FLEXIBLE RESISTIVE HEATING ELEMENT

摘要

The invention relates to the field of electric heating, and more particularly to flexible heating elements. A flexible resistive heating element comprises a heat-resistant fabric base and a current-conducting resistive layer that is based on a resistive carbon composite material applied in the form of a colloidal suspension to the heat-resistant fabric base. The resistive carbon composite material contains carbon black with a highly developed specific surface area of not less than 300-600 m2/g and a particle size of from 10 to 50 nm in combination with colloidal graphite preparations with a graphite particle size of less than 4μm, and a heat-resistant polymer binder solution. Polyethylene terephthalate or lavsan is used as the heat-resistant fabric base. The invention makes it possible to improve the performance characteristics of a flexible resistive heating element, namely the reliability, efficiency and manufacturability both of the resistive element itself and of flexible electric heaters based thereon.
