Description

At the continuous process units of steel-plastic composite pipe that hole Steel Skeleton inner and outer surface coated with adhesive is arranged

Technical field:

The utility model relates to a kind of metal frame with hole and makes to strengthen body, extrude the process units that composite materials forms the plastic composite pipe that metal frame strengthens at the skeleton inner and outer surface, particularly be the producer device of before composite materials is extruded on the surface of pertusate metal frame, extruding the plastic composite pipe of coated with adhesive layer in advance.

Background technique:

Existing with pertusate metal frame do enhancing body, on this skeleton, extrude composite polymeric materials and method and apparatus and the corresponding patent that skeleton coats the production technology that forms steel-plastic composite pipe had many reports and open as continuum, as B. P. GB2255,148A92.10.28, Chinese patent application numbers 94104509.9, application number 98119383.8, application 99232026.7 application number 99232162.X and 99232214.6 application numbers, 99114790.1 application numbers 00222720.7 and 00132035.1 application number, 99112221.6 application numbers 01113962.5.

These disclosed technological schemes are that steel plate with hole with holes is through being curled into cartridge type longitudinally and being welded as the cartridge type metal frame, or helical coil coiled cartridge type and be welded as the cartridge type metal frame, or spiral twines the broadwise reinforcing bar on the warp-wise reinforcing bar that vertically distributes, through being welded as the cartridge type metal frame, or vertical distribution warp-wise reinforcing bar is through being welded as the cartridge type metal frame on the broadwise reinforcing bar periphery that spiral twines, metal frame is pushed or draws in the compound die head of the polymer that molten plastic runner and forming cavity are arranged or forming cavity mould that is connected with plastic extruder, and the hole that the polymer continuum of fusion passes metal frame coats at the inner and outer surface formation internal and external layer of metal frame and with skeleton.Pass through cooling and shaping, just produced the composite metal plastic pipe that metal frame strengthens the tube wall that is coated with metal frame.This pipeline promptly has the higher bearing capacity of metallic conduit, because of inside and outside wall with plastics and the hole by metal frame inside and outside wall is connected as a single entity again, advantages of good anticorrosion performance and pipeline switching performance are arranged, with metallic conduit and pure plastic pipe channel ratio, comprehensive performance is arranged, obtaining on chemical industry, oil transportation, delivery of fuel gas, discharge pressure and Korrosionsmedium widely and use, is a kind of structural preferably multiple tube.But, the personnel that possess this field professional technique know, the surface of metal frame such as steel and aluminium is a polar surfaces, and stronger polymer such as the polyethylene of antiseptic power, the interface of polyolefine materials such as polypropylene is an apolar surfaces, at polymer fusion clad metal skeleton, behind cooling and shaping, the interface of metal frame and polymer continuum in fact only is a kind of coating, the interface do not have real affinity promptly bonding form one, should not become real composite structure composite material in other words, therefore also influenced the wider application of this pipeline, even there is aggressive medium to go into metal frame by the metal frame of the pipe end of cut-out and the contacting permeation of polymer, the corroding metal skeleton, and then wear out the plastic outer layer on the metal frame and danger that pipeline was lost efficacy.In order to address this problem, people have to adopt with maleic anhydride or acrylic ester grafted polymer and make the polymer continuum of clad metal skeleton, or adopt and can make the polymer connecting body with other polymer material of metal surface affinity.But or costing an arm and a leg of this binary or ternary polymerization with the material of metal material surface affinity or bonding, or do not reach the usability of polypropylene or this material of polyethylene, general engineering can not be taked these schemes with pipe.People have adopted comparatively economic scheme again for this reason, the ethene of the weight ratio with 15 at least 30% and maleic anhydride or acrylic ester grafted polymer and polyethylene or the polypropylene blending modified continuum that is used as use, though this scheme can produce affinity and promptly bond with the surface of metal frame, but because the ratio that adds is still higher, still influence the serviceability temperature and the corrosion resistance of this pipeline, particularly the cost of polymer continuum is still higher, and pipeline is lacked competitiveness and can not be enlarged application area.Particularly caliber is bigger, and the pipeline of thickness of pipe wall is big because of adding the graft polymer amount, and the cost height more can't be competed with other pipeline.Therefore need that more economical feasible scheme solves the metal frame of metallic skeleton reinforced composite plastic pipe and the interface affinity of polymer continuum is an adhesion problem.Only having the patent of application number 99112221.6 to mention in method in the above-mentioned patent utilizes the steel plate that is compounded with organic matter layer earlier to make the method that the tubular metal frame is extruded the composition polymer continuum again, and the method that before extruding the composition polymer continuum, earlier the tubular metal frame is added composite bed or spraying organic substance composite bed, but just how to carry out or do not finish not disclosure with which kind of device and which kind of organic substance composite bed, more do not mention how processing and coated with adhesive, and how it to be removed apply to coat pertusate metal frame, make the polymer continuum by adhesive layer with skeleton bond compound the be play-by-play of composite material, particularly Zhuan Zhi report.

Prior art is relevant at steel pipe or aluminum pipe, extrude the coated polymer layer on the steel pipe inside and outside wall behind the coated with adhesive layer again or will form the report of composite pipe after polymer production tube and the adhesive layer bonding, but this composite pipe is different from the composite pipe of pertusate metal frame and polymer, this with do not have the compound composite pipe of metal tube of hole, though bearing capacity is fine, the pipeline corrosion protection ability is also strong, but the coefficient of linear expansion of polymeric layer and metal tube differs from an order of magnitude, when used by thermal environment or used by cold environment, polymeric layer can have significantly than the metallic conduit in mesosphere and elongates or shortens, the metallic conduit that makes pipe end is exposed and make anticorrosion inefficacy, pipe fitting connects with only depending on outer very thin one layer of polymeric being connected of pipeline in addition, no matter be that hot melt connects or mechanical grip connects, all there is not join strength, bearing capacity and pipeline bearing capacity are incoordinate for pipe network, the joint is the weakest and not durable, dangerous, this pipeline is because the coefficient of linear expansion difference practical application effect of the varying number level of different materials and bad.

But the steel-plastic composite pipe of pertusate metal frame, because of the polymer-coated metal skeleton, polymer utilizes the hole on the skeleton to form inside and outside wall, the internal and external layer of the polymer on the actual tube wall is connected as a single entity by the hole riveted joint, when this polymer internal and external layer that is pinned by the hole of skeleton uses under hot-cool environment, the coefficient of linear expansion of coefficient of linear expansion and metal frame is the same order of magnitude, this is the very important performance that this pipeline obtains, this steel-plastic composite pipe does not have the problem of the different coefficient of linear expansion of compound polymeric layer of above-mentioned the sort of and the metal tube that does not have hole and metal tube, and this performance is in control widely this kind and uses.Particularly the polymer of skeleton internal and external layer is one by the hole riveted joint of skeleton, when pipeline is connected by the pipe fitting hot melt, the intensity of joint is not only to be born by outer layer copolymer, but connect as one by polymer in skin and the hole and internal layer polymer, the intensity of metal frame participates in addition, this join strength is equal to the intensity of this steel-plastic composite pipe fully, high more a lot of than the metal composite pipe pipe network join strength that does not have hole, combination property and antiseptic property might as well be a lot, though increase plyability with polymer so the metal composite pipe of two kinds of different structures all exists in metal surface coated with adhesive layer, but the structure difference of pipe, method difference and process units are more inequality, because of the adhesive coated that the hole skeleton is arranged is passed hole and metal surface bonding and coating by Bond.The metal tube that does not have hole is respectively at the inside and outside wall coated with adhesive layer composition polymer layer of metal tube, and internal layer and outer the separation by metal tube become one.
