| 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；trially l isocy anate 3.0；DOP/di-nbutyl phthalate 15.0；other ingredients 29.0，total 250.0.The both compounds possess good processibility，the phy sical 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. |
