Abstract: The present disclosure discloses a waterborne inorganic anti-doodling ceramic paint for indoor walls and preparation method thereof; the ceramic paint is a dual-coating paint having an under-coating paint and a surface-coating paint. The advantage effects of the present disclosure is that: the main film-forming materials are inorganic materials, the solvent is mostly deionized water, VOC emission is extremely low, thereby having a characteristics of safety, health and environmental protection; overcoming the shortcomings of multi-components of ceramic paint needs to be aged before use, while the under-coating paint and the surface-coating paint of the present disclosure are all single-component and can be directly used, easily to apply and fast; having an anti-doodling effect, when a marker doodling on the walls, it can be easily erased; the coating has a low surface tension which can isolate the outdoor moisture and prevent the walls from getting wet and mildewed.
