CORROSION INHIBITOR FOR COPPER-BASED MATERIAL AND LUBRICATING OIL CONTAINING THE SAME

摘要

PURPOSE:To provide a corrosion inhibitor for a copper-based material and lubricating oil contg. the corrosion inhibitor. CONSTITUTION:A corrosion inhibitor made of an amine-based org. compd. is provided as an inhibitor against the ant's nest-form corrosion of a copper- based material due to a lubricant contg. an oxygen-contg. org. compd., and a lubricant contg. the corrosion inhibitor is also provided. This lubricant contains an oxygen-contg. org. compd. but can effectively prevent ant's nest-form corrosion to the copper-based material unlike lubricating oil liable to cause ant's nest-form corrosion to the copper-based material by a reaction with water.
