specific Embodiment approach 1

[0011] Specific embodiment one: In this embodiment, the alkyd resin is composed of 6.01 to 6.38 moles of trimethylolpropane, 2.30 to 2.79 moles of carboxyl substances, and 2.30 to 2.79 moles of carboxyl substances. 0.90-1.23 moles of adipic anhydride and 0.90-1.29 moles of isononanoic acid are used.

specific Embodiment approach 2

[0012] Specific embodiment two: The difference between this embodiment and specific embodiment one is that the alkyd resin consists of 6.2 moles of trimethylolpropane, 2.4 moles of phthalic anhydride and carboxyl substances in the alkyd resin Adipic anhydride in an amount of 1.2 moles and isononanoic acid in an amount of 1.2 carboxyl species. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0013] Specific embodiment three: the preparation method of the present embodiment alkyd resin is as follows:

[0014] One, the amount of taking hydroxyl substances is 6.01~6.38 moles of trimethylolpropane, the amount of carboxyl substances is 2.30~2.79 moles of phthalic anhydride, the amount of carboxyl substances is 0.90~1.23 moles of adipic anhydride and The amount of carboxyl substance is isononanoic acid of 0.90~1.29;

[0015] 2. Put isononanoic acid, trimethylolpropane, phthalic anhydride and adipic anhydride into the reaction kettle, pass through N2 to raise the temperature to 85-100°C, start stirring, and then use 70-85°C / h Raise the temperature to 165±5°C, release the water produced by the reaction, raise the temperature to 210±5°C, react until the acid value is 18-20KOH mg / g, stop the reaction, cool down to 150°C, and then add solvent to dilute to the mass concentration 45%, to obtain alkyd resin, wherein said solvent is made up of 200# gasoline, trimethylbenzene an...

Abstract

The invention provides an alcohol acid resin, a preparation method of the alcohol acid resin and an anti-corrosion paint using the alcohol acid resin, relates to an anti-corrosion paint, and aims to solve the technical problem of workpiece surface rusting corrosion caused by corrosion of equipment surface due to processing solution and air. The alcohol acid resin is prepared by trimethylolpropane, phthalic anhydride, adipic acid anhydride and isononanoic acid. The anti-corrosion paint using alcohol acid resin consists of alcohol acid resin, ethenyl resin, ethenyl triethoxysilane and dryer W-2000B. The anti-corrosion paint provided by the invention is excellent in physical and chemical properties, namely a coat film has no change since being subjected to salt mist for 100h, the coat film has no change since being subjected to water for 360h, the coat film de-colors lightly since being subjected to manual aging for 100h, and the compact is 50Kgcm, the toughness is 1mm, and the adhesive force is of 1 grade.

Description

technical field [0001] The invention relates to an anticorrosion coating. Background technique [0002] During the manufacturing, transportation, and storage of power station equipment, the surface of the equipment is corroded by processing fluids and the atmosphere, which will cause serious corrosion on the surface of the workpiece. Especially in the process of sea transportation, seawater erosion is more serious, resulting in equipment surface corrosion. Contents of the invention [0003] The purpose of the present invention is to solve the technical problem that the surface of the equipment is corroded by the machining fluid and the atmosphere, and to provide a kind of alkyd resin, a preparation method of the alkyd resin and an anti-corrosion coating using the alkyd resin. [0004] The alkyd resin is composed of trimethylolpropane with 6.01-6.38 moles of hydroxyl substances, phthalic anhydride with 2.30-2.79 moles of carboxyl substances, adipic anhydride with 0.90-1.23...
