一种聚碳酸酯组合物及其制备方法
摘要：
本发明公开了一种聚碳酸酯组合物及其制备方法，按重量份计，包括以下组份：35份-70份的聚碳酸酯；0份-45份的接枝共聚物；8份-30份的阻燃剂；5份-45份的矿物填料；其中，基于聚碳酸酯组合物的总重量，镍元素的重量含量为1ppm-100ppm。本发明通过在聚碳酸酯组合物中添加具有较低可溶性镍含量的含镍化合物以及减少或者避免其它含镍化合物的加入，将聚碳酸酯组合物中镍元素的含量控制在1-100ppm范围内，可以使制得的聚碳酸酯组合物在85℃烘烤200h后的色差值小于8，颜色等级3级或以上，具有优良的颜色稳定性。
摘要（英）：

The invention discloses a polycarbonate composition and a preparation method thereof. The polycarbonate composition comprises, by weight, 35-70 parts of a polycarbonate, 0-45 parts of a graft copolymer, 8-30 parts of a flame retardant and 5-45 parts of a mineral filler. Based on the total weight of the polycarbonate composition, the nickel weight content is 1 ppm to 100 ppm. Through use of the nickel-containing compound having low soluble nickel content in the polycarbonate composition and reduction or prevention of other nickel-containing compounds, the nickel content of the polycarbonate composition is controlled in a range of 1-100 ppm so that the prepared polycarbonate composition has a color difference value of less than 8 after being baked at 85 DEG C for 200h, a color level of 3 orhigher and excellent color stability.
