At present, in the rubber industry Mid-Autumn lamb class and sulfur-containing morpholine derivatives are still the main sulfide.The vulcanization of thiuram products is characterized by good vulcanization flatness and small scorch tendency.This is because sulfurants (such as DTDM) synthesized by secondary amine precursors can produce nitrosamines.In 1937, the British scholar FREUND first reported two cases of poisoning from exposure to dimethylnitrosamine (NDMA).After the study found that nitrosamines are a strong carcinogen, can cause a variety of organs and tissues of cancer.Later, it was found that this kind of material is a direct carcinogen that does not need activation, and this kind of material is widely found in nature, and found in food, drink, tobacco, cosmetics and rubber products are nitrosamines.Nitrosamines are now known to cause cancer in animals and humans.At present, the main research focus of sulfur donor is to change the chemical structure of synthetic precursors.

DTDC is a sulfur donor and can be used as a vulcanizing agent for rubber.Vulcanization does not occur at lower temperatures, and only when the temperature rises to the vulcanization temperature can active sulfur be decomposed, and the vulcanization reaction begins.Therefore, the operation is safe, can improve the coke burning safety, and can greatly reduce the phenomenon of sulfur injection of rubber than sulfur sulfide alone.In addition, DTDC is better than the traditional curing agent another aspect is that in the vulcanization, DTDC formed a single sulfur bond and double sulfur bond crosslink more, and less sulfur bond crosslink, so the vulcanized rubber has good aging resistance.
