Brief introduction of rubber promoter
- Aug 16, 2017-
Rubber Accelerator is the rubber vulcanizing accelerator. Rubber vulcanization is mainly used for sulphur, but the reaction of sulphur and rubber is very slow, so the vulcanizing accelerator emerges. The promoter can activate the vulcanizing agent in the binder, thus speeding up the crosslinking reaction between the vulcanizing agent and the rubber molecule to shorten the vulcanization time and reduce the curing temperature. The main use of vulcanizing accelerator according to the chemical structure of the main secondary sulfonamide, thiazole, Autumn lamb, as well as some of the guanidine, thiourea and disulfide carbamate salts. One of the best synthesis of the second sulfonamide, the most widely used.
