Abstract
The present invention provides a kind of aluminium-plastic pipe, and it includes inner tube and polyethylene foam layer successively from inside to outside, and inner tube has three layers, internal layer and outer layer are all pvc pipes, intermediate layer is aluminum pipe, and EVA film is stained between polyethylene foam layer and inner tube, and polyethylene foam layer outer surface is stained with EVA film.The aluminium-plastic pipe has function of heat insulation, and with corrosion resistant function, can be used for a long time.
Description
Technical field
The invention belongs to tubing technical field, it is related to a kind of aluminium-plastic pipe.
Background technology
Metallic conduit all opposed plastic materials in terms of anti-corrosive properties, install convenient are poor, and the world is advocating energy-conservation in addition
Consumption reduction, therefore people are gradually on sight input plastic tube.
The invention announced such as Chinese patent【The patent No. 201310569477.7】, a kind of antimicrobial form plastic-aluminum of the disclosure of the invention
Pipe, including the vertical weldering aluminum pipe by intermediate layer, vinyon internal layer, vinyon outer layer, and hot melt between layers
Glue glued adhesion layer coextru-lamination is formed, and metal antibacterial layer is provided with the inside of vinyon internal layer, and this kind sets and have a small amount of heat
Amount loss, vinyon outer layer can be damaged under climatic effect.
The content of the invention
The purpose of the present invention is there is above mentioned problem for existing technology, it is proposed that a kind of aluminium-plastic pipe, with insulation, every
Hot and corrosion resistant advantage.
The purpose of the present invention can be realized by following technical proposal：A kind of aluminium-plastic pipe, includes inner tube successively from inside to outside
With polyethylene foam heat-insulation layer, inner tube has three-decker, and internal layer and outer layer are pvc pipe, and intermediate layer is aluminum pipe, polyethylene foam
EVA film is provided between layer and inner tube, polyethylene foam heat-insulation layer outer surface is coated with one layer of EVA film.
Further, described polyethylene foam insulation layer thickness is 4-6mm.
Further, the thickness of described internal layer is 1-2mm, and the thickness of outer layer is 1-2mm.
Further, the thickness in described intermediate layer is 0.5-1mm.
Compared with prior art, the advantage of this aluminium-plastic pipe has：
1.EVA films play a protective role, due to EVA film good toughness, prevent polyethylene foam heat-insulation layer from being cut by extraneous hard thing
Split or wear and tear, while also having the effect of insulation.
2. polyethylene foam heat-insulation layer plays function of heat insulation, and with corrosion resistant function, can be used for a long time.
3.PVC pipe prices are relatively cheap, corrosion-resistant, energy-saving.
4. clamping aluminum pipe in two pvc pipes, inner tube is set to possess the firm pressure-resistant and antiacid alkali corrosion-resistant two of metal tube big excellent
Point.
Brief description of the drawings
Fig. 1 is aluminium-plastic pipe structural representation.
In figure, 1, EVA film；2nd, polyethylene foam heat-insulation layer；3rd, internal layer；4th, intermediate layer；5th, outer layer.
Embodiment
The following is specific embodiment of the invention and with reference to accompanying drawing, technical scheme is further described.
As shown in figure 1, the present invention provides a kind of aluminium-plastic pipe, it includes inner tube successively from inside to outside and polyethylene foam is incubated
Layer 2, inner tube has three layers, and internal layer 3 and outer layer 5 are all pvc pipes, and intermediate layer 4 is aluminum pipe, polyethylene foam heat-insulation layer 2 and inner tube it
Between be stained with EVA film 1, the outer surface of polyethylene foam heat-insulation layer 2 is stained with EVA film 1.
Further, the described thickness of polyethylene foam heat-insulation layer 2 is 5mm.
Further, the described thickness of internal layer 3 is 2mm, and the thickness of outer layer 5 is 1mm.
Further, the thickness in described intermediate layer 4 is 0.5mm.
Polyethylene foam layer uses nontoxic, free from extraneous odour plastics for raw material foaming, can prevent the liquid in aluminium-plastic pipe
Body heat content is distributed, and keeps fluid temperature.
The plastic-aluminum pipe reduces heat loss during delivery, EVA film 1 plays a protective role, with good in water heater
Good durability, can resist high temperature, can use for a long time.
Intermediate layer 4 enhances the fastness of aluminium-plastic pipe, and EVA film 1 has good corrosion-resistant, anti-weather performance.
Claims (4)
