▎ 摘　　要

NOVELTY - Electromagnetic shielding polypropylene composition comprises 60-80 pts. wt. polypropylene resin, 1-5 pts. wt. metal-organic frameworks (MOFs)-porous carbon material, 5-30 pts. wt. talcum powder, 15-20 pts. wt. toughening agent and 0.3-1 pt. wt. processing additive. The metal center of MOFs in MOFs porous carbon material is magnetic metal. The pore diameter of MOFs porous carbon material is 0.3-0.55 nm. The pore volume is 0.4-0.65 cm3/g. The specific surface area is 1200-1700 m2/g. USE - The electromagnetic shielding polypropylene composition is used for auto component products (claimed). ADVANTAGE - The composition improves mechanical properties and electromagnetic shielding effect by adding MOFs-porous carbon material. The MOFs-porous carbon material has effect of adsorbing odor.
