Problems solved by technology
[0003] However, most of the previous technologies were limited to technologies such as heat-resistant structures and heat-insulating materials, and the manufacturing method of using carbon fiber filaments to manufacture heating elements was complicated, the degree of automation was very low, and the production cost was high by using consumable auxiliary materials such as spindles. The presence of fluff in carbon fiber filaments leads to problems such as uneven surface of the heating element

Abstract
The invention relates to a method for preparing a carbon-carbon composition heating wire by taking a carbon fiber yarn as base. The method comprises the steps of: (1) arranging adhesive layer(s) on the single side or the two opposite sides of the carbon fiber yarn, and arranging organic synthetic membrane layer(s) on the adhesive layer(s) to obtain carbon fiber yarn intermediate, wherein the melting points of the organic synthetic membrane layer(s) and the adhesive layer(s) are below 350 DEG C; (2) bonding the carbon fiber yarn intermediate onto a heat-resistant spindle by the adhesive layer(s); (3) carrying out heat treatment in an oxidizing furnace; (4) carrying out heat treatment in a non-oxidizing furnace; and (5) finally, separating the carbon fiber yarn intermediate from the heat-resistant spindle to obtain the carbon-carbon composition heating wire. The invention also relates to related carbon-carbon composition heating wires. The method for preparing the carbon-carbon composition heating wire by taking the carbon fiber yarn as base is ingenious in design as well as simple and reasonable in technology, and realizes simplification and automation of the technology so as to realize large-scale production; and the material of the spindle can be recycled, so that the production cost is reduced, and the surface quality of a heating body is improved; and therefore, the method is suitable for large-scale popularization and application.
