Abstract：A semi-conductive shielding layer compound for mine cable has been developed. The formula based on NBR is as follows: NBR2707 100; conductive filler 100; zinc oxide 10.0; TMTD 4.0; DOP 23.0; other ingredients 13.0, total 250.0. The formula based on EVA is as follows: EVA Levaprene 560 100; conductive filler 100; DCP 3.0; triallyl isocyanate 3.0; DOP/di-n-butyl phthalate 15.0; other ingredients 29.0, total 250.0. The both compounds possess good processibility, the physical properties of their vulcanizates meet the requirements in the national standard GB 7594-87, and the performances of finished cable meet the requirements in the national standard GB 12972-91.
