Abstract

The invention discloses an environment-friendly aluminum cleaning agent and a preparation method thereof. The cleaning agent is composed of the following components in percentage by weight: 20% to 25% of inorganic acid, 10% to 20% of organic acid, 10% to 18% of surfactant, 8% to 15% of osmotic agent, 6% to 18% of emulsifier, 2% to 8% of antifoaming agent, 5% to 8% of complexing agent, and 25% to 30% of water. In the provided cleaning agent, the using amount of hydrochloric acid, sulfuric acid, and nitric acid is reduced, the aluminum parts are washed by medium-strong acids and organic acids, and the cleaning agent has a very good oil stain and rust removing ability. The cleaning agent is acidic, the pH value of the cleaning agent is 2.1 to 5.6, and the cleaning agent can well remove the oxide scale on the aluminum surface. Because the acidity of the organic acids is weak, the over-corrosion on work tools and acid volatilization, which can harm the workers' health, are effectively avoided, and the cleaning effect is not influenced at the same time. Moreover the adopted organic acids are easy to decompose, and thus the cleaning agent is environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of aluminum material cleaning, and in particular relates to an environment-friendly aluminum material cleaning agent, and also relates to a preparation method of an environment-friendly aluminum material cleaning agent. Background technique [0002] Aluminum alloy has been widely used in material engineering due to its advantages such as low density, high specific strength, good thermal conductivity, and easy forming and processing. During the use of aluminum alloys, different use environments such as alkaline, acidic, neutral solutions, and marine environments can cause corrosion of aluminum alloys; and commonly used anti-corrosion treatment methods include surface spray paint, powder coating, and anodic oxidation. and micro-arc oxidation. Before realizing the above-mentioned anti-corrosion treatment and coating the film layer, the surface of the aluminum part must be cleaned. The quality of the cleaning d...
