Abstract
The invention provides a cutting fluid preparing method, which belongs to a kind of antirust water-base cutting fluid, and is mainly used for cooling, lubricating, cleaning and rust preventing in the machine parts processing field. The invention aims at providing a preparing method for a kind of cutting fluid which has high antirust property, stable performance and long service period. The invention adopts the following technical proposal: 1, water-soluble boric acid ester and water-soluble molybdic acid ester are prepared; in a hermetic reaction kettle, under the condition of 90-180 DEG C, diethanolamine, boric acid and alcohol react, and molybdic acid ester is prepared; 2, The weight percentages of the constituents: boric acid ester is 8-10, antirust is 4-10, molybdic acid ester is 2-4, foam suppressor is 1-3, oleic acid is 0.5-2, emulsifier is 10-18, triethanolamine is 5-8, osmotic agent is 2-3, benzoate is 2-4, and water is the rest.
Description
Technical field:
The present invention belongs to a kind of anti-rust water-based cutting fluid, is mainly used in the cooling of mechanical component manufacture field, lubricated, cleaning and antirust.
Background technology:
At present, the cutting fluid of mechanical processing industry use has machining oil and emulsion two classes.Machining oil can produce a large amount of oil smoke in high-temperature machining is produced, both contaminate environment influenced safety in production again; And machining oil needs stoste cutting, production cost height; Be that rustless property is poor again, even part get final product corrosion after 1～2 hour.Emulsion is a kind of mixed aqueous solution, and the animal and plant grease that contains in the emulsion is very easily rotten, poor stability; Breakdown of emulsion in use easily takes place, and not only life cycle is short, and the waste liquid environmental pollution is serious.
Summary of the invention:
The present invention is exactly at the problems referred to above, provides a kind of rust-preventing characteristic good, stable performance, the preparation method of the cutting fluid that life cycle is long.
The present invention adopts following technical scheme:
1, preparation water-soluble boron acid esters, water-soluble molybdates esters:
In closed reactor, under 90～180 ℃ of conditions, diethanolamine, boric acid, alcohol reaction make boric acid ester;
In closed reactor, under 90～180 ℃ of conditions, diethanolamine, amine molybdate, elaidin reaction make molybdates esters;
2, the weight percentage in the component:
Boric acid ester 8～10 rust-preventive agent 6～10
Molybdates esters 2～4 defoamers 1～3
Oleic acid 0.5～2 emulsifying agent 10～18
Trolamine 5～8 permeate agents 2～3
Benzoate 2～4 water surplus
Described rust-preventive agent comprises phytic acid or higher fatty acid.
Described emulsifying agent comprises nonionic surface active agent OP or AEO.
Described alcohol is methyl alcohol, ethanol or butanols.
Beneficial effect of the present invention:
Contain water-soluble boron acid esters and water-soluble molybdates esters in the cutting fluid of the present invention, they can provide good oilness and extreme pressure property for cutting fluid.Process pyroreaction parts such as dispersive oleic acid, trolamine, benzoate, permeate agent, rust-preventive agent, defoamer are converted into soluble ester in the water, another part is under the effect of emulsifying agent, be dispersed in uniformly in the water with the colloidal solid state, can guarantee that cutting fluid has good penetration, preservative property and rust-preventing characteristic.Cutting fluid of the present invention is never degenerated at normal temperatures, but life-time service.
Embodiment:
Embodiment:
1, the preparation of boric acid ester and molybdates esters: in closed reaction kettle, control reaction temperature is 90～180 ℃, makes water-soluble boron acid esters and water-soluble molybdates esters respectively.Each component concentration is as follows in boric acid ester and the molybdates esters:
