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.
