Embodiment 1

[0023] Mix 25g of epoxy resin and 5g of polymethylsilicone resin at a temperature of 100°C to obtain a modified epoxy resin; mix 10g of nano-silicon carbide, 35g of polyethylene resin, and the above-mentioned modified epoxy resin Resin, 7g of carbon powder, 7g of nickel powder and 1g of anti-ultraviolet agent are placed in an environment with a temperature of 200°C, mixed and smelted, and then extruded to form a skin. The above-mentioned skin is coated with copper wire to form a braided wire, and then Weave a plurality of braided wires to form a high-temperature-resistant wave-proof sleeve A1 with a braiding density of not less than 80%.

Embodiment 2

[0025] 24g of epoxy resin and 16g of polyethylsilicone resin were mixed under the condition of 150°C to obtain a modified epoxy resin; 10g of nano-silicon carbide, 45g of polyethylene resin, and the modified epoxy Resin, 9g of carbon powder, 9g of nickel powder and 1.5g of anti-ultraviolet agent are mixed and smelted in an environment with a temperature of 400°C, and then extruded to form a skin, and the skin prepared above is coated with copper wire to form a braided wire. Then, a plurality of braided wires are braided to form a high-temperature-resistant wave-proof sleeve A2 with a braiding density of not less than 80%.

Embodiment 3

[0027] Mix 24g of epoxy resin and 12g of polymethylsilicone resin under the condition that the temperature is 120°C to obtain a modified epoxy resin; mix 10g of nano-silicon carbide, 40g of polyethylene resin, and the above-mentioned modified epoxy resin Resin, 8g of carbon powder, 8g of nickel powder and 1g of anti-ultraviolet agent are mixed and smelted in an environment with a temperature of 300°C, and then extruded to form a skin, and the above-mentioned skin is coated with copper wire to form a braided wire, and then Weave a plurality of braided wires to form a high-temperature-resistant wave-proof sleeve A3 with a braiding density of not less than 80%.

Abstract

The invention discloses a high-temperature-resistant wave-proof sleeve. The wave-proof sleeve is formed by a plurality of braiding lines through braiding, wherein each braiding line comprises a line core and a skin adhered to the surface layer of the line core, and the skin comprises nano-silicon carbide, polyethylene resin, modified epoxy resin, carbon powder and nickel powder, wherein relative to 10 parts of the nano-silicon carbide by weight, the content of the polyethylene resin by weight is 30-50 parts by weight, the content of the modified epoxy resin is 20-50 parts by weight, the content of the carbon powder is 5-10 parts by weight and the content of the nickel powder is 5-10 parts by weight. By adhering the skin prepared by using the nano-silicon carbide, polyethylene resin, modified epoxy resin, carbon powder and nickel powder in a mixing manner to the surface layers of the braiding lines in the design, the wave-proof sleeve produced by adopting the material and the method is enabled to realize high-temperature-resistant performance while having a good shielding effect, thus better using performance is achieved, the service life is prolonged and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the field of wire and cable materials, in particular to a high-temperature-resistant wave-proof sleeve. Background technique [0002] During the use of wires and cables, anti-wave sleeves are mainly used to prevent radio wave interference or as components that exist as protective sleeves, and play an extremely important role in wires and cables. However, the use environment of wires and cables often leads to high temperature due to long-term use, which greatly reduces their performance, especially the shielding performance during use, reducing the service life of the cable, which not only increases maintenance costs and replacement costs, In some cases, it may also cause certain security risks. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide a high-temperature-resistant wave-proof sleeve with good heat resistance, better shielding effect, which can greatly increase the service life ...
