摘要:
结合超临界流体发泡技术在微孔聚合物中的应用，制备了具有多孔结构的高能迫击炮附加药盒材料。为保证附加药盒材料具有较好的耐热性，采用耐热性炸药RDX为含能组分，惰性聚合物为黏结剂，对材料内部形貌特征、能量、燃尽性、燃烧速度、耐热性和吸湿性进行了测试。结果表明：经超临界CO2发泡的附加药盒材料内部为疏松多孔结构，微孔尺寸小于1 μm；高RDX含量的附加药盒材料具有较高的能量，含70%（质量分数）RDX的附加药盒材料火药力达到750 J/g； RDX质量分数为50%时，有少量无害残渣，而RDX质量分数为60%以上时，附加药盒材料洁净燃烧；由于疏松多孔结构，微孔附加药盒材料的燃烧速度较传统发射药高；并且附加药盒材料具有较好的耐热性和防潮性。
Abstract:
According to the supercritical fluid foaming technology in the preparation of microporous polymer, an additional charge kit material with porous structure used in high energy mortar was prepared. In order to maintain a good property of heat resistance, RDX was used as the energetic material and inert polymer was used as the binder. The inner porous structure, energy, combustion, burning rate, heat resistance and moisture absorption of this material were studied. The results indicate that after supercritical CO2 foaming the internal structure of the kit was porous with micropore size of less than 1 um. The kit with high RDX content has high energy, and the additional kit gunpowder force was 750 J/g when the mass fraction of RDX reaches to 70%. There is little poisonless burning residue with the RDX content of 50% (mass fraction). And the clean combustion occurs when the mass fraction of RDX is above 60%. Because of the porous structure, burning rate of this material is higher than conventional propellents. This material performed well in heat resistance and moisture absorption tests.
