Embodiment 1

[0034] 1. Prepare the thermal transfer coating of this embodiment 1, according to the following weight component ratios:

[0035] 45 parts of RP7555 type polyester resin, 14 parts of CYMEL 303 type amino resin, 0.8 parts of p-toluenesulfonic acid catalyst, S-100# aromatic hydrocarbon solvent, ethylene glycol butyl ether and propylene glycol methyl ether acetate at 6:2:2 20 parts of mixed solvents obtained by weight ratio.

[0036] 2. Prepare the preparation method of thermal transfer coating according to the following steps:

[0037] Put the polyester resin and amino resin in the required parts by weight into the cylinder, and disperse for 5-10 minutes at a speed of 600-800 rpm;

[0038] Adjust the rotation speed to 400-600 rpm, put in the catalyst of the above-mentioned parts by weight and the mixed solvent of half of the above-mentioned parts by weight, and disperse for 10-15 minutes at a rotation speed of 600-800 rpm;

[0039] Adjust the rotation speed to 400-600 rpm and ...

Embodiment 2

[0042] Prepare the thermal transfer paint of present embodiment 2, by following weight component ratio:

[0043] 55 parts of RP7555 polyester resin, 30 parts of CYMEL 303 amino resin, 0.8 parts of p-toluenesulfonic acid catalyst, 0.4 parts of EFKA-3777 leveling agent, 5 parts of OK520S matting powder, S-100# aromatic hydrocarbon solvent and 30 parts of mixed solvents obtained by butyl glycol ether in a weight ratio of 5:5.

[0044]Referring to the preparation steps of Example 1, in the input step of the catalyst and part of the solvent, 0.4 parts of the leveling agent are synchronously added; then an additional step is added: adjust the speed to 400-600 rpm, put in 5 parts of matting powder, Disperse at 600-800 rpm for 10-15 minutes, and the detection fineness is below 10 μm; other steps remain unchanged, and the thermal transfer coating of Example 2 can be obtained.

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...
