Anti-oxidation paint for steel materials of ships and preparation method of anti-oxidation paint

Abstract

The invention discloses an anti-oxidation paint for steel materials of ships and a preparation method of the anti-oxidation paint. The anti-oxidation paint comprises the following raw materials by weight: 20 to 30 parts of conduction oil, 20 to 30 parts of n-butanol, 8 to 12 parts of polystyrene, 14 to 18 parts of ethylene glycol monomethyl ether, 0.8 to 1.2 parts of calcium stearate, 0.6 to 0.8 part of lanois magnesium soap, 10 to 15 parts of polyacrylonitrile fiber, 2 to 3 parts of an anti-oxidant, 3 to 5 parts of 1-butyl-3-methylimidazolium chloride, 2 to 3 parts of an organic thickening agent, 1.2 to 1.4 parts of stratiform magnesium silicate, and 4 to 6 parts of a filling agent. According to the preparation method, contact among the raw materials can be more sufficient, so that the dispersity and the compatibility are better, and coating slurry can be effectively prevented from layering; as the anti-oxidant can improve the corrosion resistance of the anti-oxidation paint obviously, and the binding force between the paint and a steel material base body is high, even when an oil layer is swept, chemical complex between corrosion inhibitor molecules and the base body cannot be removed, so that the rustproof performance is better; the anti-corrosion time of a steel material treated with the paint can reach 3 years or longer when the steel material is used normally; the anti-oxidation paint can be used widely.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an anti-oxidation coating for ship steel and a preparation method thereof. Background technique [0002] Steel is widely used in mechanical equipment, building decoration and other fields. The problems of corrosion, static electricity and electromagnetic interference on the surface of steel have always been urgent problems to be solved. Especially steel is widely used in outdoor environments because of its good mechanical strength. , humidity and ultraviolet rays will cause corrosion on the surface of the steel. At the same time, since the steel is a conductor, the static electricity caused has become a safety hazard during use. How to prolong the service life of steel and improve its performance is a very important issue. The steel surface is a special steel that can work repeatedly under dynamic load conditions. During use, the outer layer of the component become...

The existing surface treatment of the steel surface is mainly through the galvanizing process. This method is costly and complicated, and the zinc coating is prone to corresponding surface defects due to the imperfect galvanizing process, resulting in oxidation, making the surface of the steel rough. , the brittleness increases, and microcracks are easily generated at the junction of the galvanized layer and the surface of the steel due to the activities of various parts
