摘要:
Cross-linked double base propellants having improved low temperature mechanical properties are provided. The improved properties are achieved by using a mixture of polyglycoladipate and polycaprolactone as the binder prepolymer and employing a lacquer grade nitrocellulose containing 12.1% N to 12.6% N as the source of nitrocellulose.

1. In a double base plastisol type propellant containing nitrocellulose and liquid nitrate esters in combination with between 0.5 and 2.0 percent by weight of either 2,4-tolylene diisocyanate or hexamethylene diisocyanate based on the weight of said propellant, the improvement consisting in the incorporation of between 0.5 and 2.0 percent by weight of an aromatic hydroxy compound based on the weight of said diisocyanate, thereby rendering said propellant homogeneous and void-free, said aromatic hydroxy compound selected from the group consisting of 1,3-DIHYDROXY BENZENE, 1,2-DIHYDROXY BENZENE, 1-METHYL-3,5-DIHYDROXY BENZENE, 1,4-DIHYDROXY BENZENE, 1,2,3-TRIHYDROXY BENZENE, 1,3,5-TRIHYDROXY BENZENE, 1,3-DIHYDROXY-2-NITRO-BENZENE, 1-HYDROXY-3-ACETO-BENZENE, 1,3-DIHYDROXY-2-METHYL BENZENE, 1-METHANOL-2-HYDROXY BENZENE, AND 1,3-DIHYDROXY-2,4-NITROSO-BENZENE.
摘要:
A PROCESS FOR THE PREPARATION OF AN EXPLOSIVE COMPOSITION CONTAINING NITROCELLULOSE AND AN EXPLOSIVE NITRIC ESTER, SUCH AS NITROGLYCERINE. THE NITROCELLULOSE IS FIRST MIXED WITH A LIQUID DISPENSING AGENT, SUCH AS ETHYLENE GLYCOL AND/OR GLYCERINE, AND THEREAFTER MIXED WITH THE EXPLOSIVE NITRIC ESTER.

1. A GELATIN EXPLOSIVE INCLUDING, IN ITS FORMULA, HOLLOW RESINOUS NITROGEN FILLED PLASTIC PELLETS WHICH ARE NOTT ATTACKED BY OTHER INGREDIENTS OF THE EXPLOSIVE AND ARE OF A SIZE SUCH THAT THEY PASS A U.S.S. NO. 8 SCREEN, SAID PELLETS BEING INCLUDED IN AN AMOUNT BETWEEN ABOUT 1.1% AND ABOUT 3% BY WEIGHT.
