Definitions
- the present invention relates to a highly reactive isocyanate component containing an organic isocyanate having at least two isocyanate groups, an organic metal compound-based catalyst and a compound containing an aromatic sulfonylisocyanate group. Furthermore, the present invention relates to a process for producing lignocellulose-containing materials using the highly reactive isocyanate component, such lignocellulose-containing materials and a sealant containing the highly reactive isocyanate component.
- lignocellulose-containing substances wood parts, such as wood layers, wood strips, wood chips, or wood fibers, wherein the wood fibers may possibly also originate from wood fiber-containing plants, such as flax, hemp, sunflowers, Jerusalem artichoke or rapeseed. Starting materials for such wood parts or wood particles are usually thinning wood, industrial wood and used wood as well as wood fiber-containing plants.
- the preparation of the desired lignocellulose-containing materials, such as wood particles by known methods, see, for example, M. Dunky, P. Niemt, wood materials and glues, pp. 91-156, Springer Verlag Heidelberg, 2002.
- Lignocellulose-containing moldings in the case of wood as lignocellulose here also called wood materials, are a cost-effective and resource-saving alternative to solid wood and have great importance, especially in furniture and as building materials obtained.
- wood materials are usually used wood layers of different thickness, wood strips, wood chips or wood fibers from different woods.
- wood parts or wood particles are usually pressed at elevated temperature with natural and / or synthetic binders and optionally with the addition of further additives to plate or strand-shaped wood materials.
