Abstract

The invention discloses a wear-resistant aqueous aluminum pigment which is prepared from the following raw materials in parts by weight: 40-60 parts of laminar aluminum powder, 8-10 parts of tetraethoxysilane, 0.1-0.3 part of a silane coupling agent A-151, 1-2 parts of zircon power, 1-2 parts of polytetrafluoroethylene micropowder, 0.5-1 part of water soluble wool fat, 0.5-1 part of cellulose acetate butyrate, 0.5-1 part of a silicone acrylic emulsion, 0.5-1 part of glyceryl trithylhexanoate, 3-5 parts of polyethylene glycol, 0.1-0.2 part of lauryl sodium sulfate, 0.05-0.1 part of itaconic acid and 0.5-1 part of compound auxiliaries. The aluminum pigment disclosed by the invention has good wear resistance, and is long in service life, high in dispersibility in aqueous media, stable in property and suitable for aqueous systems.

Description

technical field [0001] The invention relates to the field of metal pigments, in particular to a wear-resistant water-based aluminum pigment and a preparation method thereof. Background technique [0002] Nowadays, with the development of industrialization, the global environment is deteriorating, and environmental protection issues are getting more and more attention. Traditional metallic pigments have bright metallic luster and high hiding power, and have the advantages of high decoration and high protection. They are widely used and have a huge market. However, traditional solvent-based metallic pigments use a large amount of organic solvents in the application, which are discharged into the environment during the coating process, which is easy to cause pollution. Since most of the organic solvents of water-based metallic pigments are replaced by water, the pollution discharge during the coating process is greatly reduced. Therefore, the use of water-based metallic pigmen...
