The invention discloses an
ultraviolet-resistant anti-aging water-based paint for external walls. The invention is characterized in that the water-based paint is prepared from the following raw materials in parts by weight: 28-30 parts of pure acrylic
emulsion, 9-11 parts of water-based
polyurethane resin, 3-5 parts of granite
powder, 4-6 parts of precipitated
barium carbonate, 0.8-1 part of 2-hydroxy-4-methoxy
diphenyl ketone, 4-6 parts of
silicon dioxide, 3-5 parts of paper clay, 2-3 parts of
ethylene tar, 1-1.5 parts of dispersing agent NNO, 6-8 parts of modified round-grain
mortar and 25-30 parts of water. By adopting the special formula and combining the sand wall paint and
ultraviolet-resistant paint, the 2-hydroxy-4-methoxy
diphenyl ketone has
ultraviolet absorption effect; and by adding the modified round-grain
mortar, the water-based paint has the advantages of favorable dispersion effect, high
hardness and favorable
wear resistance. The coated film has the advantages of beautiful
tactile sensation, light weight, favorable
dispersity, favorable adhesiveness and elegant appearance, can not increase the pressure of the building, and can satisfy different decoration demands.
