Title:

LUBRICANT COMPOSITION AND LUBRICANT COMPOSITION PRODUCTION METHOD

Document Type and Number:

WIPO Patent Application WO/2016/017548

Kind Code:

A1

Abstract:

The purpose of the present invention is to provide a lubricant composition which reduces both friction and wear at various temperatures and loads, and to provide a production method of the lubricant composition. This lubricant composition contains a composite ester A which includes polyesters formed by condensation of at least: a polyol a1 having a valance of 3 or higher; a mixture b1 which contains at least 75 mass% divalent carboxylic acid of 36-44 carbon atoms and which is a polymer reactant mixture of non-saturated fatty acids of 18-22 carbon atoms, and/or a mixture obtained by hydrogenating the polymer reactant mixture; and a mono-al c1 represented by general expression (1). The ratio of the molar number of hydroxyl groups in a1 / the molar number of carboxylic acid in b1 / the molar number of hydroxyl groups in c1 is 1/1.5-2.0/0.7-1.5, and the content of the complex esters A in the lubricant composition is 0.1-5 wt% with respect to the total mass. General formula (1): R-OH
