▎ 摘  要

NOVELTY - Graphene modified aqueous elastic coating composition comprises 38-43 pts. wt. elastic emulsion, 13-18 pts. wt. titanium dioxide, 20-25 pts. wt. filler, 0.2-0.3 pts. wt. wetting agent, 0.5-0.6 pts. wt. dispersant, 0.1-0.2 pts. wt. neutralizing agent, 0.2-0.4 pts. wt. defoamer, 0.40-0.60 pts. wt. film-forming additive, 2.0-2.5 pts. wt. graphene aqueous solution, 15-30 pts. wt. water, and 0.5-1.0 pts. wt. thickener. The graphene aqueous solution has concentration of 1.2-1.4 mg/ml. USE - Graphene modified aqueous elastic coating composition. ADVANTAGE - The coating composition has strong texture, good weather resistance, water resistance, alkali resistance, and excellent stain resistance. It also has fireproofing and antibacterial functions. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene modified aqueous elastic coating composition by adding water into container; stirring at 400-600 revolutions per minute; sequentially adding dispersant, wetting agent, film-forming additive, defoamer, neutralizing agent and optionally portion of preservative; stirring for 1-2 minutes; further stirring at 700-900 revolutions per minute; sequentially adding titanium pigment and filler; stirring at 1000-1200 revolutions per minute; dispersing for 30 minutes at high speed; reducing stirring speed to 400-600 revolutions per minute; adding elastic emulsion, optionally remaining portion of preservative, and graphene water solution; stirring for stirring for 2-3 minutes; slowly adding thickener; adjusting viscosity to 15-16 mPa.s at 23 plus minus 2 degrees C; and further stirring for 15 minutes to obtain graphene modified aqueous elastic coating.
