Abstract
The utility model relates to a polyethylene foamed plastic coated insulating copper pipe. The utility model is composed of a copper pipe, a polyethylene foamed body layer and a polyethylene protecting layer from the inside to the outside. The polyethylene foamed plastic coated insulating copper pipe of the utility model has the advantages of good thermal insulating effect, moisture prevention, fire prevention, stable product quality, long service life, etc. The utilization of the pipe has the advantages of engineering progress enhancement for the installation of an insulating copper pipeline and reduction of worker labor intensity.
Description
Technical field:
The utility model relates to the copper pipe heat-preserving composite pipeline, and particularly a kind of polyethylene foam is moulded and covered the insulation copper pipe.
Background technique:
The heat-insulation and heat-preservation of existing copper tube normally with thermal insulating material by manual wrapped or be set on the appearance of copper pipe; and then be wrapped on the thermal insulating material with boundary belt (cloth); need to consume great amount of manpower and material resources, not only labor intensity is big, and operator safety also has problems.Usually cause waste of material because of manual operations is improper, heat insulation effect is also bad, causes the energy and loss economically.Also usually because thermal insulating material is selected for use improper or the appearance protective layer does not have protective action and causes economic loss.
Also have a kind of copper tube to overlap the structure of plastic material sleeve pipe, the heat insulation effect of this structure is undesirable; The copper tube that manually wears foamed plastics is also arranged, and foaming body exposes outside it, insufficient strength, and easy damaged does not have the anti-aging protective layer, and heat insulation effect is bad.
The model utility content:
The technical problems to be solved in the utility model is exactly to cover the insulation copper pipe in order to overcome the defective of above-mentioned prior art, to provide a kind of polyethylene foam to mould, and creates conditions with the large-scale industrial production that realizes the copper pipe heat-insulation and heat-preservation.
The utility model polyethylene foam is moulded and is covered the insulation copper pipe; be characterized in circumferential and vertically even coating foam polyethylene layer on the edge, the outside of copper pipe; the external circumferential of foam polyethylene layer and the vertically even polyethylene protective layer that coats, said copper pipe, foam polyethylene layer and polyethylene protective layer hot melt adhesive are one.The thickness of foam polyethylene layer can be 1~20 times of copper pipe pipe thickness.
The technique effect that the utility model polyethylene foam is moulded the insulation copper pipe is: can improve effect of heat insulation and stable performance, simple in structurely be beneficial to a large amount of productions, and long service life, and have high economic benefit.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings:
Fig. 1 is the structural representation of the utility model Gereration of Foam Plastic Coated Thermal Insultation.
Among the figure: 1---copper pipe
2---the polyethylene blister layer
3---the polyethylene protective layer
Embodiment:
The structure of Gereration of Foam Plastic Coated Thermal Insultation of the present utility model as shown in Figure 1, internal layer is a copper pipe 1, the centre is a foam polyethylene layer 2, skin is a polyethylene protective layer 3.
The manufacturing process of the utility model Gereration of Foam Plastic Coated Thermal Insultation comprises the following steps:
Copper pipe surface is removed processing such as mud, dirt, greasy dirt and copper pipe preheating; The preparation of polyethylene foam raw material is mixed, heat fused; The preparation of polyethylene protective layer raw material is mixed, heat fused; Extruder is extruded the foam polyethylene of fusing and is compound with the surface extruding of copper pipe; Again with the fusing the protective layer polyethylene extrude, and with the coextru-lamination of foaming body layers of polyethylene; Cooling and shaping.
Show that with on probation performance and the advantage of the utility model polyethylene foamed plastic coated insulating copper tube are after tested:
(1), thermal conductivity factor is low, when 0 ℃ of mean temperature, pipeline thermal conductivity factor≤0.03 watt / rice. degree (w/m.k) only is 1/10th of traditional utilidor thermal conductivity factor; Identical Environmental condition under, the insulation material use amount that reaches identical heat insulation effect descends more than 50%.
(2), the closed pore heat-insulation layer, steam is difficult to be penetrated among the material, not only be incubated but also moistureproof, The wet resistance factor 〉=5000;
(3), owing to when making, in protective layer, also added fire retardant, anticorrisive agent etc., poly-Ethene protective layer fire-retardant fireproof, oxygen index (OI) is up to more than 28; Resistance to corrosion is strong, protective layer Hot strength 〉=10 MPas, the anti-damage intensity of resistance to compression height, service life 〉=30 year are fit to build Build the facility uses such as waterpipe.
(4), changed manual pipe insulation mode, use machinery equipment to produce the insulating copper tube road, Technological parameter and consistency of performance are good, and quality is secure. Therefore install simple and easyly, will greatly improve Project progress greatly reduces labour intensity.
Claims (2)
1, a kind of polyethylene foam is moulded and is covered the insulation copper pipe; it is characterized in that: circumferential and vertical evenly coating foam polyethylene layer (2) on the edge, the outside of copper pipe (1), at external circumferential and vertical even polyethylene protective layer (3) that coats of foam polyethylene layer (2).
2, polyethylene foam according to claim 1 is moulded and is covered the insulation copper pipe, and the thickness that it is characterized in that foam polyethylene layer (2) can be 1~20 times of copper pipe (1) pipe thickness.
