- The invention relates to the field of electric enrgineering, and more particularly to a composite resistive carbon material, and can be used in the preparation of highly electrically conductive pastes and glues which provide reliable electrical contact, and also in the manufacture of industrial and domestic heaters. A resistive carbon composite material comprises current conducting phases based on highly electrically conductive grades of carbon black in the combination with highly electrically conductive colloidal grades of grafite, and a heat-resistant polymer binder. The carbon black, which provides high electrical conductivity, has a specific surface area of not less than 300-600m2/g and a particle size of from 10 to 50 nm; the colloidal graphite preparations have a graphite particle size of less than 5 mkm. The technical result of the claimed invention is increased specific conductivity and reduced resistance as a result of a the optimisation of the content of binder and of the selection of efficient conductive components.
The invention relates to the field of the 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 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 10-50 nm in combination with colloidal praphite preparations with a graphite particle size of less than 4 mkm, and a heat-resistant polymer binder solution. Polyethelene terephthalate or lavsan is used as the heat-resistant fabric base. The invention makes it possible to improve the performance charactceristics of a flexible resistive heating element, namely the reliability, efficiancy and manufacturability both of the resistive element itself of flexible electric heaters based thereon.
