摘要
以太安(PETN)为主体炸药、ATBC(乙酰柠檬酸三丁酯)为增塑剂、MVQ(甲基乙烯基硅橡胶)和RTV(室温硫化硅橡胶)为橡胶型胶粘剂,制备出一种片状橡胶炸药。采用非等温DSC(差示扫描量热)法表征了该橡胶炸药的内相容性,并对其拉伸性能和爆轰性能等进行了研究。结果表明:该橡胶炸药的内相容性良好,其拉伸强度(0.449 MPa)和断裂伸长率(38.6%)均满足应用要求;在装药密度为1.50 g/cm3、片状橡胶炸药厚度≥0.4 mm时,该橡胶炸药的爆轰能可靠持续的传爆。
With taian （PETN） as explosive subject, ATBC （acetyl tributyl citrate） as plasticizer, MVQ （methyl vinyl silicone rubber）and RTV （room temperature vulcanization silicone rubber） as rubber adhesives, a sheet of rubber-explosive was prepared. The inner compatibility of rubber-explosive was characterized by non-isothermal DSC （differential scanning calorimetry）, and its tensile properties and detonation properties were investigated. The results showed that the rubber-explosive had good inner compatibility, its tensile strength（0.449 MPa） and elongation at break （38.6%） could all satisfy the application requirements. The detonation of rubber- explosive could be reliably and continuously boosted when the charge density was 1.50 g/cm3, sheet thickness of rubber-explosive was not less than 0.4 mm.
