The invention relates to a high thermal conductivity, antibacterial and weather-resistant PC/AS composite material and its preparation method. The composite material is prepared from the following raw materials in parts by mass: 40 to 60 parts of polycarbonate resin, 5 to 30 parts of acrylonitrile-styrene copolymer, 5 to 15 parts of acrylic impact modifier, 1 to 5 parts of flow aid, 5 to 30 parts of flaky thermal conductive filler, 1 to 10 parts of spherical thermal conductive filler, 0.1 to 5 parts of coupling agent, 0.1 to 2 parts of antibacterial agent, 0.1 to 1 part of dispersant, 0.5 to 4 parts of color sand, 0.5 to 4 parts of primary antioxidant, 0.1 to 0.5 parts of auxiliary antioxidant, and 0.1 to 1 part of lubricant. The composite material integrates excellent thermal conductivity, antibacterial performance and weather resistance. The preparation method features reasonable process design and simple operation, which is suitable for large-scale commercial production.
