Problems solved by technology

[0003] In order to endow carbon fiber composites with richer color and texture effects, fiber dyeing technology or prepreg dyeing technology is generally used to prepare carbon fiber composites of different colors, but the color effects obtained are very limited, which limits its application in the field of carbon fiber composites. wider use
However, if the traditional dye is used to realize the colored transparent coating, its weather resistance is poor, and it is not suitable for the protection of carbon fiber substrates, and long-term use is prone to color difference
In addition, most of the transparent coatings currently used for carbon fiber composite materials are mainly medium-solid or low-solid coatings, and their VOC content is relatively high (VOC>420g / L), which is not conducive to environmental protection.
