent steel wire from aoxidizing, improve the service life of multiple tube.
Further, the outside of described oxidation prevention layer is provided with nano-ceramic particle layer, improves the structural strength of product, the most easy to wear, extends service life.
The utility model has the advantage of: intensity is high, corrosion-resistant, aging resistance extends service life, improves product quality.
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
Hereinafter preferred embodiment of the present utility model is illustrated, it will be appreciated that preferred embodiment described herein is merely to illustrate and explains this utility model, be not used to limit this utility model.
Embodiment 1
As shown in Figure 1, a kind of steel wire enhanced polyethylene plastic composite pipe, including vinyon inner tube 1, described vinyon inner tube 1 is externally provided with layer of polyurethane 2, described layer of polyurethane 2 is internal is provided with Clad Steel silk screen enhancement layer 3, is provided with glass layer 5 outside described layer of polyurethane 2, and described glass layer 5 is entwined for fiberglass gridding cloth, so that product has higher structural strength, and anticorrosion effect is good；The inner surface of described vinyon inner tube 1 is provided with compound plastic film layer 4；Preferably, described compound plastic film layer 4 is the curtain coating co-extrusion film of polyester layer (PET) and the nylon layer (PA) being solidificated in described vinyon inner tube, compound plastic film layer is in addition to combining with vinyon inner tube and bearing the hydraulic pressure stress with minimizing tubing, the combination between polyester layer (PET) and nylon layer (PA) can also be made more firm, fit more uniform, material stress is more uniform, is of value to drawing and forming；By using curtain coating co-extrusion mode, it is not necessary to other adhesive layer, reduce the integral thickness of compound plastic film so that compound plastic film can be made the thinnest, the lightest after increasing polyester layer (PET)；There is higher impact strength and folding quality.
Wherein, being provided with oxidation prevention layer 6 outside described glass layer 5, described oxidation prevention layer 6 uses EVOH high barrier material to make, it is possible to effectively starvation, prevents oxygen from extending into steel wire further, can effectively prevent steel wire from aoxidizing, improve the service life of multiple tube.The outside of described oxidation prevention layer 6 is additionally provided with nano-ceramic particle layer, improves the structural strength of product, the most easy to wear, extends service life.
