Rubber vulcanization is mainly carried out using sulfur, but the reaction between sulfur and rubber is very slow, so vulcanization accelerators have emerged. Adding an accelerator to the rubber material can activate the vulcanizing agent, thereby accelerating the cross-linking reaction between the vulcanizing agent and rubber molecules, achieving the effect of shortening vulcanization time and reducing vulcanization temperature.The promotion efficiency of rubber vulcanization is an important standard for measuring the quality of accelerators. From the reports, the characterization of accelerators at home and abroad mainly focuses on two aspects: the vulcanization promotion characteristics and the psical and mechanical properties of vulcanizate. The vulcanization promotion characteristics mainly examine aspects such as vulcanization rate, Mooney scorch time, positive vulcanization time, positive vulcanization temperature, vulcanization flatness during the over vulcanization stage, and resistance to vulcanization reversion.One of the commonly used aftereffect accelerators.Suitable for the use of furnace black rubber, mainly used in tires, rubber shoes, rubber hose, tape, cable, general industrial products.
