Abstract
The utility model provides a PP-R plastic-aluminum steady-state tube. The PP-R plastic-aluminum steady-state tube comprises an inner polypropylene layer, an aluminum layer and an outer polypropylene layer; the upper surface and the lower surface of the aluminum layer are provided with a plurality of small holes; the inner polypropylene layer is connected with the small holes in the lower surface of the aluminum layer in an attached mode, and the outer polypropylene layer is connected with the small holes in the upper surface of the aluminum layer in an attached mode. The PP-R plastic-aluminum steady-state tube has the advantages that strength of the PP-R plastic-aluminum steady-state tube is good, and a single-layer PP-R tube is light, safe and reliable in connection, convenient to construct and the like.
Description
Technical field
The utility model relates to PP-R pipe, specifically, relates to a kind of PP-R plastic aluminum steady-state tube.
Background technique
Traditional PP-R(tri-type polypropylene tube) tubing is that outward appearance is white single layer structure, but because individual layer PPR pipe is yielding, rigidity is bad etc., so firmly the portion's of building regulation can only be used for secretly burying laying.
According to China's actual conditions; part house ornamentation pipeline does not secretly bury; on market, there is a kind of composite pipe being combined by PP-R pipe and aluminium; it is to keep on the constant basis of former PP-R pipe specification, adopts at high temperature organic bonding PP-R protective layer covering again about 0.2mm of aluminium strip that hot melt adhesive technology is 0.15-0.25mm at its outer surface and thickness.It has polypropylene-hot melt adhesive-aluminium-hot melt adhesive-polypropylene five-layer structure, and wherein aluminium plays reinforing function.
Existing PP-R steady state pipe is all 5 layers of structure (interior polypropylene layer, internal layer glue, aluminium lamination, outer glue, outer polypropylene layer), easily there are quality problems in the bonding position of PP-R and aluminium lamination wherein, and cover plastic-aluminum combined layer outside peelling off with special volume stripping instrument before hot melt connects, the aluminium lamination that connects rear port position is open, has reduced mechanical strength and the voltage endurance capability of tubing.
Model utility content
In order to overcome above-mentioned technical problem, the utility model provides a kind of simple in structure, aluminium lamination uniform fine and closely woven circular hole around, and inside and outside polypropylene layer is realized seamless link in the time of moulding, and middle aluminium lamination has also obtained PP-R plastic aluminum steady-state tube effectively reliably.
To achieve these goals, a kind of PP-R plastic aluminum steady-state tube described in the utility model, it comprises interior polypropylene layer, aluminium lamination and outer polypropylene layer; Upper and lower two surfaces of described aluminium lamination are provided with some apertures; Some apertures of the lower surface of described interior polypropylene layer and aluminium lamination are fitted and connected, and the aperture of the upper surface of described outer polypropylene layer and aluminium lamination is fitted and connected.
As preferably, described interior polypropylene layer is connected by viscose glue with the aperture of the lower surface of aluminium lamination; Described outer polypropylene layer is connected with the aperture viscose glue of the upper surface of aluminium lamination.
As preferably, 1/2 place of described aluminium lamination in body thickness;
As preferably, described aluminum layer thickness is 0.1mm.
As preferably, described aperture is circular hole and is distributed on upper and lower two surfaces of aluminium lamination.
A kind of PP-R plastic aluminum steady-state tube of one of the present utility model, not only has the good feature of PP-R steady state pipe intensity, has also kept individual layer PP-R pipe light weight, has connected the advantages such as safe and reliable, easy construction.
Accompanying drawing explanation
Fig. 1 is the cross section structure schematic diagram of a kind of PP-R plastic aluminum steady-state tube described in the utility model;
Fig. 2 is the aluminium lamination deployed configuration schematic diagram of a kind of PP-R plastic aluminum steady-state tube described in the utility model.
