본 발명은 단열재 폼에 관한 것으로, 보다 상세하게는 고폭화약이 충전되는 탄두 및 유도무기 등의 내면에 적용되어 온도 변화 및 충격 등의 외부 환경으로부터 상기 탄두 및 유도무기 등의 저장성과 생존성을 극대화시키는 고폭화약용 단열재 폼에 관한 것이다. 본 발명의 고폭화약용 단열재 폼은 다공성 입자; 하이드록시기를 포함하는 프리 폴리머; 및 이소시아네이트;를 포함하여 제조되고, 상기 프리 폴리머는 폴리부타디엔계, 폴리에스테르계, 폴리에테르계, 폴리실록산계 또는 플루오르계 중 어느 하나가 적용된 것을 특징으로 한다.
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.
