Nano-silver-containing antibacterial semi-synthetic cutting fluid and preparation method thereof

Abstract

The invention discloses nano-silver-containing antibacterial semi-synthetic cutting fluid and a preparation method thereof. The nano-silver-containing antibacterial semi-synthetic cutting fluid is characterized by being prepared from the following raw materials in parts by weight: 1-2 parts of nano-silver, 15-25 parts of organic alkylol amine, 5-10 parts of boric acid, 8-15 parts of a chitosan cation glue solution, 4-7 parts of oleic acid, 2-3 parts of sodium alginate, 2-4 parts of nano molybdenum disulfide, 3-5 parts of glutaraldehyde, 5-12 parts of Sodium laurylsulfonate, 3-5 parts of an Arabic gum water solution, 30-40 parts of palm oil, 5-9 parts of lauric acid, a proper amount of a sodium hydroxide solution, 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. As the nano molybdenum disulfide is dispersed by using the sodium alginate, the surface of the nano molybdenum disulfide has rich functional groups, very good compatibility can be achieved when the mixture of the nano molybdenum disulfide and the sodium alginate is added into an additive, and thus the wearing resistance, the extreme pressure property and the stability of the cutting fluid can be improved; due to addition of the nano-sliver, the cutting fluid has antibacterial activity.

Description

technical field [0001] The invention relates to a semi-synthetic cutting fluid, in particular to a semi-synthetic cutting fluid containing nano-silver antibacterial 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 pressure antiwea...
