Abstract
The utility model relates to a film coated thermal insulating casing pipe. A thermal insulating casing pipe is made of multilayer polyethylene materials in a high-temperature composite mode, and then, the outer layer of the thermal insulating casing pipe is coated with cellular protective film by a roller in a hot rolling mode. The utility model has the advantages of simple manufacturing technique, high tensile strength of the thermal insulating casing pipe, and high performance of temperature difference resistant of the thermal insulating casing pipe.
Description
The utility model relates to a kind of thermal insulation casing.
The casing pipe sleeve that the method that pipe insulation is at present adopted normally is bonded into opening with rock wool or glass wool carries out fastening on pipeline again; Or with raw materials such as polyamine fat with the foaming method to pipe insulation.The former shortcoming is that water proofing property and heat insulating ability are poor, and human body is had harm; The latter's shortcoming is that construction is complicated, causes human body to poison sometimes.Also occurred a kind of tubular type lagging of polyethylene board MULTILAYER COMPOSITE recently on the market, heat insulation effect improves greatly, but temperature resistance difference and tensile strength are desirable not enough.
The purpose of this utility model provides a kind of overlay film thermal insulation casing.
After the purpose of this utility model was achieved in that polyethylene thermal insulating material MULTILAYER COMPOSITE reaches desired thickness, the method for pressing with the roller hot-rolling was laminated with layer protecting film at the thermal insulating material skin, and its decorative pattern is a trellis.
The utility model improved the tensile strength of thermal insulation casing and the performance of opposing temperature variation greatly, and coating technique is simple, cost is low after being laminated with layer protecting film.
Describe structure of the present utility model and working condition in detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model protective film schematic representation.
The utility model is after the polyethylene thermal insulating material reaches desired thickness by the thermal source MULTILAYER COMPOSITE; the method that adopts the roller hot-rolling to press is laminated with layer protecting film at the skin of thermal insulating material; normally polyethylene film, BOPP film or aluminium film; the protective film decorative pattern is a form, is easy to be laminated with, technology is simple, cost is low.
