Carbon paste for electric heating film
1. The heating carbon paste and the far-infrared electric heating film based thereon, its raw material formula includes the following components by weight: 15-20 parts of carbon powder; 10-20 parts of graphite; 5-10 parts of calcium carbide powder; 35 parts of organic carrier ~70 parts; 1~5 parts of dispersant.
2. The organic carrier includes epoxy resin, polyurethane, acrylic resin and ethylene oxalate; the far-infrared electric heating film based on it includes a base film, a heat-generating carbon paste strip, at least two current-carrying strips, The polyester film on the current-carrying strips, the current-carrying strips are arranged parallel to each other and distributed at intervals, and the heat-generating carbon paste strips are coated with the above-mentioned heat-generating carbon paste.
