Abstract

The invention discloses an aqueous polyester resin paint. The aqueous polyester resin paint comprises polyol, polybasic acid, 8-16% of catalyst, 6-12% of a curing agent, 6-10% of a filler and 60-80% of water; the polyol comprises 8-12% of trimethylolpropane, 12-24% of neopentyl glycol, 6-12% of ethylene glycol and 8-12% of propylene glycol, and the polybasic acid comprises 5-15% of purified terephthalic acid, 12-24% of m-phthalic acid, 6-12% of phthalic acid, 10-18% of trimellitic anhydride, 6-12% of hexahydrophthalic acid, 10-20% of maleic anhydride and 5-10% of adipic acid; and the aqueous polyester resin paint also includes 0.1-0.3% of p-methoxyphenol, 6-24% of ethylene glycol monobutyl ether, 8-16% of dimethylethanolamine and 60-100% of deionized water. The aqueous polyester resin paint improves the stability of the hydrolysis of a polyester main chain in order to improve the aqueous insulation property of the polyester resin paint, can be widely used in aqueous insulation devices, and meets practical use requirements.

Description

technical field [0001] The invention relates to a water-based polyester resin paint and a preparation method thereof, belonging to the technical field of synthetic paints. Background technique [0002] In recent years, water-based environmentally friendly coatings, including high-solid and solvent-free coatings, water-based coatings, powder coatings and radiation-cured coatings, have achieved rapid development. Water-based polyester coating, one of the representative water-based coatings, has the characteristics of high gloss, strong adhesion, high fullness, and excellent impact resistance. It can be formulated with water-soluble amino resin to make water-based baking paint, and can also be used Hydrophilic polyisocyanate is formulated into water-based wood coatings cured at room temperature, so it is widely used in the protection and decoration of metal and wood surfaces; because polyester is easy to hydrolyze, the application of water-based polyester is limited to a certai...
