Air conditioner aluminum foil surface passivation solution

Abstract

The invention discloses an air conditioner aluminum foil surface passivation solution. The passivation solution is prepared from yttrium oxide, GdCl3.6H2O, nanometer bentonite, sodium silicate, inositol hexaphosphate, silica sol, epoxy resin, hydrogen peroxide, deionized water, phospholipid fatty acid, sodium alkyl sulfate and auxiliary agents. The passivation solution is environmentally friendly, safe, wide in raw material source and low in cost; and in the using process of the passivation solution, a bath solution is stable, components are safe and environmentally friendly, and various later-stage reprocessing properties of an air conditioner aluminum foil product are not influenced. A passivation film formed by the air conditioner aluminum foil passivation solution is high in stability and corrosion resistance, good in oxidation resistance and capable of effectively protecting an air conditioner aluminum foil material from external corrosion; the service life of the air conditioner aluminum foil material is effectively prolonged; and the air conditioner aluminum foil surface passivation solution is convenient to use, practical and suitable for being applied and popularized. An air conditioner heat exchanger made of air conditioner aluminum foil treated through the passivation solution is more excellent in performance; and compared with that of a common air conditioner heat exchanger, the service life of the air conditioner heat exchanger is prolonged by one time or above.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an air-conditioning aluminum foil surface passivation solution. Background technique [0002] Aluminum is one of the most abundant metal elements in nature. Aluminum foil is a kind of A hot stamping material that is directly rolled into thin sheets by metal aluminum, and its hot stamping effect is similar to that of pure silver foil hot stamping, so it is also called fake silver foil. Due to the soft texture, good ductility and silvery white luster of aluminum, if the calendered sheet is mounted on offset paper with sodium silicate and other substances to make aluminum foil, it can also be printed. However, the aluminum foil itself is easy to oxidize and the color becomes dark, and it will fade when rubbed or touched. Therefore, it is not suitable for hot stamping on the covers of books and periodicals that are stored for a long time. In recent years, air conditioners have been ...

Problems solved by technology

However, the aluminum foil itself is easy to oxidize and the color becomes dark, and it will fade when rubbed or touched. Therefore, it is not suitable for hot stamping on the covers of books and periodicals that are stored for a long time. In recent years, air conditioners have been used more and more. Aluminum foil is used to make air conditioner heat exchangers Fin material, generally called air-conditioning aluminum foil, requires sufficient surface corrosion resistance, therefore, it needs passivation treatment
