Abstract

In order to solve the problems that a film transfer coating in the prior art is not resistant to high temperature and hot pressing, aluminizing brightness is poor and the coating loses gloss after film transfer, the invention provides a water-based aluminizing transfer coating. The water-based aluminizing transfer coating comprises water-based resin, silicon-modified water-based polycarbonate and zirconium-modified water-based polycarbonate in different proportions. The invention further provides a preparation method and application of the water-based aluminizing transfer coating. The coating is applied to leather, wallpaper, ironing cloth, tablecloth or alumite heat transfer films. The coating provided by the invention has excellent properties of temperature resistance, hot pressing resistance, good brightness after aluminizing and color addition, and also has excellent properties in stripping property and flexibility.

Description

technical field [0001] The invention belongs to the technical field of releasable film coatings, and in particular relates to a water-based aluminum plating transfer coating, a preparation method and an application thereof. Background technique [0002] The traditional transfer coating first uses products such as release layer, coloring layer and heat-resistant protective layer at the same time, and then transfers the coating to the target substrate by vacuum aluminum plating and gluing. In the traditional transfer coating process, on the one hand, multiple coatings reduce production efficiency and affect production capacity; on the other hand, the simultaneous use of multiple products not only increases the cost of raw materials, but also increases the interlayer adhesion, recoating leveling and mutual penetration of each product. There are also many uncertainties, and even these problems have become difficult problems for the industry. [0003] The film transfer coating i...
