Patent

CA 2408712

A lubricant composition is disclosed that comprises: (a) a lubricant and (b) at least one molybdenum-containing compound in the form of surface-capped nanosized particles of the general formula: (Z)n(X-R)m wherein Z is an inorganic moiety comprising molybdenum and sulfur in the form of particles having dimensions in the range of from about 1 to about 100 nm; (X-R) is a surface-capping reagent wherein R is a C4 to C20 straight or branched-chain alkyl or alkylated cycloalkyl radical or radicals and X is a functional group capable of specific sorption and/or chemical interaction with molybdenum/sulfur moiety; n is the number of molecules of Z in the particles; m is an integer representing the amount of surface-capping reagents relative to a single particle; and the ratio of m to n is in the range of from about 1:1 to about 10:1.

La présente invention concerne une composition lubrifiante, qui comprend A) un lubrifiant et B) au moins un composé contenant du molybdène, sous forme de nanoparticules à revêtement superficiel, de formule (Z)¿n?(X-R)¿m?, dans laquelle Z représente un groupe inorganique comprenant du molybdène et du soufre, sous forme de particules dont les dimensions vont d'environ 1 à environ 100 nm, (X-R) est un réactif de revêtement superficiel, R représentant un/des radical(s) alkyle ou cycloalkyle alkylé, C¿4? à C¿20?, à chaîne droite ou ramifiée, et X représentant un groupe fonctionnel à pouvoir de sorption et/ou d'interaction chimique spécifique avec un groupe molybdène/soufre, n représente le nombre de molécules de Z dans les particules, m est un entier représentant la quantité de réactifs de revêtement superficiel par particule et le rapport de m sur n va d'environ 1:1 à environ 10:1.
