COMPOSITION FOR ANTIFREEZE LIQUID OR COOLANT HAVING SUPERIOR CAVITATION EROSION- AND GAP CORROSION-RESISTANCE EFFECT |
摘要 |
The present invention relates to a composition for an antifreeze liquid or a coolant. The present invention provides the composition for the antifreeze liquid or the coolant comprising: (a) a glycol-based antifreeze agent; (b) a cyclo hexane dicarboxylic acid; and (c) a non-reduced polyol. Generally, a mixture of mono- or dicarboxylic acid, which is used as a corrosion inhibitor agent, and an inorganic additive is prone to cavitation erosion and corrosion of gaps, but when a composition is comprised by using in parallel the cyclo hexane dicarboxylic acid and the non-reduced polyol, a synergy effect is created, thereby exhibiting a superior corrosion prevention effect with respect to cavitation erosion and corrosion of gaps inside a cooling apparatus. |
