NON-HALOGEN FLAME RETARDANT POLYCARBONATE RESIN COMPOUND HAVING IMPROVED INFRARED TRANSMISSIVITY

摘要

A non-halogen flame retardant polycarbonate is provided to ensure excellent infrared transmission and non-halogen fire retardant characteristic by mixing aromatic phosphate and fluorinated olefin with polycarbonate. A flame retardant thermoplastic resin composition comprises (A) a polycarbonate resin, (B) aromatic phosphate, and (C) fluoroolefin. The composition contains (A) 83 to 93% by weight of the polycarbonate resin, (B) 6 to 17% by weight of aromatic phosphate, and (C) 0.08 to 0.3% by weight of fluoroolefin. The polycarbonate resin is a compound prepared by reacting a divalent phenolic compound with a phosgene or carbonic acid diester and containing no halogen. The aromatic phosphate is selected from aromatic monophosphate, aromatic diphosphate and a mixture thereof.
