Formula and preparation method of flame-retardant anticorrosive cable sheath

Abstract

The invention discloses a formula of a flame-retardant anticorrosive cable sheath. The flame-retardant anticorrosive cable sheath comprises, by weight, 5-25 parts of ethylene-butylene rubber, 5-25 parts of hydrogenated butadiene-acrylonitrile rubber, 5-25 parts of polystyrene resin, 5-25 parts of EVA (ethylene vinyl acetate copolymer) resin, 4-12 parts of vulcanizer, 5-15 parts of surfactant, 3-13 parts of carbon black master batches, 4-16 parts of accelerant, 2-10 parts of epoxidized soybean oil, 3-11 parts of hydroxyl silicone oil, 5-15 parts of polyvinylidene chloride and 2-8 parts of nano calcium carbonate. The formula has the advantages of good flame retardance effect, good high-temperature resistance performance, good corrosion resistance performance and the like.

Description

technical field [0001] The invention relates to the field of cables, in particular to a flame-retardant and corrosion-resistant cable sheath formula and a preparation method thereof. Background technique [0002] At present, wires and cables have been widely used in industrial production, transportation, construction engineering and facilities, even in the high-end fields of space and ocean, and cables will be used. With the development of social economy, the varieties of cables are constantly updated and improved, and the production volume It is also increasing continuously. Because of the application of cables in different fields, people's requirements for them are also increasing. The existing cables cannot meet the needs of the industry due to material or structural problems. In some high-temperature environments, common The cable is not able to work normally, and it is easy to cause the internal structure of the cable to be unstable due to high temperature, which makes ...

The existing cables cannot meet the needs of the industry due to material or structural problems. In some high-temperature environments, common The cable is not able to work normally, and it is easy to appear that the internal structure of the cable is unstable due to high temperature, and the signal transmission is distorted.
