Abstract:
Substantially oil-free aqueous industrial fluids comprise (A) up to as much as 99.9 percent by weight water, (B) at least one substantially water-insoluble functional additive stably dispersed in the water and (C) at least one substantially water-soluble liquid organic dispersing agent, said dispersing agent being capable of dispersing said functional additive in said fluid and are useful as liquids in a variety of industrial applications, such as hydraulic systems and metal shaping operations. Typically, these compositions also contain at least one water-soluble polymeric thickener and at least one corrosion inhibitor. Methods for preparing these fluids from concentrates are also disclosed.
Abstract:
A metal working water-soluble lubricant composition comprising a water-soluble polymer compound whose counter anion is acidic phosphorus-containing compound or boric acid is disclosed.The water-soluble polymer compound is selected from the group consisting of cationic or amphoteric addition polymers, ring-opened polymers, polycondensation products and salts or quaternary ammonium salts of natural polymer derivatives having at least one basic or cationic nitrogen atom in one molecule thereof with a molecular weight of 1,000 to 10,000,000.The composition has a load resistance equal to or higher than known liquid lubricants which contain mineral oils, beef tallow etc., and shows an excellent lubricating performance when applied to a metal working surface.
Abstract:
Aqueous-base compositions are disclosed for the lubrication of the piston and the cylinder liner of Diesel engines, particularly large engines, said compositions essentially comprising one or more water soluble anti-acid neutralizers, a water soluble organic fluid having a high boiling point temperature and one or more water-soluble detergents.Tests on large engines have shown that it is possible to lubricate the piston and the cylinder liner with an aqueous base fluid without using any crude petroleum derivative.
Abstract:
A lubricating oil composition containing a synergistic corrosion inhibiting combination of 2,5-bis-hydrocarbyldithio-1,3,4-thiadiazole and a primary alkyl or alkenyl amine salt of 2-mercaptobenzothiazole.
Abstract:
A lubricating coating is applied to a metallic surface by treating the surface with an acidic aqueous coating composition comprising a coating-forming lubricant and an oxidizing agent.
Abstract:
Acidic aqueous coating compositions containing an organic coating-forming material form coatings on metallic surfaces which are immersed therein. The coating composition tends to become unstable as a result of the buildup of metallic ions in the composition. The coating composition is stabilized by removing the metallic ions from the composition or rendering them ineffective for causing the composition to become unstable.
Abstract:
GREASES THICKENED WITH CONVENTIONAL GREASE THICKENERS AND CONTAINING A CLOUDY-TYPE OVERBASED ALKALI METAL OR ALKALINE EARTH METAL SULFONATE OR CARBOXYLATE DISPERSANT AND A WATER-SOLUBLE CORROSION INHIBITING SALT. CORROSION INHIBITING CONCENTRATES ARE ALSO SET FORTH WHICH COMPRISES LUBRICATING OIL, CLOUDY-TYPE OVER-BASED DISPERSANTS, AND WATER-SOLUBLE CORROSION INHIBITING SALTS.
Abstract:
THE REACTION PRODUCT OF HEXAFLUROOISOPROPANOL WITH MONOCYCLOHEXYLAMINE OR DICYCLOHEXYLAMINE, OR MIXTURES OF BOTH, HAVE BEEN PRODUCED. THESE REACTION PRODUCTS HAVE BOTH FOUND TO BE UNUSUALLY EFFECTIVE AS CORROSION INHIBITORS. THE REACTION PRODUCTS CAN BE USED ALONE OR CARRIED IN OR ON THE SURFACE OF PAPER, PLASTICS OR OTHER SOLID MATERIALS; THEY CAN BE ADDED TO HYDROCARBONS, OILS, GREASES, HYDRAULIC FLUIDS AND OTHER LIQUID CARRIERS, EITHER IN SOLUTION OR IN SUSPENSION, AND THEY PREVENT RUSTING OF FERROUS METALS OR CORROSION OF OTHER METALS.
Abstract:
An oil-external micellar dispersion exhibiting good fireresistant properties and viscosity properties is obtained by the composition: (a) from about 71.5 to about 90 percent aqueous medium; (b) up to about 30 percent hydrocarbon; (c) at least about 4 percent of surfactant sufficient to impart micellar characteristics to ''''a'''' and ''''b'''' and, (d) from about 0.001 to about 20 percent cosurfactant. Extreme pressure agents, antifoam agents, corrosion and oxidation inhibitors, bactericides, scale inhibitors, added alkalinity, etc. can be incorporated within the composition.
