ANTIFREEZE COOLANT COMPOSITION FOR HIGH TEMPERATURE APPLICATIONS |
摘要 |
The present invention comprises an improved antifreeze coolant composition with certain additives that serve to increase the thermal stability of the glycol component of a glycol/water coolant composition and to reduce the tendency of the glycol component to degrade under elevated thermal condition s. These additives comprise organic compounds with a carboxylic acid moiety and a hydroxyl moiety, and also tricarballylic acid. Another aspect of this invention concerns a method for improving the stability of the glycol component of a glycol/water coolant composition in engine cooling/heating systems by formulating a glycol/water coolant composition with the thermal stability additive to form an improved coolant composition, and contacting t he engine cooling/heating system with the improved coolant composition.
