Description

technical field [0001] The invention relates to a compound synthesis device, in particular to a production device of a vulcanization accelerator 2-mercaptobenzothiazole. Background technique [0002] 2-Mercaptobenzothiazole, as a general-purpose vulcanization accelerator, is widely used in various rubbers. It has a rapid acceleration effect on natural rubber and synthetic rubber usually vulcanized with sulfur. Zinc oxide, fatty acid, etc. activation is required before use. It is often used in combination with other accelerator systems, such as dithiothiuram and tellurium dithiocarbamate as an accelerator for butyl rubber; used in combination with tribasic lead maleate for light-colored water resistance Chlorosulfonated polyethylene compound. 2-Mercaptobenzothiazole can also be used as copper corrosion inhibitor in circulating cooling water system. Its corrosion inhibition mainly depends on a kind of chemical adsorption with active copper atoms or copper ions on the surfa...
