Problems solved by technology

[0002] Cables are often used in power systems, industrial and agricultural production, etc. The cables include core conductors, insulating materials and high temperature resistant layers. The core conductors in the cables will cause internal core effects due to long-term current-carrying heat. reduce, and the influence of the external environment will lead to the aging of the external high-temperature resistant layer, which will cause fires and other situations, which will have a greater impact on people. Therefore, the existing technology needs further improvement

Abstract

The invention belongs to the field of cable material processing, and particularly relates to high-temperature-resistant rubber and a cable high-temperature-resistant layer prepared from the high-temperature-resistant rubber. The high-temperature-resistant rubber is prepared from the following raw materials in parts by weight: 100-120 parts of epoxidized methyl vinyl polysiloxane, 60-70 parts of white carbon black, 10-20 parts of vinyl hydroxyl silicone oil, 2-4 parts of a release agent, 7-9 parts of ferric oxide, 1.5-3.5 parts of methyl vinyl MQ silicon resin, 3-5 parts of trimethylsiloxy p-terminal polymethylhydrosiloxane, 0.5-2 part of ethynyl cyclohexanol, 60-85 parts of vinyl-terminated dimethyl methyl vinyl, and 0-15 parts of platinum (O)-1, 3-diethylene-1, 1, 3, 3-tetramethyldisiloxane. Normal work of the wire core can still be ensured at about 320 DEG C.
