Problems solved by technology

However, the patent does not provide specific products and relevant experimental data to prove it, and the formula provided in the patent is relatively vague and covers a large number of situations. Coatings with the above effects
At the same time, it does not give how to further improve the coatings resistant to harsh environments
In addition, even if it can achieve the claimed effect, the paint still has problems that need to be improved. First, the formula is too complicated; Grinding, inconvenient production, high cost, poor product controllability, these factors will limit the popularization and application of this coating

Embodiment 1

[0045] This example provides an anti-corrosion coating and a preparation method thereof. The raw material formula of the anti-corrosion coating is shown in Table 1, wherein the solvent is methyl isobutyl ketone; the dispersant is polycarboxylate dispersant BYK163; the water remover is oxazolidine and calcium chloride in a weight ratio of 1:0.2 . Pigments and fillers are composed of titanium dioxide, barium metaborate, zinc aluminum alloy powder, and silicon dioxide in a ratio of 1:0.3:1.5:0.8.

[0046] The preparation method of anticorrosion coating is as follows:

[0047] (1), according to the formula ratio, the polyurethane modified ethylene propylene hexadiene copolymer and isopropyl butyrate are put into the first mixer for stirring and mixing, and the stirring time is 30 minutes;

[0048] (2), adding the mixture obtained in step (1) into the first reaction kettle, controlling the temperature at 300° C., and reacting for 3 hours to obtain a spherical network polymer resi...

Embodiment 2

[0054] This example provides an anti-corrosion coating and a preparation method thereof. The raw material formula of anti-corrosion coating is shown in Table 1, in which, the solvent is methyl isobutyl ketone; the dispersant is polycarboxylate dispersant BYK163; the dewatering agent is composed of oxazolidine and calcium chloride in a weight ratio of 1:5 . Pigments and fillers are composed of titanium dioxide, barium metaborate, zinc aluminum alloy powder, and silicon dioxide in a ratio of 1:0.1:0.8:1.

[0055] The preparation method of this example with wet band rust anticorrosion primer material is basically the same as embodiment 1.

Embodiment 3

[0057] This example provides an anti-corrosion coating and a preparation method thereof. The raw material formula of the anti-corrosion coating is shown in Table 1. Among them, the solvent is methyl butanone; the dispersant is polycarboxylate dispersant BYK9076; the water remover is oxazolidine in a weight ratio of 1:2. Pigments and fillers are composed of red iron oxide, barium metaborate, and silicon dioxide in a ratio of 1:0.1:1.

[0058] The preparation method of this example anticorrosion coating is as follows:

[0059] (1), according to the formula ratio, the polyurethane modified ethylene propylene hexadiene copolymer and isopropyl butyrate are put into the first mixer for stirring and mixing, and the stirring time is 30 minutes;

[0060] (2), adding the mixture obtained in step (1) into the first reaction kettle, controlling the temperature at 250° C., and reacting for 4 hours to obtain a spherical network polymer resin;

[0061] (3), put other raw materials in the f...

Abstract

An anti-corrosion coating and a preparation method thereof belong to the technical field of anti-corrosion coatings. The present invention takes a specific spherical network polymer resin as the resin component of the material, combines with aminopropyl-containing siloxane, and mixes with appropriate solvents, conventional dispersants, defoamers, modified graphene, pigments, etc. It has excellent performance, is suitable for various rusty working conditions, can be painted under different thicknesses of rust layers, different composition rust layers, and different humidity conditions, and has a high fault tolerance rate. The coating of the invention can make on-site maintenance simple and feasible, and compared with the prior art, can solve the problem of wetness and effectively improve the anti-corrosion performance.

Description

technical field [0001] The invention relates to an anti-corrosion coating, in particular to an anti-corrosion coating material suitable for environments with harsh conditions and a preparation method thereof. Background technique [0002] Under the premise that various equipment such as ports, docks, highways, bridges, industrial plants, chemical parks, transmission pipelines, and underground pipe galleries cannot be moved, anti-corrosion maintenance is very difficult and the project quality is particularly poor. This is because, for anti-corrosion engineering maintenance, if the anti-corrosion coating is to play a role, strict surface treatment is required, that is, the rust on the substrate must be completely removed before painting, and it must be painted in a dry environment, otherwise There will be a problem of rapid rusting. Corrosion growth will destroy the paint film and render the paint film ineffective. [0003] Painting in the market now requires factory sandbla...
