▎ 摘  要

NOVELTY - Graphene additive comprises 33-45 pts. wt. styrene-acrylic emulsion, 20-28 pts. wt. silica sol, 5-10 pts. wt. methyl silica gel, 2-6 pts. wt. aluminum sulfate, 2-10 pts. wt. graphite, 4-8 pts. wt. active diluent, 5-10 pts. wt. silver ion, 1-5 pts. wt. photocatalytic oxide, 2-6 pts. wt. p-nitrophenol, 40-50 pts. wt. water and 1-5 pts. wt. defoamer. USE - Graphene additive used for latex paint (claimed) useful in the field of architectural decoration. ADVANTAGE - The graphene additive provides latex paint, which has the function of purifying harmful gas such as formaldehyde. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene additive comprising mixing graphene, active diluent and defoamer to obtain graphene slurry, mixing graphene slurry, styrene-acrylic emulsion, silica sol, methyl silica gel, aluminum sulfate, photocatalytic oxide, p-nitrophenol, and defoamer, ball milling for 60-70 minutes, adding water, raising the temperature to 45 degrees C and stirring for 50-60 minutes, adding silver ion, sealing and stirring for 50-60 minutes at room temperature.
