preparation example Construction

[0034] The preparation of the heavy anticorrosion paint that the embodiment of the present invention provides mainly comprises the following steps:

[0035] Ultrasonic treatment is performed on the montmorillonite, graphite and lithium cobaltate are added after ultrasonication for 40-80 minutes, and the ultrasonication is continued for 50-90 minutes to obtain a composite material after intercalation. Graphite and lithium cobaltate may not be put in at the same time. For example, graphite is put in first and then ultrasonicated for 20-40 minutes, and then lithium cobaltate is put into ultrasonication for 30-50 minutes, so that the graphite layer and lithium cobaltate layer can be placed between the layers of montmorillonite. Alternately formed, so that the paint has better protection ability.

[0036] Polyethylene glycol and epoxy resin can be melt-blended first, and the polyethylene glycol and epoxy resin can be fully mixed to ensure that the epoxy resin is evenly mixed in the...

Embodiment 1

[0047] The present embodiment provides a kind of heavy anticorrosion paint, and its preparation method is as follows:

[0048] Ingredients: 10g of montmorillonite, 5g of graphite, 5g of lithium cobaltate, 50g of additives, 80g of the first component, 100g of the second component and 50g of ceramic microbeads.

[0049] The additive is ethylene-methacrylic acid copolymer; the weight ratio of aromatic diamine and anti-aging additive in the first component is 1.5:2; the second component includes a silane coupling agent with a weight ratio of 1:2:2.4 , polyethylene glycol and epoxy resin.

[0050] When the anti-corrosion coating is used, it is prepared on site, and its preparation and painting process steps are as follows:

[0051] The montmorillonite is subjected to ultrasonic treatment, after 40 minutes of ultrasonication, graphite and lithium cobaltate are added, and the ultrasonication is continued for 50 minutes to obtain a composite material after intercalation. Mix the com...

Embodiment 2

[0053] The present embodiment provides a kind of heavy anticorrosion paint, and its preparation method is as follows:

[0054] Ingredients: 25g of montmorillonite, 15g of graphite, 15g of lithium cobaltate, 12g of sodium pyrophosphate, 10g of additives, 30g of the first component, 50g of the second component and 20g of ceramic microbeads.

[0055] The additive is a silicon-based oxide; the weight ratio of aromatic diamine and anti-aging additive in the first component is 1.5:1; the second component includes a silane coupling agent with a weight ratio of 1:2:1.5-2.3, Polyethylene glycol and epoxy resin.

[0056] When the anti-corrosion coating is used, it is prepared on site, and its preparation and painting process steps are as follows:

[0057] The montmorillonite is subjected to ultrasonic treatment, after 80 minutes of ultrasonication, graphite and lithium cobaltate are added, and the ultrasonication is continued for 90 minutes to obtain a composite material after intercal...

Abstract

The invention provides heavy-duty anticorrosive paint as well as a preparation method and a painting method thereof, relating to the technical field of paint. The heavy-duty anticorrosive paint is prepared from the following raw materials in parts by weight: 10-25 parts of imvite, 5-15 parts of graphite, 5-15 parts of lithium cobalt oxide, 10-50 parts of additives, 30-80 parts of first ingredients, 50-100 parts of second ingredients and 20-50 parts of ceramic microbeads. The graphite and lithium cobalt oxide are both inserted between imvite layers. The additives is prepared from an inorganic additive and / or an organic additive. The first ingredients are prepared from a curing agent and an anti-aging adjuvant in a weight ratio of 1.5: (1 to 2). The second ingredients are prepared from a silane coupling agent, polyethylene glycol and epoxy resin in a weight ratio of 1 to 2 to (1.5-2.5). The imvite subjected to layer insertion can form multiple interlaced protection layers in the paint, various corrosive fluids can be prevented from invading into an inner layer of the paint to reach the surface of a base material to cause corrosion in a severe environment, and the anticorrosive capacity of the paint is improved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a heavy-duty anti-corrosion coating, a preparation method and a painting method thereof. Background technique [0002] Heavy-duty anti-corrosion coatings refer to a class of anti-corrosion coatings that can be applied in relatively harsh corrosive environments and have a longer protection period than conventional anti-corrosion coatings compared with conventional anti-corrosion coatings. However, the anticorrosion performance of heavy-duty anti-corrosion coatings used in heavy-duty anti-corrosion painting is still not satisfactory, and the protection period is relatively short. Contents of the invention [0003] The purpose of the present invention is to provide a heavy-duty anti-corrosion coating, which can carry out long-term anti-corrosion to materials in harsh natural environments, and reduce painting workload and material loss. [0004] Another object of the present inve...
