摘要(Abstract)：
为研制外观饱满的长储存期包装型乳化炸药产品，选取公司当前自然储存性能最好的包装型乳化炸药产品配方作为参考，在此配方基础上，通过试验不同种类乳化剂及乳化剂复配比例制得相应的乳胶基质，并采用物理敏化为主、化学敏化为辅的复合敏化工艺，制得相应的包装型乳化炸药。采用高低温循环试验与水溶值测试结合的方法评判各配方乳化炸药产品的储存稳定性。试验结果表明：高分子乳化剂LZ2832制备的乳化炸药稳定性能优于高分子乳化剂EPE-3002制备的乳化炸药，复合乳化剂中乳化剂Span80∶乳化剂LZ2832=1∶9含量配比时制备的乳化炸药稳定性能最好，可经受至少40个高低温循环试验，预计此配方包装型乳化炸药产品可自然存储24个月以上。炸药敏化采用基质质量1.2%的空心玻璃微球先进行物理敏化，降温到50～55℃时采用基质质量0.2%的促进剂2和基质质量0.3%的敏化剂再进行化学敏化，炸药敏化后效作用明显，最终密度控制在1.05～1.10 g/cm~3。进行生产线上批量生产试验验证，验证结果与实验研究结果一致，成功研制出外观饱满富有弹性的长储存期包装型乳化炸药产品，其自然储存12个月时，炸药性能仍保持稳定，爆速4500 m/s以上，猛度16 mm以上，殉爆距离6 cm以上。
