A method of producing a nanoparticle by milling layered materials is provided. Also disclosed is a method of making a lubricant, the method including milling layered materials to form nanoparticles and incorporating the nanoparticles into a base to form a lubricant.
Abstract:
PROBLEM TO BE SOLVED: To provide a novel lubricant and a friction modifier containing a solid lubricant and a binding agent as needed in an aqueous medium. SOLUTION: The problem to be solved is appropriate to lubricate steel-steel interfaces (e.g., tractor-trailer couplings, rail-wheel systems and other heavy duty applications). The invention is attained by a composition containing a friction modifier having a high or very high positive coefficient of friction such that the coefficient of friction is considerably higher than that of the solid lubricant. The invention further relates to a composition containing the binding agent and the friction modifier having a high or very high positive coefficient of friction in an aqueous medium.

Abstract:
An aqueous lubricant for use in plastic working of a metallic material which comprises (A) a water soluble inorganic salt and (B) a wax, wherein the components are dissolved or dispersed in water, and wherein a solid concentration ratio (weight ratio) (B)/(A) is 0. 3 SIMILAR 1.5. and a method for producing a lubricative film, characterized in that a lubricative film is produced by applying the aqueous lubricant, preferably in a dried weight of 0.5 SIMILAR 40g/m , on the surface of a metallic material, providing no chemical conversion layer thereon, followed by drying. The aqueous lubricant preferably further comprises (C) a metal salt of a fatty acid in a solid concentration ratio (C) /(A) of 0.01 SIMILAR 0.4. The water soluble inorganic salt (A) is preferably selected from among a sulfate, a silicate, a borate, a molybdate and a tungstate. The wax is preferably a synthetic wax which is dispersed in water and has a melting point of 70 SIMILAR 150 DEG C. The metal salt of a fatty acid (C) is preferably obtained through reacting a saturated fatty acid having 12 SIMILAR 26 carbon atoms with a metal selected from among zinc, calcium, barium, aluminium, magnesium and lithium. The aqueous lubricant can be used for imparting excellent lubricity with ease to the surface of metal having no chemical conversion layer formed thereon.
Abstract:
The invention is a particulate suspending, antimicrobial concentrate composition. The concentrate may be used in any number of environments including food service and processing environments such as brewing and bottling facilities. Generally the concentrate may be entrained in a product or introduced directly into the environment of use. The concentrate generally comprises an antimicrobial cationic compound such as a quaternary ammonium compound, and a particulate suspending surfactant such as an amphoteric propionic acid salt.
Abstract:
The object of the present invention is to provide a water-base lubricating fluid or a water-base hydraulic fluid in place of an oily liquid which has been used as a lubricating oil or a hydraulic oil applied onto the operating part of a machine and a device. The lubricating fluid of the present invention comprises fluoride ion, hydrogencarbonate ion, and water-soluble alcohols or their derivatives.
Abstract:
A grease composition for high-temperature, high-speed and high-load bearings comprises (i) a lubricating base oil composed of an alkyldiphenyl ether lubricant as an essential ingredient and having a kinematic viscosity of 90-160 cSt at 40 DEG C., and (ii) 22-30 wt. %, based on the grease composition, of a diurea compound as a thickener. The diurea compound is represented by the following formula:bon group having 6-15 carbon atoms, R1 and R3 denote an aromatic hydrocarbon group having 6-12 carbon atoms or a linear alkyl group having 8-20 carbon atoms, and the proportion of aromatic hydrocarbon groups in R1 and R3 is 70-95 mole %. The NLGI thickness grade of said composition is in a range of from No. 1 to No. 3.
