Problems solved by technology

[0002] At present, due to uncontrollable external force factors in the project decoration site, the surface of the wooden decorative parts is easily scratched or small depressions are formed, so it is necessary to repair and restore the wooden decorative parts on site. The traditional method is to use PU paint or PE However, the drying time of the traditional PU paint and PE paint film is relatively long (it takes 5-8 hours for the paint film to dry before proceeding to the next process), which will lead to delays in work and time, and prolong the construction period
[0003] At present, the UV paints used in the market have the characteristics of high efficiency and easy curing. Generally, the UV paint is cross-linked and cured by high-pressure mercury lamps to complete the paint film formation. However, due to the high power of the high-pressure mercury lamps (generally 80W / cm), It has strong light intensity and brightness, strong heat radiation and ozone generation, which requires a supporting cooling system during work. For cost considerations, it is rarely used on construction sites. Therefore, it is necessary to study a short curing time and high availability. , easy maintenance, and wood repair coatings that meet environmental protection and safety requirements are imperative

Abstract

The invention belongs to the field of coatings and particularly relates to a solid color repair primer for LED-UV woodware and a preparation method thereof. The solid color repair primer for LED-UV woodware comprises, by weight, 31-40 parts of amino acrylate resin, 31-40 parts of acrylate resin, 5-10 parts of a monomer, 5-7 parts of a photoinitiator, 0.2-0.4 part of an ant-settling agent, 0.1-0.3part of a wetting dispersant, and 10-20 parts of UV color paste. The solid color repair primer for LED-UV woodware is scraped or brushed on a project construction site to repair the defects of decorative woodware surface, such as paint film scratches and impact marks; film can be formed by full crosslinking and curing just by exposure to ultraviolet from an LED-UV lamp; the primer herein is convenient to construct, efficient and environmentally friendly, and good in safety; the primer herein has the advantages of excellent properties, has good low-energy curing performance, good filling property, good covering performance, good convenience of polishing, re-applicability, zero VOC (volatile organic compounds) volatilization and the like.
