Anti-termite cable material, anti-termite cable using same and anti-termite optical cable

Abstract

The invention relates to the technical field of cables, in particular to an anti-termite cable material. The anti-termite cable material is characterized by being manufactured with, by weight, 40 parts of ethylene-tetrafluoroethylene copolymer, 40 parts of propene-tetrafluoroethylene copolymer, 18 parts of glass fiber, 4 parts of magnesium hydroxide, 4 parts of mica powder, 4 parts of carbon black or titanium dioxide, 3 parts of bifenthrin and 5 parts of methylbenzene. The invention further discloses a manufacturing method and a cable and an optical cable using the material. The cable material has the main advantages of being outstanding in anti-termite and mouseproof performance, excellent in ultraviolet radiation aging resisting performance, high in electrical insulating property, more fireproof and higher in mechanical strength, and resisting heat, corrosion, steam, oil and flame more; the cable material is easy to manufacture, the production speed is higher when the cable material is used for producing cables, and the thickness can be controlled more accurately.

Description

[0001] This application is a divisional application for an invention patent named: An anti-ant cable material and a cable using the material, with the application date: May 26, 2014, and the application number: 201410224420.8. technical field [0002] The invention relates to the technical field of cables, in particular to an anti-ant cable material and an anti-ant cable and an optical cable using the material. Background technique [0003] 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 qui...

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, and then extruded on the cable core. Nylon 12 is very thin after melting, and it is difficult to form on the cable core during extrusion. The production speed is less than 8 m / min. Even at such a low speed, it is difficult to control the thickness of the nylon layer extruded on the cable core. When it is thick, it is usually achieved by multiple extrusions, which greatly increases the production cost

In addition, the nylon 12-pole layer has yellowing phenomenon, and the finished cable, the nylon layer is easy to yellow, which affects the appearance characteristics of the product
