The invention discloses a shading flame-retardant PC composite material and a preparation process thereof. Pollution caused by the petroleum-based material in the exploitation and preparation process is not avoided, organic strong base is used as a catalyst, dihydric alcohol is used for capturing carbon dioxide in a high-pressure environment, and the carbonic ester monomer is prepared; in addition, the variety of dihydric alcohol is strictly limited, 1, 4-cyclohexanediol with a carbocyclic structure and 3-aza-diol with a nitrogen element are used, and the nitrogen element and a rigid carbocyclic ring are introduced into the carbonic ester structure, so that the flame retardance and the mechanical property of the flame-retardant polycarbonate are enhanced. After the carbonic ester monomer is synthesized, the carbonic ester monomer is mixed with thiol with high chemical activity, and the shading flame-retardant PC material is finally prepared, has excellent mechanical strength and ultraviolet irradiation resist
