Abstract

The invention relates to a waterborne metal complex dye. The waterborne metal complex dye is prepared by mixing the following raw materials in percentages by mass: 10 to 30% of metal complex toner, 40 to 60% of an organic solvent intermiscible with water, 0.1 to 1% of a pH regulator, 1 to 20% of a surfactant and 5 to 10% of water. Compared with the prior art, the invention has the following beneficial effects: the waterborne metal complex dye can be used as a color matching product of an environment-friendly waterborne coating, is completely intermiscible with a waterborne coating product in the prior art, is of a uniform state under slight stirring, has excellent color transparency and brightness, is insusceptable to blistering and precipitating compared with a waterborne coating in the prior art, has a formula free of national disabled harmful solvents like benzene, has simple process and does not need high shear dispersion during production, saves man hours and energy consumption, and can be extensively applied to waterborne coatings like a waterborne wood coating, waterborne printing ink, a waterborne leather coating, a waterborne glass coating and a waterborne metal coating.

Description

technical field [0001] The invention relates to a dye, in particular to a water-based metal complex dye and its application. Background technique [0002] Because metal complex dyes have greater performance advantages than other types of colorants, they have been widely used in solvent-based products, and are widely used in wood coloring, glass surface coloring, metal surface coloring, etc. Traditional solvent-based dyes mainly dissolve the complex dye particles in ketones, esters, and aromatic hydrocarbon solvents, and keep the solution stable. During the application process, the dissolved color essence is added to the paint products to ensure no Precipitates from paint systems. However, since the metal complex dyes themselves are not water-soluble, it is a very urgent task to develop high-performance water-based metal complex dyes that can be used in water-based applications under the current trend of water-based coating surfaces.
