Abstract

The invention discloses semi-synthetic cutting fluid containing nano-molybdenum disulfide and having high cooling performance, and a preparation method of the semi-synthetic cutting fluid. The semi-synthetic cutting fluid is characterized by being prepared from the following raw materials in parts by weight: 2 to 3 parts of nanometer aluminum oxide, 15 to 25 parts of organic alcohol amine, 3 to 5 parts of a silane coupling agent KH, 5 to 10 parts of boric acid, 4 to 7 parts of oleic acid, 2 to 3 parts of sodium alginate, 2 to 4 parts of nano-molybdenum disulfide, 10 to 20 parts of xylene, 5 to 12 parts of sodium dodecyl sulfate, 30 to 40 parts of palm oil, 5 to 9 parts of lauric acid, 2 to 3 parts of span 80, 2 to 3 parts of tween 80, 5 to 10 parts of paraffinic based oil, 1 to 2 parts of dimethyl silicone polymer and 50 to 100 parts of distilled water. According to the method, the nano-molybdenum disulfide is dispersed by the sodium alginate, so that the surface of the nano-molybdenum disulfide is enriched with functional groups; when added into the additive, the nano-molybdenum disulfide is extremely high in compatibility, so that the abrasive resistance, the extreme pressure property and the stability of the cutting fluid can be improved; the cooperatively added nanometer aluminum oxide improves the cooling performance of the cutting fluid.

Description

technical field [0001] The invention relates to a semi-synthetic cutting fluid, in particular to a semi-synthetic cutting fluid containing modified nanometer 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 oil and extreme pr...
