Research on Coating Dispersion of Liquid Wear-Resistant Decorative Paper

Abstract:

Liquid wear-resistant technology combines original decorative paper and the surface wear-resistant paper into one. Wear-resistant particles are coated directly on the surface of base decorative paper, forming a transparent wear-resistant protective layer. The suspension behavior of ultra-fine A1₂O₃ in the aqueous phase was investigated. The aim was further realizing the good consistency among A1₂O₃, melamine resin and other components. The main influencing factors [viz., dispersant type, dispersant dosage, dispersive methods and pH value] were investigated to get the optimum conditions. The results showed that the stable aqueous suspension of ultrafine A1₂O₃ could be obtained under the following conditions: the concentration of superfine A1₂O₃ 5wt%, pH = 9, anionic dispersant APAAA, the amount of dispersant 0.4wt%, ultrasonic suspension time 30min.
