This application discloses a water-based sand texture paint and its preparation method, belonging to the field of water-based paint technology. The water-based sand texture paint of this application, based on 100% of the total
mass of the water-based sand texture paint, includes: 1-1.5% mixed
corrosion inhibitor, 1.5-3.5% film-forming aid, 10-15% water-soluble
acrylic resin, 15-20% hydroxyl acrylic dispersion, 10-15%
polyurethane dispersion, 10-15% precipitated
barium sulfate, 10-15% glass micro
powder, 0.2-0.5%
coupling agent, 0.2-0.3%
wetting agent, 0.3-0.5% dispersant, 0.1-0.3%
defoamer, 5-10% color paste, 0.2-0.5%
bentonite, 0.3-2.5% thickener, 5-7% sand texture
powder, 8-10% expanded
graphite, 0.5-1.5% activation period
extender, and 15-20% water. The water-based sand texture paint prepared using the formula and preparation method of this application has a low
odor during the
coating process, is non-flammable and non-explosive, and has
low toxicity, making it more suitable for widespread use, especially for use in the luggage compartment of passenger cars, with a wide range of applications.
