Polycarbonate Composition and Preparation Method Thereof |
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; andd. 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. |
