Abstract

The invention discloses a thermosetting amino-acid resin coating. Raw materials of the thermosetting amino-acid resin coating comprise, by weight, 100 parts of a thermosetting amino-acid resin composition, 35-50 parts of an aluminum-magnesium-zinc alloy pigment, 10-12 parts of an amino acid salt, 3-5 parts of an auxiliary solvent, 0.5-2 parts of an auxiliary agent, 0-1 part of a curing agent and 30-35 parts of water, wherein the thermosetting amino-acid resin composition comprises, by weight, 50 parts of methanol, 35-50 parts of hexamethylolmelamine, 15-18 parts of sodium glutamate or sodium aspartate, 3-5 parts of ammonium sulfamate, ammonium p-toluenesulfonate or ammonium tartrate, 40 parts of a mixture obtained by mixing wollastonite and talcum powder according to a ratio of 3:1, 50-65 parts of propyleneglycol monomethyl ether and 1.5 parts of diethanolaniline. The thermosetting amino-acid resin coating has good storage stability, good thermosetting property and good water resistance; a reaction temperature is low; and a reaction time is short.

Description

technical field [0001] The invention relates to an amino acid resin coating, in particular to a thermosetting amino acid resin coating. Background technique [0002] At present, the application of industrial coatings in the world is mainly based on solvent-based coatings. However, with the continuous improvement of environmental protection awareness in various countries, the restrictions on the use of organic solvents have also put forward higher and higher requirements. [0003] Amino acid resin coatings are widely used in anti-corrosion coatings, electrical insulation coatings, food can inner wall coatings and other fields because of their advantages such as strong adhesion, excellent chemical corrosion resistance, small shrinkage, wear resistance and good insulation. However, its disadvantages are that the reaction temperature is high and the time is long, and the thermosetting and water resistance are not good.
