Embodiment 1
[0033] A water-based metal cleaning agent, the mass percent of each component is: sodium dodecylbenzene sulfonate 1.8%, SIMULSOL OX1309L 8.5%, RHODOCLEAN MSC 1.5%, Rhodafac H66 2.5%, corrosion inhibitor (molybdenum Sodium Acetate 4.5%, PE1198LA 0.25%), Disodium EDTA 2.0%, Triethanolamine 28.75%, C740 water-based defoamer 0.82%, distilled water surplus, the specific preparation steps are as follows:
[0034] Weigh each raw material according to the above ratio, add anionic surfactant, nonionic surfactant Ⅰ (SIMULSOL OX1309L), nonionic surfactant Ⅱ (RHODOCLEAN MSC) and nonionic surfactant Ⅲ (Rhodafac H66) in sequence, and then Add corrosion inhibitor, ethylenediaminetetraacetic acid disodium salt (auxiliary), triethanolamine (organic base) and distilled water, and finally add defoamer (based on a total of 100g), and stir at room temperature for 30 minutes until the solution is clear and transparent. The water-based metal cleaning agent.
[0035]The water-based metal cleaning ag...
Embodiment 2
[0037] A water-based metal cleaning agent, the mass percentage of each component is: alkyl alkoxy ether fatty acid potassium 1.5%, SIMULSOL OX1309L 2.5%, fatty alcohol EO-PO block copolymer 5.5%, Rhodafac H662.0 %, sodium molybdate 4.5%, PE1198 LA 0.25%, disodium edetate 1.75%, triethanolamine 27.5%, C740 water-based defoamer 0.52%, distilled water surplus, its preparation method is the same as embodiment 1.
[0038] The water-based metal cleaning agent prepared in this example was tested for degreasing rate, foam performance, anti-rust performance and anti-corrosion performance, and the results are shown in Table 1.
Embodiment 3
[0040] A water-based metal cleaning agent, the mass percentage of each component is: sodium dodecylbenzene sulfonate 1.8%, SIMULSOL OX1309L 1.0%, ethylenediamine EO-PO block copolymer surfactant 7.8% , RhodafacH66 2.5%, sodium molybdate 4.5%, PE1198 LA 0.375%, EDTA disodium 2.125%, triethanolamine 30.25%, C740 water-based defoamer 0.56%, distilled water surplus, its preparation method is the same as embodiment 1.
[0041] The water-based metal cleaning agent prepared in this example was tested for degreasing rate, foam performance, anti-rust performance and anti-corrosion performance, and the results are shown in Table 1.
[0042] Table 1
[0043]
