At present, the most used anti-corrosion coating is fluorocarbon topcoat, which has many advantages such as strong adhesion, good corrosion resistance and anti-aging performance, but this kind of fluorocarbon topcoat is expensive and expensive, and cannot meet the requirements Market high gloss requirements
There are also some paints used for spraying on metal surfaces in the prior art, but the effect of spraying is not ideal, and there are defects such as poor appearance quality, easy scratches, easy wear damage, dull luster, and poor outdoor weather resistance, which affects the metal plate.

Embodiment Construction
[0007] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments.
[0008] The reaction process is as follows: epoxy amide resin solution is synthesized with epoxy resin and propionamide, and acrylic acid monomer, initiator and epoxy amide resin solution are grafted; new acrylic resin is used as base material, and fillers and various additives are added. agent, disperse until the fineness is acceptable, add amino resin and leveling agent, then dilute with solvent and stir until the acceptable viscosity.
[0009] After testing, this kind of coating not only has good anti-corrosion performance of epoxy, but also has excellent acid and alkali resistance, and can effectively protect steel in some storage tank anti-corrosion, sewage pipelines, chemical plant pipelines and other fields. The present invention soaks 20wt% hyd...

The invention discloses a preparation method of a high-chemical-resistance acrylic acid finish coat. Epoxy resin, acrylonitrile and acrylic acid have grafting reaction under the catalytic effect of BPO to synthesize resin, and then the synthesized resin is taken as a main film forming substance to prepare an acrylic acid coating. The coating has good corrosion resistance of epoxy and also has excellent acid resistance and alkali resistance, and can be used for effectively protecting steel materials in some fields such as anti-corrosive sewage pipelines of storage tanks and pipelines of chemical plants. By adopting the high-chemical-resistance acrylic acid finish coat, a plate surface is free of any phenomenon of bubbling and peeling after being soaked in 2wt% hydrochloric acid, 20wt% sodium hydroxide and 60wt% sulfuric acid for half a year; the high-chemical-resistance acrylic acid finish coat is good in film forming property and stable in storage.
Description
technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a preparation method of a highly chemical-resistant acrylic topcoat. Background technique [0002] Among all kinds of anti-corrosion technologies and measures, the use of paint anti-corrosion is the simplest and most effective method, which is widely used. At present, the most used anti-corrosion coating is fluorocarbon topcoat, which has many advantages such as strong adhesion, good corrosion resistance and anti-aging performance, but this kind of fluorocarbon topcoat is expensive and expensive, and cannot meet the requirements The market demands high gloss. There are also some paints used for spraying on metal surfaces in the prior art, but the effect of spraying is not ideal, and there are defects such as poor appearance quality, easy scratches, easy wear damage, dull luster, and poor outdoor weather resistance, which affects the metal plate. Appearance quali...
