Abstract

The invention provides a semi-synthetic stainless steel cutting fluid. The semi-synthetic stainless steel cutting fluid is prepared from the following raw materials in parts by weight: 10-30 parts ofbase oil, 3-8 parts of an active sulfur extreme pressure agent, 5-10 parts of an inactive sulfur extreme pressure agent, 4-8 parts of a phosphate extreme pressure agent, 8-15 parts of polyfatty acid ester, 3-5 parts of a low-alkali calcium sulfonate rust inhibitor, 8-15 parts of an emulsifier, 0.5-3 parts of an isomeric alcohol coupling agent, 5-15 parts of a pH stabilizer, 0.5-3 parts of an isothiazolinone microbicide, 0.1-2 parts of a silicone defoamer, and 15-30 parts of distilled water. Beneficial effects are as follows: the semi-synthetic stainless steel cutting fluid provided by the invention has excellent lubrication, extreme pressure and cooling performance, can effectively solve the problems of short tool life and poor surface quality of workpiece in the process of stainless steelprocessing, and does not contain formaldehyde releasing bactericides and chlorinated paraffin, and is safe to human health.

Description

technical field [0001] The invention relates to a semi-synthetic stainless steel cutting fluid and a preparation method thereof. Background technique [0002] Stainless steel has many advantages such as high tensile strength, high elongation, strong corrosion resistance, good wear resistance, good heat resistance, good chemical compatibility, etc., and has been widely used in aerospace, instrumentation, daily necessities, etc. each field. During the cutting process of stainless steel, it is easy to have high cutting temperature, short tool life and low surface quality of the workpiece. According to the characteristics of stainless steel cutting, the cutting fluid must have excellent lubricating extreme pressure and cooling performance. [0003] Stainless steel cutting fluid can be divided into four types: cutting oil, emulsified oil, semi-synthetic, and fully synthetic. The cooling performance of the cutting oil is poor, and it is easy to produce cutting oil smoke and oil...
