Aluminum alloy dyeing additive and dyeing method

Abstract

The invention relates to the technical field of aluminum alloy, in particular to an aluminum alloy dyeing additive and a dyeing method. The aluminum alloy dyeing additive comprises the following raw materials of, by weight, 30-35 parts of nickel sulfate, 8-12 parts of stannous sulfate, 18-22 parts of sulfuric acid, 16-20 parts of a coloring stabilizer and 13-18 parts of a synergist. The dyeing additive is used for aluminum alloy dyeing, the dyeing efficiency and uniformity can be improved, the dyeing effect and the product yield are improved, the problems of color flowing, different colors andthe like in the dyeing process are solved, the service life of coloring liquid is prolonged, and aluminum alloy has a good appearance effect, good durability and long service life. An aluminum alloydyeing pretreatment method using the aluminum alloy dyeing pretreatment agent is simple and convenient to operate and easy to control, the dyeing efficiency and uniformity can be remarkably improved,the dyeing effect and the product yield are improved, an aluminum alloy dyeing workpiece with a uniform color and a good appearance effect can be obtained, and the aluminum alloy dyeing pretreatment method is suitable for industrial mass production.

Description

technical field [0001] The invention relates to the technical field of aluminum alloys, in particular to an aluminum alloy dyeing additive and a dyeing method. Background technique [0002] With the development of society and the advancement of science and technology, aluminum alloys have been increasingly well used. The existing technology often uses anodizing and dyeing processes to improve the durability and decorative effect of aluminum alloy products. However, during the dyeing process of the existing dyeing process, there are often problems such as uneven distribution of dyeing agents and decreased dyeing ability, which easily lead to defects such as flow marks and mottled products, easy to appear flow color, heterochromatic color, and the dyeing effect is not high , and the dyeing effect is not good, which affects product yield and durability, and needs further improvement.
