Description

Technical Field

[0001] This utility model relates to the field of polyethylene pipe technology, and in particular to a high-strength anti-aging polyethylene pipe. Background Technology

[0002] Polyethylene pipe (PE pipe) is a common type of plastic pipe, widely used as a water supply pipe. It is a replacement product for traditional steel pipes and polyvinyl chloride drinking water pipes. Polyethylene pipes are often used in urban water supply and drainage pipelines and are mostly buried underground for long periods of time.

[0003] However, existing polyethylene pipes have low pressure resistance, which can easily lead to pipe rupture in complex soil environments. In addition, existing polyethylene pipes have poor anti-aging properties and are prone to aging with long-term use, which affects the service life of the pipes. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model designs a high-strength anti-aging polyethylene pipe.

[0005] The present invention adopts the following technical solution:

[0006] A high-strength, anti-aging polyethylene pipe includes a polyethylene pipe with an outer pressure-resistant reinforcing layer, an aluminum foil layer outside the pressure-resistant reinforcing layer, and a silicone layer outside the aluminum foil layer. The pressure-resistant reinforcing layer enhances compressive strength, achieving high strength. The aluminum foil is an opaque coating material that effectively shields light and prevents ultraviolet rays, and is also high-temperature resistant and flame-retardant. The silicone layer is oil-resistant, wear-resistant, low-temperature resistant, aging-resistant, and elastic. The combined protective effect of the aluminum foil and silicone layer effectively improves the overall anti-aging performance of the pipe.

[0007] Preferably, the pressure-resistant reinforcing layer consists of a polyurethane layer and a spirally wound steel wire ring, with the spirally wound steel wire ring embedded in the polyurethane layer.

[0008] Preferably, the polyurethane layer and the spirally wound steel wire ring are integrally injection molded using a mold.

[0009] Preferably, the polyurethane layer is made of polyurethane elastomer. Polyurethane elastomers have properties between those of plastics and rubber, including oil resistance, wear resistance, low-temperature resistance, aging resistance, high hardness, and elasticity.

[0010] Preferably, the silicone layer is coated with a PVDF membrane layer. PVDF membrane, or polyvinylidene fluoride membrane, has high mechanical strength and toughness, anti-mildew properties, high wear resistance, high permeability to gases and liquids, good thermal stability, flame retardancy, low smoke, good creep resistance during temperature increases, high purity, easy melt processing, resistance to most chemicals and solvents, a combination of rigid and flexible forms, resistance to ultraviolet and nuclear radiation, impact resistance, weather resistance, and low temperature resistance down to -40℃. Therefore, under the protective effect of the PVDF membrane layer, the overall anti-aging performance of the pipeline can be effectively improved.

[0011] Preferably, the pressure-resistant reinforcing layer is formed by spiral winding of multiple layers of steel strips.

[0012] Preferably, the winding directions of adjacent layers of steel strip in the multi-layer steel strip are opposite.

[0013] Preferably, the angle at which each layer of steel strip is wound is different in the multi-layer steel strip.

[0014] Preferably, the multi-layered steel strips have no bonding properties and can slide.

[0015] Preferably, the surface of the multilayer steel strip is treated with anti-corrosion measures.

[0016] The beneficial effects of this utility model are as follows: This utility model designs a high-strength, anti-aging polyethylene pipe. The pressure-resistant reinforcing layer enhances the compressive strength, achieving high strength. Aluminum foil is an opaque coating material that effectively shields light, prevents ultraviolet rays, and is also high-temperature resistant and flame-retardant. The silicone layer is oil-resistant, wear-resistant, low-temperature resistant, aging-resistant, and elastic. The combination of aluminum foil and silicone layer effectively improves the overall anti-aging performance of the pipe. Attached Figure Description

[0020] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0021] Example: Figure 1As shown, a high-strength, anti-aging polyethylene pipe includes a polyethylene pipe with a pressure-resistant reinforcing layer 2, an aluminum foil layer 3 outside the pressure-resistant reinforcing layer, and a silicone layer 4 outside the aluminum foil layer. The pressure-resistant reinforcing layer enhances the compressive strength, achieving high strength. The aluminum foil is an opaque coating material that effectively shields light, prevents ultraviolet rays, and is resistant to high temperatures and flames. The silicone layer is oil-resistant, wear-resistant, low-temperature resistant, aging-resistant, and elastic. The combined protective effect of the aluminum foil and silicone layer effectively improves the overall anti-aging performance of the pipe.

[0022] The pressure-resistant reinforcement layer consists of a polyurethane layer and a spirally wound steel wire ring, with the spirally wound steel wire ring embedded in the polyurethane layer.

[0023] The polyurethane layer and the spirally wound steel wire ring are integrally injection molded using a mold.

[0024] The polyurethane layer is made of polyurethane elastomer. Polyurethane elastomer has properties between those of plastics and rubber, including oil resistance, abrasion resistance, low-temperature resistance, aging resistance, high hardness, and elasticity.

[0025] The silicone layer is covered with a PVDF membrane. PVDF membrane, or polyvinylidene fluoride membrane, has high mechanical strength and toughness, anti-mildew properties, high wear resistance, high permeability to gases and liquids, good thermal stability, flame retardancy, low smoke, good creep resistance during temperature increases, high purity, easy melt processing, resistance to most chemicals and solvents, a combination of rigid and flexible forms, resistance to ultraviolet and nuclear radiation, impact resistance, weather resistance, and low temperature resistance down to -40℃. Therefore, under the protection of the PVDF membrane layer, the overall anti-aging performance of the pipeline can be effectively improved.

[0026] This invention designs a high-strength, anti-aging polyethylene pipe. A pressure-reinforcing layer enhances compressive strength, achieving high strength. Aluminum foil is an opaque coating material that effectively shields light and blocks ultraviolet rays, while also being high-temperature resistant and flame-retardant. The silicone layer is oil-resistant, wear-resistant, low-temperature resistant, aging-resistant, and elastic. The combination of aluminum foil and silicone layer effectively improves the overall anti-aging performance of the pipe.
