The application discloses an aluminum
alloy cleaning agent and a preparation method and application thereof, and belongs to the technical field of cleaning agents. The aluminum
alloy cleaning agent comprises the following raw materials in parts by weight: 7-12 parts of ionic surfactant A, 3.5-6 parts of non-ionic surfactant B, 0.2-3 parts of a dispersing solubilizing agent, 0.8-1.5 parts of a penetrating agent, 3-6 parts of a chelating agent, 0.2-2 parts of an inhibitor, 0.01-0.05 parts of a defoaming agent and 67-83 parts of deionized water. The non-ionic surfactant A comprises at least one of a
fatty alcohol polyoxyethylene ether and a
nonylphenol polyoxyethylene ether. The non-ionic surfactant B comprises a
sorbitan fatty acid ester. The dispersing solubilizing agent comprises a polyhydric
alcohol. The aluminum
alloy cleaning agent can effectively improve cleaning power, avoid aluminum alloy tarnishing, and is
environmentally friendly. The application further provides a preparation method and application of the aluminum alloy cleaning agent.
