High-performance heat-proof coating based on interpenetrating network structure and preparation method of high-performance heat-proof coating

The invention discloses a high-performance heat-proof coating based on an interpenetrating network structure and a preparation method of the high-performance heat-proof coating. The heat-proof coating comprises silicon rubber, silicon resin, ceramic forming filler, a fluxing agent, heat insulation filler, shape-maintaining filler, a flame retardant, a diluent, a curing agent and a catalyst. The preparation process is simple, and room-temperature curing molding is realized. Compared with a traditional silicone rubber-based heat-proof coating, the coating provided by the invention has better mechanical properties under the condition that the thermophysical properties and the interface bonding properties are equivalent, a firm porcelain layer is generated in situ at high temperature and does not fall off, and the safe flight of an aircraft in a relatively harsh aerodynamic thermal environment is ensured. 本发明公开了一种基于互穿网络结构的高性能防热涂层及其制备方法，本发明防热涂层包括：硅橡胶、硅树脂、成瓷填料、助熔剂、隔热填料、维形填料、阻燃剂、稀释剂、固化剂、催化剂，本发明防热涂层采用硅橡胶和特种硅树脂为双基体，制备
