The invention discloses an additive for modified plastics and its preparation method, relating to plastic processing technology. The specific process: Mix polyolefin and filler in a high-speed mixer, add coupling agent for continuous blending, then incorporate antioxidant and lubricant for final mixing. The mixture is extruded and granulated by a twin-screw extruder to obtain the plastic modifier additive. This method can remarkably enhance the mechanical properties, thermal stability and processability of plastics. The additive features simple preparation, low cost and suitability for large-scale industrial production.
