Problems solved by technology

[0004] At present, the common fire-resistant cables include mineral insulated fire-resistant cables, silicone rubber insulated fire-resistant cables, mica tape PVC insulated and sheathed fire-resistant cables, etc. The former has low processing efficiency and high cost, while the latter will produce toxic gases when burned, and transmit light. Low efficiency, cannot meet the high stability and high environmental protection requirements of modern halogen-free cables

Abstract

The invention belongs to the field of fire-resistant materials, and particularly relates to a fire-resistant silicone rubber cable material. The fire-resistant silicone rubber cable material is mainly prepared from the following raw materials in parts by weight: 100 parts of phenyl silicone rubber, 6-10 parts of hydroxyl silicone oil, 20-30 parts of white carbon black, 10-15 parts of heavy calcium carbonate, 0.5-1 part of a vulcanizing agent, 2 parts of an anti-ageing agent, 0.3-0.5 part of an accelerant, 0.5-4 parts of a co-curing agent, 15-25 parts of a flame retardant and 2-3 parts of a heat stabilizer. The fire-resistant silicone rubber cable material disclosed by the invention has the advantages of stable fire resistance, high insulating performance and high mechanical performance.

Description

technical field [0001] The invention belongs to the field of refractory materials, and in particular relates to a refractory silicone rubber cable material and a preparation method thereof. Background technique [0002] In recent years, after fires in large public entertainment places, chemical industry, coal mines, and commercial buildings caused tragic loss of people's lives and property, people have a deeper understanding of fire protection and fire safety. With the rapid growth of urban population, the continuous increase of high-rise buildings, hotels, large supermarkets, hospitals, stations, and airports, the construction of subways and tunnel traffic, and the increase of large-scale public sports, entertainment venues, and public transportation facilities, fire prevention and fire prevention The importance of safety is highlighted. How to ensure the smooth flow of power and communication within a certain period of time in the event of a fire, maximize the precious re...
