Beschreibung
Zusammenfassung:	The present invention relates to a process for preparing bonding resin, lignin in solid form or in the form of a dispersion in water is mixed with a crosslinker; and optionally one or more additives followed by addition of a basic solution. The bonding resin is useful for example in the manufacture of laminates, mineral wool insulation and wood products such as plywood, oriented strand board (OSB), laminated veneer lumber (LVL), medium density fiberboards (MDF), high density fiberboards (HDF), parquet flooring, curved plywood, veneered particleboards, veneered MDF or particle boards, laminates or mineral wool insulation. 本发明涉及制备粘合树脂的方法，将固体形式或在水中的分散体形式的木质素与交联剂和任选的一种或多种添加剂混合，然后添加碱性溶液。粘合树脂可用于例如以下的制造中：层合物、矿棉绝缘物和木制品，比如胶合板、定向刨花板(OSB)、层压单板木材(LVL)、中密度纤维板(MDF)、高密度纤维板(HDF)、镶木地板、曲面胶合板、贴面刨花板、贴面MDF或刨花板、层合物或矿棉绝缘物。
