摘要： The present invention discloses a polycarbonate composition, which includes the following components in parts by weight: a. 30-80 parts of a polycarbonate; b. 8-50 parts of a graft copolymer; c. 5-25 parts of a fire retardant; and d. 0-10 parts of other aids; wherein a sum of parts by weight of the four components a, b, c, and d is 100. A long-term thermal-oxidative aging property and a weathering property of the polycarbonate composition can be significantly improved when a total compounding amount of a transition element and an alkaline earth metal, which are added in a polycarbonate composition formula, based on a total weight of the polycarbonate composition is greater than or equal to 10 ppm and less than or equal to 600 ppm and a compounding molar ratio of the transition element to the alkaline earth metal is adjusted to 0.1-1; and the polycarbonate composition is particularly suitable for occasions with relatively high requirements for an operating environment.
摘要翻译：公开了一种聚碳酸酯组合物，其包含以下重量份的组分：a，30-80份聚碳酸酯，b，8-50份接枝聚合物，c，5-25份阻燃剂和d，0 -10份其他助剂; 其中a，b，c和d的四种成分的重量份之和为100份。在本发明中，当将基于聚碳酸酯组合物的总重量添加到聚碳酸酯组合物配方中的过渡元素和碱土金属的化合物总量选择为大于或等于10ppm且小于或等于等于600ppm，将过渡元素与碱土金属的复合摩尔比调节至0.1-1，可以显着提高聚碳酸酯组合物的长期热氧化老化性能和耐候性，聚碳酸酯组合物特别适用于高使用环境要求的场合。
