Embodiment 1
[0016] The preparation steps of an additive for reducing the slow cook-off response of solid motors are as follows:
[0017] (1) Add 0.5g polyacrylic acid resin (Lianyungang Iodine Factory), 0.9g hydroxypropyl methylcellulose (Dow Chemical Company) and 0.3g diethyl phthalate (Shanghai Huadong Reagent Company) to 40mL In water ethanol, stir for 5min at a stirring rate of 500r / min to obtain a mixed solution;
[0018] (2) The mixed solution is spray-dried and granulated first, and then passed through 120-mesh and 200-mesh sieves respectively to obtain spherical granule additives with a particle size of 120-200 mesh.
[0019] Mix the additive prepared in this example with the HTPB / AP / Al solid propellant at a mass ratio of 2:100, and after mixing evenly, add it to a solid motor of φ60mm×140mm and solidify to obtain HTPB containing the additive / AP / Al solid motor charge. The HTPB / AP / Al solid motor charge without additives has the same process steps and conditions as the HTPB / AP / Al...
Embodiment 2
[0022] The preparation steps of an additive for reducing the slow cook-off response of solid motors are as follows:
[0023] (1) Add 0.2g polyacrylic acid resin (Lianyungang Iodine Factory), 0.8g hydroxypropyl methylcellulose (Dow Chemical Company) and 0.2g diethyl phthalate (Shanghai Huadong Reagent Company) to 40mL In water ethanol, stir at a stirring rate of 600r / min for 5min to obtain a mixed solution;
[0024] (2) The mixed solution is spray-dried and granulated first, and then passed through 120-mesh and 200-mesh sieves respectively to obtain spherical granule additives with a particle size of 120-200 mesh.
[0025] Mix the additive prepared in this example with the HTPB / AP / Al solid propellant at a mass ratio of 5:100, and after mixing evenly, add it to a solid motor of φ25mm×100mm and solidify to obtain HTPB containing the additive / AP / Al solid motor charge. The HTPB / AP / Al solid motor charge without additives has the same process steps and conditions as the HTPB / AP / Al...
