Inorganic thermal-insulation fireproof hydrophobic coating and preparation method thereof

The invention discloses an inorganic thermal-insulation fireproof hydrophobic coating and a preparation method thereof. The coating comprises the following components: an inorganic silicon solution, graphene, white quartz sand, ground calcium carbonate, polypropylene fibers, titanium dioxide, mica powder, sodium hexametaphosphate, a phase change master batch, ceramic microspheres, nano silicon dioxide, calcium formate, aluminum powder, a preservative, a leveling agent, an antifoaming agent, a hydrophobic agent, AMP-95 regulator and deionized water. According to the invention, inorganic mattersare basically adopted, and the phase change master batch taking vermiculite powder as a raw material is matched with calcium formate, aluminum powder, cement and other components, so that the heat-preservation, heat-insulation, fireproof and hydrophobic functions can be well achieved, no VOC is contained, and the harm to the environment can be reduced. The method has potential market value. 本发明公开了一种无机保温隔热防火疏水涂料及其制备方法，涂料包
