Problems solved by technology

[0003] The whole process of the double-layer method needs to wait for several minutes between each step, requires the cooperation of multiple people, and requires manual operation, which is slow; the pattern often cannot be transferred completely, and some parts will be damaged, and it cannot be used on products with concave and convex surfaces.
The single-layer method cannot produce large-sized products, nor can it be used on products with obvious unevenness
In addition, the two methods are difficult to maintain the color and effect during the baking process of some glass and ceramic products that require high-temperature baking.

Abstract

The invention provides a high-temperature-resistance hydrographics transfer printing coating composition and a preparing method thereof. The coating composition comprises polyfunctionality resin, polyacrylate resin, a solvent, a conventional cross-linking agent and a high-temperature activation cross-linking agent. The preparing method comprises the steps of placing the polyfunctionality resin, the polyacrylate resin, the conventional cross-linking agent and the high-temperature activation cross-linking agent into the solvent in sequence, conducting uniform mixing, and then conducting curing; adjusting solid content to be 10-50% after curing ends, and conducting stir-discharging, so that the high-temperature-resistance hydrographics transfer printing coating composition is obtained. The high-temperature-resistance hydrographics transfer printing coating composition and the preparing method thereof have the advantages that a bi-component formula is adopted, and a good luster effect can be maintained in the later-stage high-temperature baking process; film forming property is high, and the problem of integral transfer failure can be solved to a large extent during transfer printing; the tolerance of later-stage operation to a concave-convex interface is high; waiting is not needed in each step of operation interval, and production efficiency is improved greatly.

Description

technical field [0001] The invention relates to a high temperature-resistant water transfer printing coating composition and a preparation method thereof, belonging to the technical field of coatings. Background technique [0002] Water transfer printing is a printing method that uses water pressure to hydrolyze the color transfer paper / plastic film with special patterns. The existing water transfer printing methods mainly include double-layer water transfer printing and single-layer water transfer printing. Double-layer water transfer printing is to print the pattern on one side of the double-layer water transfer printing paper first. After it is completely dry, apply a layer of varnish on an offset printing machine, or spray a layer of paint with a spray gun, and let it dry completely after 24 hours. ;When using, first separate the double-layer transfer paper into two layers, keep the patterned copy paper, then spray a layer of transparent nitro paint evenly on the target...
