PROBLEM TO BE SOLVED: To provide additives for lubricant for improving tribologic properties, to provide novel lubricants containing the additives, and to provide a process for the preparation thereof. SOLUTION: The lubricants contain nano particles, and the lubricants are characterized in that: the nano particles are ceramic particles which have preferably specified shapes and specified particle sizes and have specified thermal conductivity; the nano particles are dispersed in base material oil comprising natural oil, mineral oil and/or synthetic oil, ester oil or the like. The process for the preparation of the lubricants is also provided. COPYRIGHT: (C)2011,JPO&INPIT

Date Apr. 2, 1998The present invention relates to novel lubricant compositions comprising a solid lubricant and a binding agent in water medium suitable for lubricating steel-steel interfaces such as tractor-trailer couplings, rail-wheel systems and other heavy duty applications. The invention also relates to compositions described above which include friction modifiers with high or very high and positive coefficients of friction such that the coefficient of friction is considerably higher than the solid lubricant. The invention further relates to compositions comprising a binding agent and a friction modifier with a very high and positive coefficient of friction in a water medium.

PROBLEM TO BE SOLVED: To provide a lubricant composition, which can be used for various purposes and can reduce an electric power and fuel consumption and further increase cooling efficiency and suppress the lowering of developped output when it is used in a compressor or an internal combustion engine and the like. SOLUTION: The lubricant composition is a lubricity base oil containing the primary ultrafine powder of a metal and the secondary ultrafine powder of a mineral. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
Agent for the pickling of and as an antioxidant for workpieces made of iron and steel in the case of when they are subjected to non-cutting, hot transformation. The agent is used in dry form. The agent contains: (a) 20 to 80 percent by weight of a pickling-effective compound, such as, sodium metaborate; (b) 1 to 80 percent by weight of a component, such as, graphite; and (c) zero to 79 percent by weight of at least one substance selected from group (d), (e) and/or (f). Zero to 35 percent by weight of group (d), such as, coke, can be used as substance (c) and, for example, act as antioxidants. Zero to 50 percent by weight of group (e), such as, sodium chloride, can be used as substance (c), and control the physical characteristics. Zero to 5 percent by weight of group (f), such as, ammonium chloride, can be used as substance (c) and, for example, act on the reduction of the oxides of group (a).
Abstract:
PURPOSE:To provide the titled die lubricant which consists of phosphoric acid (salt), boric acid (salt), salt or hydroxide of alkali metal and laminar silicate in specified proportions and exhibits excellent lubricating and release properties. CONSTITUTION:A water-soluble glass (A) is prepared by mixing 14-50mol% (as P2O3) phosphoric acid (salt), 0-80mol% (as B2O3) boric acid (salt) and 30- 80mol [as M2O (M is alkali metal)] at least one compd. selected from among carbonate, nitrate, sulfate and hydroxide of alkali metal (e.g. Na2CO3) and melting the mixture followed by quenching. For applications where the lubricity is important, 91-99.5wt% (A) is mixed with 9-0.5 laminar silicate (B) (e.g. white mica) and for applications where importance is attached to the releasability 0.5-39wt% (A) is mixed with 99.5-61wt% (B).
