A solid gas generating agent and a preparation method thereof, comprising a polyether binder: 12% ~ 23%, 1.2% ~ 3.6%, curing agent, oxidizing agent 50% ~ 80%, 0% ~ 5% plasticizer, cooling agent 0% ~ 30%, 0% ~ 5% combustion regulator, other types of additives from 0% to 2%. The polyether binder is one or a combination of more than one ethylene oxide tetrahydrofuran copolyether, propylene oxide tetrahydrofuran copolyether as curing agent, toluene diisocyanate, isophorone diisocyanate, polyfunctional to one or more of the combination of aliphatic diisocyanate in the plasticizer for one or more the combination of sebacic acid two, citric acid three octyl acetate, glycerol three ethyl carbonate in three. The invention relates to a solid gas generating agent with a strong negative pressure index, and the pressure exponent is 0~-0.30, which provides a power source for a light kinetic energy interceptor (KKV) attitude control and orbit control power system.
