氰酸酯树脂的改性（毕业论文） PAGE \* MERGEFORMAT37 氰酸酯树脂的改性 复材111班张鹏宇 摘要：氰酸酯树脂是有较大应用潜力和发展前景的一种热固性树脂，但脆性较大，韧性不高，所以有很大的改性必要性。本论文采用4-硝基邻苯二甲腈和双酚A溶于DMA，制备双邻苯二甲腈单体，利用核磁共振氢谱(1H-NMR)对双邻苯二甲腈的结构进行表征，采用示热失重分析仪（TGA）对聚合物的固化行为和耐热性能进行了测试分析。采用加热熔融共混树脂，探究多种比例共混树脂的性能。 探究双邻苯二甲腈单体的合成工艺并进行改进，得到合成双邻苯二甲腈单体的最佳条件，通过TGA测试得到双邻苯二甲腈改性氰酸酯的TGA图谱并进行分析，改善了氰酸酯树脂的耐热性。 关键字：氰酸酯树脂，双邻苯二甲腈，改性 Modified of cyanate ester resin Abstract: Cyanate ester resin is a thermosetting resin greater potential and development prospects, but brittle, toughness is not high, so there is a great necessity modified. In this paper, using 4-nitro-phthalonitrile and bisphenol A was dissolved in DMA, prepare a two-phthalonitrile monomer by proton nuclear magnetic resonance spectroscopy (1H-NMR) double phthalonitrile of structure characterization, using thermal gravimetric analyzer shows (TGA) on curing behavior and thermal properties of the polymers were tested. Using heat melt blending resin, explore various ratios blended resin performance. Inquiry synthesis of double phthalonitrile monomer and make improvements, to get the best conditions for the synthesis of double phthalonitrile monomer to obtain a two phthalonitrile modified isocyanate tested by TGA and TGA profiles analyze and improve the heat resistance of cyanate ester resin.
