Problems solved by technology

[0002] After various processing of aluminum alloy, some lubricating oil stains are often left on the surface of the aluminum material. If the oil stains are not completely removed, serious brown oil spots will appear in the later processing, which will seriously affect the appearance of the product.
At present, cleaning agents for aluminum alloys at home and abroad generally use solvent cleaning or strong acid and strong alkali cleaning, which will cause some problems such as environmental pollution and corrosion of parts. Under the requirements of modern industry, higher requirements are put forward for aluminum alloy cleaning agents. Therefore, need a kind of aluminum alloy water-based cleaning agent to change the above-mentioned problem

Abstract

The invention discloses a water-based detergent for an aluminum alloy. The detergent comprises the following components in percentages by weight: 1-30% of a surfactant, 1-20% of polybasic carboxylic acid, 5-10% of oleamide, 0.5-5% of polyhydroxyacetate, 1-5% of carbonate, 0.05-0.1% of sodium hydroxide, 1-15% of alcohols and deionized water, totaling 100%. The water-based detergent can effectively remove greasy dirt and oxidation films on the surface of the aluminum alloy, so that the surface quality of the aluminum alloy is good.
