为研究黏结剂对可燃传火管性能的影响,分别采用惰性黏结剂、含能黏结剂、惰性/含能混合黏结剂和惰性黏结剂/RDX混合物,以卷制工艺制备了4种可燃传火管,测试了其力学性能和定容燃烧性能.结果表明,与制式可燃传火管相比,全部采用含能黏结剂可使可燃传火管的定容燃烧灰分降低69.0%,但拔断力、压缩力和耐压强度分别下降了52%、68%和60%;采用惰性黏结剂/RDX(质量比90∶10)混合物时,可燃传火管的力学性能基本不变,定容燃烧灰分降低12.2%;采用惰性/含能混合黏结剂(质量比为50∶50)时,可燃传火管的燃速和燃烧完全性得到改善,力学性能下降幅度较小.%To study the effect of adhesives on the properties of combustible igniter tube,four kinds of combustible igniter tubes were prepared through roll-forming process by inert adhesive, energetic adhesive, inert/energetic mixed adhesive and inert adhesive/RDX mixture, respectively, their mechanical properties and constant-volume combustion performance were tested.The results show that compared with the standard combustible igniter tube, the combustible igniter tube with energetic adhesive can make the constant-volume combustion ash reduce by 69.0%, but drawing force, compressing force and pressure resistant strength are decreased by 52%,68% and 60%, respectively.When the inert adhesive/RDX mixture (mass ratio of 90∶10) is used, the mechanical properties of combustible igniter tube are basically unchanged and the constant-volume combustion ash reduces by 12.2%.When the inert/energetic (mass ratio of 50∶50) mixed adhesive is used, the burning rate and combustion completeness of combustible igniter tubes are improved, and the mechanical properties decrease slightly.
