METHOD FOR PRODUCING A BINDER COMPOSITION, A BINDER COMPOSITION, AN ADHESIVE COMPOSITION, A LAYERED COMPOSITE STRUCTURE, AND USES OF THE BINDER COMPOSITION AND THE ADHESIVE COMPOSITION |
摘要 |
The invention relates to a method for producing a binder composition, wherein the method comprises the following steps: (i) forming an aqueous composition comprising reactant components including lignin, a polymerizable substance and a crosslinking agent in the presence of a catalyst; (ii) cooking the formed composition until the composition has a viscosity, which corresponds to 45-95% of a predetermined viscosity value of the final binder composition; (iii) adding tannin as a reactant component to the composition; and (iv) cooking the composition at a temperature of 60-95° C. for polymerizing the reactant components until a binder composition with a predetermined viscosity value is formed. |
