Abstract

The invention discloses a water-based cleaning agent for an aluminum alloy part. The cleaning agent comprises components in percentage by weight as follows: 2%-10% of AEC (alcohol ether carboxylate), 2%-10% of poly-carboxylate, 5%-20% of an alcohol ether surfactant, 5%-10% of oleamide, 1%-2.5% of diethanol amine, 1%-2.5% of triethanolamine, 0.5%-2% of benzoate, 0.5%-4% of hydroxyacetic acid salt, 1.5%-4% of carbonate, 0.5%-3% of borax, 0.1%-0.6% of sodium hydroxide, 2%-10% of alcohol and the balance of deionized water. The water-based cleaning agent can guarantee the machining precision of an aluminum alloy and is environment-friendly, fast, safe, non-ignitable, non-explosive, simple to operate, low in cost, non-toxic, free from harm to a human body, convenient and safe to use and energy-saving, the cleaning speed is high, the surface quality is good, and a cleaned aluminum alloy can be electroplated later.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a water-based cleaning agent for aluminum alloy parts. Background technique [0002] At present, cleaning agents for aluminum alloys at home and abroad generally use solvent cleaning, strong acid and strong alkali cleaning, etc. Solvent cleaning mainly utilizes solvent-based cleaning agents for steam cleaning or immersion cleaning with appropriate equipment. Since solvent-based cleaning agents are not only expensive and have the disadvantages of being flammable and damaging to the skin, but also environmental pollutants, high-cost methods and special devices are required to prevent steam leakage and to recover and dispose of used solvents. Strong acid and strong alkali cleaning is to use the strong chemical action of strong acid (such as concentrated acetic acid, concentrated nitric acid, concentrated phosphoric acid) or strong alkali (such as potassium hydroxide, sodium hydroxide, etc.) to r...
