Abstract
(EN) The present application describes an adhesive that is in the form of a solid coacervate made of compounds that can be obtained from agroindustrial waste, particularly cellulose and lignosulphonate. The cellulose used in the composition is nanofibrillated or nanocrystalline cellulose, preferably nanofibrillated cellulose. A method for producing said adhesive coacervate is also described.
(FR) L'invention concerne un adhésif se présente sous la forme d'un coacervat solide, constitué de composés pouvant être obtenus à partir de déchets agro-industriels, notamment de cellulose et de lignosulfonate. La cellulose utilisée dans la composition est la cellulose nanofibrillée ou nanocristalline, de préférence nanofibrillée. L'invention concerne également un procédé d'obtention de ce coacervat adhésif.
