Problems solved by technology

[0002] Metal anti-corrosion coatings are composed of resins, pigments, additives and solvents. The performance of the coatings and the solvent used to dilute them during use are mainly determined by the resins. At present, the resins used for metal anti-corrosion coatings are mostly polyurethane resins and acrylate resins. And alkyd resin, etc., most of them use benzene as solvent, which is not only expensive, but also causes great environmental pollution during production and use.
[0003] At present, mature alcohol-soluble resins that can produce metal anti-corrosion coatings include: alcohol-soluble polyurethane resin and polyvinyl acetal resin. These types of resins are relatively expensive due to raw material costs and production processes. Its cost is high, so reducing the cost of alcohol-soluble resin has become an urgent demand of the market

Embodiment 1

[0053] The preparation of embodiment 1 alcohol-soluble resin used in the present invention

[0054] Equipment: The equipment required by the present invention is: reactor, which is equipped with agitator, reflux condenser, stainless steel dropping tank, heating and temperature controller.

[0055] ①. Add 30 kg of vinyl acetate, 4 kg of methyl acrylate, and 10 kg of isopropanol as a diluent into the reaction kettle together, heat up and stir.

[0056] ②. 30 kg of vinyl acetate, 4 kg of methyl acrylate, 20 kg of methyl methacrylate, 5 kg of methacrylic acid, 2 kg of hydroxypropyl acrylate, 5 kg of glycidyl methacrylate, azobisisobutyronitrile 0.6 kg is added to the drop-adding tank as component B. When the temperature of the material in the kettle rose to the reflux temperature, it was dropped into the kettle within 2 hours, and then reacted for 1 hour.

[0057] ③. After dissolving 0.2 kg of azobisisobutyronitrile in 5 kg of ethyl acetate, drop it into the kettle within 0.5 ho...

Embodiment 2

[0059] Embodiment 2 Alcohol-soluble metal anticorrosion coating preparation of the present invention

[0060] The formula of producing metal anticorrosion paint with resin of the present invention is as follows (weight ratio):

[0061] 50 parts of resin solution prepared by embodiment 1

[0062] Titanium dioxide 15 parts

[0063] 0.8 parts of defoamer
