Glue, a formaldehyde (HCOH) based resin, is an indispensable constituent of wood-based boards. However, formaldehyde evaporates during the manufacturing process, during exposure (furniture), and also during waste disposal. Since it belongs to the group of carcinogenic compounds, restrictions on its emission from wood-based boards have been imposed all over the world. Among the methods developed for diminishing this toxic emission, there have been the synthesis of the glue which permits reducing the mol percent of HCOH, or binding HCOH in situ by ammonium salts. In this study we propose a solution of the problem, namely a new glue, based on poly-silicon polymers, which has an optimized viscosity and wets the wood well. The new ligno-cellulose/poly-silicon composite has the required mechanical properties and is absolutely harmless to the environment.
