The invention discloses a method for preparing modified piperylene petroleum resin by using a composite catalyst, which comprises the following steps: mixing aluminum nitrate and anhydrous methanol, adding water and expanded graphite for impregnation, dripping ammonia water, stirring, sonicating and standing , after washing, filtration and activation, add in sodium carbonate aqueous solution for dipping, drying and roasting to obtain material A; under the protection of argon, mix anhydrous aluminum trichloride and xylene, add to material A, heat to reflux and stir , after filtering, washing and drying, mixed with phosphoric acid and SbCl to obtain a composite catalyst; using cyclohexane as a solvent, using the composite catalyst as a catalyst, using piperylene raw material, styrene, 2-methyl-1-butene and Myrcene is a monomer to carry out polymerization reaction, and after post-treatment, it is mixed with antioxidant 1520, light stabilizer Tinuvin 622LD, antioxidant DTDTP, expandable graphite, molybdenum trioxide, N-phenyl-α naphthylamine, at 160- Stir at 180°C and cool. |
