The disclosure relates to an adhesive composition for bonding lignocellulosic substrates. The adhesive composition contains a crosslinker and a non-urea diluent where the non-urea diluent is present in an amount from about 0.01 to about 75 weight % based on the total wet weight of the composition and where the crosslinker contains essentially no formaldehyde. Also disclosed is the adhesive further containing, an aqueous mixture of a protein source. The disclosure also relates to a process for making lignocellulosic composites utilizing the disclosed adhesive composition and to the lignocellulosic composites made using the disclosed process.
L'invention porte sur une composition adhésive pour le collage de substrats lignocellulosiques. La composition adhésive contient un réticulant et un diluant non-urée, le diluant non-urée étant présent en une quantité d'environ 0,01 à environ 75 % en poids sur la base du poids humide total de la composition et le réticulant ne contenant sensiblement pas de formaldéhyde. L'invention porte également sur un adhésif contenant en outre un mélange aqueux d'une source de protéine. L'invention porte également sur un procédé de fabrication de composites lignocellulosiques utilisant la composition adhésive décrite et sur les composites lignocellulosiques obtenus à l'aide du procédé décrit.
