Lasting metal corrosion-resistant paint

Abstract

The lasting metal corrosion preventing paint is prepared with petroleum asphalt, organic solvent, boiled oil, and pigment. The preparation process includes crushing and boiling asphalt while stirring until no bubble, cooling naturally, filtering at 150 deg.c; mixing hot asphalt with organic solvent in a mixer under stirring; mixing with boiled oil in the second mixer, filtering; mixing with pigment in the second mixer via stirring, and final filtering. The lasting metal corrosion preventing paint has wide application range, long anticorrosive period, low temperature tolerance, sun resistance, etc.

Description

technical field [0001] The invention relates to an anticorrosion coating, in particular to a long-acting metal anticorrosion coating. technical background [0002] Anti-corrosion coatings are an important means of anti-corrosion, and anti-corrosion coatings are developing rapidly. For more than 50 years, the varieties have developed from red lead, alkyd, epoxy coal tar pitch, epoxy resin to chlorosulfonated polyethylene, epoxy polyamide, epoxy mica, chlorinated rubber, polyurethane, organic fluorine There are more than a thousand kinds, but the anticorrosion life of anticorrosion coatings is still not very good. In order to achieve the purpose of prolonging the anti-corrosion period, the selected raw materials are more expensive, the process and technology are more difficult, the product price is naturally higher and the construction is more and more complicated, but the anti-corrosion period does not exceed ten years. Although a few asphalt paints have better anti-cor...

AI Technical Summary

Problems solved by technology

In order to achieve the purpose of prolonging the anti-corrosion period, the selected raw materials are more expensive, the process and technology are more difficult, the product price is naturally getting higher and higher, and the construction is becoming more and more complicated, but the anti-corrosion period does not exceed ten years.

Although a small number of asphalt paints have better anti-corrosion properties and longer anti-corrosion years, they have poor mechanical properties and cannot be applied to the surface of objects exposed to sunlight. The main reason is to focus on the selection of petroleum asphalt with a high softening point.
