| 摘 要： | 采用X射线电子能谱法(XPS)、傅里叶变换红外光谱法(FTIR)和粘度测试等实验手段，确定了含硼HTPB富燃料推进剂工艺恶化的主要原因，证实硼粉表面杂质H3BO3，B2O3与HTPB中羟基反应生成硼酸酯，引起凝胶化反应，是导致B／HTPB不相容的根本原因。并利用交联反应出现凝胶的临界反应程度Pc理论解释了其作用机理。

| Abstract: | By X-ray photoelectron spectroscopy (XPS), Fourier transform infra-red spectroscopy (FTIR) and viscosity measurement, it is affirmed that the poor processability in boron-contained HTPB propellants is originated from the gelation between the HTPB and boron surface impurities, namely boric acid and boric oxide, so as to form borate. The theory of critical reaction degree is used to explain the mechanism of the deteriorated processability. |
