Abstract

The invention relates to a binder for producing materials based on wood chips and/or wood fibers. The aim of the invention is to design a binder which is used for producing and gluing materials based on wood chips and/or wood fibers, contains natural protein components, significantly reduces or even eliminates the drawbacks of the prior art, and can be economically produced and used. Said aim is achieved by a binder which is used for materials based on wood chips and/or wood fibers, comprises an aldehyde-based condensation resin and other additives, and is characterized in that the binder comprises a water-soluble reactive additive containing a peptide/amino acid mixture without moieties of water-insoluble and high-viscosity proteins. The invention also relates to a method for producing said binder as well as a molded article.
