METHOD FOR DECREASING VOLATILITY OF CARBOXYLATE RUBBER-BASE SOLID-PROPELLANT COMPOSITIONS OF LIQUID FERROCENE COMPOUNDS AND HIGH-MODULUS CARBOXYLATE RUBBER-BASE SOLID-PROPELLANT COMPOSITION AND LIQUID FERROCENE-CONTAINING CATALYTICALLY ACTIVE PLASTICIZER Russian patent published in 2006 - IPC C08J3/21 C08L13/00 C10L5/14 C06B29/22 

FIELD: fuel materials.

SUBSTANCE: invention relates to using ferrocene-containing catalytically active plasticizers in high-modulus solid-propellant composition for different designations possessing the enhanced exploitation stability and broadly regulated range of the combustion rate. The composition comprises the following components: 60-80 wt.-% of oxidizing agent, for example, ammonium and potassium nitrate or FPCh; 2-20% of aluminum; 5-15% of liquid carboxylate rubber; 1.5-3.5% of epoxy resin, for example, epoxydiane resin ED-20 or resin EC-N; 0.01-4% of liquid ferrocene compound; 0.5-3.5% of co-plasticizer, transformer oil and/or DBS; 0.05-0.5% of hardening accelerating agents, and 0.01-0.2% of surface-active substances. Method for preparing high-modulus solid-propellant composition of reduced volatility of liquid ferrocene compound involves preliminary dissolving the ferrocene compound in co-plasticizer in the mass ratio = (20-80):(1-99) followed by plasticizing a polymeric binding agent and its mixing with surface-active substance, aluminum, oxidizing agent and hardening accelerating agents. Invention provides enhancing the strength properties of the composition.

EFFECT: improved properties of compositions.
