摘要
综述了高残炭酚醛树脂:硼改性、钼改性、芳基酚改性及硅氮烷改性酚醛树脂,酚三嗪树脂,苯并恶嗪树脂的研究进展。上述改性后的酚醛树脂,耐热性显著提高。这些研究为耐烧蚀材料的应用提供了理论依据,为新一代的高残炭树脂的开发提供了方向。最后指出酚醛树脂在今后的耐烧蚀材料领域仍然会发挥重要的作用。
In this paper,progress in high char yield phenolic resins such as the phenolic resins modified by organic boron,molybdenum,aryl phenols and silazane,phenolic-triazine resins and polybenzoxazines was reviewed.The results showed that the heat-resistance of the modification phenolic resins was improved remarkably.These studies provided theoretical evidence for the application of ablation resistant materials and direction for the development of new high char yield resins.Phenolic resins would still play an impo...
