A kind of electron beam cured highly wear-resistant and scratch-resistant white paint and its preparation method and construction method

Abstract

The present invention relates to the technical field of coatings, in particular to an electron beam-cured highly wear-resistant and scratch-resistant white paint and its preparation method and construction method. The electron beam-cured highly wear-resistant and scratch-resistant white paint includes white slurry , Hexafunctional urethane acrylate, trimethylolpropane triacrylate, dipentaerythritol hexaacrylate, dispersant, polyether modified dimethylsiloxane and defoamer. The preparation method of the highly wear-resistant and scratch-resistant white paint cured by electron beams comprises: the first step, the preparation of white slurry; the second step, the preparation of white paint. The high wear-resistant and scratch-resistant white paint cured by electron beams has high concentration of color paste and excellent hiding power, which can avoid the need to apply white primer multiple times and combine with white topcoat or varnish to achieve good hiding power. Advantages, and can make the yellowing of the cured white coating better, and has the characteristics of high hardness, wear resistance and scratch resistance, good yellowing, good adhesion, and good leveling.

Description

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...

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 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 good hiding power, which leads to The construction process of the white paint in the prior art is complex and the production cost is high

[0003] In addition, the prior art uses ultraviolet light to cure white (or other color) coatings, and the photoinitiator in the coating often appears to remain or migrate, resulting in the problem of poor yellowing in the later stage
