Antibacterial halogen-free flame-retardant PC/ABS composite material with high ball pressure temperature and preparation method thereof

The invention discloses an antibacterial halogen-free flame-retardant PC/ABS composite material with high ball pressure temperature. The composite material mainly comprises the following components in parts by mass: 59-88 parts of PC, 520 parts of ABS, 4-12 parts of an organophosphorus flame retardant, 2-5 parts of a flexibilizer, 0.4-1 part of an antibacterial agent, 0.2-0.5 part of an anti-dripping agent, 0.2-1 part of a dispersing agent and 0.2-1 part of an antioxidant. The halogen-free flame-retardant PC/ABS composite material is good in antibacterial property, high in ball pressure resistant temperature, good in flame retardant property and white in color, various bright-colored products can be manufactured by adding the coloring agent, no halogen flame retardant is adopted, the flame retardant grade of the material is high, cost is low, smell is small, and large-area application and popularization are facilitated. The invention also discloses a preparation method of the composite material. The preparati
