氨酚醛树脂投料比与其热解性能、烧蚀性能的关系

Effect of Formaldehyde/Phenolic(F/P) Ratio on Pyrolysis Behavior and Ablation Properties of Ammonia Catalyzed Phenolic Resin

利用裂解气相色谱—质谱联用法和热天平法研究了不同投料比的氨酚醛树脂的热解性能,并利用扫描电子显微镜研究了其复合材料的烧蚀形貌,从而得到了氨酚醛的投料比与热解性能及烧蚀性能的关系,证明酚醛树脂合成甲醛和苯酚的投料比低时(1.18),其热性能和烧蚀性能较差。

This paper desribes the pyrolysis behavior and the ablation properties of ammonia catalyzed phenolic （ACPR） by Pyrolysis-Gas Chromatograhy Mass （PyGC-MS）, TGA and SEM. The results show that the ratio of the formaldehyde/phenolic（F/P） has a distinct influence on the pyrolysis behavior and ablation properties. The lowest F/ P-ratio （ 1.18 ） the resin has , the worst property of thermal-resistant and ablation property the composite possesses.
