Abstract

The invention discloses a preparation method of a microemulsion cutting fluid with good oil extraction performance. The method comprises steps of: 1) adding 7-9% of boric acid, 5-7% of diethanol amine, 4-6% of triethanolamine and water in a certain proportion into a reaction tank, and stirring at 40-50 DEG C for 20-30 min; 2) successively adding 5-7% of petroleum sodium sulfonate with concentration of 60%, 6-8% of fatty alcohol-polyoxyethylene ether, 5-7% of sulfonated castor oil soap, 8-10% of polyol oleate, 3-5% of sulfurized aliphatic ester, 0.3-0.5% of benzotriazole and 0.2-0.4% of emulsified silicone oil into 10-12% of naphthenic oil at 40-50 DEG C, and stirring for 30-40 min; and 3) cooling the mixture obtained in the step 2 ) to 30-35 DEG C, then adding the mixture from the step 1), and stirring for 60-90 min.

Description

Technical field [0001] The invention relates to the technical field of metal cutting processing, in particular to a preparation method of a microemulsion cutting fluid with good oil drainage. Background technique [0002] Cutting fluids are divided into two categories: non-water-soluble (oil-based) fluids and water-soluble (water-based) fluids according to the chemical composition of the oil. The oil-based cutting fluid has better lubrication performance and poor cooling effect. Compared with oil-based cutting fluid, water-based cutting fluid has relatively poor lubrication performance and better cooling effect. [0003] Emulsion combines the lubricity and anti-rust properties of oil with the excellent cooling properties of water, and at the same time has good lubrication and cooling properties, so it is very effective for high-speed and low-pressure metal cutting with a large amount of heat. Compared with oil-based cutting fluids, the advantages of emulsions are greater heat dis...
