Title:
ULTRA THICK BAMBOO-WOOD COMPOSITE PANEL, ULTRA THICK SOLID WOOD COMPOSITE PANEL AND MANUFACTURING METHODS THEREOF
Document Type and Number:
WIPO Patent Application WO/2010/072139
Kind Code:
A1
Abstract:
An ultra thick bamboo-wood composite panel and an ultra thick solid wood composite panel include a core, a face veneer and a back veneer. The core is an ultra thick rotary-cut veneer which has a thickness of 6mm -12mm. The face veneer and the back veneer are made of bamboo or wood. The core comprises a plurality of ultra thick veneers, the contiguous layers of the ultra thick veneer are assembled along the grain, a glue layer is arranged between contiguous veneers, the bonding agent of the glue layer is an aqueous macromolecule isocyanate adhesive. The ultra thick veneer of the core is a veneer through combing treatment of stress, and spot-shape or segment-shape cracks are formed in the direction along the grain of the loosened surface of every veneer. A manufacturing method of composite panel includes the following steps: making veneer, drying process, coating adhesive, assembling and hot pressing. The spot-shape or segment-shape cracks are formed in the direction along the grain of the veneer, the processed veneer is used for core. Compared with the prior composite panel of the same thickness, the composite panel has greatly reduced glue spread, no deformation and no distortion.
