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.

Embodiment 1

[0037] Take 100g of commercial eleostearic acid (purchased from Anhui Ruifand Oil Deep Processing Co., Ltd., model: T160) and place it in a 250mL four-necked flask, add 0.5g of tert-butyl hydroquinone at the same time, purge with nitrogen for 30min, and stir at 300rpm. The temperature was raised to 220° C. to react for 4 h, the heating was stopped, and the mixture was cooled to room temperature in ice water to obtain a crude dimer acid product. The molecular distillation apparatus controls the temperature at 150 °C, the pressure is less than or equal to 2Pa, and the heavy component product is collected; the heavy product is distilled again, and the molecular distillation apparatus is controlled to control the temperature at 250 °C and the pressure is less than or equal to 2Pa. The outflow light components are tung oil dimer acid, two Polyacid content ≥98%.

Abstract

The invention relates to a water-based cutting fluid and a preparation method thereof, comprising: 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, and benzotriazole 0.1-0.5 parts, 0.1-0.6 parts of water softener, 82.9-95.3 parts of water. The present invention also provides a preparation method of the above-mentioned water-based cutting fluid. The water-based cutting fluid provided by the invention has excellent lubricating, anti-corrosion and anti-rust effects, is a green and environment-friendly water-based cutting fluid, has good biodegradability, and is suitable for various grinding machine processing techniques. Compared with the existing cutting fluid, the solute mass content is low, and it is environmentally friendly and economical.

Description

technical field [0001] The invention belongs to the technical field of cutting fluid, and particularly 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 to cool and lubricate tools and workpieces. Modern machining is developing in the direction of high speed, strength and precision. The development of difficult-to-machine materials such as super-hard and super-strength has also increased the difficulty of cutting. These two reasons lead to a significant increase in the frictional force and frictional heat during the cutting process, which requires the metalworking fluid to have better lubrication, cooling, cleaning, and rust-proof 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...
