Abstract
A sandwich structural coating with both fire resistance and thermal insulation properties is developed to improve the heat insulation/fire resistance performances of fuze and its packaging box. The use of coatings help to avoid the potential safety hazards caused by thermal stimulation. The slow and fast cook-off tests were made to analyze the thermal insulation performances of different coating structures. The results show that the fireproof coating used alone could not serve as a thermal insulation in the slow cook-off test. After applying an insulation outer coating layer, a strong protective layer could be formed under thermal stimulation. The temperature on the back side of steel plate is reduced by 32℃ in the slow cook-off test and 157℃ in fast cook-off test. The sandwich structural coating is applied to fuze shells and their packaging boxes. And it plays an important role in heat insulation/fire resistance performance. Compared with the unprotected specimen, the sandwich structural coatings could reduce the temperatures on the back side of steel plate by 21℃ and 33℃ in the slow cook-off test, and 117℃ and 105℃ in the fast cook-off test.
