Abstract
The utility model relates to an aluminium mesh enhanced aluminum-plastics compound pipe, which comprises an external plastic layer, a hot melt adhesive external bonding layer, a middle aluminum skeleton layer, a hot melt adhesive internal bonding layer and an internal plastic layer are congruent, characterized in that sieve pores are opened on the middle aluminum skeleton layer, the hot melt adhesive internal bonding layer and the hot melt adhesive external bonding layer are capable of passing the sieve pores or meshes, thereby the two hot melt layers are connected mutually, and adhesion strength of interlayer structure is reinforced. Hydrostatic stress and radial withstand voltage strength of the five layers structure pipe of the utility model are obviously higher than the strength of prior five layers structure aluminum-plastics compound pipe, and the utility model is capable of being used in piping systems used in civil or engineering building such as cold and hot water supply, floor heating, gas transmission and solar energy and the like.
Description
Technical field
The utility model relates to the aluminium-plastic composite pipe that a kind of aluminium net strengthens.
Background technique
As everyone knows, aluminium-plastic composite pipe has many advantages, it combines the strong point of metal and plastics, have high-low temperature resistant, withstand voltage, corrosion-resistant, light weight, high-strength, advantages such as anti-gas osmosising, and because the ductility of aluminum alloy is good, also flexiblely do not rebound, therefore, risen since country forbids Coating Steel Pipe is used for feedwater piping since on June 1st, 2000, aluminium-plastic composite pipe has become one of main alternative tubing.Aluminium-plastic composite pipe is made up of five-layer structure, comprises inside and outside PE (or PEX) plastic layer, the inside and outside heat-fusing glue layer that middle aluminium lamination and inside and outside PE (or PEX) plastics and aluminium bond together.Five layers of compound tightness degree, especially aluminium lamination and two affine bonding intensity of hot melt are the key issues that influence the aluminium-plastic composite pipe quality.Aluminium lamination in the middle of the at present domestic existing aluminium-plastic composite pipe is a flat aluminium strip, adopt the ultrasound lap welding or adopt the argon arc butt joint to be welded into pipe, the problem that is exposed through carrying out in the aluminium-plastic composite pipe in recent years, (coming unstuck) often appears separating between such pipe aluminium lamination and two heat-fusing glue layers, especially it is more serious to produce cold delamination in the DN40-63mm heavy caliber aluminium-plastic composite pipe, be that aluminium-plastic composite pipe is after having placed a period of time, the pipe layer comes unstuck with aluminium lamination in taking place, and such problem can't see touch less than, also being difficult to carrying out flaw detection comes out, promptly enable to detect, also can't correct, fatal problem that existing aluminium-plastic composite pipe applies that Here it is.
Summary of the invention
The purpose of this utility model task provides a kind of aluminium-plastic composite pipe with sieve aperture aluminium framework layer, has solved the fatal problem that exists in the existing aluminium-plastic composite pipe.
For achieving the above object, structural feature of the present utility model is with the flat rubber belting aluminium framework layer in the plastic composite of existing five-layer structure, be designed to aluminium framework layer with the sieve aperture structure, it is the aluminium-plastic composite pipe that described aluminium net strengthens, by adhesive layer in the outer adhesive layer of outer plastic layer, hot melt adhesive, middle aluminium framework layer, the hot melt adhesive, inner plastic layer is superimposed constitutes, be characterized in offering equally distributed sieve aperture on the aluminium framework layer in the middle of described.
Sieve diameter 1.0mm～2.5mm in the middle of described on the aluminium framework layer, each adjacent sieve aperture centre distance is 1.5mm～3.5mm.
Compared with prior art, have following characteristics: the aluminium-plastic composite pipe that the utility model aluminium net strengthens, middle skeleton aluminium lamination is aluminium cover (circle) pipe with sieve aperture structure, described aluminum casing is that the aluminium strip that has sieve aperture adopts the ultrasound lap welding or adopts the argon arc butt joint to be welded into, so just make interior heat-fusing glue layer, can lead to (wearing) between the external hot melting glue-line and cross the sieve aperture that gathers with on the sieve aperture aluminium framework layer, and be connected together each other, heat-fusing glue layer in making, the molecular bond of external hot melting glue-line is more introduced polar group, therefore molten state with in, outer layer plastic has better wellability, (OH) the formation chemical bond is more stable for hydroxyl in the patina on its polar group and aluminum metal surface on the other hand, so just make five-layer structure reinforce adhesion, simultaneously because two-layer hot melt adhesive is actually continuous, make and not only adhesive-layer is being arranged vertically, and adhesive-layer has also been arranged at radially (between the aluminium lamination sieve aperture), like this to good binding intensity is more arranged between plastics and aluminium lamination, can also on macroscopic view, enlarge the deficiency that compensation plastics and aluminum steel expand and do not wait, make adhesive layer more be elasticity, make glue-line and mould aluminium and be not stripped from, thereby improved the ring stress of al-plastics composite pipe and compressive strength radially greatly.
Description of drawings
Embodiment of the present utility model is shown among the figure:
Fig. 1 is embodiment's schematic representation of the present utility model, outer adhesive layer 5. outer plastic layers 6. sieve apertures of adhesive layer 3. aluminium framework layers 4. hot melt adhesive in 1. inner plastic layers, 2. hot melt adhesive among the figure
Specific embodiments
In conjunction with the embodiments the utility model aluminium net being strengthened aluminium-plastic composite pipe is described in further detail.
Accompanying drawing 1 has schematically shown the structure of the aluminium-plastic composite pipe of aluminium net enhancing
The five-layer structure of aluminium-plastic composite pipe of the present utility model all is the same with the prior art aluminium-plastic composite pipe with the preparation method, by the whole tubing that five-layer structure is linked to be, five-layer structure is respectively adhesive layer 2 in inner plastic layer 1, the hot melt adhesive, aluminium framework layer 3, the outer adhesive layer 4 of hot melt adhesive and outer plastic layer 5.Different is, offer equally distributed sieve aperture 6 on the aluminium framework layer 3, the preparation method of the aluminium framework layer 3 of this band sieve aperture 6 is: adopting by wall thickness is the aluminium flake (its width adopts corresponding different width according to different size tubing) of 0.25mm～1.0mm, offer equally distributed sieve (net) hole 6 earlier, the aperture of sieve aperture 6 is 1.0mm～2.5mm, each sieve (net) hole centre distance is the uniform layout of 1.5mm～3.5mm, adopt ultrasound lap welding or argon arc butt welding then, make aluminium sleeve (pipe), aluminium framework layer 3 in the middle of being.According to current technology five-layer structure is linked to be a whole tubing again.
Outer plastic layer 5 is a polyethylene layer, or the crosslinked polyethylene layer, or the atactic copolymerized polypropene layer, and outer plastic layer 1 is a polyethylene layer, or the crosslinked polyethylene layer, or the atactic copolymerized polypropene layer.
The aluminium framework layer is the aluminum casing that has the sieve aperture structure in the middle of of the present utility model, adhesive layer, the outer adhesive layer of hot melt adhesive can be worn sieve (net) hole on (leading to) mistake aluminum casing in the hot melt adhesive, make these two heat crucible zones link to each other each other, form an overall structure, reinforced the adhesion intensity of interlayer structure, made five-layer structure tubing intensity that the utility model forms intensity apparently higher than existing aluminium-plastic composite pipe.Can be widely used in civilian or pipe-line systems such as hot and cold feedwater, floor heating, combustion gas conveying and solar energy that engineering construction is used in.
