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：30份-80份的聚碳酸酯；0份-50份的接枝共聚物；1份-30份的阻燃剂；1份-50份的矿物填料；其中，基于聚碳酸酯组合物的总重量，钙元素的重量含量为50ppm-300ppm。本发明通过在聚碳酸酯组合物中添加具有较低可溶性钙含量的含钙化合物以及减少或者避免其它含钙化合物的加入，将聚碳酸酯组合物中钙元素的含量控制在50-300ppm范围内，可以使制得的聚碳酸酯组合物不仅具有较高的冲击强度和较好的加工流动性满足各种成型制件的加工需求，且具有较高的光泽度，明显改善了聚碳酸酯组合物的表面质量。
摘要（英）：

The invention discloses a polycarbonate composition and a preparation method thereof. The polycarbonate composition comprises the following components in parts by weight: 30 to 80 parts of polycarbonate, 0 to 50 parts of grafted copolymer, 1 to 30 parts of fire retardant, and 1 to 50 parts of mineral filling material, wherein based on the total weight of the polycarbonate composition, the weight of calcium is 50 to 300 ppm. By adding calcium containing compounds with a low content of soluble calcium into the polycarbonate composition and reducing/avoiding the addition of other calcium containing compounds, the content of calcium in the polycarbonate composition is controlled in a range of 50-300 ppm; and the prepared polycarbonate composition has high impact strength and good processing fluidity, can meet the processing requirements of various moulded parts, and has high glossiness. The surface quality of the polycarbonate composition is obviously improved.
