Description
Technical field
The present invention relates to a kind of plastic tube, more particularly to a kind of new steel mesh plastic composite pipe.
Background technology
Steel-plastic composite pressure pipe material be widely used in municipal buried water supply, build buried domestic water, buried fire water-supply,
Industrial wastewater discharge (pressure pipe), industrial acid-base solution and powder or slurry pipeline steel.The composite pipe species, domestic market is common
There are SRPE, two kinds of tubing of steel wire mesh frame plastic composite tube.
Existing steel frame-plastic polyethylene compound pipe（Structure such as patent No. CN98119383.8, entitled " netted reinforcing bar
Described in the manufacturing method and apparatus of the netted steel skeleton of frame-plastic composite pipe " Chinese invention patent) in manufacturing process, generally need
Steel wire is first fabricated to netted steel skeleton, netted steel skeleton is made up of tubing axial direction warp with ring parallel steel wire, Ran Houzai
Extrusion moulding is carried out on steel skeleton, in order to the steel wire for ensureing steel skeleton in extrusion process is indeformable, displacement, the warp of steel skeleton
Line is required for being welded and fixed in advance with each cross-contact point of parallel, and speed of production is too slow, inefficiency.In order that
Steel skeleton is in the centre of compound tube wall, will not deform and be partial to very much the outside or inner side of tube wall, then needs to pipe
Wall is thickeied, steel skeleton is made of thicker steel wire, so considerably increases the production cost of multiple tube.Due to steel wire and poly- second
Two kinds of materials of alkene plastics cannot be bonded naturally, the impact of the Fluid pressure of conveying in the rising-heat contracting-cold during use and pipeline,
Easily there is steel wire and plastics lamination problem in steel-plastics composite pipe, causes fluid seepage booster from pipe end, therefore pacify in construction
During dress, cut-out pipe end exposed steel wire need to remake processing injection or solder up ring, and encapsulation process is carried out to pipe end, prevent
Hidden leakage defect in the conveying of fluid stopping body.The construction technique complicated and time consumption of this sealed port, limits making for this kind of tubing
Use scope.
To overcome the shortcoming of above-mentioned patent No. CN98119383.8 tubing, domestic steel wire mesh frame plastic of having invented again is combined
Pipe (structure such as patent No. CN200420105205.8, entitled " the winding dress for preparing wire enhancing composite plastic pipe
Put " described in Chinese utility model patent).In manufacturing process, first with plastic extruder extruding pipe material inner layer plastic tube, it is being cooled to
The outer wall of the inner layer plastic tube of type winds the steel wire mesh frame of both forward and reverse directions chi structure, then extrudes hot melt adhesive special cladding institute
There is steel wire mesh frame, finally extrude one layer of plastic layer again in tubing outer layer, ectonexine plastics and steel are bonded using hot melt adhesive special
Silk screen casing play.This product structure, is prevented effectively from because the not be bonded integral hidden leakage defect of steel wire and plastics, and steel wire winding exist
Inner plastic pipe outer wall, not by steel wire mesh frame welding production rate limitation, production efficiency is greatly improved.Due to the tubing steel wire
Winding angle is 54 degree with tubing axial direction angle, can meet tubing and axially be balanced with the optimization of ring inward pressure.But, compared to upper
State patent No. CN98119383.8 tubing steel wire warps axially in parallel with tubing, tubing CN200420105205.8 axial directions with
Ring direction rigid is all substantially reduced, and is unfavorable for the working condition requirement that built on stilts installation is used, in built on stilts installation, flexible change
Shape.
The content of the invention
Deficiency the invention aims to solve prior art performance, there is provided it is high that one kind is provided simultaneously with intensity, and
It is avoided that two kinds of hidden danger of Material cladding layering, moreover it is possible to which wear-resisting internal layer, anti-corrosion, antibacterial, Zi Run are increased according to user's request selection
Sliding functional layer, to improve multiple tube wire and PUR bonding strength, embossing treatment, axial warp are made in steel wire outer surface
Steel wire crosspoint with ring parallel need not weld, and production efficiency is high.The present invention improves the new of universality energy for a kind of
Steel mesh plastic composite pipe.
Technical scheme is as follows：A kind of new steel mesh plastic composite pipe includes outer layer plastic layer and inner plastic
Layer, it is outer that the outer layer plastic layer is coated on inner plastic layer, it is characterised in that：The inner plastic layer is along multiple tube axial direction
Wire is provided with, one layer of PUR one is covered with the wire surface, between the outer layer plastic layer and inner plastic layer
One layer of PUR two is provided with, steel screen layer is provided with two layers of the PUR.
Used as further technical scheme of the invention, the steel screen layer is twined in unidirectional left-handed or unidirectional clockwise direction spiral
It is wound in two layers of PUR, steel wire and the axis angle of the steel screen layer are that 90 degree are less than more than 0 degree.
Used as further technical scheme of the invention, the steel screen layer left-handed is spirally wound in two-way with clockwise direction
In two layers of PUR, steel wire and the axis angle of the steel screen layer are that 90 degree are less than more than 0 degree.
Used as further technical scheme of the invention, the outer surface of the wire and steel screen layer is pressed with decorative pattern.
As further technical scheme of the invention, functional layer is provided with the inner plastic layer madial wall.
Used as further technical scheme of the invention, the wire is evenly distributed in ring, wire with it is tubular axle combined
The distance of heart line is equal.
As further technical scheme of the invention, distance of the wire on the inside of inner plastic layer more than its away from
With a distance from the outside of inner plastic layer.
Compared with prior art, beneficial effects of the present invention are as follows.
1st, the present invention improves the rigid of tubing due to using axial steel wire line and ring steel mesh structure simultaneously,
Flexural deformation is difficult, built on stilts installation applying working condition is more suitable for.
2nd, axial steel wire and ring winding steel wire are coated using PUR, solves the lamination problem of steel wire and plastics, disappeared
Except the hidden danger of pipe end seepage booster, it is to avoid numerous and diverse sealing treatment work.
3rd, after the embossing of steel wire outer surface, the long term adhesion strength of steel mesh and plastics is improve, is prevented effectively from composite pipe
In long-term use variation of ambient temperature make tubing expand with heat and contract with cold generation steel modeling layering.
4th, internal layer increases specific function layer, is capable of achieving pipeline and uses the wear-resisting of needs, anti-corrosion, antibacterial, the function of self-lubricating.
5th, axial steel wire line and ring wire are bonded using PUR and plastic layer, and steel wire crosspoint is solid without welding
Fixed, speed of production is greatly improved, and reduces production cost.
