摘要
合成了新型含异氰脲酸酯基的环氧树脂(ISEP)及柔性固化剂(TPA)。以ISEP和TPA为粘结剂和固化剂组分,以联二脲为填料,制得了环氧树脂胶片。在室温、高温(50℃)、低温(-40℃)下胶片的拉伸强度和延伸率分别为6.44MPa,124.15%;2.68MPa,85.24%;27.38MPa,24.09%。对推进剂进行了包覆,发现包覆层与推进剂粘接良好。对装药进行了静止发动机试验,获得了平稳的压力-时间曲线。包覆层材料的红外、可见光和激光透过率分别为90.4%、85.4%和84.2%。TGA曲线表明材料的热稳定性好。
A novel epoxy resin containing isocyanurate group (ISEP) and a novel flexible curing agent (TPA) are synthesized. The mechanical properties of the composite by using biurea as filler are studied. Its tensile strength and elongation are 6.44 MPa and 124.15% at 20℃, 2.68 MPa and 85.24% at 50℃, 7.38 MPa and 24.09% at -40℃, respectively. A propellant is inhibited by this composite. The threeway smoke signature results of the inhibitor show that the transmit ratio of visible light and laser exceeds 80 percent, while 90.4% for IR. The thermal stability of the inhibitor is also studied by TGA.
