Abstract

The utility model discloses a multilayer coextrusion composite pipe, which comprises a surface layer (1), a foaming layer (2) and a separating layer (3). The foaming layer (2) wraps the outside of the separating layer (3), the surface layer (1) wraps the outside of the foaming layer (2), and the surface layer (1), the foaming layer (2) and the separating layer (3) are integrated by means of extrusion. The multilayer coextrusion composite pipe adopts the structure that the surface layer, the foaming layer and the separating layer are compound by the extrusion, has excellent separation, heat-insulation and sound isolation performances and fine use strength, is suitable for being used as a water pipe and an electric cable wrapping pipe, can be rich in attractiveness on the appearance of a pipe body by distributing metal powder in the surface layer, has the function of electrostatic resistance, is extremely suitable for being used as an outdoor water pipe, is low in production cost, can be widely applied, and has the advantages of simple structure, easy manufacturing and fine use effect.

Description

Multi-layer co-extruded composite pipe

Technical field

The utility model relates to a kind of plastic pipe, especially a kind of multiduty multi-layer co-extruded composite pipe.

Background technique

At present, the plastic pipe with FLUID TRANSPORTATION function is used widely in different field usually as resident's water pipe, mine water pipe, slot sleeve etc.Modal plastic pipe is the individual layer extruding pipe, and this pipeline is widely used owing to low cost.But, therefore be subjected to a lot of restrictions in the use because its function ratio is more single.Along with the development of technology, during the composite pipe that multilayer is extruded has been put into production more and more and used, but the multilayer extruding pipe is along with the appending of its function, and its cost of production is also improved accordingly.

Summary of the invention

The purpose of this utility model is: a kind of multi-layer co-extruded composite pipe is provided, and it has more practicability and higher function, and low production cost, to overcome the deficiencies in the prior art.

The utility model is achieved in that multi-layer co-extruded composite pipe, and it is made up of top layer, foaming layer and barrier layer, and foaming layer wraps in outside the barrier layer, and the top layer wraps in outside the foaming layer, and top layer, foaming layer and barrier layer become one by co-extrusion.

In the top layer, be uniformly distributed with metal powder.

Metal powder is aluminium powder or copper powder.

Owing to adopted technique scheme, compared with prior art, the utility model adopts top layer, foaming layer and the compound structure of extruding of barrier layer, should have good barrier performance, thermal insulation property and sound insulation value by multiple layer extruding pipe, and have good working strength, and be suitable as water pipe and slot sleeve and use, but also the metallic dust that can in the top layer, distribute, it is attractive in appearance that the outward appearance of pipe shaft is rich in, and have anlistatig effect, is suitable as very much outdoor water pipe and uses; And this composite pipe low production cost, can be employed widely.The utility model is simple in structure, makes easily, and using effect is good.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model.

Embodiment

Embodiment of the present utility model: the structure of multi-layer co-extruded composite pipe as shown in Figure 1, adopt the compound explained hereafter of extruding to obtain the pipeline of three-decker, wherein innermost layer is for being added with the barrier layer 3 of organo montmorillonite (perhaps polyvinyl alcohol etc. has the material of barriering effect), the mesosphere is the foaming layer 2 of having added stabilizer, and outermost surface is that aluminium powder 4(also can adopt copper powder or other cheap metallic dusts that generally has better dispersion effect in polymer) (plastic resin can adopt ageing resistance strong with plastic resin, acrylic resin that can multi-layer co-extruded production, polyethylene resin or Corvic) blend is the top layer 1 of material.

Because this composite pipe is divided into three-decker, it has multiple function of use: barrier layer 3 pairs of water, gas have excellent barrier property; Foaming layer 2 can be played the effect of insulation, sound insulation, and is of many uses; Top layer 1 has also added metallic dust 4 satisfying under the prerequisite of working strength, can play anlistatig effect, has effect attractive in appearance again, makes pipe shaft have metallic travel, and outward appearance looks like metal tube.And the material source of this multilayer structure is extensive, low production cost, and fabrication and processing is convenient, can be widely used.

Claims

1. multi-layer co-extruded composite pipe, it is characterized in that: it is made up of top layer (1), foaming layer (2) and barrier layer (3), and foaming layer (2) wraps in outside the barrier layer (3), and top layer (1) wraps in outside the foaming layer (2); Top layer (1), foaming layer (2) and barrier layer (3) become one by co-extrusion.
