Description
Technical Field
The utility model relates to the field of water supply and drainage, in particular to an antifouling aluminum plastic pipe.
Background
The aluminum plastic pipe is a pipe commonly used in the water supply and drainage field, and is used in various industries because of the advantages of good oxygen resistance, light resistance, high temperature resistance, high pressure resistance, no deformation and the like. Especially in the heating industry, the existing floor heating aluminum plastic pipes are firstly arranged on the ground, and then floor tiles are paved on the floor heating pipes for daily use. Because the floor tile is paved to cause the difficulty in the later maintenance and replacement of the floor heating aluminum plastic pipe, the antifouling, antirust and leak-proof performance of the floor heating aluminum plastic pipe needs to be enhanced in order to prolong the service life of the floor heating.
The structure of the existing aluminum plastic pipe commonly adopts an aluminum pipe layer sandwiched between an inner plastic layer and an outer plastic layer. The aluminum tube provides a certain supporting force and oxygen blocking capacity. The plastic layer can increase when being heated and expanded and permeate oxygen molecules into the pipe through the pipe wall, and the metal equipment contacted with water is corroded by water flow, or microorganisms are bred in the water system, and the microorganisms form biological mud on the inner wall of the pipe so as to block the pipe, so that heat cannot be emitted. Therefore, the aluminum tube can also provide a certain oxygen barrier capability. However, when the outer plastic layer is heated and expanded, oxygen molecules permeate to directly contact with the aluminum pipe, so that the aluminum pipe is easily oxidized for a long time, and the oxygen blocking capacity is reduced, and rust occurs. Failure of the plastic-aluminum pipe is also easily caused.
There is an aluminum plastic pipe structure in the prior art that an insulation layer is arranged in or outside the pipe wall of the aluminum plastic pipe so as to prevent the plastic layer from being heated and expanded to cause oxygen permeation increase when heating hot water is transmitted, however, the insulation layer also causes that the heat of the heating hot water cannot be emitted, and the heating effect of the floor heating is reduced.
In addition, the structure of the aluminum plastic pipe is that an EVOH oxygen barrier layer is added outside the pipe, and the oxygen barrier effect is enhanced, but the oxygen barrier layer is easily rubbed off in the coil pipe process, so that the oxygen barrier effect is discounted.

Can effectively prevent the generation of biological sludge in the pipe after the oxygen blocking capacity is improved.
In addition, the wear-resistant outer layer is poor in heat conductivity due to material reasons, the heat conduction metal wire arranged on the wear-resistant outer layer can better emit the temperature inside the pipe, and compared with the existing aluminum plastic pipe, the heat-resistant outer layer has better heat dispersibility, and when the heat-resistant outer layer is used for a floor heating pipe, the heat conduction efficiency is higher.

The PERT inner layer 1 is connected with the aluminum pipe layer 2 through a first adhesive layer 4; an EVOH oxygen barrier layer 5 is arranged on the outer side of the aluminum pipe layer 2, and the aluminum pipe layer 2 is connected with the EVOH oxygen barrier layer 5 through a second adhesive layer 6; the EVOH oxygen barrier layer 5 is connected with the wear-resistant outer layer 3 through a third adhesive layer 7. Thus, the aluminum plastic pipe with four functional layers is formed.
Wherein the PERT inner layer 1 forms a water flow channel. The wear-resistant outer layer 3 is used for protecting the inner structure of the pipe and plays a role in enhancing the wear resistance of the pipe body. The aluminum pipe layer 2 plays roles of supporting the shape of the aluminum plastic pipe, improving the flexibility of the aluminum plastic pipe and blocking oxygen from penetrating inwards. The EVOH oxygen barrier layer 5 is used for protecting the aluminum pipe layer 2 and preventing oxygen molecules from acting on the surface of the aluminum pipe layer 2 to oxidize aluminum when oxygen permeation occurs in the wear-resistant outer layer 3.
The wall thickness of the wear-resistant outer layer 3 is larger than the wall thickness of the PERT inner layer 1, the wall thickness of the EVOH oxygen barrier layer 5 is larger than the wall thickness of the aluminum pipe layer 2.

The antibacterial layer 8 is a nano silver ion antibacterial layer. The antibacterial layer is arranged on the inner wall of the inner tube, so that the blockage of the viscera of the tube caused by microorganisms carried by the water body can be further avoided.
In another embodiment, as shown in fig. 3, the aluminum plastic pipe comprises a heat conducting wire 10 which is wound on the outer side of the wear-resistant outer layer 3 in a net shape in addition to the PERT inner layer 1, the aluminum pipe layer 2, the EVOH oxygen barrier layer 5 and the wear-resistant outer layer 3.
