In situ cured booster explosive

摘要

The present invention relates to a method for preparing an in situ cured booster explosive by mixing explosive crystals with a prepolymer solution comprising a carboxyl (or hydroxyl)-terminated hydrophobic polyester and epoxidized linseed oil with chromium octanoate as a catalyst. The explosive mixture is pressed into desired size and cured at 60 DEG C. to 70 DEG C. for about 96 hours. The resulting in situ cured explosive has desirable safety and physical properties.
