The present invention relates to an antifreeze coolant composition, and particularly to an antifreeze coolant composition comprising mercaptobenzothiazole as a heat-oxidation resistant agent, alkylbenzoate as a heat-oxidation resistant enhancer and dinonylnaphthalene sulfate as an anti-settling agent.
Description
field of invention [0001] The present invention relates to an antifreeze coolant composition having excellent anti-thermal oxidation properties, which comprises mercaptobenzothiazole as an anti-thermal oxidant, alkyl benzoate as an anti-thermal oxidation enhancer and anti-settling agent Dinonyl naphthalenesulfonate. The antifreeze coolant composition of the present invention substantially suppresses the generation of metal salt deposits, and at the same time has excellent thermal oxidation resistance at high temperatures. Background technique [0002] Generally, antifreeze coolants include antifreeze agents, anticorrosion agents, scale inhibitors, defoamers, and dyes. Examples of antifreeze agents include ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, dipropylene glycol, tripropylene glycol, and the like. Examples of corrosion inhibitors are carboxylic acid, phosphoric acid or phosphate salt, silicate, nitric acid or nitrate salt, amine, boric ac...
