Aluminum alloy surface treatment agent

Abstract

The invention discloses an aluminum alloy surface treatment agent. The treatment agent is composed of the following components in parts by mass: 10-20 parts of sodium hydroxide, 5-10 parts of deionized water, dodecylbenzenesulfonic acid 10-20 parts of sodium, 2-5 parts of sodium carbonate water, 2-5 parts of silicone oil, 5-10 parts of cocamidopropyl betaine, 5-10 parts of glycerol boric acid fatty acid ester, tetrabasic zinc chromate 5‑10 parts, 5‑10 parts of diatomaceous earth, 1‑3 parts of dispersant, 5‑10 parts of reduced glutathione, 2‑5 parts of organic acid, 1‑3 parts of sodium laureth sulfate , 1‑3 parts of stabilizer, and the balance of water. The invention is beneficial in that it can remove rust and increase luster of aluminum alloy, has strong cleaning power, simple production process, low cost, stable and reliable quality, wide application range, good adsorption, lubricity, and corrosion resistance. And no damage to the surface of aluminum products.

Description

technical field [0001] The invention relates to the field of metal treatment agents, in particular to an aluminum alloy surface treatment agent. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. The existing methods for treating metal surfaces not only have complex procedures, high labor intensity (especially for the treatment of rusted metal components), low efficiency, but also pollute the environment, but this type of detergent is difficult to remove heavy oil, and its The oil removal ability is poor, so it is difficult to meet the process requirements of cleanliness. Contents of the invention [0003] The object of the present invention is to provide a kind of aluminum alloy surface treatment agent, described treatment agent is made up of the following components by mass parts: 1...
