Abstract:
Provided are a polycarbonate composite material, a preparation method therefor, and use thereof. The polycarbonate composite material comprises, in parts by weight: 30-90 parts of polycarbonate, 0.5-5 parts of an amino-containing compatilizer, 2-10 parts of a plasticizer, 2-4 parts of a phosphorus-based flame retardant, and 2-8 parts of a silicon-based flame retardant. The amino-containing compatilizer includes a nylon compatilizer. The plasticizer includes a plasticizer containing an m-benzene structure. According to the polycarbonate composite material, the specific type of compatilizer and plasticizer are added, and meanwhile, the phosphorus-based flame retardant and the silicon-based flame retardant synergistically retard flame, such that the polycarbonate composite material has excellent flame retardance, low smoke density and smoke release amount, low heat release rate and low smoke toxicity while taking the mechanical property into consideration, and thus is suitable for the fields of rail transit, aerospace, and the like.
