Process for preparing inert solid propellant compositions and inert solid propellant compositions

摘要

The present invention provides, based on the total weight of the composition, 0.01% to 15% by weight of a binder comprising a hydroxyl terminated polymer; 0.01 wt% to 10 wt% of a curing agent including an isocyanate-based compound; 0.01 wt% to 10 wt% of a plasticizer including an ester-based compound; 0.01% to 10% by weight of an antioxidant; C ₁₆ H ₃₀ O ₄ Sn (CAS No. 301-10-0) 0.001 wt% to 5 wt% of a curing catalyst; and 70 wt% to 90 wt% of a solid raw material; during the manufacturing process of an inert solid propellant composition comprising, adjusting the hardness of the composition by adjusting the equivalent ratio (-NCO/-OH) of the hydroxyl group (-OH) of the binder and the isocyanate group (-NCO) of the curing agent within the range of 0.5 to 1.3; and The above C ₁₆ H ₃₀ O ₄ Sn (CAS No. 301-10-0) Controlling the viscosity of the composition by adjusting the content of the curing catalyst comprising a 0.001% by weight to 5% by weight to provide a method for preparing an inert solid propellant composition comprising; and an inert solid propellant composition.
