| titleOfInvention | Transparent film-level poly carbonate (PC)/polyester alloy material and preparation method thereof |
| abstract | The invention relates to the field of polymer alloy materials, in particular to a poly carbonate (PC)/polyester alloy material and a preparation method thereof. The transparent film-level poly carbonate (PC)/polyester alloy material comprises the following raw materials in part by weight: 20 to 50 parts of dihydric alcohol, 20 to 50 parts of dicarboxylic acid, 0.01 to 0.2 part of condensation catalyst, 30 to 80 parts of polycarbonate PC, 0.01 to 0.05 part of ester exchange catalyst, 0.1 to 0.5 part of antioxidant and 0.5 to 5 parts of heat stabilizer. The method for preparing the transparent film-level PC/polyester alloy material comprises the following steps of: adding the polycarbonate PC in the later period of the condensation of synthetic polyester, and performing ester exchange reaction with the polycarbonate PC while the polyester is subjected to the condensation. By the transparent film-level PC/polyester alloy material, the compatibility of the PC and the polyester and the stability of melts are improved greatly, so that the light transmittance of a transparent film is more than 85 percent, the transparent film is high in folding endurance and toughness, and the production cost is reduced. |
