Title
(EN) SOLVENT-FREE SINGLE-COMPONENT MOISTURE-CURING POLYURETHANE ADHESIVE FOR USE ON WOOD AND PREPARATION METHOD THEREFOR
(FR) ADHÉSIF DE POLYURÉTHANE DURCISSANT À L'HUMIDITÉ, MONOCOMPOSANT ET SANS SOLVANT DESTINÉ À ÊTRE UTILISÉ SUR DU BOIS ET PROCÉDÉ DE PRÉPARATION ASSOCIÉ

Abstract
(EN) A solvent-free single-component moisture-curing polyurethane adhesive for use on wood and a preparation method therefor. Calculating by mass percentage, the raw material formula of the polyurethane adhesive comprises the following components: an isocyanic acid 45.6-58%, a polyether polyol 18.7-30%, a polyester polyol 20-27%, a catalyst 0.1-0.3%, and an auxiliary 0.1-0.3%. The polyether polyol is a mixture of a propylene oxide polyether polyol having a functionality of 3 and a number average molecular weight of 5,000-6,000, a random copolymer polyether polyol of ethylene oxide and propylene oxide, and a polytetrahydrofuran ether polyol having a functionality of 2 and a number average molecular weight of 1,000-2,000. The polyol in the polyurethane adhesive utilizes a specific combination of a polyether polyol and a polyester polyol. The polyurethane adhesive obtained by the present preparation is used as an adhesive between pieces of wood, has a high compression shear strength, and allows for wood durability.
(FR) L'invention concerne un adhésif de polyuréthane durcissant à l'humidité, monocomposant, sans solvant destiné à être utilisé sur du bois et un procédé de préparation associé. Calculée en pourcentage en masse, la formule de matière première de l'adhésif de polyuréthane comprend les composants suivants : 45,6-58 %, d'un acide isocyanique, 18,7-30 % d'un polyéther polyol, 20-27 % d'un polyester polyol, 0,1-0,3 % d'un catalyseur et 0,1-0,3 %. d'un ajduvant Le polyol de polyéther est un mélange d'un polyéther polyol d'oxyde de propylène ayant une fonctionnalité de 3 et un poids moléculaire moyen en nombre de 5 000 à 6 000, d'un copolymère statistique de polyéther polyol d'oxyde d'éthylène et d'oxyde de propylène, et un éther polyol de polytétrahydrofurane ayant une fonctionnalité de 2 et un poids moléculaire moyen en nombre de 1 000 à 2 000. Le polyol dans l'adhésif de polyuréthane utilise une combinaison spécifique d'un polyéther polyol et d'un polyester polyol. L'adhésif de polyuréthane obtenu par la présente préparation est utilisé comme adhésif entre des morceaux de bois, a une résistance élevée au cisaillement en compression, et permet une durabilité du bois.
