The cutting fluid comprises the following components in parts by weight: 40-50 parts of base oil, 7-10parts of an antirust agent, 5-8 parts of sulfonate, 3-6 parts of an emulsifier, 2-3 parts of alkylol amine, 5-8 parts of an oiliness agent, 0.5-3 part of a corrosion inhibitor, 0.01-4 part of a bactericide, 0.1-0.5 part of a coupling agent, 0.01-0.15 part of a defoaming agent and the balance being water.

Description

technical field [0001] The invention relates to a cutting fluid composition and its application. Background technique [0002] Aluminum alloy is one of the most widely used non-ferrous metals. It has low density, high strength, good processing performance and easy regeneration. It has been widely used in automobiles, aerospace, rail transit and other fields. However, the aluminum alloy has strong chemical activity, etc. During the processing, it will contact with the environmental medium water, air and the ions contained in it, and the corrosive products produced by the decomposition and oxidation of the cutting fluid, etc., and an electrochemical reaction will occur, causing the surface of the material to be corroded. Dark spots etc. Therefore, in order to protect the surface of the workpiece and have a good surface quality, the anti-corrosion effect of the machining fluid used in the cutting of aluminum alloy materials is very important. [0003] Cutting fluid generally ...
