The invention relates to a preparation method for a high-
hardness water-based glass baking paint composed of nano water-based
acrylic resin, low-methoxylation amino resin, a water-based
polyurethane acrylic
hybrid, hardening resin, a colorant, a substrate
wetting agent, an
adhesive agent, an acid catalyst, a film-forming auxiliary agent, a defoaming agent, an anti-scratch flatting agent, a
thickening agent, a bactericide, a pH
regulator, a cosolvent and water. The prepared water-based glass baking paint has the advantages of low VOC, no
pollution to the environment, no poison and harm to operators, strong
coating film
adhesive force, good flexibility, high
hardness, excellent
wear resistance, excellent
water resistance, excellent
alcohol resistance, excellent salt
fog resistance, simple construction, and
stable storage. A prepared paint film has the
hardness reaching 5 H or more, and has anti-scratch and wear-resistance properties of a
ceramic glaze film; a prepared glass product achieves effects of blue and white porcelain, enamel
colored glaze porcelain, and white glazed porcelain; and the water-based glass baking paint is widely used for surface protection and decoration of
wine bottles, perfume bottles, glass products, lamps, woodware, metals, plastics and other products.
