Abstract

Solid gas generating and gun propellant compositions which employ certain nitroaminotetrazole salts such as guanidinium 5nitroaminotetrazole, ammonium 5-nitroaminotetrazole and hydrazinium 5-nitroaminotetrazole as modifying ingredients in admixture with an oxidant and a suitable compatible binder material.

Claims

1. A SOLID PROPELLANT COMPOSITION COMPRISING AN OXIDANT, A NITROAMINOTETRAZOLE SALT SELECTED FROM THE GROUP CONSISTING OF GUANIDINIUM 5-NITROAMINOTETRAZOLE, AMMONIUM 5NITROAMININOTETRAZOLE AND HYDRAZINIUM 5-NITROAMINOTETRAZOLE AND A COMPATIBLE BINDER.

2. The solid propellant composition of claim 1 wherein said oxidant is present in amount within the range of from about 5 to about 90 percent by weight, said nitroaminotetrazole salt is present in an amount within the range of from about 5 to about 70 percent by weight and said binder is present in the amount within the range of from about 5 to about 28 percent by weight of the total composition.

3. The solid propellant composition of claim 2 wherein said oxidant is selected from the group consisting of 1,3,5,7-tetranitro-1,3,5,7-tetraazacylcooctane, ammonium nitrate, 5-aminotetrazole nitrate, ammonium perchlorate and mixtures thereof.

4. The solid propellant composition of claim 3 wherein said compatible binder is a polymer selected from the group consisting of a polyester, a polyurethane, a polyglycol, a polybutadiene, a polybutadiene having carboxy functionality, a polybutadiene having hydroxy functionality, a polyester having hydroxy functionality, a polyether, a vinyltetrazole, a glycidyl ether epoxy resin and copolymers thereof.

5. The solid propellant composition of claim 4 wherein said oxidant is 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane and said compatible binder is selected from the group consisting of the terpolymer of 2-methyl-5-vinyltetrazole:

butyl acrylate;

acrylic acid, hydroxyl-terminated polybutadiene cured with an isocyanate and polyglycol adipate.

6. The solid propellant composition of claim 2 wherein said compatible binder is a polymer selected from the group consisting of a polyester, a polyurethane, a polyglycol, a polybutadiene having carboxy functionality, a polybutadiene having hydroxy functionality, a polyester having hydroxy functionality, a polyether, a vinlytetrazole, a glycidyl ether epoxy resin and copolymers thereof.
