Description
Affiliated technical field
The invention belongs to the tubing class, is the improvement enhancing to polyvinyl piping materials, and its name is called four-layer composite metal enhancement polyethylene pipeline.
Background technique
Present domestic plastic tube mainly adopts overall plastic solid wall pipe material, because the rise of oil price and belong to non-renewable resource, so cause the rising of tubing cost also to be unfavorable for the saving of the energy; Because the restriction of material own causes the bearing capacity of overall plastic solid wall pipe material lower, generally is no more than 1.6MPa, application is narrow.
And domestic also have in plastic tube to increase twine wire and strengthen tubing intensity, disclose as CN2313137Y that a kind of usefulness is metal knitted to reticulate, be combined into composite pipe with interior pipe and outer tube; CN2202838Y discloses the composite pipe that interlayer between a kind of pipe material inner wall and the outer wall has the layer of metal mesh grid; CN2142168Y discloses the composite pipe that scribbles adhesive layer between a kind of winding steel wire layer of one deck at least and plastic core pipe and the plastic outer layer, above-mentioned tubing generally all adopts three-decker, the flexibility deficiency, cause the cost height of tubing, do not reach the purpose of saving, and pressure generally also can only reach 2.5MPa, can not satisfy the demand in market far away.Especially use in the polyvinyl piping materials in the colliery, the colliery requires antistatic, flame resistant with polyvinyl piping materials, and requirement reaches the pressure of 4-5MPa, the metal of overall plastic solid wall pipe material and three layers strengthened polyvinyl piping materials and can not meet the demands this moment, every layer raw material can only use raw material antistatic, flame resistant, cause tubing cost height, manufacturing efficiency is low, power consumption is big, wasted the national energy.
Summary of the invention
The purpose of this invention is to provide a kind of rational in infrastructure, bearing capacity is high, the pipe applications face is saved and can be expanded to raw material flexible configuration, materials novel polyethylene tubing.
The technical solution adopted for the present invention to solve the technical problems is: adopt four-layer composite metal enhancement polyethylene pipeline, its structure characteristic is that tubing is divided into four layers of composite structure and strengthens by metal, be divided into core inner tube layer, core outer tube layer, metal, coating modification layer, coat outer.Four layers of tubing can be adopted different raw material, be used for satisfying the requirement of difference in functionality, purposes.
The present invention solves its technical problem and can also adopt following technical measures further to realize.
Four-layer composite metal enhancement polyethylene pipeline of the present invention, wherein, the core pipe of tubing is the structure of core inner tube layer and the two-layer coextru-lamination of core outer tube layer.
Four-layer composite metal enhancement polyethylene pipeline of the present invention, wherein, the metal of tubing is arranged in outside, the coating modification layer of tubing core pipe.
Four-layer composite metal enhancement polyethylene pipeline of the present invention, wherein, the metal of tubing is steel wire, steel band or the steel wire stripe be made up of steel wire.
Four-layer composite metal enhancement polyethylene pipeline of the present invention, wherein, the metal enhanced form of tubing is the winding form.
Four-layer composite metal enhancement polyethylene pipeline of the present invention, wherein, the metal enhanced form of tubing is the establishment form.
The invention has the beneficial effects as follows when each layer selected different raw material for use and can produce different products, can satisfy different clients' demand; Metal in the tubing has improved the bearing capacity of tubing, has reduced raw-material consumption and tubing weight, has expanded the application of tubing, has reduced the cost of tubing, has reduced working strength of workers, has improved manufacturing efficiency.
This kind tubing has makes the characteristics simple, in light weight, that cost is low, has saved human and material resources greatly.For example: the present invention is applied in plumbing on the special industries such as colliery, air-supply, whitewashing and above the gas pumping tubing, human and material resources can have been saved greatly, and the tubing bearing capacity is strong, in light weight, easy to connect, interchangeability is good, can satisfy the requirement of all trades and professions.

Embodiment
Referring to shown in Figure 1, the core pipe 6 of four-layer composite metal enhancement polyethylene pipeline 7 proposed by the invention is formed by compound the extruding of coextru-lamination mould by core inner tube layer 1 and core outer tube layer 2, metal 5 is arranged in core pipe 6 outside coating modification layers 3, and outermost surface is to coat outer 4.
By coating modification layer 3 metal 5 and core pipe 6 and coating outer 4 are closely linked together.This coating modification layer 3 is a kind of high-performance adhesive materials, belongs to high density polyethylene (HDPE) remodeling material, with high density polyethylene (HDPE) under heating condition fully fusion be one, simultaneously, its polar bond and metal 5 have extremely strong adhesive property.Because the existence of coating modification layer 3 makes metal 5 and polyethylene have better composite effect.
In the application of colliery, the colliery requires the inside and outside antistatic surface of tubing with polyvinyl piping materials, and tubing itself can be fire-retardant, and requires to have certain bearing capacity and ring stiffness.The materials of coating of the tubing of four-layer structure at this moment outer 4 and core inner tube layer 1 adopt antistatic, fire-retardant raw material, and 3 on core outer tube layer 2 and coating modification layer need to adopt fire-retardant material to get final product, greatly reduce the loss of material property, and the existence of metal 5 has improved the bearing capacity and the ring stiffness of tubing, reduce the weight and the raw material materials amount of tubing, also reduced the cost of tubing.Adopt that the tubing 7 of this kind structure has higher performance, lower cost, materials, stronger impact property, better processability can satisfy different requirement of client more flexibly.
Referring to Fig. 2, Fig. 3, shown in Figure 4, the enhanced form of the steel wire 8 of four-layer composite metal enhancement polyethylene pipeline 7 proposed by the invention or steel band 9 or steel wire stripe 10 is the winding form, it is to be entwined by steel wire 8 or steel band 9 or steel wire stripe 10 to have high ring stiffness, tubing 7 proposed by the invention has thinner wall thickness than the tubing of other types under equal ring stiffness condition, lower cost, lighter weight especially is applied in above the heavy caliber pipe in the colliery.
Referring to shown in Figure 5, the enhanced form that four layers of composite steel wire proposed by the invention strengthen the steel wire 8 of polyvinyl piping materials 7 is a steel wire establishment form, because steel wire 8 is woven into reticular structure and forms an integral body, except having very high ring stiffness, also has very high bearing capacity, can proper functioning under 5MPa, and common tubing can only run on below the 2.5MPa, especially be applied to giving in the colliery, above the drainage pipe, have in light weight, characteristics such as impact resistance is strong, corrosion-resistant, non-scaling, bearing capacity is big, cost is low.
