Abstract
The utility model discloses a double-layer co-extruded polyolefin composite pipeline which is characterized by comprising a dark inner pipe made of a polyolefin material and a bright-color outer pipe made of the polyolefin material. The inner pipe and the outer pipe are subjected to co-extrusion composite molding. The pipeline is made into an inner layer and an outer layer; the inner layer is the dark inner pipe made of the polyolefin material, and the outer pipe is the bright-color outer pipe made of the polyolefin material; the inner pipe and the outer pipe are subjected to the co-extrusion composite molding; the bright-color outer pipe is nice in appearance and bright in color as the bright-color outer pipe can be in green, blue, red and the like; the dark inner pipe is anti-UV, good in light shielding performance and not easy to propagate bacteria; the double-layer structure is good in intensity and long in service life.
Description
Technical field
The utility model relates to double-layer coextrusion polyolefin multiple tube.
Background technique
Existing polyolefin pipe mostly is individual layer pipeline, and individual layer pipeline is simple in structure, easily manufactured, but function is few, if make the individual layer pipeline of light tone, and beautiful shape, but antiultraviolet, shading poor performance, if make dark individual layer pipeline, profile is plain.
Summary of the invention
The purpose of this utility model is the shortcoming existing in order to overcome prior art, and a kind of beautiful shape is provided, and antiultraviolet, shading performance are good, are not easy breed bacteria, the double-layer coextrusion polyolefin multiple tube that structural strength is good.
The technological scheme of the utility model double-layer coextrusion polyolefin multiple tube is: it is characterized in that comprising that polyolefine material makes outer tube, inner tube and outer tube coextru-lamination moulding that dark inner tube and polyolefine material are made light tone.
The utility model discloses a kind of double-layer coextrusion polyolefin multiple tube, pipeline is made inside and outside two-layer, wherein internal layer is that polyolefine material is made dark inner tube, outer make the outer tube of light tone for polyolefine material, inner tube and outer tube are by coextru-lamination moulding, its color of the outer tube of light tone can be the color such as green, blue, red, beautiful shape, bright in luster beautiful, and dark inner tube antiultraviolet, shading performance are good, be not easy breed bacteria, and double layer construction intensity is good, long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model double-layer coextrusion polyolefin multiple tube.
Embodiment
