Problems solved by technology

However, the solvent resistance of the dye is poor, and its color is easy to precipitate when it encounters a solvent, which makes the bronzing products prone to the problem of color fading during production and use.
In order to solve the problem that the color is easy to fade, the existing technology will increase the percentage of dye used, but if the percentage of dye used is high, the surface quality of bronzing coating will be relatively poor after coating
[0003] Compared with dyes, pigments have better heat resistance, weather resistance and solvent resistance, and the product has high color brightness. However, when pigments are used in bronzing coatings, the light transmittance of bronzing products will be poor, thus making bronzing products less transparent. lack of market competitiveness

Abstract

The invention relates to the technical field of bronzing paint, in particular to a bronzing paint and a preparation process thereof. A bronzing paint, comprising: acrylic resin, organic pigment, metal complex dye, butanone, methyl isobutyl ketone and dispersant. The preparation process of the bronzing paint comprises the following steps: Step 1, dispersing the organic pigment in an acrylic resin to obtain a pigment dispersion; Step 2, mixing methyl ethyl ketone and methyl isobutyl ketone evenly; Step 3, stirring at a slow speed Slowly add the pigment dispersion to the mixed solvent in the container, and increase the stirring speed while adding to obtain the first color paste; step 4, add the metal complex dye to the mixed solvent to obtain the second color paste; step 5, the first The color paste is mixed with the second color paste and stirred evenly to obtain the third color paste; in step 6, the third color paste and dispersant are added to the acrylic resin and stirred evenly to obtain bronzing paint. The bronzing coating has the advantage of good solvent resistance, so that the bronzing products have good light transmittance.

Description

technical field [0001] The invention relates to the technical field of bronzing paint, in particular to a bronzing paint and a preparation process thereof. Background technique [0002] In the hot stamping printing industry, color is an important factor affecting the appearance quality of hot stamping products. In the prior art, since dyes are easy to dissolve and have better transparency (transparency, that is, the degree of light transmission) after dissolution, dyes are commonly used as toners in bronzing coatings. However, the solvent resistance of the dye is poor, and its color is easy to precipitate when it encounters a solvent, which makes the bronzing product prone to the problem of color fading in the process of production and use. In order to solve the problem that the color is easy to fade, the existing technology will increase the percentage of the amount of dye, but if the percentage of the amount of dye is high, the surface quality of the bronzing paint after ...
