Composition for colorful paint and preparation method thereof

The preparation method comprises the following preparation process: preparing the following raw material components in percentage by weight: 40 to 50 percent of toning base paint, 10 to 20 percent of granulation liquid, 10 to 20 percent of continuous phase and 10 to 20 percent of antibacterial composite material; the preparation method comprises the following steps: mixing color of the color-mixing base paint, adding the color-mixing base paint into granulation liquid, granulating by utilizing a PDC (Polycrystalline Diamond Compact) colorful data experiment slicing machine, uniformly mixing color granules, sequentially adding the continuous phase and the antibacterial composite material, and uniformly stirring to obtain the colorful coating composition. The multicolor paint has the advantages of excellent color permeability resistance, excellent water white resistance and stable viscosity, and has a wide application prospect in engineering outer wall coating. 本发明公开了一种多彩涂料用组合物及其制备方法，包括以下制备过程：按照重量百分比计，配制以下含量的原料
