In addition, in the vulcanization molding process of rubber, a vulcanization activator is generally added for improving the vulcanization speed, and the vulcanization activator has the effects of activating a vulcanization system, improving the crosslinking density of vulcanized rubber, improving the ageing resistance of the vulcanized rubber and the like. In the high-temperature vulcanization process of rubber, part of vulcanization accelerator and sulfur carrier can generate secondary amine in the vulcanization process, and stable nitrosamine can be generated with nitrogen oxides in air or additives under certain conditions. Nitrosamines are difficult to remove by washing and soaking. Nitrosamines are strong carcinogens and are released during use, which severely threatens human health. Increasingly, people pay attention to physical health and environmental protection, and more countries and regions strictly limit a rubber product vulcanization system: no nitrosamines are produced during vulcanization. For example, ASTM F1313 of the American society of materials and national Standard SN/T4694-2016. Therefore, the development of a compound vulcanization activator formula system which does not generate nitrosamine, does not spray frost and has high scorching safety meets the market application and use requirements, and is a necessary way for promoting the green and high-quality development of the rubber industry.
