Title: METHOD FOR PRODUCING LUBRICANT COMPOSITION, AND LUBRICANT COMPOSITION
Abstract:
Provided is a lubricant composition which is capable of reducing friction even under harsh conditions such as high temperature and/or high pressure, and which has a good balance between wear resistance and welding resistance. A method for producing a lubricant composition according to the present invention comprises a step for mixing a composite ester A, which comprises a polyester obtained by fusing a polyhydric alcohol a1 having a functionality of 3 or more, a polyvalent carboxylic acid a2 having a valence of 2 or more, and at least one substance selected from among monohydric alcohols a3 and monovalent carboxylic acids a4, with a compound B having a hydroxyl number of more than 50 mgKOH/g. A lubricant composition according to the present invention contains the composite ester A and the compound B.
