Patent ID: 8795451

Claim:
A propellant for guns, the propellant comprising: at least one energy carrier; cellulose acetate butyrate having a melting point of over 200° C. and a glass transition temperature of over 130° C., said cellulose acetate butyrate having a concentration of from 2% by weight to 14% by weight in the propellant; and nitrocellulose, at least part of said nitrocellulose being alcohol-soluble nitrocellulose, said nitrocellulose being present in a concentration of at least 15% by weight in the propellant to serve as a binder, and at least 80% by weight of said nitrocellulose being alcohol-soluble nitrocellulose; and at least one plasticizer formed of the following components: from 30% by weight to 50% by weight of 2,4-dinitro-2,4-diazapentane, from 35% by weight to 55% by weight of 2,4-dinitro-2,4-diazahexane, and from 0% by weight to 30% by weight of 2,4-dinitro-2,4-diazaheptane; said cellulose acetate butyrate and said nitrocellulose in combination reducing brittle fracture of the propellant.
