Abstract

The invention relates to the field of halogen-free low-smoke flame-retardant cables and provides a high-efficiency fireproof flame-retardant cable for improving the flame retardant effect of cables. The provided high-efficiency fireproof flame-retardant cable comprises core wires, a cable forming layer and a sheath layer, wherein the core wires are connected with the cable forming layer, and the cable forming layer is connected with the sheath layer; each core wire comprises a conductor and an insulating layer, and the insulating layers are connected with the cable layer; the cable forming layer comprises a non-woven fabric layer and a polypropylene layer, a non-woven fabric is coated with the core wires after twisting, and the non-woven fabric layer is formed on the twisted core wires and then coated with a polypropylene material to form the polypropylene layer. By adding a modified flame retardant in the production process of the polypropylene material, the fireproof flame-retardant effect of the cable can be effectively improved, and correspondingly the needs of various application scenes can be met in practical application.

Description

technical field [0001] The invention relates to the field of halogen-free low-smoke flame-retardant cables, in particular to a high-efficiency fire-proof and flame-retardant cable. Background technique [0002] Promoting the use of flame-retardant cables is of great significance to fire prevention. Although the existing cables comply with the provisions of GB19666 and IEC60332-3, in practical applications, even if the products that pass the above two standards are tested, they cannot meet the actual needs of fire safety in construction projects in my country, especially in different occasions. need. [0003] For this reason, in order to meet the actual needs of fire safety in my country's construction projects, the country promulgated GB31247-2014 in 2014, aiming to further standardize the production inspection of such cables. Furthermore, how to produce flame-retardant products that meet the new standards, especially how to improve the flame-retardant effect of cables whil...
