Abstract

The invention relates to a long-life and low-foam emulsion for aluminium alloy cutting, belonging to the technical field of metal processing media. The emulsion has the beneficial effects that the lubricating capacity of cutting fluid and the surface finish of workpieces are improved by adopting combination of extreme pressure lubricants and oily lubricants; the alkali retention capacity and pH stability of the cutting fluid are improved by adopting optimized alcohol amine combination and through cooperation of monoethanolamine, triethanolamine and special alcohol amines; the requirements of different aluminium alloys for aluminium corrosion inhibition are achieved by adopting compound aluminium corrosion inhibitor combination and combining the characteristics of phosphorus-containing aluminium corrosion inhibitors and silicon-containing aluminium corrosion inhibitors; the stability of the cutting fluid primary fluid and a diluent is enhanced and adverse effects on machine tool paint are avoided by adopting special coupling agent combination; control of foam in a high pressure fluid supply system and a high precision filtering system is achieved by adopting the foam inhibition properties of the systems and the defoaming properties of defoaming agents.

Description

technical field [0001] The invention relates to a metal processing medium used as a metal processing medium for lubrication, cooling, cleaning and storage between processes to prevent corrosion during aluminum alloy cutting, in particular to a long-life low-foam emulsion for aluminum alloy cutting, which belongs to the metal processing medium technology field. Background technique [0002] Aluminum alloy has a series of excellent properties and is the most widely used non-ferrous metal structural material in industry. Aluminum alloy has good machinability and is an easy-to-machine material. However, during the cutting process, problems such as workpiece corrosion, discoloration, short tool life, substandard surface finish, large residue on the workpiece surface, and built-up edge are prone to occur. Especially the die-casting aluminum alloy contains silicon and copper. There are a large number of micropores distributed on the non-processed surface, the structure is relativ...
