Abstract

The invention discloses a waterborne bronze powder pigment for printing ink. The waterborne bronze powder pigment for printing ink is characterized by comprising the following components in parts by weight: 40-60 parts of flaky bronze powder, 8-10 parts of tetraethyl orthosilicate, 0.1-0.3 part of a silane coupling agent A-151, 0.1-0.2 part of sodium benzoate, 3-5 parts of polyethylene glycol, 0.1-0.2 part of palm oil, 0.2-0.4 part of sorbitol, 0.5-1 part of poloxamer, 0.05-0.1 part of bamboo leaf flavonoid, 0.05-0.1 part of myristic acid, 0.05-0.1 part of coconut oil fatty acid diethanolamide, 0.1-0.2 part of polydimethylsiloxane and 0.5-1 part of compound auxiliaries. The waterborne bronze powder pigment has high dispersity in a water-based medium, is stable in property, high in brightness and good in metallic sense and can be applied to the fields of printing ink and screen printing ink which are of an aqueous system.

Description

technical field [0001] The invention relates to the field of metal pigments, in particular to a water-based copper-gold powder pigment for ink 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 pig...
