The invention discloses a multifunctional spontaneous temperature regulating film, which includes at least a functional material carrier layer and an insulation layer close to the skin from outside to inside; the functional material carrier layer is a sealed cavity structure composed of a water-tight flexible material, and the sealed cavity The body is loaded with at least cooling or heating chemical raw materials; the thermal insulation layer is composed of a material having waterproof and thermal insulation performance. The film can be prepared as a facial mask or eye mask for facial skin. If it is loaded with heating chemical materials, the thermal insulation layer allows the heat emitted from the carrier layer of the functional material to be transferred to the skin uniformly and stably, and the heat transferred to the skin will not be lost quickly, so as to avoid the low initial temperature and low temperature. The risk of scalding effectively keeps the skin at a stable and appropriate temperature; if it is loaded with refrigeration chemical materials, the thermal insulation layer makes the functional material carrier layer unable to absorb the heat of the skin instantly, avoiding local frostbite, and causing the functional material carrier layer and the skin Heat exchange occurs evenly, and the cooling time is significantly extended. |
