Background
The dirt and processing residues on the processed surface of the metal workpiece, such as various acids, alkalis, salts, dust, abrasives, polishing paste, cutting fluid, hand sweat, various grease and the like, are water-soluble and water-insoluble, and if the dirt and the processing residues are not cleaned, the dirt and the processing residues not only affect the smooth operation of the processing procedure, but also cause and accelerate the corrosion of the surface of the aluminum material, and affect the quality and the service life of the product. The selection of the cleaning process and the quality of the cleaning work quality not only relate to the major problems of energy, safety, environmental protection and the like, but also directly influence the performance and the quality of the product, so the oil removal cleaning process becomes an indispensable important link in the modern industrial production.
The quality of the oil removal treatment before the surface oxidation of the aluminum alloy directly affects the quality of the coating, and the oil removal agent sold in the market at present requires high cleaning temperature, poor corrosion resistance and rust resistance, high price and poor oil removal effect, and often uses environment-friendly poor substances containing fluorine, hexavalent chromium and the like. The normal temperature high activity degreasing cleaning agent is degreasing liquid which is prepared by using water as a solvent, using a surfactant as a main component and adding a defoaming agent, an antirust agent or other additives and has the function of cleaning dirt on the surface of an aluminum material. The normal-temperature high-activity degreasing cleaning agent has a series of advantages of energy conservation, no harm to the health of operators, pollution reduction, environmental protection, no toxicity, safety, low cleaning cost and the like, is rapidly developed in China in recent ten years, and can be used for producing various metal cleaning agents by self-research or study on advanced technologies of foreign similar products. But the technical performance indexes such as cleaning rate, defoaming property, rust resistance, stability and the like can not meet the requirements of industrial production, and the production cost is higher, so the method has extremely important significance for the development of the high-activity oil-removing cleaning agent at normal temperature.
Disclosure of Invention

According to the invention, alkylolamide, triethanolamine oleate and a demulsifier are compounded to form a composite surfactant system, wherein the alkylolamide serving as a nonionic surfactant and the triethanolamine oleate serving as an anionic surfactant act synergistically with the demulsifier, so that water-soluble grease and oil-soluble grease on the surface of a workpiece to be degreased and cleaned can be simultaneously destroyed and decomposed, various oil stains on the surface can be efficiently removed through demulsification flocculation precipitation, and the cleaning capability of the degreasing cleaner is greatly improved. According to the invention, oxalic acid and carbonic acid are compounded to serve as an acid etching solution with mild corrosion effect, so that excessive corrosion to aluminum and aluminum alloy can be avoided, and a workpiece with good surface glossiness can be obtained.

As a further improvement of the above, the flocculant is selected from polyaluminium chloride or polyferric sulfate. Particularly, the flocculant has good dispersion performance with other raw material components, and further improves the stability of the oil removal cleaning agent.
As a further improvement of the scheme, the concentration of the oxalic acid is 8-10 g/L, and the concentration of the carbonic acid is 5-10 g/L. Specifically, the concentration of oxalic acid and carbonic acid is limited, so that the oil removing cleaning agent has a good cleaning effect on oil stains on the surfaces of aluminum and aluminum alloy.
As a further improvement of the above scheme, the metal corrosion inhibitor is silicate. Specifically, the metal corrosion inhibitor is a non-toxic raw material, and toxic metal elements are prevented from being introduced, so that the processing environmental protection performance of the oil removal cleaning agent is greatly improved.
The preparation method of the oil removal cleaning agent comprises the following process steps: uniformly mixing oxalic acid, carbonic acid and water at normal temperature, heating to 40 ℃, preserving heat, sequentially adding an imidazoline corrosion inhibitor, a metal corrosion inhibitor, hydrolyzed polymaleic anhydride, alkylolamide, triethanolamine oleate, EDTA and silicone oil, uniformly mixing, performing ultrasonic vibration treatment for 1-3 min, cooling to room temperature, adding a demulsifier and a flocculating agent, and uniformly stirring to obtain a finished product of the oil-removing cleaning agent.
Specifically, the invention effectively improves the dispersibility of each raw material component by limiting the adding sequence of each raw material component and adopting methods of heating mixing, ultrasonic vibration treatment and the like, thereby obtaining a product with good stability and being capable of being stored for a long time.
The invention has the beneficial effects that:
according to the invention, through adjusting the raw material components and the proportion thereof, the oil removal cleaning agent has a quick and efficient oil removal, rust removal and cleaning effect on various oil stains on the surfaces of aluminum and aluminum alloy, is non-toxic, phosphorus-free, free of strong acid and heavy metal ions, environment-friendly and pollution-free, and is suitable for quickly removing various oil stains and rust stains on the surfaces of aluminum and aluminum alloy at one time at normal temperature.
