摘要:
为了减小炸药装药膨胀力对弹体后端盖的力学危害,采用端羟基聚丁二烯(HTPB)为黏结剂、2,4-甲苯二异氰酸酯(TDI)为固化剂、二月桂酸二丁基锡(T-12)为催化剂,成功制备了一种多孔性缓冲材料;采用力学实验机、SEM等测试方法研究了固化温度对HTPB发泡特性和缓冲材料内部结构、压缩率的影响。结果表明,固化温度对HTPB发泡体积影响显著,在30~70℃范围内,随着固化温度的增加,发泡体积从0.12cm3增至0.56 cm3;90℃固化时发泡体积从0.56 cm3减小至0.45 cm3。压缩率在70℃时达到最大值,为65%。根据不同固化温度下缓冲材料的内部结构和压缩率,确定气孔直径均匀,压缩率最大时的温度(70℃)作为缓冲材料的固化温度。
Abstract:
To reduce the mechanical damage of the explosive charge expansion force to the end cover of the projectile body, a porous buffer material was successfully prepared by using HTPB as binder, TDI as curing agent and T-12 as catalyst. The effect of curing temperature on the foaming characteristics of HTPB and the internal structure and compression ratio of buffer material was studied by mechanical testing machine and SEM. The results show that the curing temperature has a great influence on the foaming volume of HTPB. In the range of 30 to 70℃,the foaming volume increases from 0.12cm3 to 0.56 cm3 with the increase of curing temperature, and the foaming volume decreases from 0.56cm3 to 0.45 cm3 when curing at 90℃. The compression ratio reaches a maximum of 65% at 70℃. According to the internal structure and compression ratio of buffer material at different temperatures, the curing temperature is determined to be 70℃ with uniform pore diameter and maximum compression ratio.
