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.
