DibutylCarbamodithioic acid sodium salt, white to pale yellow crystalline powder. Soluble in water and ethanol, slightly soluble in benzene and chloroform. Hygroscopic. Used as accelerator for natural rubber, styrene-butadiene rubber, nitrile rubber, and neoprene. When used in combination with diethylammonium diChemicalbook ethyl dithiocarbamate, it can be vulcanized at room temperature. By the condensation of diethylamine and carbon disulfide from the system. The aqueous solution is alkaline and gradually decomposes. In case of acid, it can separate carbon disulfide and make the solution turbid. It is a specific reagent for the determination of copper ions. DibutylCarbamodithioic acid sodium salt, also known as rubber accelerator TP, accelerator TP, is orange-yellow to orange-red viscous transparent liquid at room temperature. The molecular weight is 227, the relative density is 1.075-1.14, the content is more than 40%, the free alkali (NaOH) is less than 1.3%, and the oily substance is less than 1%. It is miscible with water and alcohol, and insoluble in hydrocarbon and chlorinated hydrocarbon solvents. This product is non-toxic and cannot be stored in iron containers. The accelerator TP is a super accelerator for natural rubber, styrene-butadiene rubber, neoprene rubber and its latex. Mainly used in latex products, thin-walled impregnated products, medical supplies, balloons, self-sulfurizing mortar and tape. Its vulcanization rate is slower than that of dithiocarbamate ammonia salt, and the scorch time is longer. In order to improve the vulcanization speed of latex materials, Chemicalbook is often used together with water-insoluble accelerator zinc dithiocarbamate or TMTM, TMTD, and the obtained products have high strength and good aging resistance. When using this product, it needs to be activated with zinc oxide, but it is not necessary to add fatty acid. If the vulcanization rate is too high, it can be inhibited by anti-aging agent MB or anti-scorch agent. This product has activation effect on thiazole accelerators. The general dosage in the latex material is 0.5 to 2 parts, and the used sulfur is 2 to 1 parts. Foreign sodium diethyl dithiocarbamate production plants mainly include DuPont in the United States, Anchor and Rohinson in the United Kingdom, Prchim in France, Ouchi Xinxing and Sumitomo Chemical in Japan, and Bozzetto in Italy.
