The application provides a battery thermal runaway coating based on a metal organic framework material and belongs to the technical field of new energy battery thermal management and safety protection. The application uses a high-temperature-resistant diaphragm as a base material, coats a mixture of A components (amine-functionalized ZIF-8, surface magnetic modification hexagonal boron nitride nanosheet, soluble polyimide, light-cured monomer and photoinitiator) and B components (natural camphor microparticles and AIBN) and uses a magnetic field to drive two-dimensional boron nitride to be arranged in a forced orientation, uses ultraviolet light to pre-cure and lock the orientation, makes camphor sublimate to form micron-level through holes through step-by-step heating, uses primary amines on the ZIF-8 to irreversibly capture hydrogen fluoride gas, uses the hexagonal boron nitride nanosheet to eliminate local hot spots, uses camphor sublimation to provide a rapid diffusion channel, uses light-cured crosslinked monomers to enhance the toughness of a gel network and prevent high-temperature cracking, so that a long-acting thermal runaway safety protection coating is obtained and the application is used in the fields of aviation power batteries and closed space power supply systems.
