Abstract:
A fire-resistant grease comprises a fire-resistant base oil and graphitic carbon or oleophilic graphite as a thickener. Suitable base oils include fire-resistant hydraulic fluids, particularly phosphorus acid esters or amides and more particularly trihydrocarbyl phosphates. The graphitic carbon may be of the type described in U.K. Pat. No. 1,252,582 (U.S. Pat. No. 3,532,625) and the oleophilic graphite as described in U.K. Pat. No. 1,168,784 (U.S. Pat. No. 3,384,583). The thickener contact may be 1-20% wt of the grease, preferably 2-10% wt, and the grease may contain conventional additives.
Abstract:
This invention concerns dual-purpose packing compositions compatible with synthetic and natural lubricating oils comprising from about 30 to 50 parts by weight of a microcrystalline wax having a melting point about 50*-75* C. admixed with about 70 to 50 parts by weight of an aliphatic ester component derived from the esterification of aliphatic alcohols, diols and polyols or their ethers by aliphatic mono- or dicarboxylic acids. The packing compositions can contain from about 0.5 to 5 parts by weight of one or more extreme pressure or load bearing additives.
Abstract:
A lubricant composition for drawing metal wire comprises a lubricant which may be particulate, liquid or semi-liquid and discrete microcapsules having a liquid core, which enhances the wire drawing agent; in particular the liquid core may be an extreme pressure additive or an anti-wear additive; the liquid is released by rupture of the microcapsules in the die so that the liquid is released at the site where it is required.
Abstract:
A turbine lubricant having outstanding oxidation stability, corrosion resistance and good viscosity stability is based on a liquid mixed isopropylphenyl/phenyl phosphate ester and contains small amounts of an amine selected from the group consisting of phenyl-.alpha.-napthyl-amine, phenyl-.beta.-naphthylamine, and diphenylamine; benzotriazole, and a corrosion inhibitor selected from the group consisting of oleylsarcosine, epoxidized soybean oil, and a mixed mono- and dialkyl phosphate of the formula RH.sub.2 PO.sub.4 and R.sub.2 HPO.sub.4, wherein R is an alkyl group of 8-12 carbon atoms.
Abstract:
A LUBRICANT IN SOLID FORM AT ROOM TEMPERATURE COMPRISING 1-HEXADECANOL (CETYL ALCOHOL) TRICRESYL PHOSPHATE IS DISCLOSED. THE LUBRICANT IS ORDINARILY USED IN CAST STICK, CAKE OR TUBE FORM AND IS EITHER APPLIED TO A SURFACE BY RUBBING THE END OF THE STICK ON THE SURFACE TO BE LUBRICATED OR THE TOOL IS COATED BY INSERTING IT IN THE LUBRICANT. THIS LUBRICANT HAS BEEN FOUND TO BE HIGHLY EFFECTIVE FOR USE WITH METAL WORKING DRILLS, SAWS, ECT. THE LUBRICANT IS NOT BRITTLE AND ADHERES TO SURFACES WITHOUT POWDERING. IT ALSO EXHIBITS IMPROVED LUBRICITY.
Abstract:
Solid stick cookware lubricant consisting essentially of lecithin and an ablative base of normally solid fatty alcohol esters such as hard fats and waxes and normally liquid comestible oils, in proportions to deposit a lubricating effective layer of lecithin onto the surface of cookware with hand pressure.
Abstract:
Method of preparing highly basic, metal containing grease and rust inhibiting compositions which is carried out by (1) forming an admixture of an oil-soluble dispersing agent, an alcohol, water, and an alkaline earth metal oxide, hydroxide or lower alkoxide; (2) carbonating the admixture to form the alkaline earth metal carbonate; and (3) heating the mixture in a controlled manner to effect a modification reaction in which the grease or rust inhibiting composition is formed as evidenced by a rapid change in the viscosity of the mixture. In an alternative embodiment of the method the water is added after the carbonation step and prior to the heating step.
