Problems solved by technology

[0002] The white paint in the prior art mostly adopts ultraviolet light curing method. If the concentration of color paste in the paint is relatively high, especially when the coating is thick, it is difficult for ultraviolet light to penetrate the bottom, resulting in insufficient curing, and It will also lead to poor adhesion between coatings; and in the case of low concentration of color paste, UV curing is used, although it can be cured relatively completely, but the covering power is not enough
And to achieve good hiding power, the

Abstract

The invention relates to the technical field of coatings, in particular to an electron beam cured high-wear-resistant scratch-resistant white coating and a preparation method and a construction methodthereof. The electron beam cured high-wear-resistant scratch-resistant white coating comprises white slurry, urethane acrylate with six functional groups, trimethylolpropane triacrylate, dipentaerythritol hexaacrylate, a dispersing agent, polyether modified dimethyl siloxane and a defoaming agent. The preparation method of the electron beam cured high-wear-resistant scratch-resistant white coating comprises the following steps: first step, preparing white slurry; and second step, preparing the white coating. The electron beam cured high-wear-resistant scratch-resistant white coating has the characteristics of being high in color paste concentration, excellent in hiding power, capable of avoiding the fact that a white primer coats for many times and is combined to a white finish paint or varnish to achieve a good hiding power effect, capable of enabling a cured white coating layer to be better in yellowing property, high in hardness, wear-resistant, scratch-resistant, good in yellowingproperty, good in adhesive force, good in leveling property and the like.

technical field [0001] The invention relates to the technical field of coatings, in particular to an electron beam-cured white coating with high wear resistance and scratch resistance, as well as a preparation method and a construction method thereof. Background technique [0002] The white paint in the prior art mostly adopts ultraviolet light curing method. If the concentration of color paste in the paint is relatively high, especially when the coating is thick, it is difficult for ultraviolet light to penetrate the bottom, resulting in insufficient curing, and It will also lead to poor adhesion between coatings; and in the case of low concentration of color paste, UV curing is used. Although it can be cured relatively completely, the hiding power is not enough. And to achieve good hiding power, the existing technology is to use multiple coatings of white primer combined with white topcoat (the proportion of titanium dioxide in the topcoat is low) or varnish to achieve goo...
