Zusammenfassung:The invention discloses a perfume-resistant and floral-water-resistant PC/ABS (polycarbonate/acrylonitrile-butadiene-styrene) composite material for automotive interiors and a preparation method of the perfume-resistant and floral-water-resistant PC/ABS composite material. 20 to 35 parts of ABS resin; 5 to 10 parts of PET (Polyethylene Terephthalate); 0-5 parts of a compatilizer; 0.1-1 part of a light stabilizer; 0.1 to 2 parts of an antioxidant; 0.1 to 0.5 part of a lubricant; the viscosity of the PET resin is 0.5-0.8, the content of terminal hydroxyl groups is 30-40 mol/t, and the content of diethylene glycol is less than or equal to 0.8%. By adding a small amount of PET resin with specific viscosity, the perfume resistance and the floral water resistance of the PC/ABS are improved. PET molecular chains contain ester groups and terminal hydroxyl groups, PET resin with specific viscosity and terminal hydroxyl group content can be well compatible with PC and can be fully dispersed in a PC/ABS alloy, meanwhile
