Problems solved by technology

[0002] With the rapid development of my country's market economy, the coal industry, as one of the basic technologies of the world's major energy sources, has developed rapidly, and people have paid more attention to the safety of mines. The safety of the mine and the life of the miners are also of concern to the flame retardant performance of the supporting cables. The flame retardant cable is that when the cable itself catches fire for some reason or is ignited by an external fire source, the cable will not continue to burn after the fire is extinguished. , or the burning time is very short, the flame retardant performance of the flame retardant cables in the prior art is weak, and it is difficult to meet the requirements of high flame retardant
