Rubber vulcanising accelerator is a substance that promotes vulcanization. It can shorten the vulcanization time, reduce the vulcanization temperature, reduce the amount of vulcanizing agent and improve the physical and mechanical properties of the rubber. It can be divided into two categories: inorganic accelerators and organic accelerators. Among the inorganic accelerators, except for a small amount of magnesium oxide and lead oxide, the rest are mainly used as auxiliary accelerators.

  The vulcanization process of rubber is often slow in reaction. In order to accelerate the reaction between rubber and vulcanizing agent, when rubber is processed, it can be mixed into the rubber compound, which can reduce the vulcanization temperature, shorten the vulcanization time, reduce the amount of sulfur, and also improve the physical and mechanical properties of the vulcanizate. The substance is called vulcanization accelerator, referred to as accelerator. Accelerator can speed up the reaction between rubber and vulcanizing agent, increase vulcanization speed, reduce vulcanization temperature, shorten vulcanization time, reduce the amount of vulcanizing agent, and improve the physical and chemical properties and appearance of vulcanized rubber. Therefore, accelerators play a very important role in the rubber vulcanization process.
