Abstract

The invention relates to a high-adhesion water transfer printing water-based paint and a preparation method thereof. The water-based paint comprises the following components by mass: 40-60 parts of amodified water-based acrylic resin dispersoid, 5-10 parts of a waterborne polyurethane dispersoid, 5-10 parts of water-based cellulose acetate, 0.1-0.5 part of a water-based defoaming agent, 0.5-1 part of a water-based anti-settling auxiliary agent, 0.1-0.5 part of a water-based wetting agent, 0.1-7 parts of a water-based dispersing agent, 0.1-0.5 part of a water-based anti-corrosion auxiliary agent, 10-15 parts of a film-forming assistant, 10-15 parts of a water-based pigment, 10-15 parts of deionized water and 0.2-1.0 part of a neutralizing auxiliary agent. Compared with the prior art, the high-adhesion water transfer printing water-based paint provided by the invention is water-based and environment-friendly, and excellent in adhesive force performance, also has the original excellent performance of water transfer printing coatings, and is high in adhesive force obtained by modification of matrix resin and proportioning of a formula.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a high-adhesion water transfer printing water-based coating and a preparation method thereof. Background technique [0002] The water-based process of coatings and ink products is increasingly intensified. In order to meet the water-based process of such products, the research of water-based coatings has become a hot spot. [0003] At present, solvent-based coatings are widely used in transfer coatings for automotive interior parts. The solvent content in solvent-based coatings is often above 40%, which not only pollutes the environment, but also causes harm to the health of painting workers. As people pay more and more attention to health and environmental protection, the state has also formulated the requirements for the air quality inside the car, and imposed consumption tax on paint exceeding 420g / L. The VOC requirements of automobile interior coatings are gradually increased by vari...
