Abstract:
A process for manufacturing a lubricant composition comprises combining a superabsorbent polymer with a material for decreasing friction between surfaces that frictionally engage one another, by polymerizing monomers of the superabsorbent polymer with the material for decreasing friction, or polymerizing the monomers for forming the superabsorbent polymer with the material for decreasing friction and a binder, where the binder is selected from thermoplastic resins or curable resins. The superabsorbent polymer 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. The material for decreasing friction comprises a petroleum lubricant, synthetic lubricant, grease, solid lubricant or metal working lubricant optionally containing a lubricant additive, or mixtures thereof. The process encompasses conducting the polymerization and coating the lubricant composition on a surface such as a wire or cable. The various processes also yield products produced by the process.
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.

Abstract:
Die release lubricant is made from powder solid lubricant, adhesion enhancer made of organic or inorganic compound and volatile solvent. Before melted metal is injected into a die for casting, the die release lubricant is sprayed to an inside surface of the die. The die release lubricant is in a liquid state and is uniformly applied to the inside surface of the die. As a result, application efficiency of the die release lubricant is improved while an amount of thermal decomposition gas generated during casting is reduced.
Abstract:

F. to retain a low coefficient of friction in an oil starved environment.
Abstract:
A lubrication block, with or without a cavity, or a lubrication bag, for lubricating an ID surface of a tire and an OD surface of a plurality of pads of rotary trunnion supported equipment, such as a kiln, cooler, dryer, reactor, granulator and ball mill operating at temperatures from 100.degree. F. to 500.degree. F. or higher. The tire has inner and outer faces, and the inner face of the tire is slipped over the plurality of pads or filler bars welded to an outer shell of the rotary equipment. The lubrication block or bag is sized so as to be inserted in between the pads. The lubrication block comprises a lubricant and a solid carrier for said lubricant. The carrier is selected from the group consisting of waxes such as paraffin, polymers, copolymers such as ethylene or polyethylene glycol or mixtures thereof, and the lubricant comprises powdered carbon and a soft metal powder (e.g. copper, zinc, aluminum) or a noble metal powder (e.g. silver, copper).
