Multi-layer solid wood and preparation method thereof

The invention discloses multi-layer solid wood which is provided with a solid wood veneer and a middle-high density board/shaving board. A piece of melamine paper is arranged between the solid wood veneer and the middle-high density board/shaving board. The solid wood veneer, the melamine paper and the middle-high density board/shaving board are heated, pressurized and composited to form an integrated finished product structure through a hot press. The preparation method of the multi-layer solid wood comprises the steps that firstly, the multi-layer solid wood, the middle-high density board/shaving board, the melamine paper and the hot press are prepared; then, the melamine paper is placed between the solid wood veneer and the middle-high density board/shaving board; finally, heating and pressurizing are performed through the hot press to composting the multi-layer solid wood, the middle-high density board/shaving board and the melamine paper into the integrated finished product structure. The preparation pro
