Two-way enhancing sandwich layer high-voltage tube of continuous glass-fiber unidirectional prepreg tape and preparation method thereof
Technical field
The present invention relates to field of plastics manufacture, specially a kind of two-way enhancing sandwich layer high-voltage tube of continuous glass-fiber unidirectional prepreg tape And preparation method thereof.
Background technique
Continuous glass-fiber enhances thermoplastic pipe system, winds continuously unidirectional glass via hot melt wrapping machine circumferential direction melting and presoaks After band, have the characteristics that high heat resistance, high voltage, light weight, the burn into service life is not long, product quality is being greatly improved and is expanding On the basis of product purpose, the material utilization amount of manufacture pipeline can be greatly reduced by the high tensile of prepreg tape, realize low Cost, which makes continuous glass-fiber, enhances thermoplastic pipe system, is the direction of the following pipeline development.
The prepreg tape of this unidirectional circumferential hot melt winding, is to decompose axial direction by prepreg tape and tubing axial direction winding angle It with circumferential tensile stress and circumference stress, is calculated and is satisfied with by the laying tubing sandwich layer prepreg tape number of plies under normal conditions Composite pipe pipe fitting bears circumference stress both pumped (conveying) medium operating pressure requirements, the multiple tube of this preimpregnation band structure design enhancing It usually can satisfy in the pipe-line system of DN500mm diameter and pressure less than 2.0MPa, the reason is that the circumferential high-strength company of thin-walled Continuous fiber reinforcement pipeline, axial tensile strength are unable to satisfy major diameter and answer with axial tension caused by High Voltage pipe-line system The requirement that power increases at geometry grade.Such as a kind of continuous fiber reinforced thermoplastic compound tube of patent CN200810229501, the hair It is bright to disclose a kind of continuous fiber reinforced thermoplastic compound tube, belong to bimetallic tube technical field.This compound pipeline complex pipeline can be set Count at least three-decker, and in each layer all with thermoplastic resin be its matrix, with the continuous fiber of different content or its knit Object is its reinforcing material, and continuous fiber or its fabric are in a longitudinal fashion, canoe and weaving manner be laid with.This compound pipeline complex pipeline The performances such as shock resistance, ageing-resistant, temperature tolerance, weatherability can be improved, every layer of structural material of this compound pipeline complex pipeline is made Optimum optimization is obtained using with performance, can not only save a large amount of material, but also there is more excellent mechanical property and change Performance, but circumferential and axial stress cannot be improved simultaneously and use denaturation energy.A kind of continuous fibre of patent CN201310123058 The production method and wind of dimension winding enhancing thermoplastic pipe, the patent of invention provide a kind of continuous fiber winding enhancing heat The production method and wind of plastic tube, belong to pipeline production technical field.It solves existing continuous fiber winding and increases Heat-flash plastic tube be easy to cause the secondary damage of continuous fiber to generate filoplume or fracture during the preparation process, reduces continuous fiber Performance, the slickness of the pipeline outer wall of preparation and the problem that the robustness of pipeline is poor, strength character is unstable. A kind of high temperature resistant of CN201410038369, high pressure resistant enhancing thermoplastic composite tube and its process units disclosure of the invention are a kind of resistance to High temperature, high pressure resistant enhancing thermoplastic composite tube successively include inner tube, enhancement layer, outer tube from inside to outside;Said inner tube and enhancement layer Between be provided with internal insulation, outer heat insulation layer is provided between the enhancement layer and outer tube.CN201120466107 is a kind of continuous The multiple pipe of fiber prepreg tape winding enhancing
The patent includes tube wall outer layer and tube wall internal layer, and compound setting is by continuous glass between the tube wall internal layer and tube wall outer layer Glass fiber PE prepreg tape cross-helicity is wrapped in enhancement layer made of tube wall internal layer surface, and enhancement layer cross winding is in tube wall internal layer Outer surface, and be integrally formed with tube wall internal layer, the fusion of tube wall outer layer.The utility model obtains compound by using above-mentioned technology Pipe, novel in design, structurally reasonable, the shortcomings that overcoming both metal tube and steel-plastics composite pipe, using continuous glass-fiber PE prepreg tape The problem of cross winding is integrated as middle reinforcement layer, three layers of fusion, and production technology is controllable, and interfacial separation is not present, and it is resistance to Compressive Strength is high, cost is also greatly lowered, and has very high cost performance.CN201310705553 continuous fiber reinforcement polyolefin is multiple It closes pipe and its preparation process patent is related to a kind of continuous fiber reinforcement polyolefin multiple tube and its preparation process, including internal layer modeling Interior hot melt adhesive layer is arranged outside, continuous fiber impregnated tape is arranged outside interior hot melt adhesive layer for expects pipe, the inner layer plastic tube, and continuous fiber soaks External hot melting glue-line is set outside stain band, outer layer plastic tube is set outside external hot melting glue-line, which effectively increases the resistance to of composite pipe Compressive Strength, multiple tube crushed material can directly have longer glass with recycling and reusing, simple process and low cost, and in crushed material Fibre is used as reinforcing material, which can be used as high-intensitive enhancing modified materials and use.
It is enhancing that sum up all patents, which are all not involved with high pressure and large-diameter pipeline after being satisfied with circumferential pressure, Axial stress and the Strengthening Design made.
With the pipe-line system of pressure, the more big corresponding axial tension stress of its bigger basal area of caliber increases at geometry grade;Together Its basal area of the pipe-line system of caliber is identical, but increases exponentially as pressure increases exponentially its axial tension stress.
The continuous fiber reinforced plastic compound pipeline complex pipeline sold in the market is twined with circumferential unidirectional prepreg tape hot melt Requirement of 2.0MPaDN500mm or less the pipe-line system to axial tensile stress is satisfied with around pipeline sandwich layer.
Summary of the invention
