AI Technical Summary

Problems solved by technology

Because the cable of this structure requires special production and processing equipment, the capital investment is too large, the cost is high, and it is limited to a certain extent in practical application, and it is difficult to lay and install, and the cost of raw materials is relatively high.
For fire-resistant cables wrapped with mica tape, the mica tape becomes brittle after fire and is easy to fall off, which also results in poor fire-resistant effect, making it difficult to ensure safe and smooth communication and power in case of fire.

Abstract

The invention relates to a refractory and flame-retardant compound, in particular to a silicon rubber cable material ceramicized through combustion. The formula for the ceramicized silicon rubber cable material is characterized by comprising the following materials in parts by weight: 80-120 parts of silicon rubber, 20-50 parts of mineral silicate, 20-50 parts of flame retardant and 40-65 parts of reinforcing filler. A hard shell can be formed on the silicon rubber cable material prepared with the formula after a combustion test, is not easy to fall off, and protects a burned cable from being damaged, therefore, normal transmission is ensured.

Description

technical field [0001] The invention relates to a fire-resistant and flame-retardant compound, in particular to a silicone rubber cable material with ceramization after burning. Background technique [0002] At present, at home and abroad, most of them use magnesium oxide mineral fire-proof insulated cables and fire-resistant cables wound with mica tape. Because the cables of this structure require special production and processing equipment, the capital investment is too large, the cost is high, and the practical application is limited to a certain extent, and the laying and installation are difficult, and the cost of raw materials is relatively high. For fire-resistant cables wrapped with mica tape, the mica tape becomes brittle after fire and is easy to fall off, which also results in poor fire-resistant effect, making it difficult to ensure safe and smooth communication and power in case of fire. [0003] For example, the Chinese patent published on September 28, 2005, ...
