[0003] In the related art, the raw materials for cables are mostly ordinary PVC cable materials, which have poor corrosion resistance and wear resistance. When the cables are in an outdoor environment, especially in a hot and humid or acidic environment, they are easily corroded, causing the aging of the line, resulting in The service life of the cable is greatly shortened, and it is easy to cause the failure of the transmission line, which brings great inconvenience to the surrounding residents and also causes great losses to the power department.
When electric maintenance personnel overhaul the circuit, if there is cable corrosion and aging and leakage, it will also lead to potential safety hazards in the operation process of electric maintenance personnel, which will inevitably lead to an increase in their workload
[0004] In view of the above-mentioned related technologies, the inventor believes that in practical applications, cables are easily corroded and aged due to the influence of acidic environment, and the corrosion resistance of cables needs to be improved

Abstract
The invention relates to the technical field of wires and cables, and particularly discloses an anti-corrosion cable and a preparation method thereof. The anti-corrosion cable comprises the followingcomponents in parts by weight: polypropylene resin, diglycolamine, modified nano silicon dioxide, aluminum hydroxide, a plasticizer, an antioxidant, silicone oil, and the maleic anhydride is grafted with an ethylene-vinyl acetate copolymer. The preparation method comprises the following steps: mixing the polypropylene resin, the modified nano silicon dioxide and the aluminum hydroxide to obtain amixture A, adding diglycolamine into the mixture A, mixing to obtain a mixture B, adding an antioxidant, a plasticizer, a maleic anhydride grafted ethylene-vinyl acetate copolymer and silicone oil into the mixture B, continuously mixing to obtain a mixture C, extruding and granulating the mixture C to obtain a cable material, melting and extruding the cable material, and coating the surface of thewire with the cable material to obtain the corrosion-resistant cable. The anti-corrosion cable can be used in an acid environment, and has the advantage of reducing cable corrosion.
Description
technical field [0001] The present application relates to the technical field of electric wire and cable, more specifically, it relates to an anti-corrosion cable and a preparation method thereof. Background technique [0002] With the development of my country's petrochemical, communication, transportation, construction, electric power and other industries, the demand for cables in power plants, substations, smelting and petrochemical industries has been huge in recent years. Wires and cables are used in more and more fields, and the requirements for their load capacity and working hours are getting higher and higher. Many wires and cables need to be exposed to the outdoors and work in harsh environments, so the materials used for wires and cables The performance requirements are very strict, and it must have the advantages of corrosion resistance, high temperature resistance and flame retardancy. [0003] In the related art, the raw materials for cables are mostly ordinar...
