▎ 摘　　要

NOVELTY - Indoor emulsion paint comprises 20-40 pts. wt. acrylic emulsion, 10-25 pts. wt. ammonia water, 2-4 pts. wt. nano-ferric oxide, 2-4 pts. wt. nano-titanium dioxide, 2-4 pts. wt. graphene, 4-8 pts. wt. negative ion powder, 15-30 pts. wt. protein, 4-8 pts. wt. polyvinyl alcohol, 6-14 pts. wt. maleic anhydride, 4-8 pts. wt. chitosan, 5-7 pts. wt. epoxy chloropropane, 2-4 pts. wt. nano-silicon dioxide, 5-10 pts. wt. self-made pigment filler and 4-8 pts. wt. self-made film-forming agent. USE - Used as indoor emulsion paint. ADVANTAGE - The indoor emulsion paint with strong stain resistance and scrub resistance. The scattering and reflection effects of the two different particle diameters of the nano-material are different, generating different color effect along with the incident light angle, and releasing negative ions. The resonance of the graphene also can accelerate the release of the negative ions. The hydrophilicity of polyvinyl alcohol is increased and the water absorption is reduced, releasing more negative ions. After adding epoxychloropropane and nano-silicon dioxide, the pigment filler is more firmly locked in the latex paint. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the indoor emulsion paint comprising preparation of self-made pigment filler, preparation of self-made film-forming agent, and preparation of the emulsion paint.
