摘要:
因高氯酸钠NaClO4热分解的气相成分不含HCl气体且性能稳定，在低特征信号推进剂中有很好的应用前景。但NaClO4吸湿性较强，应用到推进剂中会导致推进剂工艺恶化，难以加工成型。为降低NaClO4的吸湿性，促进NaClO4在低特征信号推进剂中的应用，采用机械混合法制备了高氯酸钠/十八胺（NaClO4/ODA）复合物。通过扫描电子电镜（SEM）、傅里叶红外光谱仪（FT-IR）、拉曼光谱仪(Raman spectra)、X射线衍射仪、DSC-TG同步热分析仪、接触角测定仪和恒温恒湿试验,对样品的形貌、晶体结构、热分解性能、亲水性和吸湿性进行了表征。表征结果表明，ODA成功包覆到了NaClO4表面。在10 ℃、相对湿度30 %的条件下存放36 h后，原料NaClO4和NaClO4/ODA-复合物均不吸湿；在10 ℃、相对湿度40 %条件下存放60 h，原料NaClO4和NaClO4/ODA复合物均有不同程度的吸湿，包覆剂ODA质量分数1.0%的NaClO4/ODA复合物吸湿率比原料NaClO4降低63 %，说明包覆具有明显降低NaClO4吸湿性的作用。且防吸湿处理对NaClO4的放热量无影响。
Abstract:
The gas-phase products generated by the thermal decomposition of sodium perchlorate (NaClO4) do not contain HCl gas and have stable properties. Therefore, NaClO4 has great application prospects in making low characteristic signal propellants. However, NaClO4 has strong hygroscopicity, and its application in propellants can lead to deterioration of the propellant process, making it difficult to process and shape. In order to reduce the hygroscopicity of NaClO4 and promote its application in low characteristic signal propellants, sodium perchlorate/octadecylamine (NaClO4/ODA) composites were prepared by mechanical mixing method. The morphology, crystal structure, thermal decomposition performance, hydrophilicity, and hygroscopicity of the samples were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectrometer (FT-IR), Raman spectrometer, X-ray diffraction, DSC-TG synchronous thermal analyzer, contact angle analyzer, and constant temperature and humidity tests. The characterization results indicate that ODA has successfully coated the surface of NaClO4. After being stored at 10 ℃ and relative humidity of 30% for 36 h, both NaClO4 and NaClO4/ODA composites do not absorb moisture. After being stored at 10 ℃ and relative humidity of 40% for 60 h, both NaClO4?and NaClO4/ODA composites show varying degrees of moisture absorption. The moisture absorption rate of NaClO4/ODA composite with a mass fraction of 1.0% of the coating agent decreases by 63% compared to NaClO4, indicating that the coating has a significant effect on reducing the moisture absorption of NaClO4. And the anti moisture treatment has no effect on the heat release of NaClO4.
