Description

A kind of aqueous cutting fluid of high rust resistance
Technical field
The present invention relates to metal working technical area more particularly to a kind of aqueous cutting fluids of high rust resistance.
Background technology
Metalworking fluid refer to cut, cut for metal, grinding, common a kind of industrial type fluid in the process such as milling, The friction between cutter and workpiece can be reduced, and takes away processing district internal cause friction in time, the heat that material deformation generates, to reach To the effect for improving processing efficiency, improving workpiece accuracy, reduction workpiece surface roughness and extension cutter life.Due to cutting Processing technology is one of mainstay of machinery manufacturing industry, accounts for about the 30-40% that mechanical processing is always worked, the weight of metalworking fluid The property wanted has some idea of.
The performance of cutting fluid depends on its constituent, and cutting fluid is usually divided into water-insoluble (oil base) liquid and water-soluble Property (water base) liquid two major classes.The greasy property of oil base cutting fluid is preferable, and cooling effect is poor.Water-base cutting fluid and oil base cutting fluid Relatively poor compared to greasy property, cooling effect is preferable.But since oil base cutting fluid is of high cost and pollutes relatively tight Weight, thus it is the developing direction of cutting fluid to have the water-base cutting fluid product of environmental type performance, the abundance of water, and nothing Poison is tasteless, is ideal green basal liquid, but the antirust of presently commercially available water-base cutting fluid, greasy property are not ideal enough, from And limit its application.
Invention content
Based on background technology there are the problem of, the present invention proposes a kind of aqueous cutting fluid of high rust resistance, Environmentally protective and lubricity of the invention is good, high rust resistance.
The present invention proposes a kind of aqueous cutting fluid of high rust resistance, includes by weight：Naphthenic base 15-35 parts oily, 3-12 parts of composite antirust agent, 4-8 parts of diethanol amine borate, 2-5 parts of thiocarbamide, 12-16 parts of triethanolamine oleate, 8-14 parts of polyethylene glycol, 1-8 parts of aminomethyl propanol, 0.2-2 parts of dimethicone, 0.3-2 parts of methyl benzotriazole, di-2-ethylhexylphosphine oxide 0.2-1 parts of quinoline, 20-50 parts of water.
Preferably, the composite antirust agent by organic acid triethanolamine, polyvinyl alcohol, borax by weight 20-25：12- 16:6-9 is compounded.
Preferably, the organic acid triethanolamine can be synthesized by following methods：After sebacic acid and triethanolamine are mixed, water Bath is heated and is stirred always, and reaction temperature controls between 80-87 DEG C, after reacting 35-45min, is cooled to room temperature to get product Organic acid triethanolamine.
Preferably, in the synthesis of the organic acid triethanolamine, the amount of the sebacic acid of addition and the substance of triethanolamine it Than being 1: 3.
Preferably, the aqueous cutting fluid of the high rust resistance includes by weight：Naphthenic base oils 20-30 parts, it is 5-10 parts of composite antirust agent, 5-7 parts of diethanol amine borate, 3-4 parts of thiocarbamide, 13-15 parts of triethanolamine oleate, poly- 10-12 parts of ethylene glycol, 3-8 parts of aminomethyl propanol, 0.4-1.8 parts of dimethicone, 0.5-1.8 parts of methyl benzotriazole, methylene Double morpholine 0.3-0.9 parts, 25-45 parts of water.
The present invention selects naphthenic base oils, it has, and biological degradability is high, the scope of application is wide, good compatibility, toxicity are low, The advantages that cost is relatively low can significantly improve the lubricity of cutting fluid；The composite antirust agent that the present invention is added is with sebacic acid and three The reaction product of ethanol amine is main component, since the product contains great amount of hydroxy group, amido and ester group isopolarity group, to metal There is stronger affinity, metal surface can be preferentially adsorbed on, show good rust-preventing characteristic, then coordinate addition polyvinyl alcohol, uses To promote the formation of rust-preventing film, antirust agent is prevented to be lost in from metal surface, and it is more secured so that antirust agent is adhered in metal surface, It is eventually adding borax, thickening and anti-rust action can be further functioned as；Diethanol amine borate, thiocarbamide is added as pole in the present invention Pressure lubricating agent, wherein diethanol amine borate can form the interstitial compound of boron in metal cutting process in metal surface, And this interstitial compound can also dissolve the boron of free state, form solid solution, to form complicated infiltration in friction surface Layer, in metal surface microscopic concavities part, keeps rubbing surface more smooth, smooth as high rigidity microadsorption ball filling, from And friction-reducing and antiwear action is played, and thiocarbamide contains C=S keys, under condition of boundary lubrication, can generate the inoranic membrane of sulfur-bearing, at this Under the synergistic effect of several films, play the role of wear-resistant, the lubrication present invention using triethanolamine oleate and polyethylene glycol as table Face activating agent does not corrode workpiece not only, but also nonionic triethanolamine oleate and anionic polyethylene glycol compounding can rise To synergistic effect, make the present invention that there is low surface tension, there is good wettability, is lubricated to improve the present invention, is cold But and cleaning performance；The present invention is also added into aminomethyl propanol, dimethicone, methyl benzotriazole, di-2-ethylhexylphosphine oxide morpholine can To significantly improve basicity stability, the lubricating and antirust of cutting liquid system, the suds of cutting liquid system can also be improved and disappeared Bubble property can also effectively inhibit cutting fluid corrupt, to significantly improve the service life of cutting fluid；Generally speaking, the present invention with Naphthenic base oils compound composite antirust agent, extreme-pressure lubricant, surfactant, antifoaming agent, fungicide, pH adjusting agent, make it There is good lubrication, wear-resistant, antirust and cleaning function in process, and it is not blistering, chip removing is good, is stale-proof not Smelly, long working life, thus process after workpiece surface roughness it is low, without organic substance residues, and place for a long time do not return rust, So as to meet the machining requirement to metal very well.
