Antibacterial polypropylene plastic and preparation method thereof

The invention provides antibacterial polypropylene plastic and a preparation method thereof, and relates to the field of one-dimensional nanowire antibacterial agents and antibacterial plastics. According to the invention, a one-dimensional copper-doped rutile titanium dioxide nanowire antibacterial agent is compounded in polypropylene, so a polypropylene composite material with an antibacterial function is prepared, and the polypropylene composite material shows an excellent antibacterial effect. The copper-doped rutile titanium dioxide nanowire antibacterial agent used in the invention is simple in preparation method and uniform in morphology, and has metal ion antibacterial and visible light synergistic antibacterial functions. A certain amount of the copper-doped rutile titanium dioxide nanowire antibacterial agent is added into the polypropylene plastic, so the common plastic is endowed with excellent antibacterial property and mechanical property. 本发明提供了一种抗菌聚丙烯塑料及其制备方法，涉及一维纳米线抗菌剂和抗菌塑料领域。本发明通过在聚丙烯中复配一维铜掺
