Title:
WOOD/PLASTIC COMPOSITE BOARD AND ITS PRODUCTION METHOD
Document Type and Number:
Japanese Patent JP2006240086
Kind Code:
A
Abstract:

To provide a composite board and its production method which can curtail a production time and stabilize quality.

The composite board 10 is produced through a process (a) for producing a mixed material 16 by dry-mixing a wood material 12 and a plastic material 14, a process (b) for molding a forming mat 18a by dry-forming the mixed material 16, a process (c) for molding a single layer board 18b by hot-pressing the forming mat 18a, a process (d) for laminating a lamination material 20b on the surface of the single layer board 18b, and a process (e) for integrating the single layer board 18b and the lamination material 20b by hot-pressing before the single layer board 18b is cooled. Even when the wall thickness is thick, a time necessary for the hot-pressing in the process (e) can be curtailed, the total production time can be curtailed, and the occurrence of burning in the surface of the composite board can be prevented.
