Anti-rust paint for coating surfaces of ships

Abstract

The invention discloses an anti-rust paint for coating the surfaces of ships. The anti-rust paint comprises the following components in parts by weight: 25-35 parts of a styrene-acrylic emulsion, 10-30 parts of inositol hexaphosphate, 2-5 parts of copper powder, 1-3 parts of quartz powder, 2-3 parts of aluminum dihydrogen tripolyphosphate, 0.2-0.5 part of silicon dioxide, 0.05-1 part of calcium oxalate and 100 parts of water. Experimental analysis shows that the anti-rust paint for coating the surfaces of ships can work 20 years under the condition of high salinity, has a better color-fixing effect than the general anti-rust paint, is free from dropping after being subject to long-term water immersion, has strong adhesiveness, can better protect the ships and increase the use value of the ships and has a very broad commercial prospect.

Description

technical field [0001] The invention relates to an antirust paint. Background technique [0002] Metal rusting is the most common and costly form of corrosion. Antirust work has always been one of the major scientific research topics at home and abroad. People have studied various measures to prevent and inhibit metal corrosion, and antirust with paint is an effective method. For anti-rust, since steel accounts for 95% of metal usage, and 70% of steel is used in an atmosphere that is prone to rust, preventing atmospheric corrosion of steel is the main task of anti-rust paint. The main components of antirust paint are antirust pigments and film-forming substances. It is usually named after the name of the antirust pigment, such as: red lead antirust paint, iron red antirust paint, etc. If they are distinguished by their anti-rust mechanism, they can be roughly classified into four types: physical anti-rust paint, chemical anti-rust paint, electrochemical anti-rust paint an...

Problems solved by technology

[0003] The ship has been immersed in seawater for a long time and is strongly corroded by the salt in the seawater. The general anti-rust paint cannot meet the long-term salt corrosion resistance requirements, and the color will become dull and the paint skin will be damaged in a short time.
