The invention discloses a phenolic-based renewable polymer material, a preparation method and a regeneration application thereof, which comprise the following steps: step 1, according to the molar ratio of phenolic hydroxyl groups to isocyanate groups (10-1): 1, taking a thermoplastic phenolic resin and an aromatic polyisocyanate compound; step 2, dissolving the thermoplastic phenolic resin taken out from the step 1 in an organic solvent, and stirring to obtain a phenolic resin solution; dissolving the aromatic polyisocyanate compound taken out in the step 1 in an organic solvent to obtain a polyisocyanate compound solution; and 3, mixing the phenolic resin solution with the polyisocyanate compound solution, and treating the mixed solution to obtain the phenolic-based renewable high polymer material. The high polymer material obtained by the invention has excellent heat resistance and mechanical properties. |
