  • Method for producing rubber composition
    Patent number: 9145475
    Abstract: A method for producing a rubber composition containing by weight 5 to 95 parts of natural rubber (NR), 95 to 5 parts of chloroprene rubber (CR), and 20 to 90 parts of carbon black (CB), using a kneading machine, includes a first step of producing a master batch (M1) containing NR and CB; a second step of producing a master batch (M2) containing CR and CB, and a third step of mixing the M1 and M2 with each other to produce a master batch (M3) containing NR, CR, and CB, wherein the amount of CB contained in the M2 is from 40 to 70% by weight relative to the total amount of CB in the rubber composition, and when the M2 is discharged from the kneading machine after the second step, the actually measured temperature of the rubber composition is from 100 to 130° C.
