| titleOfInvention | Polyimide modified polyisocyanurate foam and preparation method thereof |
| abstract | The invention discloses a polyimide modified polyisocyanurate foam material and a preparation method thereof. A polyimide precursor prepared by esterification reaction of aromatic dianhydride and aromatic diamine with fatty alcohol is compounded with polyester polyol, polyether polyol, a surfactant, a foaming agent, a catalyst, and the like to form a foam combination solution, the solution chemically reacts with polyisocyanate to foam, and then the polyimide modified polyisocyanurate foam is endued with properties such as high-temperature resistance and flame retardance. The modified polyisocyanurate foam material comprises (1) the foamable polyimide precursor, (2) benzoic anhydride polyester and sucrose polyether polyol, (3) a polyisocyanate curing agent, and (4) an organosilicon foam stabilizer, the organic fluorinated surfactant, the trimerization catalyst and the foaming agent. According to the foam material and the preparation method, a one-step foaming technology is adopted, and the technology is simple and convenient and low in cost; and the foam is temperature-resistant, flame-retardant and low in smoke density, so that the popularization and application are facilitated. |
