The invention provides a comprehensive predispersed anti-scorching accelerant and a preparation method of the comprehensive predispersed anti-scorching accelerant. An accelerant NS (N-tert-butylbenzothiazole-2-sulphenamide) and an anti-scorching agent CTP (N-cyclohexylthio phthalimide), which are used as main raw materials, are compounded and granulated, the obtained product has low Mooney viscosity and good dispersibility with rubber, and is easy to disperse in rubber uniformly, so as to improve the quality of a rubber product, expand the using range of the accelerant NS and overcome the defect that certain products cannot use the NS and use N0BS with high toxicity; and besides, the comprehensive predispersed anti-scorching accelerant has accuracy in feeding, prolongs the scorching time, shortens the vulcanizing time, and saves the energy and the like when being applied to rubber processing, and meets the concept of green chemical industry.
