    摘要： The present invention discloses a polycarbonate composite material, which comprises 30-80 parts by weight of a polycarbonate; 5-40 parts by weight of an ABS; 5-80 parts by weight of a filler; wherein, based on a total weight of the polycarbonate composite material, a weight content of iron element is 0.1 ppm-50 ppm, and a weight content of copper element is 0.01 ppm-20 ppm. It has been surprisingly found in the present invention that controlling a content of iron element in the composite material between 0.1 ppm and 50 ppm and a content of copper element between 0.01 ppm and 20 ppm by adding a trace amount of iron element and copper element in the composite material, can not only avoid a pretreatment for filler powders, but also stabilize alkaline ions in a system and reduce a darkened color and a property damage caused by an introduction of a screw and other metals, so that the polycarbonate composite material prepared has an obviously improved impact strength, an obviously improved flexural and an obviously improved molding tenacity, and also it can combine the rigidity brought by the filler, having excellent molding use stability and excellent color stability.

    摘要： The present invention discloses a polycarbonate composition, which comprises following components in parts by weight: a. 29.9-79.9 parts of a polycarbonate; b. 8.1-50.1 parts of a graft copolymer; c. 4.8-24.8 parts of a fire retardant; and d. 0-9.9 parts of other aids; wherein a sum of parts by weight of the four components a, b, c and d is 100, and a content of phosphorus oxychloride based on a total weight of the polycarbonate composition is less than or equal to 80 ppm and greater than or equal to 0.1 ppm. When a tested content of phosphorus oxychloride in a polycarbonate composition formula of the present invention, based on the total weight of the polycarbonate composition does not exceed 80 ppm, phosphorus oxychloride remained in a trace level can be advantageous for generation of a stable compound such as phosphoric acid and a polymetaphosphate, can further facilitate generation of a char layer, can improve desperation of a phosphorus-containing fire retardant in the composition at the same time, can finally obviously improve a fire resistance and a melt stability of the polycarbonate composition, and is particularly suitable for an occasion with relatively high requirements for an operating environment.
