This invention discloses a low-cost heating resistor paste for thermal printheads. The paste uses porous ruthenium dioxide microspheres and porous lead ruthenate microspheres as heating resistor materials, and molybdenum oxide and manganese oxide glass powder as insulating and binding materials. Submicron-sized porous microspheres form the framework structure of the heating resistor material, while micron-sized porous microspheres fill the gaps between the submicron-sized microspheres, improving the particle filling rate of the resistor body. Manganese oxide enhances the bonding force between the glass and the heating resistor material, while molybdenum oxide strengthens the resistance stability at high temperatures. Simultaneously, the addition of nano-sized yttrium trioxide further reduces the porosity of the resistor body and improves the particle filling rate. This invention's heating resistor paste abandons traditional single-particle-size materials, significantly improving resistance consistency through a special particle size combination and the addition of nano-sized yttrium trioxide. It also improves thermal conductivity, resistance adjustment performance, energy resistance characteristics, and printing efficiency. The preparation process is simple and easy to promote.
