Abstract：The best formula of material was determined by studying the effect of LDPE-EVA base material, flame retardant, coupling agent, antioxidant and solvent on the properties of flame retardant materials without halogen for mine cables, including 100 phr LDPE, 22 phr EVA, 2. 8 phr antioxidants, 38 phr aluminum hydroxid, 12 phr HK560 and 7 phr MC 428. The comprehensive properties of the material prepared by the best formula were tested and compared with similar foreign products. The results show that the properties of flame retardant materials without halogen used for mine cables meet the national standard and can replace similar foreign products completely.
