Abstract

The utility model relates to a double-color three-layer co-extrusion polyethylene (PE) pipe. The double-color three-layer co-extrusion PE pipe is characterized by comprising an inner layer pipe (1), a middle layer pipe (2) and an outer layer pipe (3) sequentially from inside to outside, wherein the inner layer pipe (1), the middle layer pipe (2) and the outer layer pipe (3) are made of a common PE material, an enhanced PE material and a common PE material respectively and are co-extruded to form a whole body; and color masterbatches are added into the materials of the inner layer pipe (1) and the outer layer pipe (3) and are not added into the material of the middle layer pipe (2), so that the double-color three-layer co-extrusion PE pipe has the advantages of being provided with pipelines capable of distinguishing different mediums, improving ultraviolet resistance and not greatly increasing the cost.

Description

Double-colored three-layer co-extruded PE pipe

Technical field

The utility model relates to a kind of tubing, relates in particular to a kind of double-colored three-layer co-extruded PE pipe, belongs to the tubing technical field.

Background technology

The PE pipe is widely used in the non-pressure pipeline, as fields such as water supply, combustion gas, blowdown and communication cables.At present, PE entity tubing is single layer structure.The excellent performance of PE pipe, nontoxic, but its tube wall is thicker, it is general that tube wall is 130% of a pvc pipe under same operating pressure situation, price is generally than managing expensive 30% with the footpath with pressure P VC.Therefore price factor has influenced a large amount of uses of PE pipe.Pipeline and raising anti-uv-ray in order to distinguish different medium add color masterbatch in process of production, but the price of color masterbatch are comparatively expensive, cause PE pipe cost to roll up.Therefore seek a kind of pipeline and the raising anti-uv-ray that can distinguish different medium, and the PE pipe that cost can not roll up is particularly important.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of and can distinguish the pipeline of different medium and improve anti-uv-ray, and the double-colored three-layer co-extruded PE that cost can not roll up manages.

The purpose of this utility model is achieved in that

A kind of double-colored three-layer co-extruded PE pipe, it is characterized in that it comprises inner tube from inside to outside successively, middle tube and outer tube, described inner tube, the material of middle tube and outer tube is respectively the common polythene material, strengthen polythene material and common polythene material, the external diameter of this PE pipe is 80 ~ 105cm, the internal diameter of this PE pipe is 90 ~ 95cm, the thickness of described middle tube is 70 ~ 80cm, described inner tube, the three-layer co-extruded formation one of middle tube and outer tube, add color masterbatch in the material of described inner tube and outer tube, do not add color masterbatch in the material of described middle tube.

Compared with prior art, the beneficial effects of the utility model are:

The utility model is owing to add color masterbatch in the material of inner tube and outer tube, do not add color masterbatch in the material of middle tube, the pipeline that makes this double-colored three-layer co-extruded PE pipe have to distinguish different medium and improve anti-uv-ray, and the cost advantage that can not roll up.
