Abstract

The invention discloses a water-based acrylic amino baking varnish for making barrels and a preparation method thereof. The water-based acrylic amino baking varnish for making barrels comprises the following components in parts by mass: 20-40 parts of epoxy modified acrylic resin, 2-5 parts of methyl etherified high imino melamine resin, 2-5 parts of hexamethoxymethyl melamine resin, 3-5 parts ofa cosolvent, 1-2 parts of blocked aqueous isocyanate, 1-3 parts of a pH adjuster, 0.2-0.4 part of a de-foaming agent, 0.5-1.5 parts of dispersant, 0.3-0.5 part of a substrate wetting agent, 20-30 parts of deionized water, 0.2-0.4 part of a flatting agent, and 3-30 parts of pigment. The baking varnish has high gloss, high decorativeness, excellent hardness, good solvent resistance and weather resistance, low VOC content and very low odor.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based acrylic amino baking varnish for barrel making and a preparation method thereof. Background technique [0002] Traditional barrel paints generally use solvent-based coatings, and the dispersion medium of solvent-based coatings is organic solvents (generally referred to as VOC). Most of the organic solvents volatilized from the coating film are toxic and harmful substances, which not only cause harm to the human body, And it will pollute the natural environment. The invention is a water-based paint, which uses tap water as a diluent, belongs to non-hazardous chemicals, and has the characteristics of safety, environmental protection and non-toxicity. The use of water-based products not only enables users to protect employees' bodies from harmful solvents during coating construction, but also reduces users' harm to the environment, reduces the discharge of harmful ex...
