The invention provides a heat-radiation membrane material and belongs to the technical field of heat-radiation material. The heat-radiation membrane material is capable of solving a problem that the prior membrane material is comparatively single in heat radiation method, and poor in heat-radiation effect under a condition that heat is high or a fire source exists. The heat-radiation membrane material at least includes a first heat radiation fin and a heat absorption reaction module. One face of the first heat radiation fin contacts a heating object and the other face of the first heat radiation fin is connected with the heat absorption reaction module. The heat absorption reaction module is used for absorbing heat generated by the heating object. The heat-radiation membrane material can be used for improving the heat radiation effect of a heat-radiation membrane material.
