Abstract
Thermal insulation foam for high explosives is applied to the inner surface of warheads and guided weapons filled with high explosives, thus maximizing the storability and survivability of warheads and guided weapons despite changes in temperature and external environmental factors such as impacts. The thermal insulation foam includes porous microspheres, a prepolymer having a hydroxyl group, and an isocyanate, wherein the prepolymer includes any one selected from among a polybutadiene-, a polyester-, a polyether-, a polysiloxane-, and a fluorine-based prepolymer.
