Description
Technical field
The utility model belongs to hydrophily air-conditioning duct pipe technology field, and being specifically related to a kind of is high strength, low-expansion central air-conditioner prefabricated thermal insulation plastic composite pipe.
Background technique
Air-conditioning needs to adopt Cemented filling liquid in refrigeration and heating operations, must take isothermal holding.Traditional hydrophily air-conditioning duct uses Coating Steel Pipe or copper pipe, and isothermal holding is carried out again in job site.In using, Coating Steel Pipe causes " run, drip, leak ", simultaneously corrosion and scaling easily to cause a blockage because of corrosion, and the efficiency of operation of air conditioner is reduced greatly.A lot of air-conditioning company has now started to adopt novel plastic pipeline, as PPR pipe, solve the problem of corrosive pipeline preferably, and thermal conductivity is low, more energy-conservation.But because plastic pipe expansion coefficient is comparatively large, during Pipe installing, need slabbing be set, constructs comparatively loaded down with trivial details.On the other hand, conventional pipelines and pipe insulation are separately purchased, owing to being limited to people's why reason such as field condition, easily there is the problems such as thermal insulation layer loosens, insulation layer thickness is inadequate, cause heat insulation effect undesirable, produce condensed water, usual whole pipe network 2-3 just needs to be serviced.Market active demand exploitation a kind of high rigidity, low bulk, the duct products of high insulating effect upgrades to existing pipe network.
Model utility content
For the above-mentioned problems in the prior art, the purpose of this utility model is to provide a kind of central air-conditioner prefabricated thermal insulation plastic composite pipe, pays no attention to think of install the technical problems such as inconvenient with the burn into heat insulation effect solving existing air-conditioning duct.
Described a kind of central air-conditioner prefabricated thermal insulation plastic composite pipe, comprise composite pipe body, polyurethane foamed thermal-insulating layer and PE external sheath layer, it is characterized in that described polyurethane foamed thermal-insulating layer perfusion is arranged on composite pipe body outer surface, PE external sheath layer is coated is arranged on polyurethane foamed thermal-insulating layer outer surface.
Described a kind of central air-conditioner prefabricated thermal insulation plastic composite pipe, is characterized in that described composite pipe body is three-layer composite structure, is made up of in a molten state extruding and moulding PP-R skin, fibre modification polypropylene layer and PP-R internal layer.
Described a kind of central air-conditioner prefabricated thermal insulation plastic composite pipe, is characterized in that described PP-R skin, fibre modification polypropylene layer and PP-R internal layer three layers of wall ratio are 2:5:3.
Above-mentioned a kind of central air-conditioner prefabricated thermal insulation plastic composite pipe, comprise composite pipe body, polyurethane foamed thermal-insulating layer and PE external sheath layer, the perfusion of polyurethane foamed thermal-insulating layer is arranged on composite pipe body outer surface, PE external sheath layer is coated is arranged on polyurethane foamed thermal-insulating layer outer surface, and composite pipe body is made up of in a molten state extruding and moulding PP-R skin, fibre modification polypropylene layer and PP-R internal layer.The utility model, by adopting above-mentioned technology, has following beneficial effect:
1) the utility model is by arranging polyurethane foamed thermal-insulating layer in mesosphere, solve the impact of the personal factor that on-the-spot insulation occurs, in-site installation is more convenient, shortens the duration, insulation layer thickness, in strict accordance with the requirement of air conditioner water antisweat, has stopped condensation from design source.
2) the utility model is by arranging PE external sheath layer, has certain protective action, have the features such as weather-proof, anti-aging to polyurethane foamed thermal-insulating layer, substantially prolongs the working life of whole pipe-line system;
3) interior working pipe composite pipe body of the present utility model is three-layer composite structure, fibre modification polypropylene layer is set between PP-R internal layer and PP-R skin, reduce the coefficient of linear expansion of pipeline, improve the rigidity of pipeline simultaneously, thoroughly solve the etching problem of conventional steel, guarantee that inner-walls of duct is smooth, less scaling, make carry system water quality be improved significantly, system cloud gray model maintenance workload, expense reduce greatly, pipeline and pipeline equipment run more stable, straight attractive in appearance during installation.
Accompanying drawing explanation
Fig. 1 is the utility model horizontal section structural representation.
In figure: 1-PE external sheath layer, 2-polyurethane foamed thermal-insulating layer, 3-composite pipe body, 301-PP-R is outer, 302-fibre modification polypropylene layer, 303-PP-R internal layer.
Embodiment
Below in conjunction with Figure of description, the utility model will be further described, but protection domain of the present utility model is not limited in this:
As shown in Figure 1, central air-conditioner prefabricated thermal insulation plastic composite pipe of the present utility model, comprise composite pipe body 3, polyurethane foamed thermal-insulating layer 2 and PE external sheath layer 1, described polyurethane foamed thermal-insulating layer 2 perfusion is arranged on composite pipe body 3 outer surface, and PE external sheath layer 1 is coated is arranged on polyurethane foamed thermal-insulating layer 2 outer surface; Described composite pipe body 3 is three-layer composite structure, be made up of in a molten state extruding and moulding PP-R skin 301, fibre modification polypropylene layer 302 and PP-R internal layer 303, PP-R skin 301, fibre modification polypropylene layer 302 and PP-R internal layer 303 3 layers of wall ratio are 2:5:3.
As shown in the figure, described composite pipe body 3 and polyurethane foamed thermal-insulating layer 2 and PE external sheath layer 1 bonding mutually, described PE external sheath layer 1 is high density polyethylene (HDPE) outer protective layer, material is black PE100 pipeline material, described composite pipe body 3 is interior working pipe, it is by PP-R skin 301, fibre modification polypropylene layer 302 and PP-R internal layer 303 are formed in a molten state extruding and moulding, fibre modification polypropylene layer 302 material is glass fiber reinforcement random polypropylene layer, the material of described polyurethane foamed thermal-insulating layer 2 is hard polyurethane foam material, this foam material is a kind of collection waterproof, insulation, heat insulation in the new material of one.
