Title
(EN) PROCESS FOR THE PREPARATION OF LIGNIN BASED POLYURETHANE PRODUCTS
(FR) PROCÉDÉ DE PRÉPARATION DE PRODUITS DE POLYURÉTHANNE À BASE DE LIGNINE
Abstract
(EN) A process for the production of a lignin based polyurethane products is provided. The process comprises mixing at least one dried lignin and at least one isocyanate to form a lignin-isocyanate mixture, and submitting the lignin-isocyanate mixture to a polymerization reaction. The polymerization reaction may include heating the lignin-isocyanate mixture, adding at least one catalyst to the lignin-isocyanate mixture, or mixing the lignin-isocyanate mixture with a resin comprising at least one polyol, in the presence of at least one catalyst. The lignin based polyurethane products obtained by the process may be rigid foams, flexible foams, rigid boards, rigid blocks, coatings, packagings, adhesives, binders, sealants, elastomers, Thermoplastic Polyurethanes or Reaction Injection Moldings. There is also provided a mixture comprising at least one dried lignin and at least one isocyanate for use in the production of a lignin based polyurethane products.
(FR) L'invention concerne un procédé pour la production de produits de polyuréthanne à base de lignine. Le procédé comprend le mélange d'au moins une lignine séchée et d'au moins un isocyanate pour former un mélange lignine-isocyanate, et la soumission du mélange lignine-isocyanate à une réaction de polymérisation. La réaction de polymérisation peut comprendre le chauffage du mélange lignine-isocyanate, l'addition d'au moins un catalyseur au mélange lignine-isocyanate, ou le mélange du mélange lignine-isocyanate avec une résine comprenant au moins un polyol, en présence d'au moins un catalyseur. Les produits de polyuréthanne à base de lignine obtenus par le procédé peuvent être des mousses rigides, des mousses souples, des panneaux rigides, des blocs rigides, des revêtements, des emballages, des adhésifs, des liants, des produits d'obturation, des élastomères, des polyuréthannes thermoplastiques ou des produits moulés par moulage par réaction. L'invention concerne également un mélange comprenant au moins une lignine séchée et au moins un isocyanate destiné à être utilisé dans la production de produits de polyuréthanne à base de lignine.
