POLYCARBONATE COMPOSITION AND PREPARATION METHOD AND APPLICATION THEREOF

摘要

Disclosed in the present invention is a polycarbonate composition, comprising the following components in parts by weight: a. 86-99.9 parts polycarbonate; and b. 0.1-14 parts flame retardant; the sum total parts by weight of the two components a and b is 100 parts. By means of selectively adding to the polycarbonate composition formulation perfluorinated alkyl acid and derivatives thereof, the amount thereof being ≤ 100 ppm based on the total weight of the polycarbonate composition, and because the fluorinated alkyl acid and the derivatives thereof have low aqueous solubility and do not easily lose effectiveness in the presence of water, the present invention can significantly improve the mechanical performance and flame retardancy of the polycarbonate composition in high temperatures and high humidity, the flame retardancy thereof reaching 1.5 mm/v-zero, and the mechanical performance and flame retardancy remaining high in 85% humidity and 85°C temperature; the present invention is particularly suited for use in the charger and battery forming industry.
