Abstract (en)
[origin: WO2021182980A1] The invention relates to a process for the production of new polyurethane materials from polyols and wood waste and / or wood-like waste. This method is characterized by the use of polyol synthesized from wood waste and / or wood-like waste polyols or petrochemical polyols are used. A polyol mixture is prepared by mixing 1-100 parts by mass of polyols obtained from wood waste and/or 1-100 parts by mass of polyols obtained from wood-like waste and/or 1-100 parts by mass of petrochemical oligomerols and 0.01-10 parts by mass catalysts. Moreover, surfactants, anti-foaming agents, blowing agents and milled waste after wood processing or milled wood-like waste can be used. The resulting polyol mixture is then mixed with the isocyanate in an NCO / OH molar ratio ranging from 0.5 to 4.
