Formula for cable sheath used at bottom of sea

Abstract

The invention discloses a formula for a cable sheath used as the bottom of the sea. According to the formula, the cable sheath is prepared from, by weight, 20-30 parts of polyvinyl chloride, 30-40 parts of SG-3 resin, 5-7 parts of barium stearate, 6-8 parts of halogen-free flame retardant, 4-8 parts of antismoke agent, 5-7 parts of saponite, 2-6 parts of color master batch, 8-12 parts of shock resistance modifying agent, 7-9 parts of ethylene-propylene diene copolymer, 6-10 parts of compound stabilizer and 4-10 parts of silicone master-batches. The cable sheath has the advantages of being good in waterproof effect, long in service life and the like.

Description

technical field [0001] The invention relates to a cable formula, in particular to a formula for a submarine cable sheath. Background technique [0002] At present, with the development of science and technology, more and more cables are used, so people's requirements for cables are getting higher and higher. Because of the inappropriate matching of traditional cable materials, cables work in some humid environments. When it is used, it is easy to cause water to enter the inside of the cable, resulting in a short circuit of the equipment, which brings great problems to people's use. Contents of the invention [0003] In order to overcome the above-mentioned defects of the prior art, the object of the present invention is to provide a formula for submarine cable sheathing. [0004] The present invention is realized by adopting the following technical solutions: a formula for cable sheaths for submarine use, the parts by weight of each component in the formula are as follows...
