Problems solved by technology

Both of the above two technologies add a curing agent to the paint, but the addition of the curing agent makes it easy to cure when the paint is prepared with the machine liquid, and it is unstable and easy to cure during storage, resulting in scraps and increased costs.

Abstract

The invention relates to the technical field of gold stamping paint, especially to single component gold stamping paint and a preparation method and an application thereof. The single component gold stamping paint comprises the following raw materials, by weight: 5-25 parts of water-based solid acrylic resin, 5-25 parts of rosin resin, 1-10 parts of amino resin, 1-5 parts of cellulose nitrate, 0.1-1 part of auxiliary agents, and 60-80 parts of organic solvents. The preparation method includes the following steps: dividing the weighed organic solvents into two parts, adding the water-based solid acrylic resin into one part of the organic solvents, heating the mixture to 52-58 DEG C, and keeping the temperature and stirring the mixture for 1-2 h to obtain a acrylic resin solution; adding therosin resin and the cellulose nitrate into the other part of the organic solvents while stirring, adding the amino resin, continuing to stir and mix, adding the acrylic resin solution, stirring and well mixing the mixture, adding the auxiliary agents, and then stirring and well mixing the mixture to obtain the single component gold stamping paint. The gold stamping paint of the invention is applied to cloth stamping and gold stamping without adding a curing agent, and so the gold stamping paint is not prone to curing when being put on a machine and stored, which avoids leftover paint and saves the cost.

Description

technical field [0001] The invention relates to the technical field of bronzing paint, in particular to a single-component bronzing paint and a preparation method and application thereof. Background technique [0002] Hot stamping, also known as "hot stamping", is a printing decoration process that heats and foils a metal printing plate to emboss golden characters or patterns on printed matter. Fabric hot stamping technology is a kind of cloth dyeing technology. In clothing printing, hot stamping has become a fashion symbol because of its brilliance. Because the overall effect of the hot stamping fabric looks elegant and fashionable, it is favored by more and more beauty lovers. . Fabrics treated with bronzing paint have more choices of colors, patterns and functions. It can realize both full-page hot stamping and partial clear hot stamping, which can create amazing metallic effects and enhance the unique charm of textiles. [0003] Existing bronzing coatings for hot clot...
