Abstract:
An aqueous lubricant for use in plastic working of a metallic material which comprises (A) a water soluble inorganic salt, (B) a lubricating agent selected from molybdenum disulfide and graphite and (C) a wax, wherein the components are dissolved or dispersed in water, and wherein a solid concentration ratio (weight ratio) (B)/(A) is 1.0 to 5.0 and (C)/(A) is 0.1 to 1.0; and a method of lubricant film processing of a metallic material, characterized in that a lubricant film is formed by applying the aqueous lubricant in a dried weight of 0.5 to 40 g/m on a clarified metal material, followed by drying. The water soluble inorganic salt(A) is preferably selected from the group consisting of a sulfate, a silicate, a borate, a molybdate and a tungstate. The wax (C) is preferably a natural wax or a synthetic wax which is dispersed in water and has a melting point of 70 to 150 DEG . The aqueous lubricant can be used for imparting excellent bubricity with ease to the surface of a metal having no chemical film formed thereon.

Abstract:
A waterborne lubricant is provided that can form coatings on metal surfaces, inexpensively and with little environmental pollution load, wherein said coatings exhibit very good sliding properties. Also, a surface treatment method that uses the novel waterborne lubricant is provided. The waterborne lubricant contains molybdenum disulfide and waterborne resin having specified characteristics.
Abstract:
Dry film lubricant coatings are provided by using a silicone resin binder, either as an aqueous emulsion or in a solvent-based system, to fix an alkaline earth metal fluoride to a substrate. The compositions used to apply the coatings may also include relatively minor amounts of xylene, ammonium benzoate, a wetting agent, and/or a porosity-inducing agent - although none of those additives remains in the cured coating. Multi-layer dry film lubricant coatings are also disclosed, with the multi-layer coating having a basecoat layer as described above, and a topcoat layer made of a layer-lattice solid such as graphite or molybdenum disulfide, and a silicone resin, aluminum phosphate or an alkali metal silicate binder.
Abstract:
The invention relates to a lubricant which can be used as a mandrel lubricant with a content of 75 to 90 wt. % of graphite and contains 1 to 10 wt. % of a phosphate. Said lubricant can also contain 1 to 4 wt % alkali silicate, 1 to 10 wt. % bentonite, 0.5 to 1 wt. % silico-phosphate and common solid lubricants. Said lubricant is preferably used as an aqueous suspension with a solid content of 20 to 40 wt. %.
Abstract:
The disclosure pertains to a novel roller lubricant consisting of polyalkylene glycol, a thickening agent, one or more clay minerals and, optionally, graphite. The novel roller lubricant can be used to lubricate rollers used to produce profiled sections or sheets.
Abstract:
According to the method of the invention, first a paste is produced from a plastics dispersion and fillers in order to form the plastics sliding layer. This paste is free from organic solvents and is applied to a sintered porous metal layer. The resultant multi-layer material is then sintered. Since organic solvents are not used, the risks to health and the risk of fire are considerably reduced. Furthermore, the composite materials produced according to the invention have exceptional resistance to cavitation. In addition to conventional fields of application relative to lubrication-free articles, such as bearings, these composite materials can therefore also be used in gear pumps and shock absorbers.
Abstract:
The present invention relates to environmentally advantageous, anti-corrosion lubricating paste compositions comprising a base and a carrier, the carrier being present in a major proportion with respect to the base. Further, in one aspect of the invention, the base comprises wax and graphite, and the carrier comprises petrolatum or mineral oil.
