摘　　要：以2,4,6-三氨基嘧啶为三胺单体,经由聚酯铵盐前体粉末发泡合成了具有交联结构的聚酰亚胺泡沫。结果表明,三胺单体的加入对聚酰亚胺前体及其泡沫的化学结构和聚集态结构没有明显的影响。含2,4,6-三氨基嘧啶的聚酰亚胺泡沫材料的5%热失重温度均在520℃以上,且具有良好的耐燃烧性。随着三胺单体含量的增加,聚酰亚胺泡沫材料的力学性能和玻璃化转变温度得到提高。Taking 2,4,6-triaminopyrinide as triamine monomer, polyimide foams with cross-linked structures were prepared by foaming poly（ester-amine salt） precursor powders. The results show that the addition of triamine monomer has no obvious influences on chemical structures and aggregative states of polyimide precursors and the imidized products. Polyimide foams containing 2,4,6-triaminopyrimide has a 5% weight loss when the temperature is above 520 ~C and possesses excellent flame retarding property. With the increase of content of triamine monomer, the mechanical property of polyimide foams is improved, and the glass transition temperature of polyimide foams increases.
