FLEXIBLE RESISTIVE HEATING ELEMENT

The technical solution relates to the field of electrical heating, in particular to flexible heating elements. The flexible resistive heating element comprises a heat-resistant fabric base and a conductive resistive layer formed by resistive carbon composite material applied to the basis of heat-resistant fabric in the form of a colloidal suspension. The resistive carbon composite material comprises carbon black with highly developed specific surface area of at least 300÷600 m 2 /g, particle size of 10 to 50 nm in combination with colloidal graphite preparations with a graphite particle size less than 4 microns and the heat-resistant polymer binder solution. Polyethylene terephthalate or lavsan is used as a heat-resistant fabric base. The resistive carbon composite material comprises carbon black OMCARB„¢ CH210, and/or CH220, and/or CH230 and OMCARB„¢ CH600, along with colloidal graphite preparations or C-0 or C-l, or natural graphitesmilled to particle size of less than 4 microns. A heat-resistant polyester based on terephthalic acid or adipic acid or sebacic acid, or ethylene glycol or diethylene glycol, or parts of the components mentioned, such as TF-60 resin is used as binder. Chloroform or methylene chloride, or dichloroethane, or other substances that can effectively dissolve polymeric binders are used as solvents. The use of the technical solution will allow enhancing the performance of the flexible resistive heating element: reliability, efficiency, adaptability to manufacturing of both the resistive element and the flexible electric heaters made of it.
