Abstract

The invention discloses an anodic oxidation nickel-free hole sealing agent. The anodic oxidation nickel-free hole sealing agent comprises, by mass percentage, acetate, benzoic acid, phosphoric acid, sodium benzoate, igepon T, fatty alcohol polyoxyethylene ether, POCA, organic tin, potassium stearate, active diluent and deionized water. The anodic oxidation nickel-free hole sealing agent can well perform closing treatment on an anodic oxide film, the hole sealing speed is high, and no pollution is caused to environment; a product after hole sealing does not turn black or green, the surface is bright and clean, no nickel or fluorine is contained, and the requirement of state environmental protection and an European Union ROHS instruction are met. Besides, igepon T, fatty alcohol polyoxyethylene ether, POCA, organic tin, potassium stearate, active diluent and other auxiliary agents are added, the hole sealing effect and efficiency are further improved, and the surface of a material afterhole sealing is made firmer, more stable and resistant to corrosion.

Description

technical field [0001] The invention relates to the technical field of hole sealing of anodic oxidation films, in particular to an anodic oxidation nickel-free sealing agent. Background technique [0002] At present, the use of sealing agents in foreign countries is mainly nickel salt sealing agents. Among them, the high-temperature nickel acetate sealing agent from Japan and the normal temperature nickel acetate sealing agent from Europe and America are the main ones. The sealing quality of high-temperature nickel acetate sealing agent is better than that of normal temperature nickel acetate sealing agent, and it is more widely used. The principle is that nickel ions interact with water and surfactants at a certain pH, and hydrolysis and hydrolysis products are properly aggregated. Enter the pores of the oxide film on the aluminum surface to seal the pores; the pH buffer agent plays the role of stabilizing the pH value of the solution and controlling the degree of hydrolys...
