Production method
1. Prepared with n-butylamine and sulfuryl chloride as raw materials.
2.Butyl dithiocarbamate butyl ammonium salt heated to 96 ~ 100℃ decomposition, release hydrogen sulfide gas, dibutylthiourea. After separation, washing with 70 ~ 80℃ hot water, cooling crystallization, grinding, drying at 30 ~ 40℃, the finished product is obtained.
3. Using n-butylamine and carbon disulfide as raw materials, reaction at 30 ° C, and then heating at 100 ° C, decomposition.
Use
Vulcanization accelerator of natural rubber, butyl rubber, styrene butadiene rubber and neoprene rubber, especially the neoprene rubber can promote its rapid vulcanization at low temperature; Also used as natural rubber, neoprene rubber, nitrile rubber, styrene butadiene rubber anti-ozone agent. The products using this product have good physical properties, no pollution, no discoloration, Jiong and wire, industrial products and sponge products.
