Abstract
The present invention relates to a rubber composition containing a rubber component, a eutectic compound, metal oxide, and a peroxide-based crosslinking agent, and a production method thereof. The rubber composition in which the blending amount of metal oxide such as zinc oxide is largely reduced is obtained, which may have the same vulcanization characteristics and vulcanized-rubber physical properties as those of a rubber composition in which a large amount of metal oxide is blended, while considering the environment.
Claims21
A rubber composition comprising a rubber component, a eutectic compound, metal oxide, and a peroxide-based crosslinking agent.
