The present invention specifically relates to a plastic weather-resistant color masterbatch, comprising the following components in parts by weight: low-density polyethylene, linear low-density polyethylene, nano-titanium dioxide, pigment, nano-calcium carbonate, a modified polyester amide dispersant, antioxidant 1010, a light stabilizer and a lubricant. The preparation method comprises the steps: mixing and dispersing after pretreatment; feeding the dry-mixed material into a twin-screw extruder, setting extruder temperature, screw speed and melt pressure parameters, and performing intelligent regulation through a real-time online monitoring and feedback control system to ensure efficient dispersion of pigment and quality of the color masterbatch; cooling the color masterbatch melt with water and air, and cutting into particles of specified size through a pelletizer. The present invention prepares a plastic weather-resistant color masterbatch with excellent weather resistance through the above formula and process.
