Binder for wood-based panels comprising amino acid polymer and polyaldehyde compound

Abstract

The invention relates to a process for producing a lignocellulosic composite comprising one or more lignocellulosic composite layers. The process comprises S1) providing or preparing a mixture, at least comprising: lignocellulosic particles and a binder composition, the binder composition comprising as components at least: c1) one or more amino acid polymers having two or more primary amino groups and c2) one or more polyaldehyde compounds. The process further comprises S2) compacting the mixture from step S1) to receive a compacted mixture, and S3) applying heat and optionally pressure to the compacted mixture from step S2), so that the binder of the binder composition hardens and a lignocellulosic composite results. The invention further relates to the use of the lignocellulosic composite. Moreover, the invention relates to a kit for producing a binder composition, for use in the production of a lignocellulosic composite, and to the use of such binder composition.
