  • Adhesion aging protection in corded rubber articles
    Patent number: 10737882
    Abstract: A conveyor belt including a carry cover layer, a reinforcement layer which is situated below the carry cover layer, and a pulley cover layer which is situated below the reinforcement layer, where the reinforcement layer is comprised of steel cordage and rubber matrix, and wherein the rubber matrix includes zinc oxide in an amount greater than 5 phr and a cobalt derivative in an amount of 1 phr or greater. In some cases, the rubber matrix includes zinc oxide in an amount of 11 phr or greater, or even in an amount of 16 phr or greater. In some cases, the rubber matrix includes the cobalt derivative in an amount of 2 phr or greater, or even in an amount of from 3 phr to 4 phr. In some aspects, the rubber matrix is devoid of lead oxide.
