The invention discloses an electric heating film which comprises a substrate, a first heat reflection layer, a second heat reflection layer, a first heating element, a second heating element, first heat conduction paste, second heat conduction paste, a first heat preservation flame-retardant layer, a second heat preservation flame-retardant layer and silica gel. The substrate, the first heat reflection layer, the first heating element, the first heat conduction paste and the first heat preservation flame-retardant layer are sequentially connected from inside to outside; the substrate, the second heat reflection layer, the second heating element, the second heat conduction paste and the second heat preservation flame-retardant layer are sequentially connected from inside to outside; the first heat reflection layer is provided with a first groove, and the first heating element is located in the first groove; the second heat reflection layer is provided with a second groove, and the second heating element is located in the second groove; the silica gel is located between the first heat preservation flame-retardant layer and the second heat preservation flame-retardant layer and wraps the peripheries of the substrate, the first heat reflection layer, the second heat reflection layer, the first heat conduction paste and the second heat conduction paste, and the two ends of the first heating element and the two ends of the second heating element penetrate out of the silica gel.
Description
technical field [0001] The invention relates to the field of heating materials, more specifically, to an electric heating film. Background technique [0002] The electric heating film is a heating element composed of an electrical insulating material and a heating material encapsulated in it. It is a new type of electric heating element in recent years. It is mainly used for indoor heating and environmental temperature maintenance. It converts electrical energy into heat energy during work, and The heat energy is mainly transmitted outward in the form of radiation, but the existing electric heating film has a slow heating rate and low heating efficiency, and there is still a lot of room for improvement. Contents of the invention [0003] The present invention aims to provide an electric heating film, aiming at solving the problems of the electric heating film in the prior art that the heating speed is slow and the heating efficiency is low. [0004] To achieve this purpos...
