What is the difference between anti-rust paint and paint? What is the future development of anti-rust paint?

Anti-rust paint is a kind of substance that plays the role of anti-rust, prevents metal corrosion and improves the protective effect of paint film on metal surface. The role of anti-rust paint can be divided into two categories: physical anti-rust and chemical anti-rust, of which chemical anti-rust paint can be divided into corrosion inhibition and electrochemical action type two. The substances that play the role of rust prevention mainly include red pink powder, iron red powder, composite iron titanium powder, aluminum tripolyphosphate zinc powder and so on. At present, anti-rust paint is mainly used in anti-corrosion coatings, and the cost of anti-corrosion coatings accounts for 6%-8.5%.

Antirust paint is a kind of paint that can protect metal surfaces from chemical or electrochemical corrosion of atmosphere, seawater, etc. Physical and chemical anti-rust paint, such as iron red, aluminum powder, graphite anti-rust paint, red lead, zinc yellow anti-rust paint and so on.

Paint is a chemical mixture coating that firmly covers the surface of objects, protects, decorates, marks and other special purposes, and forms a solid film that adheres firmly to the surface of objects and has a certain strength and continuity.

1. Different functions:

Anti-rust paint has the properties of anti-corrosion and anti-rust, the film is tough, excellent performance, and the hardness is higher than that of ordinary paint. Ordinary paint has no anti-rust function, because the ordinary paint film material is alkyd resin, through oxidation and drying, poor hardness, adhesion grade gap.

2. Different service life:

Anti-rust paint can be used for 5-8 years in the case of matching. Ordinary paint is usually used outdoors for about 3 years. After two or three years, it is easy to fall off, fade and powder.

3. Different varieties:

Anti-rust paint: phenolic anti-rust paint, alkyd anti-rust paint (iron red, gray, red lead), chlorinated rubber anti-rust paint, epoxy anti-rust paint (zinc phosphate anti-rust paint, red lead anti-rust paint, zinc rich anti-rust paint, iron red anti-rust paint), etc

Paint: Rich varieties of paint, anti-rust paint is also a kind of paint, in addition to the paint also includes wood paint, floor paint, exterior wall paint, stone paint, multi-color paint, aluminum alloy paint, fireproof paint, latex paint and so on.
