| 摘 要： | 研究了多羟基醇类(LBA-22、LBA-201)、海因/三嗪类(CBA)、中性聚合物类(NPBA)和取代酰胺类(LTAIC)键合剂与RDX的表界面作用,并在RDX-CMDB推进剂中考察了这些键合剂的作用效果.采用接触角法和Wilhelmy吊板法测定键合剂与RDX的表界面特性参数,利用调和平均方程计算粘附功.结果表明CBA与RDX间的接触角为35.2°,粘附功为135.01 mN/m.红外光谱中RDX(-NO2)基团的吸收峰红移22 cm-1至1510 cm-1,且吸收带展宽.RDX经键合剂表面改性后,推进剂高温最大抗张强度从空白样的1.02 MPa提高到2.01 MPa,低温延伸率提高140%.各键合剂与RDX间的表界面性能数据与推进剂力学性能改善情况基本一致. |

| Abstract: | The interfacial bonding between a series of bonding agents(including polyhydroxy alcohols bonding agents(LBA-22,LBA-201),hyantoin/triazines composite bonding agents(CBA),neutral polymeric bonding agents(NPBA) and substituted amides(LTAIC)) and RDX were studied.Meanwhile,all of the bonding agents were used to prepare RDX-CMDB propellants.The surface and interface parameters were measured by the contact angle method and Wilhelmy plat method,and adhesive work was calculated based on the harmonic-mean equation.... |
| Keywords: | military chemistry and pyrotechnics surface and interface bonding agent RDX CMDB propellant |
