Gas-phase anti-corrosion paint

Abstract

The invention relates to a gas phase antirust coating, the components of the combination account according to parts by weight, and the scope is as follows: 8 to 25 parts of acrylate modified alkyd resin, 5 to 20 parts of 2402 phenolic resin, 0 to 15 parts of petroleum sulfonate barium, 0 to 25 parts of oxidized malthenes magnesium soap, 0 to 5 parts of dodecatylene base succinic acid imidazoline, 0 to 6 parts of sebacic acid morpholine, 0 to 6 parts of octanoic acid two cyclohexylamines, 0 to 6 parts of octanoic acid tributyl amine, 0 to 6 parts of capric acid tributyl amine, 0 to 15 parts of benzoic acid monoethanolamine, 0.1 to 1.0 part of drier, 0 to 5 parts of thixotropic agent, 1 to 5 parts of dibutyl phthalate, 0 to 5 parts of black paste, and the rest of xylene / 200 model solvent (1:1). The gas phase antirust coating of the invention has the advantages of fast table-drying speed, long antirust time, high rigidity, high brightness, good temperature resistance, etc., and can satisfy the requirements of the automatic pipeline production and long time open storage antirust need of oil steel pipes and other large pipes or profiles.

Description

technical field [0001] The invention belongs to the coating field of fine chemical industry, especially a novel anticorrosion coating in metal anticorrosion technology. Background technique [0002] Corrosion of metal is a phenomenon in which metal is destroyed by chemical or electrochemical action of environmental medium. The corrosion of metals spreads all over the national economy and brings huge losses to the national economy. In developed countries, corroded and rusted steel accounts for about 20% of the output every year, and about 30% of the equipment is scrapped due to corrosion. In China, the economic loss caused by metal corrosion is as high as 30 billion yuan per year, accounting for 4% of the gross national product. [0003] For a long time, people have used a variety of techniques to protect metals from corrosion. Among them, coating anti-rust coatings on metal surfaces is one of the most effective and commonly used methods for metal equipment anti-corrosion....
