The invention discloses an aluminum
alloy base plate-based
rare earth thick film circuit controllable
electric heating element and a preparation technology thereof. The
electric heating element comprises a substrate and a series electronic
sizing agent, wherein the series electronic
sizing agent is prepared on the substrate, the series electronic
sizing agent comprises a packaging sizing agent and a
rare earth electrode sizing agent, and a
rare earth medium sizing agent and the series electronic sizing agent respectively consist of a function phase, an inorganic bonding phase and an organic dissolvent carrier. The series electronic sizing agent is prepared on an aluminum
alloy base plate in the manner of a thick film circuit. The series electronic sizing agent further comprises a series rare earth electric resistance sizing agent. The invention further discloses the prescription of the aluminum
alloy base plate, the packaging sizing agent, the series rare earth electric resistance sizing agent, the rare earth
electrode sizing agent and the rare earth medium sizing agent. The invention has the advantages of being high-speed in
heat transfer and heat dissipation, even and controllable in
heating temperature field, good in compatibility, firm in combination, large in
power density, high in
heat resistance and
impact resistance, and the
electric heating element has high-temperature
far infrared function, are green, environment-friendly, energy-saving, low-carbon, safe and reliable.
