Beschreibung
Zusammenfassung:	The invention discloses waterborne polyurethane modified montmorillonite nanometer composite emulsion with high water resistance, and belongs to the field of organic-inorganic nanometer composite emulsion. Intercalation modification is carried out on montmorillonite by the aid of acid dissociation polyether amine. Interlayer sodium ions in the montmorillonite are substituted by ammonium ions, andaccordingly the interlayer spacing of the montmorillonite can be increased; groups with isocyanate reaction activity are led into the montmorillonite, then reaction is carried out on formed intercalation-modified organic montmorillonite solution and polyurethane to prepare the waterborne polyurethane modified montmorillonite nanometer composite emulsion which is waterborne polyurethane and montmorillonite nanometer composite emulsion. The waterborne polyurethane modified montmorillonite nanometer composite emulsion has the advantages that the waterborne polyurethane modified montmorillonite nanometer composite emulsio
