▎ 摘　　要

NOVELTY - A modified polycarbonate composite material comprises 60-90 pts. wt. polycarbonate resin, 5-30 pts. wt. polypropylene resin, 1-5 pts. wt. compatibilizer, and 0.1-1 pt. wt. silver-graphene nano-enzyme. USE - The modified polycarbonate composite material is used in plastic product (claimed) and used in electronic appliances, automobiles, machinery and communications. ADVANTAGE - The raw material components exhibit synergistic effect. The modified polycarbonate composite material has polypropylene corrosion resistance and easy processing, and has excellent antibacterial properties. The polypropylene has excellent comprehensive performance, good corrosion resistance, processing performance, and low cost, at the same time, it has high heat resistance, high impact and high dimensional stability of polycarbonate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the modified polycarbonate composite material comprising weighing each raw material component, pre-mixing uniformly, and melting and extruding to obtain the modified polycarbonate composite material.
