Definitions
- This invention relates to lubricating greases containing certain triazoles as metal deactivators. More specifically, this invention relates to a lubricating grease comprising a lubricating oil, a thickener, and a minor proportion of a 1,2,4-triazole.
- the 1,2,4-triazoles which are useful in this invention are preferably 3-amino-l,2,4-triazoles having the formula N I-
- N-N Ti i ii-NHCORi wherein R is a member selected from the group consisting of alkyl and aryl.
- Preferable triazoles are those in which R R and R are hydrogen atoms.
- R R and R are hydrogen atoms.
- the desired number of carbon atoms in the R groups is less than 30 and preferably less than 7.
- the 3-aminol,2,4-triazoles of this invention can be used in any desired proportion. Generally proportions of about 0.00l2% by weight are used and concentrations of from about 0.1 to 0.5% by weight based on the total composition are preferred.
- the base oils of the grease can be either synthetic lubricating oils or mineral lubricating oils. Synthetic oils such as diesters, complex esters, polysiloxanes, and polyphenylethers may be used. It is, however, preferred to use a mineral lubricating oil.
- the thickener can be either organic or inorganic thickeners.
- organic thickeners are the soaps, such as the alkali and alkaline earth metal salts of fatty acids, e.g., lithium hydroxystearate. It is preferred, however, to use an inorganic thickener and more preferably an oleophilic clay, i.e., a clay that has been rendered Waterproof by the addition of a surfactant thereto.
- Suitable clays have a substantial base exchange capacity of normally at least 25 milliequivalents (meq.) per grams, preferably between 25 and 100 meq. per 100 grams.
- Particularly useful are the montmorillonite clays, and in particular those referred to as bentonites.
- the magnesium bentonites sometimes referred to as hectorites are particularly useful.
- the clay can be made oleophilic by absorption thereon or reaction thereon with organic ammonia bases or their salts.
- the clay is made oleophilic by coating with a cationic surface-active agent.
- Preferred surfaceactive agents or waterproofants are amino amides formed between aliphatic saturated or unsaturated monocarboxylic acids having 10 to 22 carbon atoms and alkylene polyamines.
- the alkylene polyamines are usually the bottoms products remaining from the manufacture of ethylene diamine, i.e., diethylene triamine and tetraethylene pentamine.
- waterproofants may be used in the proportion of 35125% w. based on the clay, and the clay may be present in the grease in the proportion of about 2.5 to 10% w. based on the total grease compositions.
- additives may be present in the grease, such as anti-wear agents, e.g., sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium metabisulfite, sodium

- antioxidants e.g., aromatic amines and anti-corrosion agents, e.g., alkaline metal nitrites and extreme pressure agents, e.g., lead naphthenates or metal sulfides.
- the clay product is mixed with a lubricating oil in order
- the greases may be prepared by either a wet or to prepare the grease.
- the mixture is sheared powdered process. at normal or elevated temperatures, e.g., 80 C., and
