| titleOfInvention | A green production process of polyimide resin |
| abstract | The invention discloses a green production process for polyimide resin, which is characterized by comprising the following steps: preparation of bio-based diamine: preparing rosin acid into acrylic pimaric acid, chlorinating the acrylic pimaric acid, mixing with ammonia water reaction, the obtained solution is dried and added to tetrahydrofuran solution, and reduced with a reducing agent to obtain propylene pimaric acid diamine; bio-based diamine is dissolved in a polymerization solvent, and bio-based dianhydride is added in batches to stir to form a clear solution; the obtained solution Transfer to a light-proof container, add photoinitiator and antioxidant to obtain a uniform mixture; coat the uniform mixture on the polished tinplate, and put it in a UV box for UV curing. In the green production process of the polyimide resin of the invention, the bio-based polyimide is obtained by reacting the bio-based diamine with the bio-based dianhydride, and has excellent thermal and mechanical properties and good hydrophobicity. |
