The present invention discloses a high-temperature anti-sticking agent, a preparation method, and an application thereof. The high-temperature anti-sticking agent comprises expanded graphite, wherein silicon dioxide is uniformly deposited in the expanded graphite, and the mass ratio of the expanded graphite to silicon dioxide is 10 to 30 parts:0.4 to 1.8 parts. The high-temperature anti-sticking agent exhibits excellent hydrophilicity under the current hot bending process used for automotive windshields, can be diluted completely with water, is easy to use, flame-retardant and safe to use, and is environmentally friendly with no VOC emissions. During the low-temperature period (below 500°C) of the hot bending process, the agent expands in volume, forming a barrier on the ink surface. The scaly structure forms a thin film covering the ink surface, which does not melt during the entire glass bending process, thereby effectively preventing adhesion between the A and B glass layers.
