Method for producing hard wood composite floor

The invention discloses a method for producing wood composite floor which includes the following steps: prepressing the base material for not less than 20 seconds at pressure above 8MPa and temperature above 100 degree Centigrade; cooling the base material, sanding the base material according to the required thickness with grinding belt whose mesh is above 100m, then choosing one side of the base material as decorative surface, and sanding the decorative surface with grinding belt whose mesh is above 200m to obtain a base material with a thickness tolerance of í‚0.3mm and an angularity of less than 2%; combining the base material, the faced layer, the balance layer into a blank, heat pressing for not less than 20 seconds at the temperature above 150 degree Centigrade and pressure above 5Mpa; then cooling the treated base material for 8 hours or longer, cutting and machining into the finished product in the mortising machine.
