摘要:
为了降低超细高氯酸铵(AP)的机械感度,以十八烷胺为包覆剂,经气流粉碎工艺,制备了超细AP包覆粒子。通过对超细AP包覆粒子进行粒度分析、SEM分析、DSC分析及感度检测,研究了超细AP包覆粒子的包覆效果、热分解特性及感度特性。试验结果表明:超细AP包覆粒子,粒度为D50=5.8 μm,表面有包覆层存在;超细AP包覆粒子的感度,与超细AP样品相比,当包覆剂质量分数为1% 时,撞击感度降低31.2%,摩擦感度降低12.0%;当包覆剂质量分数为3%时,撞击感度降低34.5%,摩擦感度降低22.0%,且包覆剂用量越大,撞击感度和摩擦感度越低;但包覆剂对AP的热分解会产生一定的负面影响,质量分数应≤1%。
Abstract:
In order to reduce the mechanical sensitivity of AP superfine powder, octadecylamine was used as the coating agent, and AP-coated superfine particles were prepared by jet mill. The coating effect, thermal decomposition characteristics and sensitivity characteristics of AP-coated superfine particles were studied by particle size analysis, SEM analysis, DSC analysis and sensitivity testing. Experimental results show that particle size of AP-coated superfine particles is D50 = 5.8μm, with a coating layer present on the surface. Compared with the pure AP superfine particles, when the mass fraction of coating agent is 1%, the impact sensitivity of AP-coated superfine particles is reduced by 31.2% and friction sensitivity is decreased by 12.0%. While when the mass fraction of coating agent is 3%, the impact sensitivity of AP-coated superfine particles is reduced by 34.5% and friction sensitivity is decreased by 22.0%. In addition, the greater the coated dosage, the lower the impact sensitivity and the friction sensitivity. However, coating agent has some negative impacts on the thermal decomposition of AP, and thus its dosage should be controlled less than 1% (mass fraction).
