The invention discloses modified petroleum coke for rubber addition, a preparation method thereof and tire rubber, the modified petroleum coke is prepared by reaming petroleum coke and performing coupling agent surface modification, the heating loss of the modified petroleum coke is less than or equal to 3%, the iodine absorption value is 150-160g/kg, the oil absorption value is (100-110) * 10 <-5 > m < 3 >/kg, the BET specific surface area is (140-150) * 10 < 3 > m < 2 >/kg, and the CTAB adsorption specific surface area is (120-130) * 10 < 3 > m < 2 >/kg. The modified petroleum coke prepared by the invention can be used for replacing carbon black in rubber processing, so that the recycling of industrial excess materials is realized, the problem of high production cost of carbon black is solved, and meanwhile, the requirement of comprehensive performance is met.

    本发明公开了一种橡胶添加用改性石油焦及其制备方法和轮胎橡胶,所述改性石油焦由石油焦经过扩孔、偶联剂表面改性制得,所述改性石油焦的加热减量≤3%,吸碘值为150~160g/kg,吸油值为(100~110)×10‑5m3/kg,BET比表面积为(140~150)×103m2/kg,CTAB吸附比表面积为(120~130)×103m2/kg。本发明制得的改性石油焦可用于替代橡胶加工中的炭黑,以实现工业余料的再利用,以解决采用炭黑生产成本高的问题,同时又满足综合性能的要求。
