Abstract

The invention discloses semi-synthetic cutting fluid containing modified nano-molybdenum disulfide 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: 15 to 25 parts of organic alkylol amine, 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, 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 paraffine-based oil, 1 to 2 parts of polydimethylsiloxane and 50 to 100 parts of distilled water. According to the semi-synthetic cutting fluid disclosed by the invention, the nano-molybdenum disulfide is dispersed by using the sodium alginate, and the surface of the nano-molybdenum disulfide is enabled to be rich in abundant functional groups; the sodium alginate is added into an additive to realize good compatibility, so that wear resistance, extreme pressure property and stability of the cutting fluid can be improved.

Description

Technical field [0001] The invention relates to a semi-synthetic cutting fluid, in particular to a 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 microemulsion metal cutting fluid, is diluted with water in a certain proportion, and the diameter of emulsified particles is less than 1μm. 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 is a kind of cutting fluid with great development prospect because of its cleaning characteristics and suitable extreme pressure performance. 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-fungal agent, etc. The content of emulsifier, mineral oil, and extreme pressure antiwear agent is ...
