摘要 为提高模压可燃药筒的力学强度,同时改善其燃尽性,于某定型号产品配方基础上试制了含新型黏结剂CK及水性交联剂DZ的新型模压可燃药筒,并对黏结剂与交联剂配比、试样力学强度及燃烧性能等进行了研究。结果表明,黏结剂CK和交联剂DZ优化配比后的质量分数分别为12.0%和1.5%;新型模压可燃药筒抗拉强度和最大伸长率可达到36.7 MPa和7.0%,较传统试样分别提高了46.2%和42.9%;燃烧后,烘前及烘后平均残渣质量分别降低了55.07%和64.07%;此外,上炮试验中,射击后火炮膛内也无影响装填的残渣。新型黏结剂CK和水性交联剂DZ的引入有效地提高了模压可燃药筒的力学强度及韧性,且燃尽性也有所改善。 In order to improve mechanical strength and burning-off property of molded combustible cartridge cases, a new adhesive CK and a waterborne cross-linking agent DZ were added in to develop new formulation of the molded com- bustible cartridge cases. Optimum mass ratio of CK and DZ, mechanical strength and combustion performance were investi- gated. Results show that the optimum mass fraction of adhesive and cross-linking are 12.0% and 1.5% , respectively. Mechanical strength and elongation can reach to 36.7 MPa and 7.0% , which increase by 46.2% and 42.9% when compared to traditional samples. After combustion, the average residues before and after drying are decreased by 55.07% and 64.07%, respectively. Furthennore, there is no visible residue in the gun chamber after shooting on the gun test. These results indicate that the addition of the new adhesive CK and the waterborne cross-linking agent DZ significantly improve the mechanical strength, tenacity and burning-off properly of molded combustible cartridge cases.
