Description

Technical Field

[0001] The utility model belongs to the technical field of PE pipes, in particular to a PE pipe with toughening performance. Background Art

[0002] PE is polyethylene plastic, which is one of the most basic plastics. Plastic bags, food wraps, etc. are all made of PE.

[0003] As the current mainstream underground and municipal household water pipes, PE pipes need to have the functions of anti-corrosion, waterproofing, and anti-leakage. However, since some parts of the PE pipes need to be buried underground and some are exposed to the external environment, there are many factors to be overcome, which greatly affects the service life of the PE pipes. Content of the Utility Model

[0004] Purpose of the utility model: To provide a PE pipe with toughening performance to solve the above problems existing in the prior art.

[0005] Technical solution: A PE pipe with toughening performance includes a core pipe body, and a protective layer is fixedly installed on the outer side of the core pipe body;

[0006] The protective layer includes an impact-resistant layer, a flexible layer, an anti-corrosion layer, a heat-insulating layer, a waterproof layer, and a water storage layer. The impact-resistant layer is arranged on the outermost side of the core pipe body. The flexible layer, the anti-corrosion layer, the heat-insulating layer, the waterproof layer, and the water storage layer are arranged in sequence and are fixedly connected to each other pairwise. The water storage layer is fixedly connected to the core pipe body.

[0007] In a further embodiment, the material of the impact-resistant layer is polyvinyl chloride.

[0008] In a further embodiment, the flexible layer is closely attached to the impact-resistant layer, and materials such as softeners and silicone oil are added to the flexible layer.

[0009] In a further embodiment, a cured silicone resin material is coated on the surface of the anti-corrosion layer.

[0010] In a further embodiment, asbestos for heat preservation is arranged in the heat-insulating layer, and bituminous paint is poured around the asbestos, and the bituminous paint fills the heat-insulating layer.

[0011] In a further embodiment, a leakage-proof nano material is filled and coated on the surface of the waterproof layer.

[0012] In a further embodiment, the inside of the water storage layer is hollow and has a height of 2 - 3 mm.

[0013] Advantageous Effects:

[0014] The PVC material used for the impact-resistant layer on the outer side of the core pipe body has stronger overall low-temperature resistance. At the same time, the surface of the impact-resistant layer will harden at low temperatures. At this time, the flexible layer supports the impact-resistant layer, providing better shock absorption and compressive resistance for the impact-resistant layer. An anti-corrosion layer is provided below the flexible layer to increase the corrosion resistance of the core pipe body and extend the service life of the core pipe body. At the same time, through the double heat preservation effect of asbestos and bituminous paint in the heat preservation layer, the low-temperature impact on the core pipe body is reduced. At the same time, when the waterproof layer effectively prevents water leakage caused by pipeline rupture, it directly affects the core pipe body, and the water storage layer can collect the infiltrated water and isolate the water from the core pipe body to ensure the normal use of the core pipe body.

[0017] In the following description, numerous specific details are given to provide a more thorough understanding of the present invention.

[0018] However, it will be apparent to those skilled in the art that the present invention may be practiced without one or more of these details.

[0019] In other instances, some well-known technical features are not described in order to avoid obscuring the present invention.

[0020] As Figure 1 shown, a PE pipe with toughening performance is composed of an impact-resistant layer 1, a flexible layer 2, an anti-corrosion layer 3, a heat preservation layer 4, a waterproof layer 5, a water storage layer 6, and a core pipe body 7.

[0021] As Figure 1 shown, a protective layer is fixedly installed on the outer side of the core pipe body 7;

[0022] The protective layer includes an impact-resistant layer 1, a flexible layer 2, an anti-corrosion layer 3, a heat preservation layer 4, a waterproof layer 5, and a water storage layer 6. The impact-resistant layer 1 is arranged on the outermost side of the core pipe body 7. The flexible layer 2, the anti-corrosion layer 3, the heat preservation layer 4, the waterproof layer 5, and the water storage layer 6 are arranged in sequence and fixedly connected to each other pairwise. The water storage layer 6 is fixedly connected to the core pipe body 7.

[0023] The material of the impact-resistant layer 1 is made of polyvinyl chloride. The polyvinyl chloride material can withstand temperatures from -60°C to 60°C. The temperature it can withstand can adapt to the temperature differences in most regions. In some southern regions with relatively small temperature differences, the material of the impact-resistant layer 1 can also be made of ethylene-propylene monomer copolymer, i.e., ethylene-propylene rubber, which has better overall performance than polyvinyl chloride but is not as good as polyvinyl chloride in terms of low-temperature resistance. Therefore, it cannot be promoted in cities with large temperature differences in the north.

[0024] The flexible layer 2 is closely attached to the impact-resistant layer 1, and materials such as softeners and silicone oil are added to the flexible layer 2. By adding materials such as softeners or silicone oil, the flexible layer 2 can be softened, making the flexible layer 2 fit the impact-resistant layer 1 better, providing better protection for the impact-resistant layer 1, and having better supporting force and inclusiveness.

[0025] The surface of the anti-corrosion layer 3 is coated with a cured silicone resin material.

[0026] Asbestos for heat preservation is provided in the heat-insulating layer 4, and bituminous paint is poured around the asbestos, and the bituminous paint fills the heat-insulating layer 4.

[0027] The surface of the waterproof layer 5 is coated with a leak-proof nano material.

[0028] The inside of the water storage layer 6 is hollow and has a height of 2 - 3 mm. When there is a small leak in the above-mentioned protective layer, in the form of drip leakage with a slow leakage speed, after the water enters the water storage layer 6, it can spread to both sides, realizing the storage of a small amount of water, effectively preventing the core pipe body 7 from being directly eroded by external liquids and causing damage to the core pipe body 7.

[0029] The working principle of this utility model is as follows:

[0030] The polyvinyl chloride material used for the impact-resistant layer 1 on the outer side of the core pipe body 7 has stronger overall low-temperature resistance. At the same time, the surface of the impact-resistant layer 1 will harden at low temperatures. At this time, the flexible layer 2 supports the impact-resistant layer 1, providing better shock absorption and compressive resistance for the impact-resistant layer 1. The anti-corrosion layer 3 is arranged below the flexible layer 2 to increase the corrosion resistance of the pipe core body and extend the service life of the pipe core body. At the same time, through the double heat-insulating effects of asbestos and bituminous paint in the heat-insulating layer 4, the low-temperature impact on the core pipe body 7 is reduced. At the same time, when the waterproof layer 5 effectively prevents water leakage caused by pipeline rupture, it can directly prevent the core pipe body 7 from being affected. The water storage layer 6 can collect the infiltrated water and isolate the water from the core pipe body 7 to ensure the normal use of the core pipe body 7.

[0031] The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present utility model, various equivalent transformations can be made to the technical solutions of the present utility model, and these equivalent transformations all belong to the protection scope of the present utility model.
