Description
The technical field is as follows:
the invention belongs to the technical field of aluminum alloy processing, and particularly relates to an aluminum alloy cutting fluid and a preparation method thereof.
Background art:
the aluminum alloy has low density, high strength similar to or superior to that of high-quality steel, good plasticity, excellent electric conductivity, heat conductivity and corrosion resistance, is the most extensive non-ferrous metal material in industrial application, and has been widely applied to aviation, aerospace, automobile, mechanical manufacturing, ships and chemical industry. The aluminum alloy cutting is an essential working procedure in the processing process, and plays an irreplaceable role in the development process of the aluminum alloy industry.
Problems that easily occur in the aluminum alloy cutting process:
1. the chemical property of aluminum is relatively active, and the aluminum is easy to oxidize in the air and can react in an acidic environment and an alkaline environment.
2. The aluminum alloy has a large coefficient of thermal expansion, and cutting heat can be rapidly spread to an aluminum workpiece, so that the workpiece is easily subjected to thermal deformation, the size of the workpiece is difficult to control, and the processing precision is reduced.
3. The aluminum alloy is soft in quality and large in plasticity, the cutter is easy to adhere during cutting, accumulated scraps are formed on the cutter, and fusion welding phenomenon is more likely to occur on the cutter edge during high-speed cutting, so that the cutter loses cutting capability, and the processing precision and the surface roughness are influenced.
4. Aluminum has a high degree of ductility and may form long, streak-like cracks that block the cutting zone, making the cutting process difficult, while the cut chips are difficult to remove by the cutting fluid.
5. The main corrosion forms of the aluminum alloy are surface discoloration and pitting corrosion, the surface discoloration is changed from brown to black, and the pitting corrosion is small and deep corrosion, but sometimes the pitting corrosion is communicated with each other to form large holes, and white powder is separated out, which is commonly called white rust.
At present, the aluminum alloy cutting fluid has two forms, one is oily cutting fluid, the other is aqueous cutting fluid, the two cutting fluids have respective advantages and disadvantages,
the oily cutting fluid has the advantages of good lubricity, capability of forming an oil film on an aluminum alloy cutting surface, poor thermal conductivity, easiness in deterioration and certain ignition point; for example, the national invention patent with the patent number of 201410362160.0 discloses a special cutting fluid for aluminum alloy, 10-15 parts of sodium dodecyl sulfate, 1-4 parts of emulsified silicone oil, 9-15 parts of petroleum sodium sulfonate, 3-7 parts of dodecenylsuccinic acid, 1.5-3 parts of benzotriazole, 8-13 parts of emulsifier, 1.2-2.6 parts of extreme pressure additive and the balance of mechanical oil, the method is an oily cutting fluid, the emulsifier and the defoamer need to be added, and a large amount of bubbles can be generated in the using process to influence the observation;
the water-based cutting fluid has the advantages of good fluid performance, good heat conductivity and poor lubricity. The national invention patent with the patent number of 105001966B discloses an aluminum and aluminum alloy cutting fluid, the cutting fluid has no foam in the using process, is a fully-synthetic water-based cutting fluid, can conveniently observe and monitor a workpiece in the processing process of the workpiece by using the cutting fluid, and introduces a large amount of polyglycerol in order to solve the problem of poor lubricating property of the water-based cutting fluid, thereby inevitably causing the reduction of fluid performance.
In the actual use process of the cutting fluid, two morphological structures exist, namely a part which is in direct contact with metal and a milling cutter and has high temperature and needs good lubricating property and protective property, and a part which is not in contact with the metal and the milling cutter and has low temperature and needs good heat conductivity and observation.
That is, the aqueous cutting fluid has excellent thermal conductivity, and particularly for aluminum alloys, the aqueous cutting fluid is soft, has high plasticity, is easy to stick to a cutter during cutting, forms built-up edges on the cutter, is more likely to generate a fusion welding phenomenon on a blade during high-speed cutting, causes the cutter to lose cutting capability, affects the processing precision and surface roughness, has high ductility of aluminum materials, is likely to form long strip-shaped cracks, and can block a cutting area, so that the problem that the cutting process is difficult to solve is difficult;
the oily cutting fluid can well solve the problems, but has poor thermal conductivity, easy contamination with bacteria, easy foaming, inconvenient observation and certain danger in ignition point production.
At present, no good cutting fluid can meet the actual requirements of two morphological structures in the actual use process.
The invention content is as follows:
in order to solve the problems and overcome the defects of the prior art, the invention provides the aluminum alloy cutting fluid which can effectively solve the problem that no good cutting fluid can meet the actual requirements of two morphological structures in the actual use process.
The specific technical scheme for solving the technical problems comprises the following steps: the aluminum alloy cutting fluid is characterized by comprising the following components in parts by mass: 6-8 parts of polyglycerol, 0.5-1 part of sodium citrate, 3-8 parts of straight and long carbon chain dibasic acid sodium salt, 0.1-0.6 part of benzotriazole, 7-10 parts of triethanolamine, 1-3 parts of thiourea, 1-4 parts of sodium lactate and 10-25 parts of deionized water.

Further, the sodium salt of the straight-long-carbon-chain dibasic acid comprises one or a mixture of more than two of sodium sebacate, sodium undecanedioate and sodium dodecanedioate.
Further, the regulator is organic ammonium salt.
Further, the organic ammonium salt is ammonium acetate.
Further, the preparation method of the aluminum alloy cutting fluid is characterized by weighing 6-8 parts by mass of polyglycerol, 0.5-1 part by mass of sodium citrate, 3-8 parts by mass of straight long carbon chain dibasic acid sodium salt, 0.1-0.6 part by mass of benzotriazole, 7-10 parts by mass of triethanolamine, 1-3 parts by mass of thiourea, 1-4 parts by mass of sodium lactate, 2-4 parts by mass of polyether polyol and 1-2 parts by mass of ammonium acetate, dissolving the above materials in deionized water, adjusting the mass part of the deionized water to 10-25 parts by mass, adjusting the pH to 8.0-9.6, and preparing a cutting fluid mother solution, wherein the cutting fluid mother solution is diluted to 2-10 times by using the deionized water when in use.
The invention has the beneficial effects that:
according to the invention, polyether glycol is creatively introduced into the water-based cutting fluid, and the cloud point temperature of the cutting fluid is raised to be higher than the non-operation area temperature of the aluminum alloy cutting fluid and lower than the operation surface temperature of the aluminum alloy cutting fluid by adding ammonium acetate, so that the recycled cutting fluid can be ensured to keep a clear fluid state of the water-based cutting fluid at a low temperature of 60 ℃, heat transfer is easy to observe, and the emulsion can be generated at a high temperature of more than 90 ℃, so that the lubricating and protecting effects can be well realized;
therefore, the requirements of two morphological structures of the water-based aluminum alloy cutting fluid in the actual use process are met, namely, the part which is directly contacted with metal and a milling cutter is high in cutting fluid temperature and needs good lubricating property and protective property, and the other part which is not contacted with the metal and the milling cutter is low in temperature and needs good heat conductivity and observation requirements.
