摘要： A polyol ester-based lubricant comprising a polyol ester (A) and a polyol ester (B); the polyol ester (A) comprising an ester of a neopentyl polyol and an acid residue having a carbon number of 6-17, in which the alpha-carbon in the acid residue of the polyol ester is tertiarily branched, and when alkyl groups having 4 or more carbon atoms are bonded to the alpha-carbon, the alkyl groups are branched, and the polyol ester (B) comprising an ester of a neopentyl polyol and an acid residue having a carbon number of 6-17, in which the alpha-carbon in the acid residue of the polyol ester is secondarily or tertiarily branched and alkyl groups bonded to the alpha-carbon are straight is provided. This polyol ester-based lubricant has high performance, as demonstrated by high compatibility with substitute fluorocarbons in a kinematic viscosity range of 28 to 40 cst at 40 DEG C, excellent hydrolysis resistance, and a low pour point.
