Abstract:In view of the safe problem of navy solid campaign missile high energy propellant when there is sudden fire, discuss heat insulation material including synthetic resin coating and aerogel coating. Separately introduce the epoxy resin material, polyurethane material and aerogel material, summarize the research progress of slow speed and fast speed cook-off test, analyze digital simulation of cut-off test, and look forward to the future coatings that can be used for solid engine fire and heat insulation. This research has certain guiding significance for future scientific research and production in this field.
