Abstract

Disclosed is an emulsifying metal-cutting-fluid composition comprising base oil or oily agent, mixed alcohol-amine, anionic surfactant, nonionic surfactant, antirust agent, copper alloy corrosion inhibitor, preservative and the like. The invention has a strong general usability, suitable for metal processing, particularly aluminum alloy metal processing with advantages of excellent lubricity, corrosion resistance, a low cost and being free of toxic or harmful substances such as nitrites and phenols, so as to keep the environment and operators away from harmfulness.

Description

technical field [0001] The invention relates to metal cutting lubrication technology, in particular to composition components of emulsified metal cutting fluid. Background technique [0002] Emulsified cutting fluid is a kind of water-based cutting fluid. It is widely used in the metal processing industry because of its low cost and excellent performance. The use of pure oil lubrication, the emulsion has better cooling, prevents the sintering of the tool and the workpiece, a better working environment, no oil mist, and maintains the health of the staff. However, the existing emulsified metalworking fluids have large differences in terms of lubricity, extreme pressure, cooling, corrosion resistance, and service life due to formula and other reasons. Contents of the invention [0003] The purpose of the present invention is to provide an emulsion with better comprehensive performance and improve the service life of the emulsion. [0004] Technical solution of the present i...
