GREASE COMPOSITION

摘要

A grease composition for use in resin lubrication wherein at least one amine salt of an unsaturated or saturated fatty acid is incorporated in a grease base material which includes a base oil and a thickener, preferably wherein at least one fatty acid amine salt of the following general formula (1) is incorporated: RCOO- R' NH3 + wherein either (i) R is an unsaturated hydrocarbon group having from 15 to 21 carbon atoms, and R' is a saturated or unsaturated linear or branched hydrocarbon group having from 8 to 22 carbon atoms; or (ii) R is a linear saturated hydrocarbon group having from 5 to 21 carbon atoms, and R' is an unsaturated hydrocarbon group having from 16 to 18 carbon atoms. The grease composition of the- present invention improves the lubricity between resin and resin or resin.and another material such as a metal.
