Abstract: La presente invención se refiere a un proceso para preparar una resina adhesiva, donde la lignina es proporcionada en la forma de una solución acuosa y se mezcla con uno o más de glicerol diglicidil éter, poliglicerol diglicidil éter, poliglicerol poliglicidil éter, glicerol triglicidil éter, sorbitol poliglicidil éter, glicerol alcoxilado poliglicidil éter, trimetilolpropano triglicidil éter, trimetilolpropano diglicidil éter, polioxipropilen glicol diglicidil éter, polioxipropilen glicol triglicidil éter, diglicidil éter de ciclohexano dimetanol, resorcinol diglicidil éter, isosorbide diglicidil éter, pentaeritritol tetraglicidil éter, etilen glicol diglicidil éter, polietien glicol diglicidil éter que tiene de 2 a 9 unidades de etilen glicol, propilen glicol diglicidil éter que tiene de 1 a 5 unidades de propilen glicol, y/o diglicidil éter de diol terminal que tiene una cadena lineal de carbono de 3 a 6 átomos de carbono; y opcionalmente uno o más aditivos. La resina adhesiva es útil por Ejemplo en la fabricación de laminados, aislantes de lana mineral y productos de madera como la madera contrachapada, los tableros de fibra orientada (OSB), la madera de chapa laminada (LVL), los tableros de fibra de densidad media (MDF), los tableros de fibra de alta densidad (HDF), los suelos de parquet, la madera contrachapada curvada, los tableros de partículas chapados, los MDF chapados o los tableros de partículas.

Abstract: The present invention relates to a process for preparing a bonding resin, wherein lignin is provided in the form of an aqueous solution and mixed with one or more of glycerol diglycidyl ether, glycerol triglycidyl ether, sorbitol polyglycidyl ether, ethylene glycol diglycidyl ether, polyethylene glycol diglycidyl ether having 2-9 ethylene glycol units, propylene glycol diglycidyl ether having 1-3 propylene glycol units, and/or diglycidyl ether of terminal diol having a linear carbon chain of 3-6 carbon atoms; and optionally one or more additives. The bonding resin is useful for example in the manufacture of laminates, mineral wool insulation and wood products such as plywood, laminated veneer lumber (LVL), medium density fiberboards (MDF) , high density fiberboards (HDF) and particle boards.
