Based on the dispersion form of inorganic compounding agents in rubber, the mechanism of action of nano zinc oxide in rubber and its effect on the properties of rubber are studied. During the vulcanization process, zinc oxide as an active agent reacts with organic accelerators, stearic acid, sulfur, etc. on the surface of zinc oxide particles. Replacing ordinary indirect zinc oxide with an equal a
