More Information
Summary:The invention discloses a preparation method of waterborne nano slurry. The method takes polyol as bridge group to firstly modify the surface of the nano particle, increases hydroxyl groups on the surface of the nano particle, improves the dispersity of the nano particle in water medium, and then adopts ball milling technology in the water medium to implement modification of silane coupling agentto directly prepare dispersed and stable waterborne nano concentrated slurry with the concentration of 80-100g/L. The slurry after dilution can be directly used for after finishing process of textiles, thereby endowing the textiles with firm nano function. The preparation method solves the dispersion problem and the binding problem with fabric of nano powder in textile field application at present, thereby expanding the application of nano materials in textile field.
