Problems solved by technology

[0004] At present, lubricating oil companies at home and abroad are all committed to researching a magnesium alloy cutting fluid, but the magnesium alloy cutting fluid sold in the market is not resistant to hard water, and it is prone to demulsification and failure, or the corrosion resistance of magnesium alloy is not enough. , Magnesium alloys are prone to corrosion phenomena such as discoloration during processing, which affects their industrial applications.

Abstract

The invention relates to metal cutting liquid, in particular to magnesium alloy cutting liquid, which comprises basic oil, nonionic surfactants, anionic surfactants, antirust agents, lubricating agents, coupling agents, corrosion inhibitors and bactericide raw materials. The unique recipe in the invention has the advantages that magnesium alloy can no generate color change corrosion phenomena after being continuously soaked for more than 30 days at 55 DEG C in 5 percent diluent, the hydrogen release phenomenon of the magnesium alloy in water can be effectively inhabited, in addition, the hardwater resistance of the product is as high as 10000 ppm, and in addition, the work liquid can be used for more than half a year. At the same time, the invention has excellent performance such as rust prevention, lubrication, cooling and the like. In addition, the cutting liquid can be used for processing the magnesium alloy, and can also be used for processing metals such as aluminium alloy, cast iron, stainless steel and the like.

Description

Technical field: [0001] The invention relates to a metal cutting fluid, in particular to a magnesium alloy cutting fluid. Background technique: [0002] 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 thermal conductivity; It also has excellent performance in terms of shock resistance. Despite its abundant reserves and excellent structural properties, there is still a huge contrast between the application potential of magnesium as a structural material and the reality so far. The main reason for this situation is the corrosion of magnesium, that is, poor corrosion resistance is the bottleneck that restricts the potential of magnesium alloys. [0003] As a lightweight structural material, magnesium alloys have gained widespread attention in many fields such as automobiles, electronic appliances, and aviation. Wit...
