Abstract

The invention relates to a hydroxyacrylic resin material composition, a preparation method and application thereof. In the present invention, a suitable solvent is selected and matched with a dispersant and an ultraviolet light absorber, together with hydroxyacrylic resin, matte powder, anti-sediment slurry, and drier to form a specific formula. When the paint formula formed by this specific formula, curing agent and thinner is sprayed on the surface of the carbon fiber layer and then PUR is injected, the carbon fiber layer and the PUR layer of the obtained workpiece have strong adhesion, which can significantly reduce the appearance of bubbling or white spots, and effectively avoid delamination. Other advantages of the present invention: the workpiece prepared with the paint formula also has good hardness, flexibility, impact resistance and yellowing resistance.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to a hydroxyacrylic resin material composition and a preparation method and application thereof. Background technique [0002] Many automotive interior parts are composed of carbon fiber and PUR (polyurethane). The production process is to inject a layer of PUR with a thickness of 1mm on the carbon fiber layer, and bake it in a mold at 150°C for 20 minutes to cure. Because PUR is hard and thick, the internal stress is very large, and the adhesion to carbon fiber parts is not good. In order to increase the adhesion between PUR and carbon fiber, it is necessary to spray a layer of adhesion enhancer on the carbon fiber layer to enhance the interlayer adhesion. . [0003] However, when the traditional adhesion enhancer is sprayed on the carbon fiber layer and then injected into PUR, the adhesion between the formed PUR layer and the carbon fiber layer is not good. Bubbling or...
