Abstract

Aiming at the problems of low spraying efficiency, high labor intensity, high coating loss, non-uniform coating film thickness and the like due to the fact that a thermal transfer coating is formed onthe surface of a metal aluminum base material and a polyurethane powder spraying process is mostly used for construction in the prior art, performance indexes cannot meet thermal transfer requirements in practical application, and a transfer image effect is not ideal. The invention provides a heat transfer printing coating which is prepared by mixing the following components in parts by weight: 30-60 parts of polyester resin, 10-35 parts of amino resin, a proper amount of catalyst and a proper amount of solvent. The heat transfer printing coating is used in cooperation with polyester resin primer of a metal aluminum base material, the surface of the primer is coated with the heat transfer printing coating through a roller coating process, the thermal transfer coating can be formed throughcontinuous high-speed production, and the heat transfer printing coating has the advantages of being high in roller coating production efficiency, high in yield, small in environmental harm and the like and has a good thermal transfer effect.

Description

technical field

[0001] The invention belongs to the technical field of coatings, and in particular relates to a thermal transfer paint which is coated on the primer surface of an aluminum substrate to form a topcoat layer by a roller coating process, and a preparation method of the thermal transfer paint. Background technique

[0002] The thermal transfer process refers to a printing method that uses transfer paper coated with pigments or dyes as a medium to transfer the pattern of the ink layer on the medium to the substrate through heating and pressure. The ink used in thermal transfer printing is usually composed of materials such as colorants and resin base materials. On the surface of the base medium, especially when there is no image-carrying film on the surface of the inorganic material medium, the aforementioned ink cannot form a direct bond with the surface of the inorganic material medium. Therefore, when implementing thermal transfer printing technology on the sur...
