Embodiment 1

[0022] 1. First, pre-press the substrate:

[0023] The base material of this embodiment adopts 11.6mm five-layer whole meranti multi-layer plywood, and the base plate is sent into a hot press to be hot-pressed at a temperature of 175 degrees Celsius and a pressure of 25 MPa for 35 seconds. After pressing, the warpage of the plate 1220mm×2440mm is 4%, and the thickness tolerance is ±0.5mm.

[0024] 2. Second, perform sanding treatment:

[0025] Cool the pre-pressed plate for 15 minutes and then put it into the sander, and use the 180-mesh abrasive belt to sand the plate to determine the thickness, and the sanding amount is 0.30mm. Then select the side with better quality of the plate as the decorative surface, sand the surface of the plate twice with a 300-mesh abrasive belt, and the sanding amount is 0.10mm, so that the warpage of the plate is less than 1.5%, and the thickness tolerance is ±0.2mm within.

[0026] 3. Third, carry out the decorative layer finish:

Embodiment 2

[0037] 1. First, pre-press the substrate:

[0038] What the base material of present embodiment adopts is the composite board of the medium density fiberboard (MDF) of 6mm five-layer whole poplar wood multi-layer plate that is pressed and glued up and down respectively, and total thickness is 12mm. The temperature and the pressure of 20MPa are hot pressed, and the time is 45 seconds. After pressing, the warpage of the plate 1220mm×2440mm is 4%, and the thickness tolerance is ±0.6mm.

[0039] 2. Sanding treatment:

[0040] Cool the pre-pressed board for 15 minutes and send it to the sander. Select the side with better quality as the decorative surface, and sand the surface of the board twice with a 300-mesh abrasive belt, and the sanding amount is 0.40mm , so that the thickness tolerance of the plate is within ±0.2mm.

[0041] 3. Press and paste the protective layer of the facing:

[0042] The sanded panels were treated with figure 2 The structure shown, that is, 30 grams o...

Embodiment 3

[0048] 1. Substrate pre-pressing treatment:

[0049] The base material used is 11.6mm seven-layer poplar wood-mixed wood multi-layer plywood, and the base plate is sent into a hot press at a temperature of 130 degrees Celsius and a pressure of 15 MPa for 40 seconds. After the plate is cooled for 30 minutes, it is sent into the hot press again to press at a temperature of 185 degrees Celsius and a pressure of 24 MPa for 30 seconds.

[0050] 2. Sanding treatment:

[0051] Cool the pre-pressed plate for 15 minutes and send it to the sander, and sand the plate with a 200-mesh abrasive belt to determine the thickness of the plate, and the sanding amount is 0.40mm. Then select the side with better quality of the plate as the decorative surface, sand the surface of the plate twice with a 300-mesh abrasive belt, and the sanding amount is 0.10mm, so that the thickness tolerance of the plate is within ±0.2mm.

[0052] 3. Decorative layer finish:

[0053] The sanded panels were treate...

Abstract

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 +/-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.

Description

technical field [0001] The invention relates to a production method of a solid wood composite floor, in particular to a production method of a solid wood composite floor that adopts a resin-impregnated surface layer laminated on the surface. Background technique [0002] Solid wood composite flooring has a real and natural appearance, low production costs, full use of resources, and excellent performance. It has broad application and development prospects. Traditional solid wood composite flooring usually uses paint as the final decoration and protection of the surface. After the paint is painted and cured many times, a decorative protective layer is formed on the surface of the solid wood composite floor. During the processing, a large amount of harmful organic volatile compounds (VOC) are released, which is harmful to the environment. and operator health. The investment of this decoration method is also very large. The equipment price of an ordinary domestic paint line i...
