Title:
BIODEGRADABLE LUBRICANT COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2010/131739
Kind Code:
A1
Abstract:
Disclosed is a biodegradable lubricant composition which is obtained by blending (A) an ester that is represented by formula (1) and has a kinematic viscosity at 40˚C of not less than 300 mm2/s but not more than 1,000 mm2/s and an acid value of not more than 0.5 mgKOH/g, (B) an ester that is obtained by reacting a linear saturated aliphatic carboxylic acid and a polyhydric alcohol, and has an acid value of not more than 0.5 mgKOH/g, and (C) a phosphate ester amine salt that is obtained by reacting an acidic phosphate ester and an alkyl amine.
(In the formula, Ra represents a hydrocarbyl group having 4-20 carbon atoms, Rb represents a hydrocarbyl group having 4-18 carbon atoms, Rc represents a hydrogen atom or an acyl group having 1-10 carbon atoms, and n represents a number of 3-15.)
