CL-20基挤注型传爆药药浆流变特性研究

通过差示扫描量热仪（DSC）测试,六氮杂异伍兹烷（CL-20）与聚叠氮缩水甘油醚（GAP）具有较好的内相容性;利用R/S流变仪分别研究了GAP与三乙酸甘油酯（GT）不同增塑比黏度、CL-20与GAP不同混合比例、不同温度、不同粗细比例的传爆药药浆黏度特性;研究结果发现,GAP与三乙酸甘油酯（GTA）不同增塑比例（3∶1、3∶2、3∶3）的混合黏度分别为0.85 Pa·s、0.45 Pa·s、0.30 Pa·s;CL-20固含量81%的粗（d50〈200μm）细（d50〈5μm）粒径传爆药药浆的黏度分别为10 Pa·s、30 Pa·s;不同粒度级配的药浆粗细比例（1∶2）与（2∶1）的药浆黏度相差不大;粗细比例（1∶2）CL-20固含量79%、80%、81%的药浆黏度依次升高。

Rheological Properties of Extruded Booster Charge Slurry Based on CL-20

Hexaazaisowurtzitane （CL-20） has a good compatibility with glycidyl azide polymer （GAP） by differential scanning calorimeter （DSC） method. R/S rheological instrumentation was employed investigate the viscosity of different plasticization ratios of GAP and glyceryl triacetate（GT）. The viscosity of different proportions, temperatures and particle size ratio of CL-20-based slurry were investigated too. Results show that the viscosity of different plasticization ratios of GAP and GT（3： 1, 3： 2, 3： 3）are 0.85 Pa · s, 0. 45 Pa·s and 0.30 Pa · s, respectively. The viscosity of different particle size （ d50 〈 200 μm, ds0 〈 5 μm） 81% CL-20 of explosive slurry are 10 Pa ·s and 30 Pa · s respectively. However, the viscosity of large and small particle size ratio （ 1 ： 2 ） and （ 2 ： 1 ） explosive slurry is nearly the same. The viscosity of 77 % , 79% and 81% CL-20-based slurry （ large, small particle ratio 1 ： 2） were increased successively.
