Abstract
The utility model discloses a meshed aluminium tape enhanced PP-R (PolyPropylene-Random) plastic-aluminium composite pipe, comprising an inner plastic layer, an aluminium tape layer and an outer plastic layer. The inner plastic layer and the aluminium tape layer, and the outer plastic layer and the aluminium tape layer are bonded to each other through hot melt adhesive layers; and a through hole is formed on the aluminium tape layer. The pipe of the utility model is characterized in that the through hole is formed on the aluminium tape layer of the traditional PP-R plastic-aluminium composite pipe; in this way, the outer plastic layer is organically riveted, through melting, to the inner plastic layer through the through hole on the aluminium tape layer, so that the inner plastic layer, the outer plastic layer and the aluminium layer are connected integrally in a connection manner of bonding and riveting, thereby bearing pressure together without causing layering easily; furthermore, due to the special connection manner, the pipe material is capable of being subjected to hot melt connection with a PP-R pipe by using the same tool and the same process. In short, the meshed aluminium tape enhanced PP-R plastic-aluminium composite pipe is suitable to pipes.
Description
Technical field
The utility model relates to tubing, particularly relates to a kind of mesh aluminium strip and strengthens the PP-R aluminium plastic composited tube.
Background technique
Before the utility model proposes, PP-R plastic-aluminum stationary composite pipe has that thermal expansion coefficient is low, high temperature deformation resistance and advantage such as withstand voltage properties is better, the hot melt attachment security is reliable, is the desirable tubing of building hot water and central air-conditioner pipe-line system.But for guaranteeing join strength, this PP-R plastic-aluminum stationary composite pipe need adopt special tool to be connected carrying out hot melt with the PP-R pipe fitting again after tubing is outer and aluminium lamination is peelled off, and it is not too convenient to operate, and also is not easy to universal use; Simultaneously, since between inner plastic layer and aluminium strip layer and outer plastic layer and the aluminium strip layer for bonding mode is connected, so in actual production and using process, occur the phenomenon of layering easily.
The model utility content
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, to provide a kind of instrument and technology that can be identical with the employing of PP-R pipe fitting to carry out the mesh aluminium strip enhancing PP-R aluminium plastic composited tube that hot melt is connected and is difficult for layering.
In order to realize above purpose, a kind of mesh aluminium strip that the utility model provides strengthens the PP-R aluminium plastic composited tube, comprise inner plastic layer, aluminium strip layer and outer plastic layer, bonding by heat-fusing glue layer between described inner plastic layer and aluminium strip layer and outer plastic layer and the aluminium strip layer, described aluminium strip layer is provided with through hole.
In the such scheme, the diameter of described through hole is 0.8～3.5mm, the centre distance of adjacent through-holes is 2～8mm, the thickness of described aluminium strip layer is 0.1～0.5mm, like this, both guaranteed the original combination property of PP-R plastic-aluminum stationary composite pipe, guaranteed again that inner plastic layer, aluminium strip layer and outer plastic layer were difficult for layering, simultaneously, this tubing can adopt identical instrument to carry out hot melt with technology with the PP-R pipe fitting to be connected.
In the such scheme, described inner plastic layer is 0.5～1.5: 1 with the thickness ratio of outer plastic layer, guarantees that further this tubing can adopt identical instrument to carry out hot melt with technology with the PP-R pipe fitting and be connected.
The utility model is provided with through hole on the aluminium strip layer of existing PP-R plastic-aluminum stationary composite pipe, like this, outer plastic layer see through through hole on the aluminium strip layer and inner plastic layer organically fusion be riveted together, inner plastic layer, outer plastic layer and aluminium strip layer are held together by the Placement of " bonding+riveted joint ", common pressure-bearing is difficult for layering; Simultaneously, because this special Placement, this tubing can the instrument identical with the employing of PP-R pipe fitting carries out hot melt with technology and is connected.
The utility model is compared with the prior art, show that fully its superiority is: both kept the original combination property of PP-R plastic-aluminum stationary composite pipe, and the inner plastic layer of this tubing, aluminium strip layer and outer plastic layer are difficult for layering, simultaneously, can adopt identical instrument to carry out hot melt with technology with the PP-R pipe fitting again be connected.
Description of drawings

Fig. 2 is the side-looking structural representation of Fig. 1.
Among the figure: inner plastic layer 1 aluminium strip layer 2 outer plastic layer 3 heat-fusing glue layers 4 through holes 5.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.
The utility model provides a kind of mesh aluminium strip to strengthen the PP-R aluminium plastic composited tube, comprise inner plastic layer 1, aluminium strip layer 2 and outer plastic layer 3, bonding by heat-fusing glue layer 4 between described inner plastic layer 1 and aluminium strip layer 2 and outer plastic layer 3 and the aluminium strip layer 2, described aluminium strip layer 2 is provided with through hole 5.
The diameter of above-mentioned through hole 5 is 0.8～3.5mm, the centre distance of adjacent through-holes 5 is 2～8mm, the thickness of described aluminium strip layer 2 is 0.1～0.5mm, like this, both guaranteed the original combination property of PP-R aluminium plastic composited tube, guaranteed that again inner plastic layer 1, aluminium strip layer 2 and outer plastic layer 3 are difficult for layering, simultaneously, this tubing can adopt identical instrument to carry out hot melt with technology with the PP-R pipe fitting to be connected.Described inner plastic layer 1 is 0.5～1.5: 1 with the thickness ratio of outer plastic layer 3, guarantees that further this tubing can adopt identical instrument to carry out hot melt with technology with the PP-R pipe fitting and be connected.
Making method of the present utility model is: extrude plastic tube (inner plastic layer 1) in the PP-R with an extruder earlier, at high temperature pass through the bonding aluminum pipe of pressing mode (aluminium strip layer 2) with hot melt adhesive then, extrude the outer plastic tube (outer plastic layer 3) of PP-R with another extruder again; In extruding compound process, outer plastic layer 3 is undertaken bonding with aluminium strip layer 2 by High-temp.-resistant hot-melt adhesive, the through hole 5 that while outer plastic layer 3 penetrates on the aluminium strip layer 2 fuses with inner plastic layer 1, like this, the Placement by " bonding+riveted joint " makes inner plastic layer 1, aluminium strip layer 2 and outer plastic layer 3 compound as a whole.
The utility model makes inner plastic layer 1, aluminium strip layer 2 and outer plastic layer 3 compound as a whole by the Placement of " bonding+riveted joint ", common pressure-bearing, not stratified, and can adopt identical instrument to carry out hot melt with technology with the PP-R pipe fitting be connected, both keep PP-R pipe hot melt and connected non-leakage advantage, have the premium properties of PP-R plastic-aluminum stationary composite pipe again, easy for installation, heatproof, good pressure-resistant performance.
