Problems solved by technology

Aluminum alloy anodic oxidation film sealant formulations often contain chemical substances such as nickel acetate, nickel fluoride, and sodium fluoroborate that are likely to pollute the environment; the cold sealing method generally controls the sealing temperature between 22°C and 35°C. It causes a large amount of medicine consumption and many negative effects of control factors, especially for the film thickness greater than 25um, the qualified product rate is low; the medium temperature sealing method generally controls the sealing temperature between 55°C and 70°C, and the energy consumption is high.

Abstract

The invention discloses a method for preparing an aluminum alloy anodic oxide film sealant, which comprises the main processes of adding deionized water, zinc acetate, magnesium acetate, cerium acetate, surfactant, hydration promoter and sublimation preventing agent into a reaction kettle in turn, and mixing, stirring and heating the components to form the sealant. One of the important components of the sealant is sublimation preventing agent which is prepared by mixing the deionized water, polyvinyl alcohol and sodium hexametaphosphate together and then stirring and heating the mixture in the reaction kettle. The raw materials adopted by the preparation method do not contain nickel and fluorine elements, so the sealant is favorable for environmental protection; and the sealant reduces energy consumption during use, and improves the qualification rate of aluminum alloy products.

Description

technical field [0001] The invention relates to a preparation method of an aluminum alloy anodic oxidation film sealant; in particular, it refers to a sealing agent for an aluminum alloy anodic oxidation film whose sealing temperature is between 35°C and 45°C and whose formula does not contain nickel and fluorine. Preparation. Background technique [0002] At present, the sealing process of aluminum alloy anodized film in China mostly adopts the cold sealing method and medium temperature sealing method of salt solution containing nickel and fluorine elements. Aluminum alloy anodic oxidation film sealant formulations often contain chemical substances such as nickel acetate, nickel fluoride, and sodium fluoroborate that are likely to pollute the environment; the cold sealing method generally controls the sealing temperature between 22°C and 35°C. It causes a large amount of medicine consumption and many negative effects of control factors, especially for the film thickness gr...
