Embodiment Construction
[0021] The present invention will be further described below in conjunction with specific examples.
[0022] The formula composition of fully synthetic cutting fluid of the present invention is by weight:
[0023]
[0024]
[0025] As a preferred embodiment, the formula components of the fully synthetic cutting fluid in this embodiment are by weight:
[0026]
[0027] The polyol esters are generally soluble in water, and most polyols are viscous liquids or crystalline solids with high boiling point, strong dissolving ability for polar substances, and low toxicity and volatility. Its boiling point, viscosity, relative density and melting point increase with the increase of molecular weight, and it has strong crystallinity and high bonding strength.
[0028] Span 80 (Span 80) is a yellow oily liquid, dispersible in warm water and ethanol, soluble in organic solvents such as propylene glycol, liquid paraffin, ethanol, methanol or ethyl acetate, HLB=4.3, often used as wa...

Abstract
The invention discloses fully-synthetic cutting liquid and a preparation method thereof. The fully-synthetic cutting liquid is composed of, by weight, 10-15% of polyol ester, 6-8% of Span 80, 4-6% of triethanolamine, 3-5% of tall oil, 10-15% of sebacic acid, 3-5% of ethylene glycol, 2-3% of dispersant, 0.5-1% of defoamer, 0.1-0.2% of IPBC and 52-55% of water. The preparation method includes following operation steps: a, adding 12% of polyol ester into a reaction kettle, and heating to 90 DEG C; b, stirring at a rotating speed of 1500rpm, sequentially adding, by weight, 5% of tall oil, 12% of sebacic acid, 5% of triethanolamine and 7% of Span 80 and water accounting for 20% of total mass, increasing temperature of the reaction kettle to 135 DEG C, stirring at constant temperature for 30min until thick substance is formed, adding 3% of ethylene glycol, 2.5% of the dispersant and the balance of 32.8% of water, continuing heating, and stirring; c, cooling to normal temperature, sequentially adding 0.5% of the defoamer and 0.2% of IPBC, and stirring for 15min.
Description
[0001] Technical field: [0002] The invention relates to the technical field of metal processing coolant products, in particular to a fully synthetic cutting fluid and a preparation method thereof. [0003] Background technique: [0004] With the rapid development of China's industry and the continuous exploration and improvement of metal processing technology, more stringent requirements have been put forward for the lubrication technology in the metal processing process. The main metal processing lubricants in the existing market are oily cutting oil and emulsified oil. , mostly semi-synthetic liquid. [0005] Cutting fluid (coolant) is an industrial liquid used in metal cutting and grinding to cool and lubricate cutting tools and workpieces. Cutting fluid is made of a variety of super functional additives through scientific compounding At the same time, it has good cooling performance, lubricating performance, anti-rust performance, degreasing and cleaning function, anti-c...
