Problems solved by technology

[0003] However, due to the defects of the ingredients, the existing car topcoats have shortcomings such as insufficient fullness and low vividness of image, which lead to poor aesthetics and poor chemical resistance of the car. At the same time, the raw materials cannot be fully uniformed in the preparation process. The fineness of the mixed raw materials cannot be guaranteed when grinding and discharging, which affects the quality of the finished product
