Total-synthesis water-base metal cutting fluid and preparation method

Abstract

The invention discloses a total-synthesis water-base metal cutting fluid and a preparation method. The cutting fluid is composed of triethanolamine, monoethanolamine, a special amine, an antirust agent, ethylene oxide-propylene oxide block copolymer PN30, neodecanoic acid, a quaternary amine cationic surfactant chlorine salt and hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine, and the balance water. The preparation method comprises: adding triethanolamine, monoethanolamine, the special amine, the antirust agent and water into a reaction tank according to a ratio and stirring; adding ethylene oxide-propylene oxide block copolymer PN30 and neodecanoic acid according to a ratio into the mixture in the reaction tank, and stirring; and finally adding the quaternary amine cationic surfactant chlorine salt and hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine into the reaction tank and stirring, so as to obtain the cutting fluid. The cutting fluid has advantages of a total-synthesis type cutting fluid, is excellent in performances and does not contain nitrites and other compositions harmful to human body. By utilizing the method for preparing the cutting fluid, the preparation process is simple and operation is convenient.

Description

technical field

[0001] The invention relates to a fully synthetic water-based metal cutting fluid and a preparation method. Background technique

[0002] Cutting fluid is an important supporting material for metal cutting. The purpose of using cutting fluid is to reduce the cutting force and the friction between the tool and the workpiece, take away the cutting heat in time, reduce the cutting temperature, reduce the tool wear, and improve the surface roughness of the workpiece. , so as to improve production efficiency and achieve the best economic effect.

[0003] With the continuous improvement of metal cutting technology, the continuous development of advanced machine tools, and the development of cutting tools and workpiece materials, the upgrading of cutting fluid varieties has been promoted. The cooling, stability and environmental protection of traditional oil-based cutting fluids have significantly lagged behind the development of modern cutting technology. Water-s...
