EXPLOSIVE CONTAINING URETHANE BINDER

摘要

The present invention related to casting compound gunpowder which improved heat or mechanical property and stability, and had proper operation delay time recharged with gunpowder particle and filler and so forth on urethane bond agent and method of manufacturing.The present invention comprises a process of mixing liquid phase prepolymer, plasticizer, antioxidant; a process of mixing recharging like gunpowder particle(R.D.X), aluminium particle, ammonium perchlorate particle; a process of adding low molecular weight body aliphatic diol; a process of mixing isocyanate conforming to 80-100% of stoichiometric quantity need to polymer reaction with hydroxylic; a process of achieving polymer reaction of hydroxylic with isocyanate by heat hardening after recharging gunpowder slurry to coal body or mold.
