Background technique;
Patent 201020173314.9 " multi-layer co-extruded composite pipe " 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) are by being extruded as one.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 has a good working strength, being suitable as water pipe and slot sleeve uses, 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.
The problem that above-mentioned patent exists, because the material of top layer (1), foaming layer (2) and barrier layer (3) is different with density, when surface layer temperature and foaming layer and barrier layer temperature not simultaneously, the top layer easily produces transverse shrinkage with foaming layer and barrier layer separates and not isometric vertical contraction, reduces the working life of composite pipe.
Summary of the invention:
The purpose of this utility model is: 1, the outer thermal insulation pipe of the outer co-extrusion of internal layer indusion tube, thermal insulation property and the shock resistance and the sound insulation property of raising internal layer indusion tube.2, establish dovetail groove or convex tendon on the internal layer indusion tube outer wall, outer thermal insulation pipe is inlayed in the internal layer indusion tube outer wall dovetail groove or in the convex tendon groove, is prevented the outer thermal insulation pipe disengaging of internal layer indusion tube and outside co-extrusion.3, internal layer indusion tube outer wall dovetail groove edge or convex tendon process vertical gap, outer thermal insulation pipe is inlayed on the internal layer indusion tube excircle in the dovetail groove or in the convex tendon groove and vertically in the gap, is solved internal layer indusion tube and the vertical synchronous problem of outside co-extrusion skin thermal insulation pipe.4, gluing between internal layer indusion tube and outer thermal insulation pipe improves join strength between internal layer indusion tube and outer thermal insulation pipe, reduces radial contraction.
The dovetail that the utility model proposes connects the co-extrusion heat preserving perfusion tube, comprising: the internal layer indusion tube, and outer thermal insulation pipe, internal layer indusion tube outer wall is established dovetail groove or convex tendon, and outer thermal insulation pipe is inlayed in the internal layer indusion tube outer wall dovetail groove or in the convex tendon groove.
For solving the vertical asynchronous contraction problem of the temperature difference that internal layer indusion tube and outside co-extrusion skin thermal insulation pipe produce because of material is different with density, prefabricated internal layer indusion tube outer wall dovetail groove edge or convex tendon process vertical gap with gulleting machine, during co-extrusion, outer thermal insulation pipe is inlayed in internal layer indusion tube outer wall dovetail groove or the convex tendon groove and vertically in the gap.
For solving the vertical asynchronous contraction problem of the temperature difference that internal layer indusion tube and outside co-extrusion skin thermal insulation pipe produce because of material is different with density, prefabricated internal layer indusion tube outer wall dovetail groove or convex tendon process transverse groove, and outer thermal insulation pipe is inlayed in internal layer indusion tube outer wall dovetail groove or the convex tendon groove and in the transverse groove.
Internal layer indusion tube outer surface gluing, during co-extrusion, glue bonds together internal layer indusion tube and outer thermal insulation pipe, improves join strength between internal layer indusion tube and outer thermal insulation pipe, reduces radial contraction.
For improving corrosion resistance and the shock resistance that dovetail connects the co-extrusion heat preserving perfusion tube, outer thermal insulation pipe outer surface co-extrusion protective coating, the co-extrusion protective coating comprises: PVC, PE, PP, PPR, ASA, PMMA, PVDF, the co-extrusion protective coating manufactures color tube or manufactures transparent tube with base-material by adding colorant.
