The invention provides a fade-resistant color masterbatch for lawn and its preparation method, including the following steps: mixing low-density polyethylene, polyethylene wax and magnesium stearate under high-speed stirring, heating and keeping a constant temperature until polyethylene wax is completely melted; adding high-stability pigment particles and stirring until the surface of low-density polyethylene is fully coated with pigments to obtain a mixed material; heating the twin-screw extruder to 130℃, adding the mixed material for extrusion and granulation to prepare the fade-resistant lawn color masterbatch. Electrospinning technology is adopted to prepare fibers from porous materials with different pore sizes loaded with pigments. Through electrostatic interaction between positively charged chitosan and negatively charged attapulgite nanorods, an interphase layer is formed between electrospun fibers to form a dense nano-coating. This compact interface structure protects pigment stability, improves light resistance and aging resistance, and enhances compatibility and dispersion with matrix resin.
