Abstract
The invention concerns a fully formulated lubricating fluid or grease comprising an additive package and a major amount of base oil, the improvement comprising the substantial absence of low molecular weight primary, secondary, tertiary, cyclic aliphatic mono or polyamines of 30 carbons or less and the absence of the corresponding acid phosphate amine salts in said fully formulated lubricating fluid.
Claims28
In a fully formulated lubricating fluid or grease including an effective amount of an acid phosphate-containing antiwear additive, characterized as comprising an additive package and a major amount of at least one base oil, the improvement comprising the absence of low molecular weight primary, secondary, tertiary, and cyclic aliphatic amines of 30 carbons or less and the absence of the corresponding acid phosphate amine salts.
A fully formulated lubricating fluid or grease suitable for use in driveline fluids and/or gear boxes for industrial applications comprising an additive package and a major amount of at least one base oil and essentially free of low molecular weight primary, secondary, tertiary, and cyclic aliphatic amines of 30 carbons or less and their corresponding acid phosphate salts.
A method for lubricating an apparatus, the method comprising applying a lubricant to the apparatus wherein said lubricant comprises a base oil, an effective amount of an acid phosphate-containing antiwear additive, said lubricant further characterized as essentially free of primary, secondary, tertiary and cyclic hydrocarbyl amines with a carbon number of C30 or less and the corresponding salts of said acid phosphate.
