Embodiment 1

[0040] An anti-corrosion coating for wet coating with rust and band, according to parts by weight, has the following components, specifically as shown in Table 1 to Table 6:

[0041] Component A:

[0042] Resin: bisphenol A epoxy resin E20;

[0043] Pigments and fillers: titanium dioxide, zinc oxide, zinc phosphate, calcium phosphate, aluminum tripolyphosphate, barium sulfate;

[0044] Rust conversion agent: phosphoric acid, potassium ferrocyanide, tannic acid, butanol;

[0045] Mixed solvent: methyl isobutyl ketone, xylene, butanol;

[0046] Auxiliaries: anti-settling agent, leveling agent, dispersant;

[0047] Component B:

[0048] Cardanol modified phenalkamine;

[0049] Mixed solvents: methyl isobutyl ketone, xylene, butanol.

[0050] According to the ratio of parts by weight, component A: component B = 90 ~ 100: 1 ~ 1.2 (mixed before use);

[0051] In component A, in terms of parts by weight, resin: pigment and filler: rust converting agent: mixed solvent = 25-28: ...

Abstract

The invention discloses an anticorrosive paint coated under rusted and moist conditions and particularly discloses a bicomponent epoxy anticorrosive paint which can be coated on rusted and moist steel surfaces and can play a protective role. The anticorrosive paint comprises a component A and a component B, wherein the component A is composed of the following components in parts by weight: 25-28 parts of epoxy resin, 33-36 parts of pigment and filler, 3.5-5 parts of rust transforming agent, 30-35 parts of mixed solvent and 0.5-1.5 parts of auxiliaries; and the component B is composed of the following components in parts by weight: 75-80 parts of modified mannich amide hardener and 20-25 parts of mixed solvent. The weight ratio of the component A to the component B is (90-100): (1-1.2), and the component A and the component B are mixed before being used.

Description

technical field [0001] The invention relates to a coating, in particular to an anti-corrosion coating for wet coating with rust and belt. Background technique [0002] Corrosion is the enemy of human beings. The loss of steel caused by silver corrosion accounts for as much as 4% of the national economic output, which is six times the sum of losses caused by all natural disasters. [0003] The most economical and effective way to deal with corrosion is to use anti-corrosion coatings. The amount of corrosion coatings is large, and it is the second largest variety in the coatings industry. The total amount of anti-corrosion coatings used for anti-corrosion in my country exceeds one million tons every year. [0004] However, before the anti-corrosion coating is applied to metal surfaces such as steel, the rust on the metal surface must be removed, and in some environments, the moisture on the steel surface must be removed. Such as the coating of marine structures, its surface ...
