Abstract
A radiation-free heating pad and a processing technology thereof is provided. The radiation-free heating pad includes heating wires, a fiber layer, a flexible shielding layer, and a reinforcement layer. The heating wires are uniformly arranged on the fiber layer in a serpentine pattern, a layer of aluminum foil is arranged on each of an upper side and a lower side of the fiber layer, and the aluminum foil tightly wraps the heating wire. The flexible shielding layer is arranged outside the aluminum foil, and the reinforcement layer is arranged outside the flexible shielding layer. The radiation-free heating pad is based on the Faraday cage effect, and an electromagnetic field generated when an electric current passes through the heating wire can be effectively counteracted by a double shielding structure composed of the aluminum foil and the flexible shielding layer.
