Problems solved by technology

Magnesia mineral fire-resistant insulated cables require special production and processing equipment, and the equipment for producing magnesium oxide mineral fire-resistant insulated cables needs to be imported. In addition, the outer sheath of magnesium oxide mineral fire-resistant insulated cables is all copper, and the cost is high. In practical applications It is also restricted to a certain extent, it is difficult to popularize and use it on a large scale, and it is especially difficult to promote it in civil buildings.
The fire-resistant cable wrapped with mica tape needs to be wound in multiple layers in the production process. Due to the limitation of process conditions, it is easy to cause defects at the lap joints. It is difficult to ensure the safety and smoothness of communication and power in case of fire

The invention provides novel nanometer high-temperature resistant ceramic silica gel which has good physical and chemical performance, thermal stability, flame retardancy, barrier property, optical performance, electrical properties, high and low temperature resistance, good insulation performance, high breakdown voltage, high heat-resistance index, strong bending properties, good flexibility, strong anti-jamming performance, and is nontoxic and environment-friendly.

Description

technical field [0001] The invention relates to a nano-scale high-temperature resistant ceramic silica gel formed by adding nano-scale materials into silicone rubber. Background technique [0002] In recent years, especially after the 911 incident in the United States, and after the fires in several large public entertainment venues, chemical industry, coal mines, and commercial buildings in China caused tragic loss of people's lives and property, people have a deeper understanding of fire protection and fire safety. How to ensure the smooth flow of power and communication within a certain period of time in case of fire, maximize the precious rescue time, and reduce casualties and loss of life and property, this is the subject that the industry has been constantly exploring. For cables, at present, most of the fire-resistant cables at home and abroad are magnesium oxide mineral fire-resistant insulated cables and fire-resistant cables wound with mica tape. Magnesia mineral ...
