Abstract

The invention provides a heating film and a preparation method thereof, the heating film comprises a graphene composite fiber film, an inner current collecting part and an outer current collecting part, the inner current collecting part is located at two ends of the graphene composite fiber film, and the outer current collecting part is located on the outer surface of the inner current collectingpart; and the graphene composite fiber membrane comprises fibers and graphene dispersed in the fibers. The heating film disclosed by the invention is simple and reasonable in structural design and simple in preparation process, the obtained heating film can more uniformly dissipate heat, and the energy loss and waste are reduced. The maximum unit power density of the heating film can reach 1500w / m<2>, and the heating film can be used for a long time within the range of 180-260 DEG C and has a good application prospect.

Description

technical field [0001] The disclosure relates to the field of heating equipment, in particular to a heating film and a preparation method thereof. Background technique [0002] Energy issues have always been concerned, and industrial heating equipment generally has a high heating temperature and consumes a large amount of electricity. This is because the heating equipment usually heats a relatively closed system, while the traditional heating device is mainly an external package. The heating method of the resistance wire of ceramic material is from the middle to the surroundings, resulting in a certain difference in temperature distribution. In a closed space, the temperature is usually adjusted based on the lowest temperature point, which causes a certain degree of energy waste. [0003] Another kind of drying equipment mainly puts the objects to be dried on the conveyor belt, and uses electric heating tubes under or above the conveyor belt for heating. In this relatively o...
