| titleOfInvention | A kind of modified polycarbonate composition and preparation method thereof |
| abstract | The invention discloses a modified polycarbonate composition and a preparation method thereof. The modified polycarbonate composition comprises the following components: PC (polycarbonate); PBT (polybutylene terephthalate) ; Surface modified talcum powder; Rare earth metal compounds; Other additives. The preparation method is as follows: weigh PC and PBT according to the weight ratio and mix them in a high-speed mixer for 3 minutes. After mixing evenly, add them to the twin-screw extruder at the main feeding port of the first section; then add rare earth metal compounds, surface modified talcum powder and other additives are added at the main feeding port of the first section of the twin-screw or at the side feeding port of the third section; after melt extrusion, granulation and drying, the modified polycarbonate composition is obtained. The polycarbonate composition prepared by the invention has good high-temperature hydrolysis resistance and good mechanical properties, and can be used as a substitute for metal materials in some occasions. |
