ABRASION PREVENTING AGENT COMPOSITION, AND LUBRICANT COMPOSITION CONTAINING THE ABRASION PREVENTING AGENT COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide an abrasion preventing agent composition in which the solubility at low temperature is enhanced when it is dissolved in a mineral oil, and an oil composition with sufficient stability excellent in abrasion prevention performance in which the insoluble part is not precipitated even after dissolved.

SOLUTION: The abrasion preventing agent composition includes component (A): a hindered ester or an aromatic ester, component (B): a compound represented by formula (1) (wherein R1-R8each independently represents a hydrogen atom or a 1-20C alkyl group; X represents a 2-20C hydrocarbon group; and n represents an integer of 1-10), and component (C): a specific mono-type succinimide compound or a bis-type succinimide compound, as indispensable components. The lubricant composition is obtained by adding it.
