Delayed quick cure rocket motor liner |
摘要 |
An improvement to the process of applying a rocket motor liner to an inside surface of a rocket motor casing by coating the casing with a rocket motor liner composition and then curing the liner composition. Typical rocket motor liner compositions include the product of a hydroxyl-terminated polybutadiene prepolymer; a diisocyanate curing agent for forming urethane linkages with said prepolymer; a trifunctional aziridine bond promoter; a filler; and a curing catalyst comprising maleic anhydride, magnesium oxide, and triphenyl bismuth. This invention may use an alkaline carbon black filler and/or a curing catalyst which does not include magnesium oxide.
