▎ 摘　　要

NOVELTY - Multi-layer expansion-type conformal flame resistant and heat-insulating structure comprises a functional heat insulating layer (1), a functional flame resistant surface layer (2) and a functional expansion coating layer (3) from inside to outside sequentially covered outside the protected object. USE - Multi-layer expansion-type conformal flame resistant and heat-insulating structure used for passive flame-resistant device used in industrial equipment and safety protection system. ADVANTAGE - The structure is covered outside the protected object, and prevents heat transfer function, and has high radiating performance of the graphene, and can conduct heat rapidly at high temperature. DESCRIPTION OF DRAWING(S) - The drawing shows a multi-layer expansion-type conformal flame resistant and heat-insulating structure. 1Functional heat insulating layer 2Functional flame-resistant surface layer 3Functional expansion coating layer 4Valve 5Dismounting
