Abstract

The invention provides high-flame-resistance filler comprising superfine talcum powder, light calcium carbonate, acrylate rubber, dioctyl sebacate, adhesive, barium stearate, nanoscale calcium oxide and silicon dioxide. The invention further provides a mining high-flame-resistance flexible cable comprising a cable core formed by a plurality of insulating wire cores, wherein the cable core is wrapped with an outer sheath layer; the insulating wire cores are coated with cured fire retardant coatings layers; a high-flame resistance filler layer is filled between the insulating wire cores and the outer sheath layer. By means of the high-flame-resistance filler and the mining high-flame-resistance flexible cable made from the high-flame-resistance filler, provided by the invention, the defects of poor flame resistance and poor self-extinguishing performance of existing flexible cables can be solved; the provided flexible cable has the advantages of excellent physical performance, mechanical performance, temperature resistance and flame resistance and good self-extinguishing performance.

Description

technical field [0001] The invention relates to the field of a high flame-retardant filling material, in particular to a high flame-retardant filling material and a preparation method, and a highly flame-resistant flexible cable for mining made from the high flame-retardant filling material. Background technique [0002] At present, due to people's need for safe transmission of electric energy, data, and information in mine tunnels, the safety dependence on mining mechanical equipment, communication, and lighting equipment has increased significantly. The emergence of new technologies has made it possible to connect and network equipment in this area, leading to the rapid development of ground and underground power and communication systems. In order to connect these devices, a large number of mining cables are required in these structures and fields. Typically, it is a convenient application to install mine high flame retardant flexible cables in underground ventilation sy...
