Preparation method of high-toughness modified engineering plastic

The invention discloses a preparation method of a high-toughness modified engineering plastic. A main material is a ternary material prepared by a special material through a process, and the material is excellent in toughness and rigidity; flame-retardant materials such as graphene, titanium dioxide and a halloysite nanotube in a modified anti-aging flame-retardant system and anti-aging materials such as wollastonite needle-like fibers form a compound synergistic effect, so that the flame retardance and the anti-aging property of the engineering plastic are extremely enhanced; the dispersibility and compatibility of highly dispersed nano calcium carbonate and the toughening main material are good, and the flowing property and processing property of the toughening main material are improved, and the engineering plastic is endowed with relatively good physical and mechanical properties, thereby further enhancing the toughness. 本发明公开了种高韧改性工程塑料的制备方法，所述主料为特定材料和工艺制得的三元材料，其韧性、刚性皆优；改性抗老化阻燃体系中石墨烯、钛白粉、埃洛石纳米管等阻燃材料与硅灰石针状
