Description
Technical field
This utility model relates to a kind of plastic pipe, specifically a kind of polyethylene gf Winding Composite Pipes, 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 " polyethylene glass winding structure wall pipe " Application No. " 201420152572.7 " discloses a kind of polyethylene glass winding structure wall pipe, it is made up of inner wall layer and outer wall layer, its inner wall layer is to be spirally wound on drum die by adding the compound material strip that glass material strip formed in the middle of upper and lower lamellar polyethylene tape, and each adjacent composite strip edge the most mutually overlaps and merges the continuous solid wall pipe formed；Outer wall layer is helically wound around the evagination reinforcement that inner wall layer outer surface formed and constitutes by covering glass material strip in the middle of tubular polyethylene band outer, interior, and this evagination reinforcement spiral cross-pressure overlap joint in each adjacent composite strip edge of inner wall layer melts commissure.But, this product structure intensity is relatively low, and inside and outside wall is the most damaged, connects insecure, 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 polyethylene gf Winding Composite Pipes, 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 polyethylene gf Winding Composite Pipes, including vinyon inner tube, described vinyon inner tube is externally provided with layer of polyurethane, fiber reinforcement layer it is provided with inside described layer of polyurethane, described fiber reinforcement layer is the mesh skeleton structure that macromolecule carbon cellosilk left-and-right spiral is Wrapping formed, use macromolecule carbon fiber to substitute original coppered steel wire and manufacture casing play, the weight of multiple tube is reduced on the basis of maintaining original performance, oxidation prevention layer is had outside described layer of polyurethane, described oxidation prevention layer uses EVOH high barrier material to make, can effective starvation, prevent 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 is provided with continuous fiber prepreg tape, described continuous fiber prepreg tape is formed by laser action welding with the multilamellar continuous fiber prepreg tape of longitudinally staggered winding by hoop, improve the compression resistance of product and wear-resistant effect, extend service life, improve product quality.
Described continuous fiber is the one in glass fibre, basalt fibre or carbon fiber.
Wherein, described vinyon inner tube is the continuous solid wall pipe formed by upper lamellar polyethylene tape, bottom sheet shaped polyethylene band and middle glass material strip spiral winding, and each adjacent ribbons edge the most mutually overlaps fusion；Eliminate original polyethylene backbone pipe, use glass band, it is ensured that the plastic inner pipe centre of form, away from height, reduces product cost.
Further, the inner surface of described vinyon inner tube is provided with compound plastic film layer；Preferably, 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, polyester layer can also be made more firm with the combination of nylon interlayer, 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.
It addition, be additionally provided with epoxy layer and ASA coating between described vinyon inner tube and described compound plastic film layer；Described epoxy layer is epoxy resin, and described epoxy layer is located between ASA coating and vinyon inner tube, can operation at bad environments, and length in service life, serviceability are good.
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.
