摘要/Abstract

摘要： 为提高引信及其包装箱的隔热或防火性能，避免在遇热或火焰时导致安全隐患，研究开发兼备防火及隔热性能的复合防护涂料。结合慢速与快速烤燃模拟试验，分析涂层结构设计对引信外壳及包装材料热防护行为和火安全行为的影响。结果表明：在慢速烤燃测试中，对钢板单独使用防火涂料时，不能起到隔热作用；在防火涂料上涂覆隔热涂料形成复合涂层后，防护效果有显著提升；在慢速和快速烤燃测试中，钢板背面温度分别降低了32 ℃和157 ℃. 进一步将复合涂层应用于引信壳体和引信包装箱板材，背面温度在慢速烤燃测试中分别降低33 ℃和21 ℃，在快速烤燃测试中分别降低105 ℃和117 ℃，起到了有效隔热或防火作用。

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.
