Abstract

The present invention relates to the technical field of conductive ink, in particular to a conductive ink with temperature-limiting characteristics, a preparation method and a heating tile, which are prepared from the following raw materials in mass percentage: 12% to 40% of carbon-based conductive filling material, 5% of conductive auxiliary material % to 8%, temperature-limiting material 7% to 13%, resin bonding material 10% to 28%, additive 9.5% to 14%, solvent 28% to 50%; the conductive auxiliary material is nickel-chromium alloy powder, and the The temperature-limiting material is titanium diboride heat-sensitive conductive material, and the Curie temperature of the titanium diboride heat-sensitive conductive material is 70-90°C. By adding titanium boride heat-sensitive conductive material and nickel-chromium alloy powder, the conductive ink has a self-limiting temperature function, and the self-limiting temperature effect is stable, preventing circuit damage and heat attenuation caused by circuit overheating. Moreover, when used as a heating tile, the conductive ink also has the characteristics of high cycle life and fatigue resistance. The PTC effect of the conductive ink can withstand multiple overheating shocks without failure.

Description

technical field [0001] The invention relates to the technical field of conductive ink, in particular to a conductive ink with temperature-limiting characteristics, a preparation method and a heating tile. Background technique [0002] Heating film is one of the commonly used heating materials for heating ceramics. The heating film contains a layer of graphene film resistors, which are printed on PET films with graphene resistor paste. When external substances such as water vapor infiltrate into the heating film during the use of the heating ceramics, the water vapor will cause some metal components to rust, and the rusted components may be damaged. When some debris falls and covers the heating film, the heating film will Local high temperature will be generated in this area. Generally, the accumulated heat temperature of thin film resistors cannot exceed the softening point temperature of the substrate (below 130°C), otherwise overheating will cause the heating film (PET fil...
