The invention discloses a preparation method of high-strength modified engineering plastics, relating to the field of engineering plastics. The specific steps are: Adding matrix resin, toughener, antioxidant, lubricant and plasticizer into a high-speed mixer for preliminary mixing; stopping feeding to add reinforcing fibers and continuing mixing; extruding the mixture via a twin-screw extruder, cooling and pelletizing to obtain modified engineering plastics. By optimizing the formula and processing technology, the mechanical strength of engineering plastics is effectively improved.
