Abstract
The utility model discloses an external fused-type composite aluminum and plastic pipe including a random copolymerized polypropylene extruded plastic layer; the inner surface of the layer is connected with a fused bond layer, the inner surface of the bond layer is connected with an aluminum pipe layer, the inner surface of the pipe layer is connected with a fused bond layer, and the inner surface of the bond layer is connected with the polypropylene extruded plastic layer; the utility model is designed with the excellent high-temperature resistant function and the function of little deformation when being heated of composite aluminum and plastic pipe and the reliability of the fused connection of the PP-R pipe materials, therefore, this model could be widely used in these fields such as hot and cold water tap and drinking water system, heating line, floor board, wall, heating system, solar heating and cooling system, industrial fluid transmission system, central air-conditioning system, compressed air line, etc.
Description
Technical field:
The utility model relates to a kind of plastic tube, especially a kind of outer welded-connecting type aluminium-plastic composite pipe that is commonly called as plastic-aluminum PP-R pipe.
Background technique:
PP-R is to being three type polypropylene tube again, it is a kind of architectural plastic delivery hose road that is widely used in, it has advantages of good anticorrosion performance, good shock resistance and long-term creep performance, in light weight except having general plastic tube, corrosion-resistant, non-scaling, outside the characteristics such as long service life, also have nontoxic, the characteristics of health, and it adopts hot melt to connect, connect reliably, the joint is easy to leak not, but there is the lower shortcoming of intensity in this tubing, there is certain low temperature brittleness below 5 ℃, be not suitable for the bigger occasion of ask for something intensity, and its expansion coefficient is big, the easy deformation of being heated; At the low problem of intensity that the PP-R pipe exists, having occurred a kind of advantage that collects metal tube and plastic tube on the market is the novel tube of one, i.e. aluminium-plastic composite pipe (PAP).This aluminium-plastic composite pipe has the characteristics of plastic tube and metal tube concurrently.Not only have characteristics such as corrosion-resistant, non-scaling, long service life, and the intensity height, resistance to high temperature is good, temperature distortion is little, but aluminium-plastic composite pipe is owing to adopt pipe fitting to connect, joint cost height, and connect insecure, the easy seepage in joint.
Summary of the invention:
The purpose of this utility model is: provide a kind of intensity good, be connected firmly and the outer welded-connecting type aluminium-plastic composite pipe of easy to leak not, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises the outer field atactic copolymerized polypropene coextrude bed of material (1), internal surface at the atactic copolymerized polypropene coextrude bed of material (1) is connected with hot melt adhesive layer (4), internal surface in hot melt adhesive layer (4) is connected with aluminum tube layer (3), internal surface at aluminum tube layer (3) is connected with hot melt adhesive layer (5), is connected with the polyethylene coextrude bed of material (2) at the internal surface of hot melt adhesive layer (5).
The atactic copolymerized polypropene coextrude bed of material (1) adopts the Vestolen P 9421 polypropylene random copolymer pipeline raw materials of SABIC Europe petro-chemical corporation to be made.
The polyethylene coextrude bed of material (2) adopts the DX800 of SK Ltd. heat-proof polythene PE-TR material to form.
Hot melt adhesive layer (4) adopts the powerful PP-R hot melt adhesive of Mitsui QF551 company.
Hot melt adhesive layer (5) adopts the LG AP150 of Co., Ltd. high-strength polyethylene hot melt adhesive.
The utility model combines the advantage of aluminium-plastic composite pipe and PP-R tubing, it is good to have sanitation performance, avirulent, high temperature high voltage resistant, corrosion-resistant, non-scaling, anti-aging, anti-creep, advantages such as long service life, have the hard of metal, be easy to bending again and stretch, and do not rebound, good toughness, it has good resistance to high temperature of aluminium-plastic composite pipe and the little characteristics of temperature distortion concurrently simultaneously, the reliability that is connected with PP-R tubing hot melt, adopt hot melt or electric smelting to connect, the intensity of its connection part is greater than the intensity of tubing itself, traditional aluminium-plastics composite pipe joint cost height and the shortcoming that is connected weak effect had both been solved, solved the shortcoming of the big and low temperature brittleness of PP-R tubing coefficient of linear expansion again,, can be widely used in cool and hot water pipe and potable water system, caliduct, the floor, wall, heating system, solar energy heating, cooling system, the industrial fluids transporting system, central air-conditioning system, fields such as compressed air line system.
