Abstract:
To provide a coating composition for a lubricating coating film capable of forming a lubricating coating film having a high level of flexibility on surfaces of various base materials. A coating composition for a lubricating coating film including: (A) a phenolic resin, (B) an epoxy resin having an epoxy equivalent weight of 600 to 4000, and (C) at least one type of solid lubricant; and having a weight ratio of component (A) to the total weight of component (A) and component (B) of at least 50 weight %.
Abstract:
A novel hydraulic fluid composition for application to drilling equipment is described herein. These hydraulic fluid compositions permit effective monitoring or controlling well-head pressure of a well during drilling on land or offshore. The hydraulic fluid compositions prevent uncontrolled flow of gas, oil, or another well fluid out of an underground formation during a drilling or extraction process when applied to the drilling equipment. Accordingly, provided is a hydraulic fluid concentrate which contains a water-soluble phosphate ester and a sulfide compound containing at least one S-S linkage, at least 10 carbon atoms and at least one terminal carboxylate group, wherein the S-S linkage bridges two alkyl groups. Additional components can be added to the concentrate and include one or more alkaline compound, one or more dicarboxylic acid or salt thereof, a water-soluble corrosion inhibitor, a water-soluble biocide, a pour point depressant, and water, ethylene glycol, or a combination thereof. The concentrate is then further diluted by the customer for use as described herein. Particularly, these compositions are effective in reducing seawater corrosion of a metal in contact with the hydraulic fluid composition, reducing bioaccumulation in oil drilling equipment contacted with the hydraulic fluid composition, and have low toxicity to sea life.

Abstract:
Disclosed is a flame-retardant lubricant composition for cold working which contains no chlorine compound and exhibits good lubricity and welding resistance. Also disclosed is a cold working method using such a lubricant composition. Specifically disclosed is a lubricant composition for cold working which contains, in a lubricant base oil, at least one carbonate selected from alkali metal carbonates and alkaline earth metal carbonates, and at least one hydroxide selected from alkali metal hydroxides and alkaline earth metal hydroxides. This lubricant composition contains no chlorine compound. The carbonate content in the composition is not less than 10% by mass and less than 100% by mass, and the hydroxide content is more than 0 part by mass and not more than 5 parts by mass per 100 parts by mass of the carbonate.
Abstract:
A process is disclosed for manufacturing a lubricant composition comprising combining a superabsorbent polymer with a material for decreasing friction between moving surfaces. The superabsorbent polymer absorbs from about 25 to greater than 100 times its weight in water and may comprise a polymer of acrylic acid, an acrylic ester, acrylonitrile or acrylamide, including co-polymers thereof or starch graft co-polymers thereof or mixtures thereof. A product produced by the process includes the material for decreasing friction comprising a petroleum lubricant containing an additive, water containing an additive, synthetic lubricant, grease, solid lubricant or metal working lubricant, wherein the synthetic lubricant, grease, solid lubricant or metal working lubricant optionally contain an additive. A process comprising controlling the delivery of a lubricant to at least one of two moving surfaces in order to decrease friction between said moving surfaces, is also disclosed. This process includes applying the lubricant composition to at least one of the surfaces. The lubricant composition in this instance comprises a superabsorbent polymer combined with a material for decreasing friction between moving surfaces, wherein the material for decreasing friction comprises a petroleum lubricant, water, synthetic lubricant, grease, solid lubricant or metal working lubricant, and optionally an additive.
