Vulcanization accelerator, can be referred to as accelerator, in rubber vulcanization to speed up the vulcanization speed, shorten the vulcanization time, reduce the vulcanization temperature, reduce the amount of vulcanization agent, but also can improve the physical and mechanical properties of vulcanization rubber. The active agent can give full play to the effect of the accelerator, so as to activate the vulcanization reaction. At the same time, the crosslinking degree and heat resistance of vulcanized rubber can be improved. In general, accelerators and active agents are essential in vulcanization systems. Although these auxiliaries do not belong to the category of crosslinking agents, they are inseparable from crosslinking agents.
Zinc oxide is mainly used as the activator of natural rubber and synthetic rubber, the particles are small and spherical, with a large surface area, good dispersion and good adsorption, so it can promote rubber vulcanization, activation and reinforcement anti-aging effect, can strengthen the vulcanization process, achieve stable physical property, improve processing safety, and reduce the defect rate. Improve tear resistance and wear resistance of rubber products.
