Description

technical field

[0001] The invention relates to the technical field of surface treatment of metal pigments, in particular to a coated modified aluminum powder pigment, a preparation method and an application. Background technique

[0002] Aluminum powder pigment is one of the most common metallic pigments, and is favored by designers for its unique sparkle, covering and decorative effects. Its consumption has grown rapidly since the last century, and in recent decades it has developed towards high added value and water-phase adaptability. The main application areas are industrial coatings, automotive coatings, decoration, printing inks, plastic processing, etc.

[0003] Traditional aluminum powder pigments are all solvent-based aluminum powders, and the solvent-based products formulated with them contain relatively high organic volatiles, are difficult to clean, and are harmful to the environment and human body. With the continuous development of science and technology, p...
