Problems solved by technology

On the other hand, termite insects will eat away at the cable sheath, thus causing a great safety hazard to the use of cables. Therefore, anti-termite cable materials are used in the industry to prevent termites from gnawing
At present, the most effective anti-termite cable material is nylon 12, but the price of nylon 12 is quite expensive, usually more than 300 yuan/kg; when nylon 12 is used to produce cables, extrusion molding is usually used, and nylon 12 is put into extrusion molding. In the furnace of the plastic machine, it is melted by shearing, compression, and heating,

Abstract

The invention relates to the technical field of wires and cables and in particular relates to an anti-termite cable material. The cable material is characterized by being prepared from the following raw materials in parts by weight: 30-40 parts of ethylene-tetrafluoroethylene copolymer, 30-40 parts of propylene-tetrafluoroethylene copolymer, 12-18 parts of glass fibers, 2-4 parts of magnesium hydroxide, 2-4 parts of mica powder, 2-4 parts of carbon black or titanium dioxide, 1-3 parts of bifenthrin and 3-5 parts of methylbenzene. The invention further discloses a manufacturing method of the cable material. The cable material mainly has the beneficial effects of being outstanding in anti-termite and anti-mouse performance and excellent in anti-ultraviolet-aging performance, has the advantages of being high in electrical insulativity, relatively heat-resistant, relatively corrosion-resistant, relatively steam-resistant, relatively oil-resistant, relatively fire-resistant, relatively flame-retardant, relatively high in mechanical strength and the like, and is easy to manufacture; the production speed is relatively high and the thickness can be accurately controlled when the cable material is used for producing the wires and the cables.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an anti-ant cable material and a cable using the material. Background technique [0002] Most of the cables used in areas with large forest areas need to have the function of anti-ants. Since most ants can secrete formic acid, especially termites, ants are very corrosive to the sheath of cables. On the other hand, termite-like insects will eat away at the cable sheath, thus causing a great safety hazard to the use of cables. Therefore, anti-termite cable materials are used in the industry to prevent termites from gnawing. At present, the most effective anti-termite cable material is nylon 12, but the price of nylon 12 is quite expensive, usually more than 300 yuan / kg; when nylon 12 is used to produce cables, extrusion molding is usually used, and nylon 12 is put into extrusion molding. In the furnace of the plastic machine, it is melted by shearing, compression, and heating, and...
