The invention relates to nanometer high-weatherability colorful eco-friendly paint. The nanometer high-weatherability colorful eco-friendly paint comprises a
pigment component, a disperse medium and
varnish. The
pigment component comprises RO water
cellulose, an
emulsion, a dispersant,
pigment and
filling materials, a nanometer anti-aging agent, an antifoaming agent, a nanometer
stain-resistant agent, a film forming auxiliary agent, an antifreezing agent, an inorganic protection glue solution, a pH adjustment agent, a bactericide and a first
thickening agent. The disperse medium comprises RO water, a film forming auxiliary agent, a rheological agent, an
emulsion, an organic protection glue solution, an antifoaming agent, an inorganic protection glue solution and a
coupling agent. The
varnish comprises RO water, an
emulsion, a nanometer anti-aging agent, a pH adjustment agent, a bactericide, an antifoaming agent, a film forming auxiliary agent, an antifreezing agent and 0.3-1 part of a second
thickening agent. Compared with the prior art, the preparation method utilizes the nanometer
stain-resistant agent to reduce air organic dust adsorption, realize good
coating film self-cleanliness and improve paint
stain resistance and utilizes the nanometer anti-aging assistant to improve
aging resistance of the aqueous colorful paint.
