Description
Technical Field
The invention belongs to the technical field of grinding fluid cleaning, and relates to a cleaning agent for removing silicon dioxide grinding fluid on the surface of 6-series aluminum alloy.
Background
With the continuous updating and iteration of electronic consumer goods, the requirements on the material of metal shells of electronic products such as smart watches, mobile phones, tablet computers and the like are higher and higher, and 6-series aluminum alloy has the advantages of good processing performance, convenience in machining, high strength, small density and light weight, and is very suitable for protecting shells of electronic consumer goods and shells of components. For the finish machining of 6 series aluminum surfaces, the surface polishing is often carried out by using silicon dioxide, aluminum oxide and diamond grinding fluid, wherein the silicon dioxide polishing fluid is widely used for the fine polishing of metal surfaces due to small particle size, high stability and uniform and bright polishing surface. However, the silicon dioxide polishing solution is easy to crosslink and gel after dehydration, so that a silicon oxide film is easy to remain on the surface of the 6-series aluminum alloy polished by the silicon dioxide polishing solution, and if the silicon oxide film is not cleaned in time, the subsequent aluminum alloy surface treatment process such as anodic oxidation is influenced.
The existing cleaning method of the silicon dioxide grinding fluid on the surface of the aluminum alloy mainly adopts a silicon dioxide polishing fluid cleaning agent and an ultrasonic cleaning process to clean. The existing cleaning agent is generally divided into weak acid, strong acid and alkaline according to the acidity and alkalinity, if the weak acid cleaning agent is adopted for cleaning, the problem of insufficient cleaning force exists, the nano-scale silicon dioxide grinding fluid remained on the surface cannot be cleaned, and the surface of the 6-series aluminum alloy is soaked with water or the cleaning agent remains after the 6-series aluminum alloy is cleaned and dried due to the fact that the temperature of the cleaning tank is too high and the chemical bonds of the active components are broken and decomposed; if an alkaline cleaning agent is used for cleaning, corrosion will occur on the surface of the 6-series aluminum alloy, and if a strong acid cleaning agent is used, pitting corrosion or mottling will occur after the 6-series aluminum alloy is cleaned and dried.
Disclosure of Invention
In order to solve the above problems, the primary object of the present invention is to provide a cleaning agent for removing silica polishing slurry on the surface of 6-series aluminum alloy, which has excellent cleaning effect.
Another object of the present invention is to provide a cleaning agent for removing silica polishing slurry on the surface of 6-series aluminum alloy, which does not corrode the surface of the aluminum alloy and is easy to drift after cleaning.
In order to achieve the purpose, the technical scheme of the invention is as follows:
the invention provides a cleaning agent for removing silicon dioxide grinding fluid on the surface of 6-series aluminum alloy, which comprises the following components in percentage by weight:
3 to 15 percent of organic acid,
15 to 30 percent of surfactant,
1 to 20 percent of wetting agent,
1 to 13 percent of corrosion inhibitor,
10 to 30 percent of auxiliary agent,
the balance of water.
Further, the organic acid is one or more of citric acid, oxalic acid, methanesulfonic acid, phytic acid, tartaric acid, fumaric acid, hydroxyethylidene diphosphonic acid, lactic acid and polyacrylic acid.
Furthermore, the surfactant is prepared by compounding an anionic surfactant and a nonionic surfactant. The anionic surfactant comprises alkyl ether carboxylate, alkylbenzene sulfonate, alkyl sulfonate and alkyl sulfate. The nonionic surfactant comprises polyoxyethylene sorbitan fatty acid ester, fatty amine polyoxyethylene compound, alkyl glycoside and fatty alcohol polyoxyethylene ether.
Further, the wetting agent is one or a mixture of more of dipropylene glycol methyl ether, dipropylene glycol butyl ether, diethylene glycol butyl ether, benzyl alcohol, propylene glycol phenyl ether, propylene carbonate, glycerol and polyethylene glycol.
Further, the corrosion inhibitor is one or a mixture of more of sodium tungstate, sodium molybdate, benzotriazole, tolyltriazole, thiourea, hexamethylenetetramine and oleic imidazoline.
Further, the auxiliary agent is one or a mixture of more of sodium citrate, sodium gluconate, sodium tripolyphosphate, maleic anhydride-acrylic acid copolymer, sodium phytate, disodium ethylene diamine tetraacetate, disodium hydroxyethylidene diphosphonate, 2-phosphate-1, 2, 4-tricarboxylic acid butane, sodium diethylenetriamine pentamethylene phosphonate and sodium nitrilotrimethylene triphosphonate.
Further, the preparation method comprises the following steps: firstly, adding water into stirring equipment, starting stirring, sequentially adding an auxiliary agent, a corrosion inhibitor, a wetting agent and organic acid, and finally adding a surfactant; adding new materials every time, ensuring that the materials added in the previous batch are uniformly mixed with water and completely dissolved in the water, and slowly adding the powder raw materials into stirring equipment in batches; the stirring temperature is 25-35 ℃, and the stirring speed is 70-100 rpm. The stirring time is long before the batch of the feed materials are completely dissolved in the water.
Further, the action mechanism of the invention is as follows: in the invention, the surfactant is prepared by compounding an anionic surfactant and a nonionic surfactant, wherein the anionic surfactant mainly comprises alkyl sulfonate ions and alkyl sulfate ions which are hydrophilic groups, can generate physical adsorption with aluminum elements on the surface of the aluminum alloy and gradually permeate into a silicon dioxide film or a stain interlayer on the surface of the metal, so that the physical adsorption action force of a silicon dioxide molecular film and the surface of the aluminum metal is weakened; the small molecular wetting agent such as ethers and alcohols can accelerate the permeability of the surfactant and water, assist the ultrasonic cleaning process, can generate strong water wave vibration cavitation, and enhance the dispersion effect of the cleaning agent on the silicon dioxide film; the auxiliary agent such as hydroxyethylidene diphosphonic acid, maleic anhydride-acrylic acid copolymer and the like has strong chelating and dispersing capacity in molecules, can effectively adsorb silicon dioxide particles, calcium and magnesium ions and blocky impurities, and can strip stains such as silicon dioxide films on the surfaces of 6 series aluminum alloys; the surfactant, the wetting agent, the ultrasonic process and the auxiliary agent can generate synergistic effect to perform wetting, permeating, stripping and emulsifying effects on the silicon dioxide film on the surface of the 6-series aluminum alloy. In the present invention, the 6-series aluminum alloy contains a small amount of two elements of magnesium and silicon in addition to the main element of aluminum, and aluminum is a special amphoteric metal, and is capable of reacting with an acid or an alkali, and particularly, when the cleaning solution pH is greater than 7, the 6-series aluminum alloy is susceptible to corrosion and blackening and discoloration of the surface, so that it is preferable to clean stains on the surface of the 6-series aluminum alloy with an acidic cleaning agent. Organic weak acid such as sulfonic acid, phytic acid, hydroxyethylidene diphosphonic acid and the like is selected, so that the acidity of a cleaning agent system can be kept, the weak acidity can ionize hydrogen ions, and the corrosion to the surface of the 6-series aluminum alloy can be reduced to the greatest extent. The corrosion inhibitor sodium tungstate or sodium molybdate can form a layer of water-insoluble aluminum salt passivation film on the surface of the aluminum alloy, so that the corrosion substances such as acid and alkali can be isolated, the corrosion rate is reduced, and the nitrogen element in the benzotriazole and hexamethylenetetramine compound can form a complex with the surface of the aluminum alloy, and the complex covers the surface of the aluminum alloy in a chemical adsorption manner so as to isolate the acid and alkali corrosion substances. The corrosion inhibitor is matched with organic weak acid, so that the problem of corrosion of an acidic cleaning agent system to the surface of the aluminum alloy is effectively reduced, and a satisfactory corrosion inhibition effect can be achieved.
The invention has the beneficial effects that: compared with the prior art, the organic acid and the corrosion inhibitor adopted by the invention hardly corrode a polished highlight surface of the 6-series aluminum material, the polished highlight surface base material can be maximally reduced, due to the use of the wetting agent and the composite surfactant, the hydrophilicity of the surface of the cleaned base material is enhanced, the rinsing is easy, the surface is free from residue after drying, and the residual silicon dioxide grinding fluid component on the surface of the 6-series aluminum material can be simply and efficiently removed by matching with an ultrasonic cleaning process.
