The invention discloses a flame-retardant color masterbatch and a preparation process thereof, belonging to the technical field of polymer materials. The flame-retardant color masterbatch comprises the following raw materials in parts by weight: carrier resin: 65‑90 parts, modified magnesium hydroxide: 25‑45 parts, colorant: 15‑45 parts, dispersant: 1‑5 parts, antioxidant: 0.05‑1 part. The preparation steps are as follows: S1. Weighing according to parts by weight, adding the carrier resin, modified magnesium hydroxide, colorant, dispersant and antioxidant into a high-speed mixer for uniform mixing to obtain a mixture; S2. Transferring the mixture to a twin-screw extruder, melt-mixing, extruding, pelletizing and drying to obtain a flame-retardant color masterbatch. The prepared flame-retardant color masterbatch has excellent flame retardant properties and mechanical properties, and is stable and durable; at the same time, the raw materials for preparing the flame-retardant color masterbatch are readily available, the processing process is simple, and large-scale promotion can be realized.
