Description
Technical field
The utility model is related to a kind of plastic pipe with high-wear resistance, it is applicable but be not limited only to mine, change
The fields such as work convey the higher fluid of friction coefficient.
Background technology
The tradition plastic pipes such as including polyethylene material lead in the smaller fluid of the friction coefficient such as conveying water, natural gas
It is often adapted to and meets using needs and sufficiently long service life, but for defeated in the special industries such as such as mine, chemical industry
When sending the fluid containing more rugged solid-state particulate matter, since the friction coefficient of fluid is larger, it can significantly shorten these plastic tubes
The service life of material.For this purpose, traditional solution is typically to manufacture the pipe of tubing using such as modified poly ethylene modified material
Wall, to improve the wear-resisting property of tubing entirety, but this modifying plastics mode is to including the common used materials wear-resisting property such as polyethylene
Raising be limited, and cost performance is not high, it is difficult to meet actual operation requirements.In addition, although whole be adopted as elastic rubber
The tubing of body material can improve wear-resisting property and extend the service life, but its manufacturing cost and use cost is very high, causes to be difficult to promote general
And.
Utility model content
In consideration of it, the utility model provides a kind of improved wear resistant type plastic tubing, can not only significantly improve its
Wear-resisting property when trandfer fluid, and substantially reduce cost.
The wear resistant type plastic tubing of the utility model, basic structure be in the tubing with plastic outer wall layer tube wall,
It is provided with the inside pipe wall layer by rubber elastomer wear-resistant material.Wherein, the rubber elastomer for constituting pipe material inner wall layer is wear-resisting
Material, according to it is different using field/occasions at present can there are many selection, including natural rubber, butadiene-styrene rubber, butadiene rubber,
Fluorubber etc..For example, for chemical field, it is preferably selected while there can also be the rubber elastomer of specific Corrosion Protection wear-resisting
Material.For the thickness of the rubber elastomer wear-resistant material of the pipe material inner wall layer, field and field can also be used according to different
The actual needs of conjunction and determine.
On the basis of above-mentioned basic structure, to further increase the wear-resisting property of tubing, in the inside pipe wall layer
Rubber elastomer wear-resistant material can also be used and is wherein at least compounded with including wire, metal tape, glass fibre wear-resistant material
One of kind Compound rubber elastomer wearable material, be conducive to further increase performance and reduce cost.
To enable the rubber elastomer wear-resistant material layer and plastic outer wall layer to be preferably interconnected, may be used not
The inside pipe wall layer of the rubber elastomer wear-resistant material is set mutually securely to be engaged with plastic outer wall layer with mode.For example, can be with
Hot melt adhesive layer of the two through having many reports and/or the appropriate form used at present is set to be interconnected；Can also use makes
The inside pipe wall layer of the rubber elastomer wear-resistant material is to form whole shape through mold coextrusion mold mode with plastic outer wall layer
The structure of formula.
On the basis of above structure, the plastic outer wall layer described in structural pipe wall and rubber elastomer wear-resistant material
Between inside pipe wall layer, can also further it be bonded to including spiral winding metal reinforcg structure layer and/or plastics enhancing structure layer
Structure, to formed with multiple material MULTILAYER COMPOSITE tube wall tubing.Particularly preferred mode is, in structural pipe wall
Between the inside pipe wall layer of the plastic outer wall layer and rubber elastomer wear-resistant material, ecto-entad has simultaneously engaged with spiral successively
Metal reinforcg structure layer and plastics enhancing structure layer are wound, for improving the tubing overall performance including wear-resisting property, more
It is advantageous.
By largely developing and testing, in the internal face for including the plastic pipes such as common polyethylene, in the form of coating
After inside pipe wall layer provided with rubber elastomer wear-resistant material, to substances such as solid granulates in fluid to tube wall impact force
Elastic buffer acts on, and is remarkably improved the wear-resisting performance of plastic pipe.This structure type of the utility model, combines poly- second
The cost of alkene tubing is low, long lifespan and the advantages of convenient for construction, while the wear-resisting feature by having rubber elastomer wear-resistant material,
Thus there is very high cost performance for the conveying wear-resisting property for improving tubing.Manufacture to such tubing, and using existing
Traditional handicraft can facilitate realization.For example, can be added between rubber elastomer wear-resistant material and vinyon appropriate
After compatilizer, extrusion molding forming is controlled using multi layer extrusion mold coextrusion mold, and by the speed of extrusion die and extruder
Then the thickness of polyethylene layer and rubber elastomer wear-resistant material layer in the process is shaped using vacuum cooled shaping equipment, and
Form that internal layer is the inside pipe wall of rubber elastomer wear-resistant material, outer wall is the compound of polythene material through the processes such as drawing, cutting
Tubing.It wherein, can also be in metal materials conducts such as the outer surfaces, then composite steel wire, steel band of this tubing obtained by co-extrusion
After middle layer, then polyethylene extrusion plastics form the outer wall layer of tubing, to form the MULTILAYER COMPOSITE tubing of multiple material.This
Outside, corresponding dedicated adhesive or hot melt adhesive can also be used, forms the tubing inner and outer pipe parietal layer structure with bonding way.
For example, can leading extruded rubber elastomer wearable material pipe as internal layer, then in outer surface recombination polyethylene or steel
The other materials such as silk steel band, rubber elastomer wear-resistant material layer are mutually viscous using corresponding hot melt adhesive with the composite material of outside
Connect, obtained pipeline both can be used directly, can also further compound other materials and be formed as the more of multiple material
Layer composite pipe.
It can be seen that the tubing of structure type described in the utility model, in trandfer fluid, especially conveying is containing coarse
When the higher fluid of the friction coefficient such as particulate matter, the rubber elastomer wear-resistant material layer in pipe material inner wall face can increase substantially wear-resisting
Property, and can be widely used for including the plastic materials such as polyethylene or tube wall be externally provided with the enhancing structures such as metal plastic pipe life
Production, and can be main but be not limited only to be used in the fields more demanding to tubing wearability such as mine, chemical industry, pipeline can be extended
Service life and increase economic efficiency, have good technical feasibility and market prospects.
