Abstract[English]
Disclosed is a water-based hardener component and adhesive composition includes a hardener component, and adhesive component and 10-60 wt% of water. The hardener component includes a 4-35 wt.% of at least one first acid with pKa in the interval of 2.5-10, the first acid is at least one selected from formic acid (CH2O2), glycolic acid (C2H4O3), malic acid (C4H6O5), or a combination thereof, and 0.05-15 wt.% of at least one second acid with a pKa in the interval of 0.8-2.4, the second acid is at least one selected from pyrophosphoric acid (H4P2O7), sulfamic acid (H2NSO3H), hypophosphorous acid (H3PO2), phosphoric acid (H3PO4), or a combination thereof. The adhesive component includes a resin having a functional amino groups. The water-based hardener component and adhesive composition is used for structural timber product.[French]
L'invention divulgue un constituant durcisseur à base d'eau et une composition adhésive comprenant un constituant durcisseur et un constituant adhésif et 10 à 60 % en poids d'eau. Le constituant durcisseur comprend 4 à 35 % en poids d'au moins un premier acide présentant un pKa dans l'intervalle de 2,5 à 10, le premier acide est au moins un acide choisi parmi l'acide formique (CH2O2), l'acide glycolique (C2H4O3), l'acide malique (C4H6O5) ou une combinaison correspondante, et 0,05 à 15 % en poids d'au moins un second acide présentant un pKa dans l'intervalle de 0,8 à 2,4, le second acide est au moins un élément choisi parmi l'acide pyrophosphorique (H4P2O7), l'acide sulfamique (H2NSO3H), l'acide hypophosphoreux (H3PO2), l'acide phosphorique (H3PO4), ou une combinaison correspondante. Le constituant adhésif comprend une résine présentant un groupe amino fonctionnel. Le constituant durcisseur à base d'eau et la composition adhésive sont utilisés pour un produit structural en bois.
