摘　　要：为优化JNJ-A型胶凝剂的制备工艺,保证胶体推进剂的产品质量,采用正交试验研究了JNJ-A型胶凝剂合成碱化工艺参数对产品性能的影响。依据粘度、透光度等性能指标筛选出较佳胶凝剂制备碱化工艺条件为:碱液浓度22%,碱液用量35_(wt原料_%,稀释剂用量为原料质量的26倍,碱化温度1℃,碱化时间70 min,得到了粘度值32 000 mPa·s,透光度74%的合格JNJ-A型胶凝剂产品,确定了各个碱化工艺参数对胶凝剂性能影响的先后顺序为:碱化时间>碱液浓度>碱液用量>稀释剂用量>碱化温度。In order to optimize the synthesis process of JNJ-A gellant and ensure the quality of final gelled propellant, orthogonal design was employed to investigate the influences of alkalization process on the performance of JNJ-A gellant. The optimal alkalization process was confirmed via comparing the viscosity and transparence, and the regular products which had the viscosity of 32 000 mPa. s and the transparence of 74% were achieved under the alkali concentration of 22%, the alkali quantity of 35% to the materials, the solvent quantity of 26 times to the materials, the alkaliza- tion temperature of 1℃ and the alkalization time of 70 min. The sequence of the influence of the al- kalization process parameters on the gellant properties was determined. It is alkalization time〉alkali concentration〉quantity of alkali〉quantity of solvent〉alkalization temperature.
