According to the invention, as the special molecular structure of the modified polymerized ricinoleic acid is skillfully utilized in the formula of the cutting fluid, the bubble releasing speed of the cutting fluid in the soft water is effectively increased, and the stability and lubricating property of the cutting fluid are greatly improved.
Description
Technical field
The present invention relates to a kind of metal working fluid, relate in particular to a kind of water-based metal processing cutting fluid that is adapted to soft water.
Background technology
Along with the high speed development of the industries such as electronics, automobile, aerospace, new forms of energy and weight equipment, the extensive concern and the attention that also more and more obtain industry of developing its metalworking technology that adapts with it.And metal working fluid is as the important component part in the process of metal working, plays a part indispensable to raising and the development of metalworking technology.In general, metal working fluid is divided into oil base and water base two large classes.From the market service condition, the consumption of water based product is increasing year by year.But water-base cutting fluid is responsive to the quality of on-the-spot water quality.Water such as high rigidity can cause cutting fluid unstable, thereby has influence on the surface quality of processing work, reduces the life-span of cutter and emery wheel.Contaminated water can cause growing of emulsion bacterium or mould, thereby affects the performance of cutting fluid.
Therefore, in order to improve better efficient and the quality of processing, at present increasing manufacturing enterprise brings into use the softening water of processing when the applying waterborne cutting fluid.Yet traditional water-based cutting fluid is when diluting with soft water, and it is many to produce foam, instability of flow, the performance deficiencies such as lack of lubrication.
Summary of the invention
The object of the invention is to overcome the defective of prior art and a kind of water-based metal processing cutting fluid that is adapted to soft water is provided, to solve the high bubble of on-the-spot cutting fluid, unstable, the problem such as processing characteristics is not good.
The object of the present invention is achieved like this:
A kind of water-based metal processing cutting fluid that is adapted to soft water of the present invention, it is composed of the following components by weight percentage: base oil 20-45%, modified poly ricinolic acid 5%-15%, nonionogenic tenside 0.5-5%, anion surfactant 5-15%, synthetic ester 5-15%, coupling agent 1-6%, additive 1-5%, surplus is water.
Above-mentioned a kind of water-based metal processing cutting fluid that is adapted to soft water, wherein, described base oil is mineral oil, poly-alpha olefins, ethene-poly-alpha olefins, rapeseed oil, plam oil or soybean oil.
Above-mentioned a kind of water-based metal processing cutting fluid that is adapted to soft water, wherein, described modified poly ricinolic acid be polymerized castor oil acid with the polyoxyethylene glycol of terminal hydroxy group and at least a reaction product in the polyoxyethylene poly-oxygen propylene aether.
Above-mentioned a kind of water-based metal processing cutting fluid that is adapted to soft water, wherein, described nonionogenic tenside is selected from least a in fatty alcohol-polyoxyethylene ether, aliphatic alcohol polyethenoxy polyethenoxy ether, alkylphenol polyoxyethylene and the polyoxyethylene carboxylate.
Above-mentioned a kind of water-based metal processing cutting fluid that is adapted to soft water, wherein, described anion surfactant is selected from least a mixture at least a and monoethanolamine in oleic acid, appropriate youngster's oleic acid, ricinolic acid, dimeracid, the isomery stearic acid, trolamine, α-amino isopropyl alcohol, N methyldiethanol amine, dicyclohexyl amine, the 2-amino-2-methyl-1-propanol.
Above-mentioned a kind of water-based metal processing cutting fluid that is adapted to soft water, wherein, described synthetic ester is selected from least a in iso-octyl palmitate, isooctyl oleate, isoamyl diol ester, Glycerin ester, the pentaerythritol ester.
Above-mentioned a kind of water-based metal processing cutting fluid that is adapted to soft water, wherein, described coupling agent is Virahol, propylene glycol, methoxyl group-propoxy--propyl alcohol or butyl glycol ether.
Above-mentioned a kind of water-based metal processing cutting fluid that is adapted to soft water, wherein, described additive is selected from least a of sterilant, rust-preventive agent, defoamer and inhibiter.
Above-mentioned various feed composition are added under 20-50 ℃ of temperature successively one by one and stir, it is mixed, can obtain product of the present invention.
The present invention has utilized the special molecular structure of modified poly ricinolic acid dexterously in the cutting fluid prescription, effectively accelerated the release bubble speed of cutting fluid in soft water, and has increased substantially stability and the oilness of cutting fluid.
The modified poly ricinolic acid has the larger hydrophobic grouping of molecular weight on the one hand, and contains two keys, and molecular structure is irregular, and all there is hydrophilic polymer segment at part molecule two ends on the other hand.When it formed foam in the aqueous solution, its surface molecular was difficult to form closely and arranges, thereby caused the intensity difference of liquid film, and therefore formed foam is unsettled, vanishes easily.But this material is hydrophobic simultaneously-and hydrophilic-hydrophobic structure makes again emulsification system more stable, prolonged the life-span of cutting fluid.In addition, still keep many polar groups on the molecular structure of its long-chain section, can form in the metallic surface lubricant film of some strength, add compound with other component, improved well the lubricity of cutting fluid of the present invention.
Cutting fluid of the present invention and traditional product have been carried out the contrast test of foam and lubricity.Wherein foaming properties is the recycle pump experiment test.Concrete grammar circulated 20 hours for product is diluted in soft water, measured its foam height and foam time.Lubricity is the tapping torsion-testing.
Foaming properties contrast test result following (soft water, 8% concentration):
| Traditional product | Cutting fluid of the present invention | |
| Foam height (mm) | 80 | 50 |
| Foam time (min) | 30 | 15 |
Lubricity contrast test result following (soft water, 8% concentration)
| Tapping torque value (Ncm) | Traditional product | Cutting fluid of the present invention |
| Aluminium workpiece (Al 356) | 120 | 100 |
| Ironworker's part (CK45) | 145 | 115 |
From above contrast test result's data, can find out, cutting fluid of the present invention in soft water self froth breaking or press down bubble and can the force rate traditional product improve more than 30%, lubricity all has significantly raising in aluminium processing and ironworking.
