Abstract

The invention relates to the preservative coating technology, in particular to a water-based two-pack polyurethane preservative coating and a preparation method thereof. The water-based two-pack polyurethane preservative coating comprises two parts, namely paint vehicle and curing agent, wherein the paint vehicle is prepared from water-based hydroxylated acrylic dispersion, modified resin, pigment, filler, additive and water, the curing agent part comprises hydrophilic aliphatic isocyanate, dodecyl ester and propylene glycol methyl ether acetate. When using the coating of the invention, the weight ratio of the paint vehicle to the curing agent is 74-85:15-26 and the coating can solve the defects of the existing preservative coating.

Description

technical field

[0001] The invention relates to anticorrosion paint technology, in particular to a water-based two-component anticorrosion paint and a preparation method thereof. Background technique

[0002] In order to purify the living environment of human beings, the strict restrictions on the content of volatile organic compounds (VOC) in coating systems by the environmental protection laws of various countries have promoted the development of low-pollution coatings represented by water-based coatings. Since Bayer first created the aliphatic isocyanate curing agent in 1985, polyurethane coatings around the world have developed rapidly. Polyurethane coatings can be widely used in surface decoration of leather, furniture, automobiles, aircraft, and various steel structures. At present, most polyurethane coatings are still mainly solvent-based. Water-based polyurethane coatings are firstly applied in the surface decoration of wooden furniture and leather finishing in China...
