Embodiment 1

[0040] Under nitrogen protection and stirring, 100 g of xylene was added to a four-necked flask equipped with a condenser, a stirrer and a thermometer. After purging with nitrogen for 30 minutes, heat to 65°C. Then, a mixture of 0.1 g of mercaptopropylene glycol, 80 g of methyl methacrylate, 20 g of methacryloxypropyltrimethoxysilane, 1.5 g of azobisisobutyronitrile was added dropwise to xylene within 2 hours. middle. After the materials were added, the polymerization reaction was continued at 65° C. for 4 hours, and centrifuged at 800 rpm for 10 minutes to obtain an acrylic-based self-polishing resin.

[0041] Next, under the condition of nitrogen protection and stirring, 15g double moss melanin, 5g lysine diisocyanate, 10g poly 3-hydroxybutyrate, 70g acrylic-based self-polishing resin prepared in the previous step, 10g ethylene glycol Add alcohol and 0.5g triethylenediamine into xylene and react at 60°C for 1 hour to obtain an environmentally friendly long-acting self-secr...

Embodiment 2

[0043] Under nitrogen protection and stirring, 100 g of xylene was added to a four-necked flask equipped with a condenser, a stirrer and a thermometer. After purging with nitrogen for 30 minutes, heat to 100°C. Then, a mixture of 0.5 g of mercaptopropylene glycol, 70 g of methyl crotonate, 30 g of methacryloxypropyltrimethoxysilane, and 1.5 g of azobisisobutyronitrile was added dropwise to the second in solvent. After the materials were added, the polymerization reaction was continued at 100° C. for 24 hours, and centrifuged at 800 rpm for 10 minutes to obtain an acrylic-based self-polishing resin.

[0044] Next, under nitrogen protection and stirring conditions, 5g of 4-methoxycarbonyl-diorcin, 5g of lysine diisocyanate, 5g of poly 3-hydroxybutyrate, 80g of acrylic acid prepared in the previous step Based self-polishing resin, 10g of 1,4-butanediol, and 0.5g of triethylenediamine were added to xylene, and reacted at 90°C for 4 hours to obtain an environmentally friendly and...

Embodiment 3

[0046] Under nitrogen protection and stirring, 100 g of xylene was added to a four-necked flask equipped with a condenser, a stirrer and a thermometer. After purging with nitrogen for 30 minutes, heat to 90°C. Then, a mixture of 0.5 g of mercaptopropylene glycol, 20 g of methyl crotonate, 80 g of methacryloxypropyltrimethoxysilane, 1.5 g of benzophenone was added dropwise to the second solvent within 2 hours . After the materials were added, the polymerization reaction was carried out under the condition of ultraviolet light irradiation for 24 hours, and centrifuged at 800 rpm for 10 minutes to obtain an acrylic-based self-polishing resin.

[0047] Next, under nitrogen protection and stirring conditions, 5 g of cordycepin C, 5 g of toluene diisocyanate, 5 g of poly 3-hydroxybutyrate, 80 g of the acrylic-based self-polishing resin prepared in the previous step, 10 g of 1,4 -Butanediol and 0.5g of triethylenediamine were added to xylene and reacted at 80°C for 2 hours to obtai...

Abstract

The invention relates to environment-friendly long-acting self-secretion anti-corrosion paint and a preparation method thereof. The environment-friendly long-acting self-secretion anti-corrosion paint is prepared from aromatic environment-friendly preservatives, degradable polypolyol, diisocyanate, acrylic acid based self-polishing resin, chain expanding agents, catalysts and a first solvent. The anti-corrosion paint optionally contains urethane acrylate. The anti-corrosion paint has the advantages that an environment-friendly effect is achieved; during ship navigation and ship stop, preservatives can be peeled off by self through hydrolysis and can be slowly and uniformly released; the dependence on ship navigation speed is reduced; the long-acting anti-corrosion effect can be achieved on ships, submarines, offshore production platform facilities and the like. A process for preparing the environment-friendly long-acting self-secretion anti-corrosion paint is simple, and is applicable to industrial production.

Description

technical field [0001] The invention relates to the field of anticorrosion coatings for marine structures and ships. Specifically, the invention relates to an environment-friendly long-acting self-secreting anticorrosion coating and a preparation method thereof. Background technique [0002] Seawater is a natural dielectric solution with a variety of salts, and there are various marine organisms in seawater. Some marine organisms can aggravate the corrosion rate of steel, so reducing or even eliminating the corrosion of marine structures caused by marine organisms has always been a difficult problem in the industry . [0003] Applying anti-corrosion coatings to marine structures is currently the most cost-effective method for eliminating corrosion of marine structures caused by marine organisms. However, the current mainstream self-polishing anti-corrosion coatings still need to use cuprous oxide anti-corrosion agents. Some anti-corrosion coatings even need to use organot...
