Description

technical field [0001] The invention relates to the technical field of heating films, in particular to a heating film with a graphene-based hot-pressed copper sheet structure and a preparation method thereof. Background technique [0002] There are many ways and materials that can be used for heating, including electric heating, infrared heating and electromagnetic heating. Electric heating is widely used due to its high heating efficiency and ease of use. The materials used for electric heating are mainly electrical conductors, wherein electrical conductors include metal conductors and polymer conductors. Due to the simple preparation, low density and good flexibility, polymer-based conductive composite materials are widely used to make conductive heating materials. The development of society has higher and higher requirements for conductive heating materials. For example, the heating body is required to have good flexibility, can be deformed arbitrarily, can withstand hi...

AI Technical Summary

Problems solved by technology

The existing graphene heating film has poor aging resistance, is easy to wear, and cannot be used for a long time; in addition, the existing graphene heating film used in warm clothes is generally sprayed with a silver paste layer on its surface as a conductive layer. Good heating performance and has the function of sterilization

However, when the clothes are cleaned, the silver paste layer is easily cracked due to rubbing, and the resistance of the silver paste layer increases, which in turn affects the application of the heating device.
