Problems solved by technology

[0004] Most of the current wear-resistant and flame-retardant cables use metal hydroxides as flame retardants, but because metal hydroxides will react with common polyurethane materials, long-term contact will lead to a decrease in the mechanical properties of polyurethanes, so nano-scale is currently used The mesoporous material wraps the metal hydroxide to avoid the mechanical performance defects of the cable base material, but the current mesoporous material cannot be tightly wrapped with the metal hydroxide, and the foreign particles formed after the wrapping are likely to increase the risk of cable wear and shorten the cable length. service life
