LUBRICATING GREASE COMPOSITION FOR RECIPROCATING SLIDING, AND MANUFACTURING METHOD THEREFOR

摘要

Provided is a lubricating grease composition for reciprocating sliding. Said grease composition comprises a mixture of two types of grease: a grease that has a dropping point of at least 250°C and contains, in a non-fluorine base oil, either an aliphatic dicarboxylic acid and a monoamide monocarboxylic acid or a composite metal soap thickener with an aliphatic monocarboxylic acid; and a grease that contains a fluorine resin powder in a fluorine base oil that is not compatible with the non-fluorine base oil. The provided lubricating grease composition, which contains a thickener and a fluorine resin in a base oil mixture comprising a non-fluorine base oil and a fluorine base oil, has the properties necessary for a lubricating grease composition for reciprocating sliding.
