The embodiment of the invention discloses a water-based
coating composition. The water-based
coating composition is prepared from, by weight, 60-90 parts of acrylic
emulsion, 3-12 parts of a film-forming auxiliary, 0.2-0.5 part of
defoamer, 0.3-0.6 part of a base material
wetting agent, 4-25 parts of a scratch-resistant agent, 0.4-0.8 part of
accelerant, 0.4-1 part of a flatting agent, 0.1-0.5 part of a pH conditioning agent and 0.2-0.5 part of an
antiseptic antimildew agent. According to the water-based
coating composition, scratch resistance,
alcohol resistance,
water resistance and
stain resistance of a paint film are excellent,
adhesive force on a commonly used substrate is good, the water-based coating composition is rapid to dry, resistant to a high temperature, not prone to after-tack and
environmentally friendly, coating of the composition on a product can be realized through various operation
modes without a curing agent, the paint film formed after coating is conducted is high in density and
hardness and resistant to
impact of heavy objects, an
aqueous solution or other commonly used liquid does not permeate into the paint film easily, and the water-based coating composition is suitable for
surface coating of various types of bamboo and wood furniture and artware.
