Problems solved by technology

[0007] 3. After matching, there is a certain period of use
[0008] 4. High free toluene diisocyanate (TDI) is harmful to human body
Ordinary type is easy to yellow, and the price of non-yellowing type is high
[0012] (3) The drying speed is greatly affected by the temperature
Its curing is greatly affected by the ambient temperature, humidity, and the plate, coupled with the difference in batches, it brings a lot of difficulties to the deployment of the coating, and the amount of accelerator and curing agent is not well controlled, which will directly affect the performance of the coating.
[0020] (3) The film-forming mechanism of PE paint is free radical-induced polymerization. Once the components are mixed, free radicals will be generated and polymerized. The service life is generally within 20 minutes, which brings a lot of inconvenience to the construction.
For the same finishing process (such as spraying, flow coating), the equipment or process of using PE paint is much more complicated than that of using PU paint and other coatings, and the equipment cost is high
[0021] (4) The defect is that the surface is dry and the curing time is long, which affects the production efficiency

Abstract

The invention relates to an ultraviolet solidified yellowing resistant and glossy woodenware paint, which comprises components of A and B. Wherein, component A is composed of epoxy acrylate (EA), polyurethane acrylate (PUA), polyester acrylate (PEA), an active diluent, an antifoaming agent, a levelling agent, a dispersant and a photoinitiator, while component B is composed of butyl acetate, B fat and xylene. According to the application technology, component A and component B are mixed at a proportion of 100:20-50 and then used for application. The paint of the invention has the advantages of strong glossiness, high hardness, scratch resistance, yellowing resistance, good fullness of color, fast drying speed and simple application.
