Abstract
Described herein is a process for producing a lignocellulosic composite, a binder composition suitable for use in said process, as well as a lignocellulosic composite which can be produced by the process of the invention, and its use. Moreover is described herein a kit for producing a binder composition for use in the production of a lignocellulosic composite and a respective use of such binder composition.
Claims16
A binder composition for producing a lignocellulosic composite, wherein the binder composition comprises as components at least:
- c1) one or more amino acid polymers having two or more primary amino groups, wherein the one or more amino acid polymers comprise or are one or more polylysines, wherein
- the one or more polylysines have a weight-average molecular weight Mw of ≥800 g/mol and
- comprise as monomers integrated in their polymer structure at least 85 mass-% of lysine monomers, based on the total mass of the polymer structure;
- c2) one or more alpha-hydroxy carbonyl compounds, wherein components c1) and c2) are a binder;
- and
- c3) one or more basic substances having a pKB-value of ≤3.
