Toughening agent with core-shell structure, preparation method and application of toughening agent in preparation of oil-resistant high-toughness PC alloy

The invention provides a core-shell structure toughening agent, a preparation method and application of the core-shell structure toughening agent in preparation of an oil-resistant high-toughness PC alloy, the core-shell structure toughening agent comprises a shell layer of polyvinylpyrrolidone ketal with aryl and a core of acrylate rubber, the preparation raw materials comprise polyvinylpyrrolidone, an aromatic alcohol compound and an acrylate monomer. The synthesized core-shell structure flexibilizer and organic peroxide are introduced into PC resin, the extrusion temperature and the injection molding temperature in the production process are controlled, so that the shell of the flexibilizer is crosslinked, an oil-resistant and high-toughness PC alloy product is prepared, and the PC alloy has lasting fragrance and is high in toughness. And after the performance is improved, the heat resistance and flame retardance of the PC material are well reserved. 本发明提供一种核壳结构增韧剂和制备方法及其在制备耐油高韧PC合金中的应用，所述核壳结构增韧剂包含带有芳香基的聚乙
