Description
Technical field:
What the present invention relates to is a kind of composite pipe, particularly be a kind of plastics of thermal-isolation impact-resistant and the composite pipe of glass fibre reinforced plastics.
Background technique:
Polymer matrix composites, particularly with poly-resin or epoxy resin serve as the basis with the glass fiber reinforced plastics composite material of alkali-free glass fiber combination in the production of pipeline with use and be tending towards ripe, and accounted for a very big ratio of total application quantity of pipeline.The pipeline of this pure glass fibre reinforced plastics and traditional steel pipe, the metal tube ratio has good antiseptic property, simultaneously good intensity is arranged also, and certain heat resistance is also arranged.Therefore in engineering, widelyd popularize and used.
Glass Steel Tube and pure plastic pipe such as polyvinyl chloride pipe, the PE pipe, the polypropylene tube ratio, higher intensity is arranged, rigidity and temperature resistant capability, but leakage proof and not enough to the antiseptic power of some solvent, impact resistance is not enough, so people have invented with pure plastic pipe and glass fibre reinforced plastics composite methods and have produced composite pipe, wherein with publication number CN1111736A, " pipe material made from plastic alloy double-composite modified reinforced fibre glass and manufacture method thereof " is representative, it is exactly the compound typical case of pure plastic pipe and glass fibre reinforced plastics, to with filament winding process in the inner tube outside be that the compound material of matrix and alkali-free glass fiber forms the mesosphere with alkyd resin or epoxy resin mainly, extrude compound and internal layer identical materials coated with glass fibre reinforced plastics in the outside, mesosphere, make it shock resistance.This pipe has overcome single thermoplastic pipes insufficient strength, the not enough shortcoming of pressure-bearing during high temperature, but because of pipe in doing with anticorrosion chlorinated polynvinyl chloride (CPVC) good, that leakage proof is good, overcome Glass Steel Tube again because of easy to leak, and reduced shortcoming anticorrosion, waterproof ability; In the outer compound chlorinated polynvinyl chloride (CPVC) of extruding the same material of one deck and internal layer of glass fibre reinforced plastics, not impact-resistant glass fibre reinforced plastics can be protected again.
But this pipe is in the construction of oil, chemical industry, combustion gas, oil field, engineering such as pour water and using, reality runs into many unvanquishable problems again, such as: actual between inner tube and the mesosphere because of the material difference, do not have to adopt the adhesive layer that is fit to, two bed boundarys are closely connected, perhaps the pipe end face to two bed boundarys is provided with encapsulation process, in the pipe network practical application, fed sheet of a media easily from the interface seepage between centre and the inner tube, finally destroys the mesosphere, and pipeline was lost efficacy; In oil extraction transportation plumber journey is used, secondary or tertiary oil recovery are easily freezing because of moisture content height in the oil-water ratio, in the time of need being incubated pipeline of oil production, or heat and carry viscous crude to strengthen finding that above-mentioned this composite modified glass steel pipeline insulating power is not enough when insulation prevents viscous crude cooling plugging pipe, if increase Glass Steel Tube thickness increases insulating power the pipeline cost is raise, thereby need more economical effective insulation measure; Inner tube adopts haloflex not enough to the pressure-bearing antiseptic power that conveying is higher than the serious chemical mediator of the thermal mediums of 100 degree or thermal oxidation; Also some engineerings is used, and it is bigger to manage hot and cold alternate, and pipe expands with heat and contract with cold seriously, so the interconnection technique of pipe not only will be rigidly connected, and the connection of retractable and flexible joint socket also should be arranged; The conveying of the corrosivity thermal medium that particularly pressure rating is high, higher to the seal request at inner tube and interface, mesosphere, higher to the end face seal requirement of pipeline; Above-mentioned Environmental Conditions requires also higher with engineering to the bearing capacity that pipeline is connected, majority binding metal flange on glass fibre reinforced plastics adopts bolt and is threaded for this reason, though glass fibre reinforced plastics intensity is high, but easily causes stress to concentrate at metal flange and glass fibre reinforced plastics joint, easy-rupturing lost efficacy pipe network.
Summary of the invention:
The objective of the invention is in order to overcome above deficiency, provide a kind of thermal insulation property, shock resistance good, the intensity height, good toughness, anti-fracture, switching performance is good, the plastics of the thermal-isolation impact-resistant of long service life and the composite pipe of glass fibre reinforced plastics.
The object of the present invention is achieved like this:
The plastics of thermal-isolation impact-resistant of the present invention and the composite pipe of glass fibre reinforced plastics comprise the inner plastic that anti-corrosion leak-proof leaks, be coated on the adhesive layer on the inner plastic, be coated on the compound enhancement layer of resin base glass fibre reinforced plastics of adhesive layer periphery, be coated on the thermal-isolation impact-resistant foaming structure layer of compound enhancement layer periphery, there is connection boss or the flange that is connected with compound enhancement layer periphery at the composite pipe two ends, and at least one end connects on the boss screw thread.
Above-mentioned inner plastic adopts polyolefin, polypropylene, chlorinated polynvinyl chloride (CPVC), plastic alloy to make, thermal-isolation impact-resistant foaming layer employing polypropylene and copolymer thereof or polyethylene or PVC are made, and adopt different materials to do internal layer and outer field foaming layer respectively when the fed sheet of a media difference, when the temperature difference is different with environment.
Above-mentioned foaming layer outer surface is the close layer of matter.
Above-mentioned connection boss or flange adopt resin base glass fibre reinforced plastics or metal-base composites or metallic material to make.
Above-mentioned connection boss or flange and compound enhancement layer be one or with compound enhancement layer bonding connection, connecting boss can connect when pipeline construction or be bonded on the compound enhancement layer.
At least one end of above-mentioned composite pipe has the extended pipeline of caliber to connect joint socket.
Above-mentioned inner plastic two ends are stretched out the composite pipe turnover respectively and have been formed the pipeline end face.
The pipeline end face of the shutoff internal layer that the respectively useful adhering resin in above-mentioned composite pipe two ends forms, adhesives layer, compound enhancement layer.
Ultraviolet radiation resisting, anti-aging or fire-retardant auxiliary agent are arranged in the above-mentioned foaming layer,, make tubing environment use down in the open as carbon black or bromide.
The present invention has adopted inner plastic and compound enhancement layer of resin glass fibre reinforced plastics and foaming layer, and thermal insulation property, shock resistance are good, the intensity height, and good toughness, anti-fracture, switching performance is good, long service life, using scope is wide.
