Abstract

The invention discloses a magnesium alloy cutting fluid and a preparation method thereof. Aiming at the characteristics of magnesium alloy, the magnesium alloy cutting fluid is prepared from base oil, modified oleamide, a chelating agent, an oil-soluble surfactant, fatty acid, silicate, an antirust agent and water according to a certain preparation method. The magnesium alloy cutting fluid disclosed by the invention has strong hard water resistance, and strong antiseptic property, lubricating property and anti-corrosion performance, is not easy to demulsify, and has high efficiency and long service life.

Description

technical field [0001] The invention relates to a cutting fluid and its preparation, in particular to a magnesium alloy cutting fluid and a preparation method thereof. Background technique [0002] In the process of metal processing, in order to reduce the cutting force during cutting, take away the heat generated in the cutting area in time to reduce the cutting temperature and prolong the durability of the tool, thereby improving production efficiency, improving the surface roughness of the workpiece, and ensuring the machining accuracy of the workpiece. For best economical results, metal cutting fluids are usually used. Therefore, the main function of cutting fluid has the following four aspects: lubrication, cooling, cleaning and rust prevention. [0003] The density of magnesium alloy is less than 2 / 3 of that of aluminum alloy and 1 / 4 of that of steel. It has high specific strength and specific stiffness, good dimensional stability, machinability, electrical and therma...
