Abstract
The utility model discloses a heat-insulation pipe sleeve. The heat-insulation pipe sleeve is composed of a polyethylene film on a surface layer, a crosslinked polyethylene closed hole foamed plate material on a middle layer, and crosslinked or non-crosslinked closed hole foamed pipe material on an inner layer. The polyethylene film on the surface layer is tightly clung on the crosslinked polyethylene closed hole foamed plate material on the middle layer, and is made into a composite embossing shape. The heat-insulation pipe sleeve has the advantages that the heat-insulation pipe sleeve has convenient installation, beautiful appearance, good heat insulation effect, good anti-frost performance, and easy volume production, when the heat-insulation pipe sleeve is bent, the heat-insulation pipe sleeve is not cockled, production equipment has less investment.
Description
The utility model relates to a kind of heat-insulating cover that is applicable to the conveyance conduit insulation of refrigeration (heat) equipment.
Present heat-insulating cover, a kind of is foam rubber and plastic heat-insulation and heat-preservation pipe, and this material is that matter is soft, and the pipeline friction is big, and the installation (interting) that is used for middle-size and small-size pipeline is difficult.Investment of production equipment is bigger, and the prices of raw and semifnished materials are higher.Another kind gathers second weighing apparatus foam insulated pipes, matter is soft; the installation of middle-size and small-size pipeline (interting) is easier to; equipment investment is little; the prices of raw and semifnished materials are cheaper; what mainly contain that the seamless foaming pipe of one step forming foaming and two steps are shaped (making tubing by sheet material) has a seam thermal insulation pipe; main deficiency is: do not have protective layer; to wrap up protective layer during construction; foaming material cracky; seam crossing is easy to crack, and tightness is relatively poor, and the dewfall phenomenon easily takes place; also have the harder of other, inconvenient middle-size and small-size pipeline construction as foaming material shells such as polystyrene, polyurethane.More than these all are the individual layer foaming products, easily wrinkle when surface finish slide plate, bending.
The purpose of this utility model is to provide a kind of good heat-insulation effect, the antisweat performance is good, attractive in appearance and do not wrinkle during bending, heat-insulating cover easy for installation.
For achieving the above object, heat-insulating cover of the present utility model is made up of the polyethylene film on top layer, the crosslinked polyethylene closed pore foaming plate in middle level, the crosslinked or invalid closed pore foam pipe of internal layer, the polyethylene film on top layer is close on the crosslinked polyethylene closed pore foaming plate in middle level, and makes the composite embossed shape.
After adopting such structure, the utlity model has following advantage:
1, structure is three laminates, can arrange in pairs or groups flexibly and make the goods of different usage requirements.
2, the top layer is the embossing moulding, and is wrinkle resistant during attractive in appearance and bending.
3, seal mutually between layer and the layer, effect of heat insulation excellence, antisweat performance are good.
4, itself have embossing attractive in appearance and protective layer, do not need to wrap up other protective film in use.
5, it is convenient and easy that the centering small pipeline is installed (interting).
6, less being easy to of equipment investment produced in enormous quantities.
Fig. 1 is the structural representation of the concrete a kind of embodiment of the utility model.
Heat-insulating cover of the present utility model as shown in Figure 1 is by the crosslinked of the crosslinked polyethylene closed pore foaming plate 2 in the polyethylene film 1 on top layer, middle level, internal layer or do not have crosslinked closed pore foam pipe 3 and form, the polyethylene film 1 on top layer is close on the crosslinked polyethylene closed pore foaming plate 2 in middle level, and makes the composite embossed shape.The thermal insulating material of heat-insulating cover of the present utility model, internal layer adopt butagas physics extrusion foaming technology one step forming.Middle level thermal insulating material and outer protective layer adopt mold pressing chemical blowing sheet material and polyethylene film hot melt embossing moulding.Last internal layer foaming pipe and preformed foam sheet adopt the heat fusion mode to make tubulose.
Claims (1)
1, a kind of heat-insulating cover, it is characterized in that: this heat-insulating cover is by the crosslinked of the crosslinked polyethylene closed pore foaming plate (2) in the polyethylene film (1) on top layer, middle level, internal layer or do not have crosslinked closed pore foam pipe (3) and form, the polyethylene film on top layer (1) is close on the crosslinked polyethylene closed pore foaming plate (2) in middle level, and makes the composite embossed shape.
