The invention discloses a low-cost
energy storage luminescent paint and a preparation method thereof. The low-cost
energy storage luminescent paint is prepared from, by weight, 30-50 parts of silicondioxide microspheres, 2-3 parts of a
coupling agent, 20-30 parts of luminous
powder, 10-25 parts of
polyvinyl alcohol, 15-25 parts of an
acrylic acid emulsion, 10-20 parts of a
styrene-acrylic
emulsion, 0.5-1 part of a
wetting agent, 1-5 parts of dihydroxypropane, 0.1-0.2 part of an antifoaming agent, 0.05-2 parts of a dispersing agent, 0.2-0.5 part of talcum
powder, 0.1-0.5 part of a
water repellent, 0.1-0.5 part of a coalescing agent, 0.1-0.5 part of a
thickening agent, 0.1-0.5 part of a pH adjuster and 10-15 parts of water. The low-cost
energy storage luminescent paint and the preparation method thereof have the advantages that fluorescent
powder is embedded in the
silicon dioxide microspheres, and the surfaces of the
silicon dioxide microspheres are modified with the
polyvinyl alcohol,so that not only is the luminous efficiency of the fluorescent powder improved, but also the stability of the fluorescent powder is improved, the service life and lighting time of the paint are prolonged, the environmental friendliness is achieved, the brightness of the
coating is high, the persistence time is long, the adhesion and
corrosion resistance are good, and the application prospects aregood.
