Abstract

La présente invention concerne un procédé de préparation de colles urée-formaldéhyde et les colles ainsi obtenues. Selon l'invention, on mélange un sel inorganique à une source de formaldéhyde, on chauffe et on fait réagir avec de l'urée pour provoquer un début de polymérisation en milieu. acide, on arrête la réaction de polymérisation lorsque le mélange a atteint la viscosité désirée, on refroidit le mélange, on ajoute de l'urée au mélange au cours du refroidissement et on obtient la colle après refroidissement. Les colles obtenues sont utiles à la fabrication de panneaux de bois agglomérés ou contreplaqués.
