Title:
PRODUCTION METHOD OF WOODY MATERIAL
Document Type and Number:
Japanese Patent JP2017030311
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a production method of a woody material where the productivity of the woody material can be improved by significantly shortening time required for high frequency pressing while ensuring necessary adhesive strength and fine carbon fibers, especially carbon nanotubes are not used or a used amount can be suppressed.SOLUTION: In a production method of a woody material, a production intermediate 1A containing an adhesive is sandwiched between a pair of electrodes 45, 46, a high frequency voltage is applied between the electrodes 45, 46 and the adhesive is heated and then the woody material in which constituents 11 are bonded by the adhesive is obtained. An adhesive blended with graphite powders is used as the adhesive.SELECTED DRAWING: Figure 5
