Abstract

The invention discloses a water-based coloring layer coating for a transfer film and a preparation method of the water-based coloring layer coating and particularly relates to a pure water-based coloring layer coating for a heat transfer film (alumite). The coating is prepared from, by mass, 20-60 parts of styrene-maleic anhydride polymerized resin water solution, 20-50 parts of polyacrylic resin water solution, 3-10 parts of water-based reinforced resin, 0-3 parts of water-based cross-linking agent, 0-1 part of water-based wetting leveling agent, 0-1 part of water-based defoamer, 0-1 part of PH modifier and 0-30 parts of deionized water. The styrene-maleic anhydride polymerized resin water solution and the polyacrylic resin water solution are prepared through a hydrothermal alkali dissolution method, and the product is prepared through a stirring and mixing method according to a feeding sequence. The product is purely based on water, environmentally friendly and safe, and can completely replace similar solvent type products on the market, and various properties are qualified through detection.

Description

technical field [0001] The present invention relates to a functional thin film coating product, relates to a water-based coloring layer coating for a transfer film and a preparation method thereof, in particular to a pure water-based coloring layer coating for a thermal transfer film (anodized aluminum) and its preparation method. Background technique [0002] Transfer printing is a special printing technology. Usually, the color pattern is transferred to the surface of other materials through the transfer film and the adhesive is hot-pressed, and the color coating or color pattern on the transfer film is transferred to the surface of the material. Processes on other material surfaces. [0003] This type of transfer film usually includes: 1. Thermal transfer film (anodized aluminum, bronzing film): can be subdivided into anodized aluminum hot stamping foil with aluminized layer, pigment foil without aluminized layer; 2. .Transfer printing film: usually print the coated col...
