Method for quick hot-press forming of laminated wood
The present invention discloses a method for quick hot-press forming of laminated wood. The method includes: drying a machined small wood material to a moisture content of 5-8 wt %; gluing the dried small wood material, and assembling and laying the dried small wood material to be a square material or a sheet material, where an adhesive for the gluing is a water-soluble adhesive having a solid content of 45-60 wt %; clamping the square material or the sheet material through a three-dimensional metal clamp; sending the clamped square material or sheet material together with the clamp into a microwave heating machine for microwave heating to obtain a formed laminated wood, where the time from the gluing to the entry into the microwave heating machine is controlled to not exceed 15 min. According to the present invention, a glued part that needs to be heated can be heated quickly, precisely and effectively, the gluing strength and production efficiency of the laminated wood can be significantly improved, and the cost of production energy consumption is reduced.
