Abstract
The invention provides a glass fiber reinforced polyethylene composite material pipe and a manufacturing method thereof. The glass fiber reinforced polyethylene composite material pipe comprises a polyethylene pipe, wherein the polyethylene pipe comprises a polyethylene inner pipe and a polyethylene outer pipe, and a glass fiber reinforced layer is embedded between the polyethylene inner pipe and the polyethylene outer pipe. One-layer or more-layer glass fiber cloth or glass fiber wires or glass fiber tubular fabrics are wound in the middle of the high-density polyethylene pipe wall to enable the thickness of the pipe wall to be decreased from original two thirds to one half. In addition, main load is undertaken by a glass fiber material, stress born by the glass fiber material is decreased remarkably, and accordingly the creep deformation problem of an original modified polyethylene pipe is solved. The glass fiber reinforced polyethylene pipe can be used as a water supply and drainage pipe and can also used as a coal-mine gas discharge pipe and the like.
Description
Technical field
The invention belongs to field of compound material, relate to high density polyethylene (HDPE) (HDPE) composite material tube that a kind of glass fibre strengthens.
Background technique
Be accompanied by the step of civilization of human society, " pipe " converting new face always, from water supply and drainage pipe to gas drainage pipe, bearing new role.And the material of manufacturing pipe is also in continuous differentiation, from tile, cement pipe, steel pipe, until plastic tube composite material tube of today etc.Because steel pipe has a lot of defects, as large in weight, be difficult for installing; Poor corrosion resistance, needs frequent maintain and replace etc., so people attempt replacing steel pipe with glass fibre reinforced plastics, although solved, weight is large, the problem of poor corrosion resistance, has also brought new problem simultaneously: poor toughness, fragile, non-refractory etc.Last century, 80-90 age pvc pipe was come into the every aspect of people's lives, and meanwhile it is also as a kind of novel tube material.Pvc pipe really solved steel pipe weight greatly, the problem of not corrosion-resistant and Glass Steel Tube poor toughness, but its anti-static electricity property is poor, scale straight connector is too much, and hell to pay is installed, therefore mine this tubing seldom.The nineties middle and later periods in last century modified PE coal pipes for mining thering is good toughness, antistatic, high flame retardant, anticorrosive, shock resistance, the series of advantages such as wear-resistant is come out, yet polyethylene pipe exists, and tube wall is too thick, high cost, price fluctuate with oil price, when overpressure reach a certain height, easily there is the series of problems such as creep in tube wall.Glass fibre has high strength and high rigidity, if form composite material with polyethylene, the strength and stiffness that just can increase pipe solve creep problem, reduce wall thickness simultaneously.But because the difficulty of manufacture process, the polyvinyl piping materials that only has at present chopped strand to strengthen, but this is far from making full use of the material advantage of glass fibre.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency a kind of fiber-glass reinforced polyethylene composite material tube and preparation method thereof is provided, in the middle of high density polyethylene pipe wall, be wound around one or more layers glass fiber cloth or glass wire, make the wall thickness of pipe be reduced to original 2/3rds to half, because of Main Load, by fiber glass material, born simultaneously, the stress that polythene material bears significantly reduces, thereby has solved the creep problem of former modified poly ethylene pipe.The polyethylene pipe that this glass fibre strengthens can water supply drainage pipe, also can be for coal mine gas discharge pipe etc.
For achieving the above object, the present invention is by the following technical solutions:
A composite material tube, comprises polyethylene pipe, and polyethylene pipe comprises polyethylene inner tube and polyethylene outer tube, between polyethylene inner tube and polyethylene outer tube, is embedded with glass fiber reinforced layer.
Above-mentioned fiber-glass reinforced polyethylene composite material tube, described polyethylene outer tube is one deck.
Above-mentioned fiber-glass reinforced polyethylene composite material tube, described glass fiber reinforced layer is wound around and forms at an angle by glass wire and polyethylene inner tube axis.
Above-mentioned fiber-glass reinforced polyethylene composite material tube, described glass fiber reinforced layer is wound around and forms at an angle by glass fiber cloth and polyethylene inner tube axis.
Above-mentioned fiber-glass reinforced polyethylene composite material tube, described glass fiber cloth is unidirectional, two-way or multidirectional glass fiber cloth.
Above-mentioned fiber-glass reinforced polyethylene composite material tube, described glass fiber reinforced layer is glass fibre tubulose fabric.
Above-mentioned fiber-glass reinforced polyethylene composite material tube, described polyethylene outer tube is at least two-layer, is all embedded with glass fiber reinforced layer between adjacent two layers.
The preparation method of above-mentioned fiber-glass reinforced polyethylene composite material tube, comprise the following steps: a. first squeezes out polyethylene inner tube, b. then in polyethylene inner tube, be wound around glass fiber cloth or line, or sheathed glass fibre tubulose fabric, form glass fiber reinforced layer, c. is extruded polyethylene outer tube more finally.
The preparation method of above-mentioned fiber-glass reinforced polyethylene composite material tube, described glass wire and glass fiber cloth are to be wound around at an angle formation glass fiber reinforced layer with polyethylene inner tube axis.
The preparation method of above-mentioned fiber-glass reinforced polyethylene composite material tube, also comprises steps d. outside polyethylene, tube outside is wound around layer of glass enhancement layer again, and e. pushes layer of polyethylene outer tube again; Or steps d and e repetitive cycling are at least one times.
Adopt technique scheme, the present invention has following advantage: the present invention is wound around one or more layers glass fiber cloth or glass wire in the middle of high density polyethylene pipe wall, or glass fibre tubulose fabric, make the wall thickness of pipe be reduced to original 2/3rds to half, because of Main Load, by fiber glass material, born simultaneously, the stress that polythene material bears significantly reduces, thereby has solved the creep problem of former modified poly ethylene pipe.The polyethylene pipe that this glass fibre strengthens can water supply drainage pipe, also can be for coal mine gas discharge pipe etc.
