Product Applications

Aftereffect accelerator. It can be used for natural rubber, cis-butyl rubber, isoprene rubber, styrene-butadiene rubber and natural rubber recycled rubber. The usage method and properties are basically similar to the accelerator CZ, but the aftereffect is slightly larger in natural rubber. The product should be equipped with zinc oxide and stearic acid, and can also be activated by autumn lamb, dithiocarbamate, aldehyde Amine, guanidine accelerator and acidic substances. Slight pollution, almost no discoloration. Among the total consumption of accelerants, M and DM are the largest in China, and CZ (2900T in 1990) is the third largest in China. NOBS has developed rapidly in recent years, it has developed from 655t production in 1985 to 1305t in 1990. These varieties are derivatives of promoter m. At present, the main problem that troubles the vulcanization accelerator industry is that nitrosamines cause cancer.

Production method

It is obtained by the reaction of the sodium salt of 2-thiobenzothiazole (promoter m) with tert-butylamine. Slowly add 0.75mol tert-butylamine to 0.5mol of 13 promoter M sodium salt solution, add 0.36mol of 25 sulfuric acid solution half an hour later, and react at 45-50 ℃ for 0.5h. Then 0.6 mol15 sodium hypochlorite was added within 2 hours. Reaction aftercooling; Throw filter; Wash, dry the product below 50 ℃.
