Durable anti-aging antibacterial polypropylene composite material for automotive interiors and preparation method thereof

The invention relates to a durable anti-aging antibacterial polypropylene composite material for automotive interiors and a preparation method thereof. The composite material is composed of the following components in percentage by mass: 60 to 80% of polypropylene resin, 1 to 20% of elastomer, 1 to 20% of talcum powder, 0.1 to 1% of a lubricant, 0.6 to 1.2% of an antibacterial agent, and 0.1 to 2%of an anti-aging auxiliary agent. The antibacterial agent is selected from silver ions, zinc ions, copper ions, cobalt ions, nickel ions, aluminum ions and the like, and a carrier of the antibacterial agent is a combination of a phosphate carrier with at least one of a zeolite carrier, a clay carrier, a silicon dioxide carrier, a glass carrier and an activated carbon carrier; and the anti-aging auxiliary agent is a combination of an amine anti-aging agent, a phosphite antioxidant and an asymmetric hindered phenol antioxidant. The composite material disclosed by the invention has good thermo-oxidative aging resistance
