[0025] Reference Figure 1-4 A corrosion-resistant PE composite pipe comprises a pipe body 1, the outer layer of the pipe body 1 is provided with a rubber buffer layer 2, the outer layer of the rubber buffer layer 2 is provided with a first protective layer 4, a water-proof membrane 3 is provided between the buffer layer and the first protective layer 4, a protective layer 5 is provided on the surface of the first protective layer 4, and a second protective layer 6 is provided on the inner wall of the pipe body 1.

[0026] Furthermore, the second protective layer 6 is an epoxy coating, which is coated on the inner wall of the pipe body 1 and cured by ultraviolet radiation. By setting the epoxy coating, its excellent anti-corrosion properties are utilized to block the erosion of oxygen and moisture, thereby extending the service life of the pipe body 1.

[0027] Furthermore, the rubber buffer layer 2 includes a first rubber sleeve 21, a second rubber sleeve 22 and a rubber protrusion 23. The rubber protrusion 23 is evenly arranged between the first rubber sleeve 21 and the second rubber sleeve 22, and the rubber protrusion 23 is integrally formed with the first rubber sleeve 21 and the second rubber sleeve 22. There is a certain gap between two adjacent rubber protrusions 23. By dividing the rubber buffer layer 2 into three parts, the pipe body 1 can be fully protected, and the middle rubber protrusion 23 can use its deformation ability to protect it when it is squeezed or vibrated. The gap between the rubber protrusions 23 can provide sufficient space for its deformation, which is convenient for use.

[0028] Furthermore, the first protective layer 4 is made of wire mesh, and the surface of the wire mesh is coated with anti-rust paint. By setting the wire mesh, protection can be formed on the surface of the pipe body 1, and the rubber buffer layer 2 can also be protected, thereby reducing the possibility of scratches on the rubber buffer layer 2 and the pipe body 1 itself during the transportation of the pipe body 1.

[0029] Furthermore, the protective layer 5 is a PVD coating, which is formed on the surface of the substrate by physical evaporation technology. This coating can enhance the wear resistance, corrosion resistance and scratch resistance of the surface, increase the glossiness and hardness of the material surface, thereby improving the cleanability of the material surface. Even if impurities are attached to the surface, they can be easily cleaned, reducing the corrosion of corrosive debris to the pipeline.

[0030] Furthermore, the waterproof membrane 3 is made of a thermoplastic polyurethane film, which has a waterproof function and a certain elasticity. Therefore, when the rubber buffer layer 2 is deformed by force, the thermoplastic polyurethane film will also deform with its own elasticity, and the waterproof membrane 3 will not be damaged.

[0031] In summary, by setting the rubber buffer layer 2, the pipeline body 1 can be provided with a buffering and protective function, and the rubber buffer layer 2 is set to three layers to improve its protection effect. The provided waterproof membrane 3 and wire mesh cloth can protect the rubber waterproof layer, reduce the damage caused by external sharp objects to the rubber waterproof layer and the pipeline body 1, and at the same time reduce the corrosion of the rubber buffer layer 2 by external sewage, effectively improving the service life of the pipeline body 1.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
