[0002] With the rapid development of modern industry, the demand for cleaning agents in the manufacturing, processing and maintenance of metal parts is increasing. Although traditional metal cleaning agents have shown certain effects in cleaning oil stains and removing rust, they still have many deficiencies and shortcomings in terms of cycle stability, durability of anti-rust effect and scope of application, and it is difficult to meet the current requirements of high efficiency and environmental protection. For example, cleaning agents after multiple cycles often have problems such as component separation, precipitation or performance degradation, resulting in a shortened effective service life; the protective film formed by the corrosion inhibitor is not dense enough and is easily ineffective under the influence of the external environment (such as humidity and temperature changes), and cannot provide lasting anti-rust protection for the metal surface; the formula design fails to fully consider the characteristics of various metal materials, resulting in uneven effects of cleaning agents on different metal surfaces.

[0025] Directions: The metal workpiece was immersed in the cleaning agent prepared above, and was soaked and cleaned for 10 minutes at room temperature, with a magnetic field of 75 mT applied.

After cleaning, the metal surface was smooth and had excellent anti-rust effect, especially suitable for pH-sensitive metal materials. Example 4

[0026] This example is used to evaluate the performance of the cleaning agent after regeneration treatment.

[0027] The initial cleaning agent composition and proportion (parts by weight) are as follows: Lauryl alcohol polyoxyethylene ether (LAEO): 20 parts Cetyl alcohol polyoxyethylene ether (CEAO): 10 parts Benzotriazole (BTA): 4.5 parts Imidazolinyl compounds: 2.5 parts Ethylenediaminetetraacetic acid (EDTA): 7.5 parts Sodium carbonate: 3.5 parts Disodium hydrogen phosphate: 2.5 parts Hydroxyethyl cellulose (HEC): 8 parts Nano titanium dioxide (TiO2, average particle size 20-40nm): 1.5 parts γ-Aminopropyltriethoxysilane (APTES): 0.75 parts Polyether modified silicone oil: 0.75 parts Coconut oil fatty acid diethanolamide: 1.5 parts Isopropyl alcohol: 10 parts Water: 40 parts Regeneration process steps: Larger solid particles and suspended matter are separated from the spent cleaning liquid using a centrifuge or sedimentation method.

[0028] The excess water is removed by an evaporator to obtain a concentrated cleaning agent mother liquor.

[0029] According to the analysis results, fresh surfactants (5 parts of LAEO, 2 parts of CEAO), corrosion inhibitors (0.5 parts of BTA, 0.5 parts of imidazoline compounds), and pH adjusters (0.5 parts of sodium carbonate, 0.5 parts of disodium hydrogen phosphate) were added to the concentrated mother liquor in appropriate amounts.

[0030] Re-mix the new cleaning solution according to the proportion and set aside for later use.

[0031] Directions: The metal workpiece was immersed in the regenerated cleaning agent and cleaned at room temperature for 10 minutes. A magnetic field with a field strength of 75mT was applied. The average surface temperature of the metal workpiece was 32°C during the cleaning process. After cleaning, the metal surface was smooth and the anti-rust effect was equivalent to that of the original cleaning agent, proving that the regeneration treatment effectively restored the performance of the cleaning agent. Example 5

[0032] In order to enhance the cyclic stability of the recyclable anti-rust metal cleaning agent, in addition to adding TiO2, high-efficiency dispersants and antioxidants can also be added for optimization. High-efficiency dispersants can be sodium polyacrylate (PAA) or sodium polymethacrylate. Through electrostatic repulsion and steric hindrance effects, nanoparticles and suspended matter can be stably distributed in the solution to avoid re-aggregation of solid particles during regeneration, thereby maintaining the average distribution and fluidity of the cleaning agent; antioxidants can be butylated hydroxyanisole (BHA), α-tocopherol or butylated hydroxytoluene, which can capture free radicals to prevent oxidation reactions, thereby increasing the number of recycling times of the cleaning agent.

[0033] Specifically, sodium polymethacrylate and butylated hydroxytoluene are added here, and the ingredients and proportions (parts by weight) are as follows: Lauryl alcohol polyoxyethylene ether (LAEO): 20 parts Cetyl alcohol polyoxyethylene ether (CEAO): 10 parts Benzotriazole (BTA): 4.5 parts Imidazolinyl compounds: 2.5 parts Ethylenediaminetetraacetic acid (EDTA): 7.5 parts Sodium carbonate: 3.5 parts Disodium hydrogen phosphate: 2.5 parts Hydroxyethyl cellulose (HEC): 8 parts Nano titanium dioxide (TiO2, average particle size 20-40nm): 1.5 parts γ-Aminopropyltriethoxysilane (APTES): 0.75 parts Polyether modified silicone oil: 0.75 parts Coconut oil fatty acid diethanolamide: 1.5 parts Isopropyl alcohol: 10 parts Water: 40 parts Sodium polymethacrylate: 0.5 parts Butylated hydroxytoluene: 0.25 parts The preparation method and the use method are the same as those in Example 1. After testing, it is found that the formula still maintains a high cleaning power and anti-rust effect after multiple cycles, showing excellent cycle stability.

[0034] Performance Testing: The metal workpieces cleaned in the above embodiment were subjected to surface testing, and the test results are shown in the following table: Test items Example 1 Example 2 Example 3 Example 4 Example 5 Cleaning time (min) 10 10 10 10 10 Cleaning temperature (℃) 32 30 31 32 31 Surface finish excellent excellent excellent excellent excellent Anti-rust effect good Significant improvement Excellent Equivalent to original cleaning agent Excellent Are there any scratches? none none none none none Working principle: The surfactant in the cleaning agent can significantly reduce the surface tension of water, allowing the cleaning agent to penetrate into the tiny gaps on the metal surface, emulsifying and dispersing oil and grease pollutants. At the same time, the complexing agent combines with the metal ions to prevent scale formation and ensure the clarity and stability of the cleaning agent. The corrosion inhibitor in the cleaning agent can quickly adsorb on the metal surface to form a dense and stable protective film, which effectively prevents oxygen and moisture from contacting the metal surface, thereby preventing oxidation and rust. The organic silane coupling agent gives the product self-repairing properties. When the protective film is damaged due to wear or other reasons, it can automatically repair the damaged area and extend the anti-rust effect. This dual anti-rust mechanism ensures that the metal surface after cleaning remains smooth and rust-free for a long time. In order to achieve multiple recycling of the cleaning agent, a high-efficiency dispersant is introduced to prevent the re-aggregation of nanoparticles and other suspended matter, and an antioxidant is added to delay the aging process of the organic components in the cleaning agent and extend its service life.
