| abstract |
The invention discloses a thermoplastic resin composition, which comprises the following components in parts by weight: 30-80 parts of polycarbonate; 5-50 parts of polyester; 2-25 parts of impact modifier; 0.5 parts of boehmite ‑20 parts; the average particle size of the boehmite is 0.01-10 microns, and the content of Fe element is not more than 100 ppm. On the one hand, by controlling the Fe element content of boehmite, the boehmite maintains a cubic shape as a whole, but each surface of the cube is not smooth, showing a rough karst-like cliff shape, which has a great influence on the glossiness. On the other hand, the control of Fe element content avoids obvious degradation of PC polyester alloy; and the particle size range is controlled to enhance the extinction performance of boehmite. The thermoplastic resin composition of the present invention has a good matte effect. |
