Description
Technical field
The present invention relates to cutting fluid technical field, particularly, relate to a kind of settleability water-base cutting fluid and preparation method thereof.
Background technology
Modern mechanical processing progressively at a high speed, powerful, meticulous future development, and the use of the difficult-to-machine materials such as superhard, super-strength also makes the difficulty of machining day by day increase.Cause the frictional force in machining thus, heat of friction increases considerably, this just requires that metal working fluid has better smooth, cooling, cleaning, antirust function, to obtain desirable workpiece machining surface.Wherein, mineral oil smooth, antirust ability is excellent, but cooling, cleaning function is poor; The cooling of emulsion and water-base cutting fluid, cleaning function are better, but smooth, antirust function is poor, therefore uses limitation to be limited.
Therefore, develop and a kind ofly there is excellent smooth and water-base cutting fluid that is rustless property be of great immediate significance.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of settleability water-base cutting fluid and preparation method thereof, this water-base cutting fluid not only has excellent cooling, cleaning function, and its smooth and antirust function also arrives or surmounts the code requirement of emulsion, can be used for clockwork processing.
Present invention also offers the preparation method of described water-base cutting fluid.
Technical scheme of the present invention is as follows: a kind of settleability water-base cutting fluid, comprises following each group by mass percentage:
The preparation method of described nonionogenic tenside H is: under catalyzer under existence condition, it is liquid that the natural rosin of solid is heated to 160-200 DEG C of melting, add maleic anhydride polymerization reaction take place and obtain multipolymer maleated rosin, then maleated rosin again with polyamine generation neutralization reaction, obtain described nonionogenic tenside H.Described polyamine is 3,3 '-two chloro-4,4 '-diphenylmethanediamiand (MOCA) and propylene glycol be two-(4,4 ' one diamino) benzoic ether in one or its mixture.
The preparation method of described triethanolamine oleate ester is: under the reaction conditions of 130-160 DEG C, and be oleic acid and the trolamine mixing of 1:3 by mol ratio ,-OH group generation the esterification of-COOH the group in oleic acid and trolamine, generates triethanolamine oleate ester.Triethanolamine oleate ester is excellent water-soluble oiliness improver, detects through four-ball tester, and the last non seizure load PB value of the triethanolamine oleate aqueous solution of ester of 5% can reach 700N, measures its frictional coefficient 0.070 with MPV-200 friction wear testing machine.
Described organosulfur is the mixture of one or several in mercaptan, thiophenol, thioether, disulphide, polysulfide or cyclical sulfide.
Described extreme pressure anti-wear additives is the mixture of one or several in sulfide isobutene, benzyl disulfide, sodium metaborate, potassium metaborate, three potassium borates, sodium tetraborate and sodium phosphate.
Described sanitas is cutting fluid sanitas DL602 and N-360.
Described settleability water-base cutting fluid is also containing flocculation agent, and described flocculation agent is selected from polymerize aluminum chloride (PAC), polyaluminium sulfate (PAS), poly-ferric chloride (PFC) and bodied ferric sulfate (PFS) or its any mixture.
The preparation method of water-base cutting fluid of the present invention, comprises the steps:
Prepare nonionogenic tenside H: under catalyzer under existence condition, it is liquid that the natural rosin of solid is heated to 160-200 DEG C of melting, add maleic anhydride polymerization reaction take place and obtain multipolymer maleated rosin, then maleated rosin again with polyamine generation neutralization reaction, obtain described nonionogenic tenside H;
Prepare triethanolamine oleate ester: under the reaction conditions of 130-160 DEG C, be oleic acid and the trolamine mixing of 1:3 by mol ratio ,-OH group generation the esterification of-COOH the group in oleic acid and trolamine, generates triethanolamine oleate ester;
Measure described nonionogenic tenside H by formula, described triethanolamine oleate ester, organosulfur, extreme pressure anti-wear additives, sanitas and water mix, then measure defoamer and mix, and obtain described water-base cutting fluid.
In metal cutting process, great majority friction belongs to boundary lubrication friction.In boundary lubrication friction, owing to there is not oil film completely, its supporting capacity has nothing to do with oil viscosity, and depends on the oiliness of lubricating oil, namely whether Lubrication Composition contains atomic group metal being existed to strong adsorption, can form physics adsorption film at cutting interface.Polar group in nonionogenic tenside H has larger affinity ability to metal, is easy to be adsorbed on metallic surface, forms adsorbed lubricating film.Because its hydrophobic grouping is comparatively large, and there is aromatic ring structure, there is the effect of oiliness improver.Nonionogenic tenside contains the nonactive extreme pressure element of N simultaneously, and it has the double effects of oiliness improver and extreme pressure agent concurrently.Act synergistically with the extreme pressure anti-wear additives added again, form high strength physics and chemistry adsorption film, make it to be unlikely to destroy under high pressure, high temperature and fierce rubbing effect.Can prevent or reduce the direct contact between workpiece, cutting, cutter three, reach the target reducing friction and bonding, play fabulous lubrication.Triethanolamine oleate is a kind of positively charged ion appearance promoting agent, is added in cutting fluid, easily between cutlery and cutting workpiece, forms physics adsorption film, then play lubrication as oiliness improver.Other, triethanolamine oleate and extreme pressure anti-wear additives also have superior collaborative wear-resistant effect, may also be lubricity and significantly improve.
The quality of cutting fluid cleaning function, tightly relevant with mobility to the impregnability of cutting fluid, appearance tension force is low, the cutting fluid of perviousness and good fluidity, and cleaning function is all right.Containing nonionic appearance promoting agent H and positively charged ion appearance promoting agent triethanolamine oleate in water-base cutting fluid of the present invention, the two coordinative role, significantly reduce the appearance tension force of cutting fluid, enhance perviousness and the mobility of cutting fluid, thus there is good cleaning performance.
The cooling performance of cutting fluid, depends on its thermal conductivity, specific heat, vaporization heat and vaporization rate etc.The thermal conductivity of water is 3 ~ 5 times of oil, and specific heat is 2 ~ 2.5 times of oil, and the refrigerating function of Gu Shui is winning more much than oil.Containing the moisture of more than 90% in water-base cutting fluid of the present invention, so refrigerating function is given prominence to.
Nonionic appearance promoting agent H self of the present invention has antirust and preservative effect, with sanitas generation composite synergistic effect, Adsorption Dimension cuticular layer is formed at metal package, passivation film, then block cathode and anode and corrode process, because there is fine and close shoe epiphragma, usefully can resists the immersion of water molecules, oxygen and other aggressive substances in medium, there is outstanding anticorrosion, antirust function.
Settleability water-based milling liquid of the present invention, containing organosulfur, the metal-powder that organosulfur and hone produce reacts, form stable organometallic compound, not soluble, thus precipitation is formed and separated removal in cutting fluid, described flocculation agent promotes that the organometallic compound generated is assembled and precipitates, thus ensure that the oilness of cutting fluid and the permanent stability of cleaning performance.
Settleability water-base cutting fluid of the present invention is with the nonionic appearance promoting agent H of the raw material compositions such as rosin, maleic anhydride and polyamine, the water-base cutting fluid formulated with compounds such as triethanolamine oleate esters, there is excellent slipperiness, rust-preventing characteristic, cooling and cleaning, be applicable to the turning of Construction Steel, grinding and boring, dilute with water 3 times during utilization.
