This creation involves a coating structure with flame-resistant and aldehyde-removing properties, including topcoat, flame-resistant coating and substrate, the base material is a surface, and the middle is a fire-resistant coating composed of silicate aqueous solution, igneous rock powder and dolomite powder applied on the substrate, the top coat can be a PU, UV or common water-based paint on the market with chitosan and nano-silicon chips added. After the flame-resistant coating is dry, it is applied on the flame-resistant coating. Among them, the coating used for flame-resistant coatings is based on silicate aqueous solution, using an appropriate amount of dolomite powder as a flame-resistant agent, igneous rock powder as an expansion agent, and mixing an appropriate amount of water. The coating will expand when exposed to flames, and then Achieve flame resistance and does not contain common volatile organic compounds (VOC) and formaldehyde. Chitosan is added to the topcoat as an aldehyde scavenger, and nan
