| titleOfInvention | A kind of rigid polyimide foam and its preparation method and application |
| abstract | The invention provides a rigid polyimide foam and its preparation method and application, belonging to the field of polymer materials. The rigid polyimide foam has a structure shown in formula I. The polyimide foam prepared by the invention has high compression strength, excellent comprehensive mechanical properties, low apparent density and small dead weight, is convenient for transportation and construction, and can be used as a lightweight material. At the same time, the polyimide foam has excellent thermal stability and heat insulation performance, and can be used at high temperatures. The polyimide foam of the present invention has the characteristics of good thermal stability, high compressive strength, low density, and small dead weight, and can be used as structural materials in many high-tech fields such as aerospace, military ships, energy, and high-speed rail vehicles. Broad application prospects. |
