Alkyl ether amine conveyor lubricants containing corrosion inhibitors

An aqueous lubricant comprising a major portion of an aqueous diluent, from about 10 ppm to 10000 ppm of at least one amine compound, having a formula selected from the group consisting of

• R.sub.1 --O--R.sub.2 --NH.sub.2,
• R.sub.1 --O--R.sub.2 --NH--R.sub.3 --NH.sub.2,
• and mixtures thereof wherein R.sub.1 is a linear saturated or unsaturated C.sub.6 -C.sub.18 alkyl, R.sub.2 is a linear or branched C.sub.1 -C.sub.8 alkylene, and R.sub.3 is a linear or branched C.sub.1 -C.sub.8 alkylene;
• an anticorrosive effective amount of a corrosion inhibitor, said corrosion inhibitor comprising a dicarboxylic acid, a tricarboxylic acid or mixture thereof;
• a detersive amount of surfactant effective to provide detergency upon use, wherein said surfactant is selected from the group consisting of an anionic surfactant, a nonionic surfactant, a cationic surfactant, an amphoteric surfactant, and mixtures thereof, wherein said lubricant has a pH of from about 7 to 10.

A method of lubricating a conveyor system using a diluted lubricant concentrate composition comprising an effective lubricating amount of one or more amine compounds, each of said amine compounds having a formula selected from the group consisting of,

• R.sub.1 --O--R.sub.2 --NH.sub.2, (1)
• R.sub.1 --O--R.sub.2 --NH--R.sub.3 --NH.sub.2, (2)
• and mixtures thereof wherein R.sub.1 is a linear saturated or unsaturated C.sub.6 -C.sub.18 alkyl, R.sub.2 is a linear or branched C.sub.1 -C.sub.8 alkylene, and R.sub.3 is a linear or branched C.sub.1 -C.sub.8 alkylene;
• an anticorrosive effective amount of a corrosion inhibitor, said corrosion inhibitor comprising a dicarboxylic acid, a tricarboxylic acid or mixture thereof;
• a detersive amount of surfactant effective to provide detergency upon dilution and use said surfactant selected from the group consisting of an anionic surfactant, a cationic surfactant, a nonionic surfactant, an amphoteric surfactant, and mixtures thereof;
• and wherein the said composition has a pH of from about 7 to 10, said method comprising the steps of:
• a. formulating the lubricant concentrate composition to have from about 0.1 wt-% to 90 wt-% of said amine compound;
• b. diluting said lubricant concentrate composition with a major portion of an aqueous diluent to form a diluted lubricant concentrate composition;
• and
• c. applying said diluted lubricant concentrate composition to the intended surface of use.
