Abstract

The invention relates to a special metal cleaning agent for a water-based reactive aluminum product. The special metal cleaning agent is prepared from a surfactant, a solvent, plant oleic acid, triethanolamine, organosiloxane, a corrosion inhibitor, alkyl phosphate, a defoamer 575, a preservative 1227, deionized water and the like. The metal cleaning agent disclosed by the invention is non-toxic, harmless and pollution-free, is harmless to human, is corrosion-free to the surface of the aluminum product, is odorless during long-time use, does not deteriorate, has extremely excellent cleaning and antirusting functions, particularly cleans thick and hard deposited carbon and stubborn stains thoroughly, does not corrode aluminum products of various models and is applicable to ultrasonic machine cleaning, spraying machine cleaning, handed soak rinsing and the like, and the natural antirusting time of workpieces is over 60 days after cleaning.

Description

Technical field [0001] The invention belongs to the field of metal cleaning agents, and in particular relates to a metal cleaning agent special for water-based reactive aluminum materials and a preparation method thereof. Background technique [0002] Metal cleaning agents widely used in metal cleaning in my country are mainly various solvents, alkaline or acidic water-based cleaning agents. Solvent-based cleaners degrease quickly, have good low-temperature washing effects, have low metal corrosion, but are toxic and harmful, pollute the environment, and have high costs; water-based non-phosphorus cleaners are non-toxic, odorless, safe and environmentally friendly, and low-cost, but difficult to remove metal surfaces In order to improve the detergency, it is often necessary to heat the cleaning agent. The heated cleaning agent corrodes metals, especially aluminum products, and easily discolors aluminum products. At present, the increasingly prominent environmental pollution issu...
