Energy-saving low-rolling-resistance conveyor belt cover rubber and production method thereof

Abstract

The application discloses energy-saving low-rolling-resistance conveyor belt cover rubber and a production method thereof. Raw materials are prepared from the following components in parts by weight: epoxy natural rubber, rare earth butadiene rubber, high styrene rubber, high structure carbon black, high dispersion silicon dioxide, silane coupling agent, softening agent, indirect method zinc oxide, stearic acid, antioxidant 4010NA, antioxidant RD and vulcanization system. The application relates to the technical field of conveyor belt materials. The energy-saving low-rolling-resistance conveyor belt cover rubber and the production method thereof are characterized in that, through the synergistic effect of the C=C double bond breakage in the rare earth butadiene rubber and the crosslinking of the epoxy groups in the epoxy natural rubber, a stable three-ring epoxy group structure is formed, under the action of sulfur crosslinking, a more stable three-dimensional net structure is formed, the bond energy is high, the elasticity is good, and the internal heat after deformation is small.
