Description
Technical field
The present invention relates to a kind of satisfied different purposes, multi-component and multi-layer co-extruded modified high-modulus plastic composite tube.
Background technology
At present, down with feedwater, drainpipe, gas drainage under suction pipe major part still adopts steel pipe to the mine of China, owing to the steel pipe corrosion resistance, wear no resistance, annual its effective thickness constantly reduces, and causes its service life short, and security reduces; Though adopted a lot of technology,, coating zinc-plated to handle and the plastic-blasting processing used in recent years etc., improved the decay resistance of steel pipe as steel tube surface.But because technical restriction, barrier propterty is also unsatisfactory.Therefore novel mine is down with feedwater, drainpipe, the drawing-off gas pipe continues to bring out, the polyethylene pipe, polyvinyl chloride pipe, the glass reinforced plastic pipe that add the flame-retardant and anti-static agent are arranged, these pipe performances improve constantly, cost constantly reduces, but still can not satisfy the high standard requirement of using feedwater, draining and drawing-off gas under the mine.Mainly show following some: 1, the composition more complicated of methane gas under the mine, macro-corrosion gas and steam are arranged, the rigidity of steel pipe is very good, but perishable, used process for treating surface can not well solve the binding ability between steel and the protective layer; 2, polyethylene, the polyvinyl chloride solid wall pipe of the agent of interpolation flame-retardant and anti-static have decay resistance preferably, but owing to contain harder sandstone composition in the water under the mine, the mar proof of tubing is poor, and long-term serviceability reduces; 3, glass reinforced plastic pipe is owing to be subjected to the methane gas effect easily to cause " weathering " to influence service life.The mine is like this with tubing, other field also in various degree have a similar problem.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the problem that prior art exists, design a kind of requirement of using operating mode according to engineering, the composite plastic tubing that can " assemble ".Its good integrity, intensity height, ageing-resistant, corrosion-resistant, wear-resistant, shock resistance, fire-retardant, antistatic, cost is low etc., these characteristics can embody a concentrated reflection of on a certain tubing simultaneously, also can show respectively on the tubing of different purposes.
The present invention will solve the technical scheme that its technical problem adopts: adopt multi-component and multi-layer co-extruded technology, make each layer all have difference in functionality, satisfy the different performance requirement; Associativity will be got well between layer and interlayer, the component, guarantees that the globality of tubing will be got well; As the compound mine of the three-layer co-extruded modified high-modulus plastic of three components pump drainage water pipe, it is outer to be shock resistance, corrosion-resistant, ageing-resistant, fire-retardant, anti-static polyethylene layer (1), the intermediate layer is high strength (or low-cost), shock resistance, corrosion-resistant, flame retardant plastics layer (2), internal layer is a high abrasion, shock resistance, corrosion-resistant, fire-retardant, anti-static plastic layer (3), it is characterized in that: middle modified high-modulus plastic layer (2) is for being continuous phase with the polyethylene, with PETG, polybutylene terephthalate (PBT), Merlon, polyformaldehyde etc. are decentralized photo, formed blend or their alloy or their enhancing modified product etc., but be not limited to these materials; Wherein inorganic enhancing filler is that high-molecular organic material blend, alloy etc. have added necessary bulking agent through surface activation process.Internal layer high-wear-resistance and flame-retardant antistatic layer (3) is a modification high-wear-resistance and flame-retardant anti-static polyethylene layer, by polyethylene and crosslinked polyethylene or ultra-high molecular weight polyethylene or polytetrafluoroethylene (PTFE) or polyformaldehyde, and necessary compositions such as auxiliary agent, but be not limited to these materials.
This tubing outermost layer and innermost layer adopt the flame-retardant and anti-static material, make tubing have the excellent security energy; Internal layer adopts high abrasion resisting material as modifications such as crosslinked polyethylene, ultra-high molecular weight polyethylene, polytetrafluoroethylene (PTFE), polyformaldehyde, reduces that under the mine sandstone improves the life-span of tubing to the abrasive action of tubing; Middle modified high-modulus plastic layer is given good voltage endurance capability of tubing and the ability that is subjected to outside destroy; The inorganic filler modification, as: alkali-free glass fibre, high-modulus calcium carbonate, high-modulus talcum powder, wollastonite, potter's clay etc. and high-molecular organic material: PETG, polybutylene terephthalate (PBT), Merlon, polyformaldehyde etc., increase the elastic modelling quantity of polythene material, improved the creep resistance of material; Surfactants such as silane coupler, titanate coupling agent, aluminate coupling agent increase the adhesion between inorganic filler and the polyethylene, guarantee the stable homogeneous of material property; The high-molecular organic material bulking agent improves the intensity of tubing as the adhesion of the storeroom that increases such as maleic anhydride grafted polyethylene, acrylic ester grafted polyethylene are not allowed mutually.
Compared with prior art, the beneficial effect that had of the three-layer co-extruded modified high-modulus plastic multiple tube of the present invention's three components is: 1, with the steel pipe ratio, corrosion resistance, wearability are improved, the tubing long service life.2, the modified high-modulus plastic layer is adopted in the intermediate layer, the plastics solid wall pipe ratio outstanding with corrosion resistance, and the intensity and the voltage endurance capability of tubing are improved; 3,, internal layer adopts the high abrasion resisting material modification, improved that sandstone improves the tubing life-span to the wearing and tearing of tubing in the mine water of ore deposit, this is that steel pipe and plastics solid wall pipe are incomparable; 4, compare with the plastics solid wall pipe material of same size same material, cost reduces more than 10%.
Description of drawings
Accompanying drawing is the compound mine of the three-layer co-extruded modified high-modulus plastic of three a components pump drainage water pipe lateral cross section structural representation;
1. the ageing-resistant plastic layer 2. intermediate layer modified high-modulus plastic layers of outer flame-retardant and anti-static 3. internal layer high-wear-resistance and flame-retardant anti-static plastic layer.
The specific embodiment
With reference to accompanying drawing.
The raw material of this compound mine of three-layer co-extruded modified high-modulus plastic of three components pump drainage water pipe, comprise outer fire retardant antistatic plastic layer 1, intermediate layer modified high-modulus plastic layer 2, internal layer high-wear-resistance and flame-retardant anti-static plastic layer 3, all be what to have prepared in advance, use three extruders more respectively, make trilaminate material extrusion molding simultaneously by three-layer co-extruded mould through fusion plastification, and evenly be combined into the pipe that Mechanical Method can't be separated, make tubing through cooling and shaping.Three layers thickness can be controlled by the extrusion capacity of regulating extruder.
