The invention relates to the technical field of color masterbatches and specifically relates to an antistatic and antibacterial color masterbatch and a preparation method thereof. The color masterbatch is prepared from the following raw materials in parts by weight: 48-63 parts of polypropylene resin, 19-36 parts of toner, 2-7 parts of dispersant, 0.5-1.5 parts of antistatic agent and 0.5-1.5 parts of antibacterial agent, wherein the polypropylene resin is metallocene polypropylene of which the melt index is 5-25g/10min and the density is 0.886-0.924g/cm ; the antistatic agent is a mixture of octadecylamine polyoxyethylene ether, dodecylamine polyoxyethylene ether and monoglyceric stearate in the weight ratio of (0.5-1.5) to 1 to (2.4-3.2); the antibacterial agent is a mixture of silver-loaded zeolite and silver-loaded cobalt phosphate in the weight ratio of (1.5-2.5) to 1. The antistatic and antibacterial color masterbatch is good in antistatic effect, and has a relatively high safety coefficient, good antibacterial function and low harm.
