NOVELTY - An aqueous paint containing ultra hydrophobic composite cellulose acetate nano fiber, comprises 40-50 pts. wt. aqueous acrylic resin emulsion with solids content of 40-50%, 4-5 pts. wt. cellulose acetate, 0.1-0.2 pts. wt. polysiloxane, 0.1-0.2 pt. wt. graphene oxide, 0.1-0.2 pt. wt. polyoxyethylene alkyl ether, 0.1-0.2 pt. wt. silicone defoamer, 12-15 pts. wt. N,N-dimethylformamide, 35-40 pts. wt. acetone, deionized water and 0.01-0.02 pt. wt. ammonia. USE - Aqueous paint containing ultra hydrophobic composite cellulose acetate nano fiber for wooden handicraft. ADVANTAGE - The aqueous paint has excellent hydrophobicity, smooth surface and high practicability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation of aqueous paint containing ultra hydrophobic composite cellulose acetate nano fiber, which involves mixing cellulose acetate, polysiloxane, graphene oxide, N,N-dimethylformamide and acetone to form composite solution, stirring until completely dissolved in aqueous ammonia, heating at 50-60 degrees C, stirring and mixing for 30-40 minutes to prepare mixed solution, spinning at voltage of 10-12 kV, receiving distance of 15-20 cm, injection rate of 1-1.5 mL/hour, adding deionized water, stirring at 400-500 rpm, centrifuging, washing, drying to obtain composite cellulose acetate nanofibers, adding aqueous acrylic emulsion and other additive, adjusting viscosity, defoaming and sieving to obtain final product.
