Abstract
A manufacturing method of a lubricant composition includes mixing a composite ester A that contains polyester obtained by condensing trihydric or more polyhydric alcohol a1, a divalent or more polyvalent carboxylic acid a2, and at least one selected from monohydric alcohol a3 or a monovalent carboxylic acid a4, with a compound B having a hydroxyl number of greater than 50 mgKOH/g. A lubricant composition contains the composite ester A and the compound B.
Claims12
A manufacturing method of a lubricant composition, comprising:
- mixing a composite ester A that contains polyester obtained by condensing trihydric or more polyhydric alcohol a1, a divalent or more polyvalent carboxylic acid a2, and monohydric alcohol a3 having an oxyalkylene structure, with a compound B represented by any one of General Formulae 1 to 3 and having a hydroxyl number of greater than 50 mgKOH/g,
- wherein in General Formulae 1 to 3, R1 to R3 each independently represent a hydrocarbon group having 4 to 30 carbon atoms;
- Y represents an alkylene group having 2 to 4 carbon atoms, and, in a case where a plurality of Y's are present in one molecule, the plurality of Y's may be the same or different from each other;
- and m, n, and p each independently represent an integer of 0 to 20.
