Multilayer reinforced solid wood composite floor

A multi-layer strengthened solid wood composite floor comprises a floor body, a wear-resisting layer arranged on the top layer of the floor body, a sealing layer arranged on the bottom layer of the floor body, a heat insulation layer arranged on the side, close to the sealing layer, of the wear-resisting layer, a first protection layer arranged on the side, close to the wear-resisting layer, of the sealing layer, and a solid wood base material arranged in the middle of the floor body. The composite solid wood floor has the beneficial effects that the practicability of the composite solid wood floor is effectively improved, the wear-resisting effect of the floor body is effectively improved by arranging the wear-resisting layer, the service life of the floor body is prolonged, the solid wood base material is effectively subjected to heat-insulating and flame-retardant protection by arranging the heat-insulating layer and the flame-retardant layer, and the service life of the composite solid wood floor is prolo
