一种爆炸硬化用高聚物粘结塑性炸药及应用研究

针对目前爆炸硬化所用炸药的性能不足,研制成功一种高聚物粘结塑性炸药。该炸药以RDX为主炸药,烯烃类高聚物作粘结剂,并添加惰性粉体作爆速调节剂、癸二酸二辛酯增塑剂和液体石蜡钝感剂进行配方设计,运用该配方所配制的塑性炸药对高锰钢辙叉的爆炸硬化表明:在辙叉铸造基体硬度为HB170～190时,一次硬化后,表面硬度达到HB260～280;两次硬化后,表面硬度达到HB310～330。结果表明:该塑性炸药的爆炸硬化工艺性能稳定。

Application study on a polymer bonded plastic explosive after explosion hardening

A new polymer bonded plastic explosive was developed to meet the needs of explosion hardening.The polymer bonded plastic explosive based on RDX was made up of insensitive additives,plastic additives and the additives adjusting detonation velocity.The explosion hardening experiments on Hadfield steel of rail frogs show that the hardness on the surface of rail frogs can reach from HB170-190 to HB260-280 after explosion hardening one time and to HB310-330 after explosion hardening two times.The results show that performance and hardening process of the explosive are stable and reliable.
