Description

technical field [0001] The invention relates to the technical field of cable sheath materials, in particular to a corrosion-resistant, flame-retardant and heat-resistant cable sheath material. Background technique [0002] Nowadays, cables often need to be buried underground, and now the cable sheath must not only have extremely high withstand voltage strength, but also have a high mechanical index, and at the same time have high corrosion resistance. Fiber reinforced plastics are often used as cable sheaths. Set of materials. Fiber-reinforced plastics generally refer to reinforced plastics that use unsaturated polyester resin, epoxy resin or phenolic resin as the matrix and glass fiber or other fiber products as reinforcement materials. Fiber-reinforced plastics have the advantages of being light and hard, non-conductive, high mechanical strength, less recycling, and corrosion-resistant. Due to the different types of resin matrix used in fiber-reinforced plastics, there a...
