Particle Agglomeration Process for Wood and Cork Industrial Sectors

Abstract

This invention relates to a particle agglomeration process of wood and cork which uses an agglomerating system consisting of a pre-polymer of hydroxyl terminated polybutadiene (HTPB), a di-isocyanate and possibly a catalyst in order to obtain agglomerations of cork and/or wood particles with new characteristics and with new particle compositions. These products are used in the particle agglomeration industry in the wood sector (wood particles boards), specifically in the panels and veneers sub-sector and in the cork agglomeration industry sub-sector. This process enables the industrial reprocessing of residues and sub-products of sectors of wood and cork and at the same plays its part towards solving environmental problems by creating a viable and profitable alternative to storage and/or burning and/or depositing in the ground, in particular for what is referred to as cork powder and ‘terras’ and some wood residues, in particular fibre and polishing dust.
