The invention discloses a preparation method of a chemical solvent-resistant color masterbatch for chemical drums and the color masterbatch thereof, wherein the preparation method comprises preparing a colorant semi-finished product, preparing a second mixture, preparing a second mixture and preparing a finished color masterbatch. The segmented processing technology not only avoids performance degradation of materials due to excessive temperature during processing, but also promotes uniform distribution of components through multiple mixing steps. In addition, a three-roll mill is used to grind the colorant semi-finished product to reduce particle size, ensuring the mixing effect of the second blending and further improving the uniformity of material distribution.
