摘　　要：为了研究2，4-二羟基苯甲酸铅铜盐（Pb／Cu-SDHB）单独或与其它催化剂复合后对含Al粉和黑索今（RDX）改性双基（AI／RDX-CMDB）推进剂燃烧I生能的影响，采用吸收．压延方法制备了推进剂样品，用靶线法测试了推进剂燃速。结果表明：Pb/Cu-sDHB能有效调节推进剂燃烧性能，显著提高了A1／RDX-cMDB推进剂的燃速，并明显降低了压强指数；3．0％Pb／Cu-SDHB与0．65％炭黑复合后使A1RDX-cMDB推进剂在10~15MPa的压强指数降低至．0．1，10MPaT燃速黜0mm／s。In order to investigate the effects of lead/cupric salt of 2,4-dihydroxybenzoate（Pb/Cu-SDHB）itself, or composite with other catalysts on the combustion properties of AI/RDX-CMDB propellant, the propellant samples were prepared through a solventless extrusion technique, as well as the burning rate of propellants were measured by stand burner method .The results showed that Pb/Cu-SDHB could increase the burning rate and reduce the pressure exponent of AI/RDX-CMDB propellant notably. When 3.0% Pb/Cu-SDHB composited with 0.65% carbon, the pressure exponent of AI/RDX-CMDB propellant reduced to -0.1 under 10~15MPa, and the burning rate at 10MPa would exceed 20mm/s.
