The invention belongs to the technical field of polycarbonate composites, and particularly discloses a flame-retardant, high-transmittance and weather-proof polycarbonate composite used for an LED lampshade and a preparation method. The polycarbonate composite is prepared from raw materials including, by weight, 100 parts of polycarbonate, 0.2-0.6 part of copolymerized organic siloxane microspheres, 3-8 parts of organic nano-montmorillonite, 0.5-1 part of weather-proof agent, compatilizer and 0-2 parts of other auxiliaries. The prepared flame-retardant, high-transmittance and weather-proof polycarbonate composite has excellent chemical performance and processing performance, has the advantages of high transmittance, high flame retardance, excellent weather resistance and the like, can meet requirements of LED illumination lampshades, and is simple in process and beneficial to wide application and popularization.
