Abstract

The invention discloses a high-wear-resistance modified-nano-molybdenum-disulfide-containing semisynthetic cutting fluid and a preparation method thereof. The invention is characterized in that the cutting fluid is prepared from the following raw materials in parts by weight: 3-8 parts of sulfur powder, 15-25 parts of organic hydramine, 5-10 parts of boric acid, 4-7 parts of oleic acid, 2-3 parts of sodium alginate, 2-4 parts of nano molybdenum disulfide, 5-12 parts of sodium dodecylsulfate, 2-3 parts of tungsten powder, 30-40 parts of palm oil, 5-9 parts of lauric acid, 2-3 parts of Span 80, 2-3 parts of Tween 80, 5-10 parts of paraffin base oil, 1-2 parts of polydimethylsiloxane and 50-100 parts of distilled water. The sodium alginate is utilized to disperse the nano molybdenum disulfide, so that the surface contains abundant functional groups; and the nano molybdenum disulfide has favorable compatibility after being added into the additives, thereby enhancing the wear resistance, extreme pressure performance and stability of the cutting fluid. The synthetic tungsten disulfide enables the lubricating oil to have higher wear resistance.

Description

technical field [0001] The invention relates to a semi-synthetic cutting fluid, in particular to a highly wear-resistant semi-synthetic cutting fluid containing modified nano molybdenum disulfide and a preparation method thereof. Background technique [0002] Semi-synthetic metal cutting fluid, also known as micro-emulsion metal cutting fluid, is diluted with water in a certain proportion, and the diameter of the emulsified particles is less than 1 μm. It is used in metal cutting and other processing industries. At the same time, it has good lubricity of emulsion and good synthetic fluid. It has excellent cleaning characteristics and suitable extreme pressure performance. It is a kind of cutting fluid with great development prospects; the main components of semi-synthetic metal cutting fluid are lubricating base oil (mineral oil), water, emulsifier, rust inhibitor, Extreme pressure anti-wear agent, defoamer, anti-mold and fungicide, etc. The content of emulsifier, mineral o...
