Environment-friendly aluminum and aluminum alloy corrosion cleaning agent and preparation method thereof

The invention relates to the technical field of industrial cleaning agents, in particular to an environment-friendly aluminum and aluminum alloy corrosion cleaning agent and a preparation method thereof. Comprising the following raw materials in parts by weight: 7-20% of a nonionic surfactant, 15-20% of inorganic acid, 5-10% of organic acid, 1-2% of a corrosion inhibitor, 2-3% of a solubilizer, 0.2-0.5% of a spreading agent, 0.2-0.5% of a defoaming agent and the balance of water. The preparation method comprises the following steps: S1, adding part of water into a blending kettle, heating to 50 DEG C, adding the nonionic surfactant, and stirring for 30 minutes; s2, opening a bin door of the blending kettle, adding the raw materials in batches according to the weight percentage, and stirring for 60 minutes; s3, closing the blending kettle, and standing for 1 hour; and S4, sampling and detecting, and canning after no error is detected. The problem that existing aluminum and aluminum alloy are corroded is mainly
