Fireproof multilayer solid wood composite floor

The fireproof multilayer solid wood composite floor comprises a fireproof layer, a base material layer and a balance layer which are sequentially arranged from top to bottom, the fireproof layer comprises a wear-resistant layer, a facing layer, a UV flame-retardant coating layer, a putty layer and a primer layer which are sequentially arranged from top to bottom, and the primer layer is coated on the upper surface of the base material layer. The base material layer is a fireproof layer, the wear-resistant layer is a wear-resistant layer mainly composed of aluminum oxide, the facing layer is a layer of paper impregnated with melamine resin, and a ventilation channel is arranged in the base material layer. The fireproof layer is not only limited to the wear-resistant layer on the surface, and the facing layer and the UV flame-retardant coating below the fireproof layer can play a good fireproof role; the ventilation channels in the base material layer are used for reducing the heat conductivity, when the temper
