Environment-friendly waterproof corrosion-resistant marine coating

Abstract

The invention discloses an environment-friendly waterproof corrosion-resistant marine coating. The environment-friendly waterproof corrosion-resistant marine coating consists of the following materials in parts by weight: 30 to 40 parts of polyvinyl acetal-modified phenolic resin, 10 to 15 parts of poly(ethyl acrylate) emulsion, 20 to 30 parts of organic silicon-modified polyester resin, 10 to 15 parts of isophthalic unsaturated polyester resin, 3 to 13 parts of lead chromate, 3 to 12 parts of hydroxypropyl methylcellulose, 2 to 6 parts of sodium carboxymethylcellulose, 1 to 5 parts of hydroquinone, 5 to 15 parts of aluminium nanopowder, 10 to 15 parts of modified mica, 10 to 15 parts of aluminium hydroxide, 15 to 20 parts of nano calcium oxide, 5 to 10 parts of zinc oxide, 2 to 4 parts of chromium phosphate, 1 to 3 parts of barium phosphate, 5 to 10 parts of calcium phosphate, 1 to 3 parts of iron oxide red and 2 to 5 parts of phthalocyanine blue. The waterproofness of the environment-friendly waterproof corrosion-resistant marine coating is good, the corrosion resistance of the environment-friendly waterproof corrosion-resistant marine coating is excellent, and moreover, the environment-friendly waterproof corrosion-resistant marine coating does not pollute the environment.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an environment-friendly waterproof and anti-corrosion coating for ships. Background technique [0002] 4 / 5 of the earth's surface is covered by the ocean, which plays a huge role in the economic and social development of the eastern coastal areas of my country. Rust has always been a global problem that plagues people. Corrosion can not only reduce the strength of the ship's steel structure and shorten the life of the ship, but also increase the navigation resistance, reduce the speed of the ship, and affect the safety of the ship. It is economical to paint the ship. The advantages of effectiveness and ease of operation have developed the fastest in recent years and are the most widely used. However, traditional anti-corrosion coatings contain heavy metal compounds, which are easy to pollute the environment and cause harm to the human body. They have been unable to meet the new st...

[0002] 4 / 5 of the earth's surface is covered by the ocean, which plays a huge role in the economic and social development of the eastern coastal areas of my country. Rust has always been a global problem that plagues people. Corrosion can not only reduce the strength of the ship's steel structure and shorten the life of the ship, but also increase the navigation resistance, reduce the speed of the ship, and affect the safety of the ship. It is economical to paint the ship. The advantages of effectiveness and ease of operation have developed the fastest in recent years and are the most widely used. However, traditional anti-corrosion coatings contain heavy metal compounds, which are easy to pollute the environment and cause harm to the human body. They have been unable to meet the new standards and requirements of the marine coating market. Require
