Improvements in the preparation of concentrates for high water based hydraulic fluids

A high water based hydraulic fluid having about 95% water and a concentrate comprising a zincdihydrocarbyldithiophosphate, the reaction product of an alkanolamine, preferably triethanolamine, and a phosphate ester acid of the general formula: where R4 is hydrocarbyl, R5 is alkyl, each n is independe...

Beschreibung
Zusammenfassung:A high water based hydraulic fluid having about 95% water and a concentrate comprising a zincdihydrocarbyldithiophosphate, the reaction product of an alkanolamine, preferably triethanolamine, and a phosphate ester acid of the general formula: where R4 is hydrocarbyl, R5 is alkyl, each n is independently 1 or 2 and x is between 1 and 20, and optionally a polyalkylene glycol of molecular weight between 1000 and 100000. A method of preparing a concentrate is also disclosed.
