| titleOfInvention | Preparation method and application of transparent high-temperature-resistant polyarylate/polycarbonate alloy ester exchange reaction inhibitor |
| abstract | The invention discloses a transparent high-temperature-resistant polyarylate polycarbonate alloy ester exchange reaction inhibitor, which mainly comprises stannous hydroxy phosphate or a mixture of the stannous hydroxy phosphate and stannous pyrophosphate. Adding stannous chloride and deionized water into a reaction container, stirring and dissolving, dropwise adding a metered alkali solution to generate white stannous hydroxide precipitate, dropwise adding a metered dilute phosphoric acid solution or pyrophosphoric acid solution, heating to 50-100 ℃ after all the stannous hydroxide precipitate and pyrophosphoric acid solution are dropwise added, stirring and reacting for 1-2 hours, heating and stirring to react at a controlled temperature of 25-100 ℃, finishing the reaction, cooling, filtering, washing a filter cake with deionized water until no chlorine ion exists, and drying at 80-220 ℃ for 6-12 hours to prepare the white ester exchange reaction inhibitor. The inhibitor can improve the transparency and high temperature resistance of the PAR/PC blended plastic alloy, so that the heat resistance grade of the PAR/PC alloy is in direct proportion to the PAR content. |
