Problems solved by technology

The composition of the cutting fluid is complex, and there are toxic substances such as fluoboric acid and stannous octoate, which are irritating to the eyes, skin, mucous membranes and upper respiratory tract; harmful to the environment and can cause pollution to water bodies
[0008] CN106833853A discloses a water-soluble cutting fluid, which contains the following components in parts by weight: 4% boric acid, 1% dodecanoic acid, 0.1% benzotriazole, 7% triethanolamine, 4% monoisopropanolamine %, tall oil 6%, tetrameric ricinoleic acid 3%, sodium petroleum sulfonate 3%, mineral oil 36%, synthetic fat 5%, aluminum corrosion inhibitor 0.5%, MBM fungicide 2%, emulsifier 2% , water 26.4%, mineral oil is used in the formula, and the biodegradability is poor. In addition, it can be seen from the formula that the mass content of water in this cutting fluid is 26.4%, and the mass content of other solutes is 78.6%, and the cost is high.

Abstract

The invention relates to a water-based cutting fluid and a preparation method thereof, wherein the water-based cutting fluid comprises the following components in parts by weight: 0.5-3 parts of organic alcohol amine, 2-10 parts of tung oil dimer acid, 2-3 parts of preservative, 0.1-0.5 part of benzotriazole, 0.1-0.6 part of a water softener and 82.9-95.3 parts of water. The invention also provides a preparation method of the water-based cutting fluid. The water-based cutting fluid provided by the invention has excellent lubricating, anti-corrosion and anti-rust effects, is an environment-friendly water-based cutting fluid, has good biodegradability and is suitable for various grinding machine machining processes. Compared with the existing cutting fluid, the cutting fluid of the inventionis low in solute mass content, environment-friendly and economical.

Description

technical field [0001] The invention belongs to the technical field of cutting fluid, and in particular relates to a water-based cutting fluid and a preparation method thereof. Background technique [0002] Cutting fluid (coolant) is an industrial liquid used in metal cutting and grinding processes to cool and lubricate cutting tools and workpieces. Modern machining is developing towards high speed, strength and precision, and the development of hard-to-machine materials such as super-hard and super-strength also makes cutting more difficult. These two reasons lead to a substantial increase in friction and friction heat in the cutting process, which requires metalworking fluids to have better lubrication, cooling, cleaning, and anti-rust properties in order to obtain an ideal machined surface. [0003] Mineral lubricating oil has excellent lubricating and anti-rust performance, but poor cooling and cleaning performance, causing great environmental pollution; emulsion and wa...
