CN101638396A - Production process for rubber accelerator 2
The process comprises the following steps: adding carbon disulfide and sulfur into a reaction kettle; stirring the mixture for 2 to 4 hours under the condition that the temperature is between 25 and 30 DEG C and the rotating speed is 20 to 60 revolutions per minute; adding aniline into the mixture, wherein the mol ratio of the aniline to the

Vulcanization of rubber by sulfur alone is an extremely slow process and can take several hours at elevated temperature (140°C or more). This is problematic becasue long exposure to temperature and oxygen leads to oxidative degradation which, in turn, results in poor mechanical properties. It is also not very economical.

In rubber, an accelerator to sulfur ratio typically of 1:5 is called a conventional vulcanizing system. It gives a crosslinked network. The same principles apply to synthetic rubbers, although the optimum accelerator to sulfur ratio may not be the same as in natural rubber.
CN1781917A - Synthetic process for rubber vulcanization
The present invention is synthesis process of rubber vulcanization accelerator N-tertiary butyl bi (2-benzothiazole) sulfenimide. The process prepares the rubber vulcanization accelerator through the reaction of acid and NS in dry organic solvent in selected material ratio, temperature, reaction time and operation process.

4.12 Manufacture of Rubber Products. 4.12.1 General Process Description1. Many of the rubber manufacturing facilities in the United States produce pneumatic tires for automobile, trucks, airplanes and farm machinery. However, many rubber manufacturing facilities produce other engineered rubber products.
Allergy to rubber accelerators | DermNet NZ
Rubber accelerators are chemicals used to speed up the manufacturing process of rubber (vulcanisation). This process makes untreated natural rubber latex suitable for use in the manufacture of many rubber products. There are many types of rubber accelerators in use but those listed below cause most cases of rubber contact dermatitis:
Two roll rubber mill
This process create rubber that can be used to create products. Ingredients added to make a rubber compound include oils, fillers and accelerator, which usually includes sulfur or peroxide, and may also include a metal oxide either as activator such as zinc oxide, in some cases as filler and also as activator. After mixing, a compound is
Accelerator | rubber manufacturing
Accelerator, in the rubber industry, any of numerous chemical substances that cause vulcanization (q.v.) of rubber to occur more rapidly or at lower temperatures.Many classes of compounds act as accelerators, the most important being organic materials containing sulfur and nitrogen, especially derivatives of benzothiazole.
