Increasing the hydrophobicity of ammonium nitrate is of great significance for its application as commercial explosives. In this article, a surface functionalized ammonium nitrate with enhanced water‐resistance property was demonstrated using a new hydrophobic coating agent. Structural properties and thermal stability of the prepared samples were investigated by powder X‐ray diffraction, scanning electron microscopy and differential scanning calorimetric analysis. Fourier‐transform infrared spectroscopic results show that a uniform hydrophobic layer is successfully coated on the surface of ammonium nitrate prills. Surface coated ammonium nitrate shows excellent stability in aqueous environment with effective detonation property compared to commonly used ammonium nitrate fuel oil (ANFO) explosives. Thus, our surface modified ammonium nitrate could serve as a potential explosive for watery hole blasting operations.

具有增强的耐水性的表面功能化硝酸铵小球：表征及其作为商业炸药的应用

提高硝酸铵的疏水性对其作为商业炸药的应用具有重要意义。在本文中，使用新型疏水性涂层剂证明了具有增强的耐水性的表面功能化硝酸铵。通过粉末X射线衍射，扫描电子显微镜和差示扫描量热分析研究了所制备样品的结构性质和热稳定性。傅里叶变换红外光谱结果表明，均匀的疏水层已成功涂覆在硝酸铵小球的表面。与常用的硝酸铵燃料油（ANFO）炸药相比，表面涂覆的硝酸铵在水环境中显示出出色的稳定性，并具有有效的爆炸特性。从而，
