Definitions
- the invention relates to a method for producing a binder liquor for wood-to-wood bonds from powdered binders or binder components which are brought into solution in a liquid.
- Wood Materials such as chipboard and fiberboard are produced by gluing wood chips or fibers with a binder and then drying them if necessary, sprinkling them into chip or fiber mats and then pressing them hot.
- Aminoplast resins such as urea and urea elamine-formaldehyde resins, phenol formaldehyde resins and adhesives based on polymeric diisocyanates are generally used as binders in the wood-based panel industry. To a small extent, tannin formaldehyde resins and starches in unmodified and modified form are also used as binders.
- Other binders based on renewable raw materials are lignins, proteins and carbohydrates, which are mainly used on their own or in combination with other binders in special plate types.
- the binders are mainly used in the wood-based materials as an aqueous glue liquor in the consistency range between 40-60%.
- powdered binders are processed either as an aqueous solution by the binder manufacturer or in the chip or fiberboard factories.
- the binders based on renewable raw materials are mainly delivered as powder to the particleboard and fiberboard plants, where they are dissolved in water and brought to the desired consistency.
- Additives can be added during the production of the binder liquor and the pH can be adjusted to the desired level.
- the invention is based on the object of producing a binder liquor which reduces water absorption and thickness swelling in wood-to-wood bonds, in particular in chipboard and fiberboard, in comparison to the products produced with conventional binder liquors.
- this object is achieved according to the invention in that wastewater used in the production of wood-based materials such as chipboard and fiberboard is used as the liquid.
- Waste water is to be understood primarily as the condensates that occur during the drying of wood chips and wood fibers, the waste water that arises in the manufacture of fiberboard using the wet process, and the squeeze water that occurs in the manufacture of fiberboard using the dry process.
- the squeeze water that occurs in large quantities in the production of medium-density fiberboard has a high chemical and biological oxygen demand, and therefore cannot be led into the drains and therefore requires special disposal.
- this waste water can be used directly in a recycling process for the production of binder liquors, the use of (pure) water being able to be dispensed with entirely.
- Further advantages are low swellings in thickness and water absorption, without adversely affecting the bending and transverse tensile strength of the plates produced with a binder liquor according to the invention.
- Tannin, starch, lignin, protein and mixtures thereof can be used as binders. It is expedient if the tannin to be used is obtained by extracting bark or wood with waste water from the wood-based materials industry.
