Zusammenfassung:Disclosed is a polypropylene composition, comprising the following components in parts by weight: 40-99 parts of a polypropylene resin; 15-30 parts of an ethylene-α-olefin copolymer; 0.2-1 part of an antimicrobial agent; and 1-3 parts of a polypropylene grafted polydimethylsiloxane. By controlling the melt index of an elastomer, the distribution of the modified polydimethylsiloxane and antibacterial agent can be improved, thus improving the antimicrobial and stain-resistant effects of the polypropylene composition.
