Description
Technical field
The present invention relates to aluminium alloy waterborne cleaning agent, and in particular to a kind of waterborne cleaning agent of environmental protection.
Background technology
Aluminium alloy is most widely used class nonferrous materials in industry, aluminium alloy is stretched, rolling, punching press etc.
After processing, aluminium material surface can usually leave some lubrication greasy dirts, if thoroughly do not removed to lubricating greasy dirt, process in subsequent anneal
Cheng Zhong, it may occur that serious brown oil class, affects product appearance, causes user to return goods.
Traditional deoiling method has high-temperature alkali forensic chemistry to go oil process and organic solvent to remove oil process.High-temperature alkali forensic chemistry removes oil process
With effect of deoiling is good, low cost and other advantages, but more serious is corroded to aluminum alloy surface;And organic solvent goes oil process although to deoil
Effect is good, but there are problems that organic solvent volatilization pollution environment, and clean after aluminium alloy corrosion resistance it is poor.
At present, most of aluminium alloy is cleaned mainly with aqueous surface cleaning agent come the greasy dirt on cleaning workpiece surface, can be fast
Speed removes the dirts such as the greasy dirt of aluminium and its alloy surface, dust, hand perspiration, organic matter, inorganic salts, patent CN101311316A " gold
Category aluminum cleaning agent " can effectively remove the greasy dirt on Al alloy parts surface, but the casting workpiece jaundice after cleaning, and have a strong impact on
The outward appearance of workpiece.Patent CN101962779A " removing the acidic cleaner of aluminium material surface oxide skin and oiliness carbon distribution mixed layer " can
The oxide-film and oiliness carbon distribution on casting workpiece surface are effectively removed, but scavenging period is long and easily generates in surface of the work white
Spot, while both aluminum alloy cleaning agents all contain more antioxidant, processes the residual after aluminum alloy surface and has environment dirty
Metachromia.
The content of the invention
The invention aims to solve defect present in prior art, there is provided one kind can effectively remove aluminium alloy table
Face greasy dirt and oxide-film, the cleaning agent of environmental protection.
In order to achieve the above object, the invention provides a kind of aluminium alloy aqueous, environmental protective cleaning agent, cleaning agent includes following
The component of weight percentage：Surfactant 9-15%, organic base 15-25%, composite corrosion inhibitor 0.5-1%, defoamer 0.1-
0.3%, water 60-75%；Wherein, composite corrosion inhibitor is made up of ammonium molybdate, sodium metasilicate and cerous acetate, ammonium molybdate, sodium metasilicate and acetic acid
Cerium preferred mass ratio is 1：（2.5-3）：（0.5-1）, optimum proportioning is 1:2.5:0.5.

Present invention also offers the preparation method of above-mentioned cleaning agent, by above-mentioned all components（Surfactant, organic base,
Composite corrosion inhibitor, defoamer and water）Mixed dissolution is uniform.Products obtained therefrom be translucent milky white liquid, density (g/cm3)
(proportion) is 1.25 ± 0.03.
The present invention has advantages below compared to existing technology：
1st, the present invention can effectively suppress the diffusion of aluminum alloy surface oxygen and the confession of aluminium alloy electronics using composite corrosion inhibitor
Give, fully suppress surface cathode reaction and anode reaction, and rare earth compound therein forms rare-earth oxidation in aluminum alloy surface
Thing film, replaces natural oxide film, prevents aluminum alloy surface reaction.
2nd, the cleaning agent prepared using the formula of the present invention can effectively remove greasy dirt and the oxidation on Al alloy parts surface
Film, aluminum alloy surface are fair and clear.
3rd, the present invention has the spies such as moment penetrating power, superpower emulsifying capacity, good increase-volume performance, excellent washing
Property, and the biological degradation rate of component materials is above 95% used in inventive formulation, at the same not phosphorus element-containing, nitrate,
Lead, mercury etc., can effectively alleviate the processing pressure and processing cost of waste water.
4th, compared with prior art, the present invention greatly improve the cleaning efficiency of aluminium and the another part of alloy, realize it is high-accuracy
Wash, clean and be passivated under same process conditions while complete, simplify conventional treatment process, cleaning cost is significantly reduced, real
Innoxious environment-friendly type cleaning is showed.
