Abstract

The invention discloses a water-soluble minimum quantity lubricating liquid containing MoS2. The lubricating liquid comprises the following components in percentage by weight: 2-20% of nano MoS2, 10-30% of a lubricant, 1-5% of a dispersing agent, 2-20% of a surfactant, 0.05-0.5% of a defoaming agent, 0.05-5% of a preservative, 0.05-5% of a descaling agent, 1-5% of an antirust agent and the balanceof deionized water, wherein the sum of the weight percentages of the nano MoS2 and the nano cubic boron nitride is 3-30%; the particle size distribution of the nano MoS2 is 20-150nm, the average particle size is 50-80nm, and the specific surface area is 50-150 m<2>/g; the particle size distribution of the nano cubic boron nitride is 50-200 nm, and the average particle size is 70-80 nm. The lubricating liquid has the characteristics that molybdenum disulfide is small in particle size and uniform in distribution, precipitation, blockage and other faults are not likely to be formed, fog drops can be efficiently formed, the molybdenum content in the lubricating liquid is high, and the lubricating effect is good.

Description

technical field [0001] The invention belongs to the technical field of lubricating fluid and lubricating fluid additives, and relates to a MoS-containing 2 Water-soluble micro lubricant; especially suitable for drilling, reaming, tapping, deep hole drilling, aluminum alloy face milling and other processing of cast iron, steel and aluminum alloy. Background technique [0002] The concept of minimal quantity lubrication was first proposed in 1996 by two scholars, W.D.Hewson and G.K.Gerow of Michigan Technical University. The application of minimal quantity lubrication technology began in the late 1990s in some foreign industrial powers. At the beginning, it was limited to the field of casting processing, and then gradually expanded to non-ferrous metals such as steel and aluminum parts. [0003] Minimal quantity lubrication is an emerging green manufacturing technology. It is to mix a small amount of lubricant in high-pressure gas, and enter the high-temperature cutting area ...
