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.

Embodiment 1

[0021] A preparation method of long-acting metal anti-corrosion paint is as follows: first break 25 kg of petroleum asphalt into small pieces, put it into a cooking pot, start the mixer when the temperature is gradually raised to 180 ° C, and continue to heat up to 220 ° C until the surface is free of bubbles stop heating. Let it cool naturally to 150°C, open the bottom valve and enter the filter, remove impurities and flow into the mixing pot. Before entering the mixing pot, pump 35 kg of 200# gasoline into the pot, let the hot petroleum asphalt flow in slowly, and start at the same time Mixer, after the petroleum asphalt is added, stir for 40 minutes to produce oil-free anti-corrosion paint; pump oil-free anti-corrosion paint into the preparation pot, add 10 kg of clear oil and stir for 40 minutes, then enter the filter to filter out impurities and discharge as oil-free anti-corrosion paint Oil anti-corrosion paint: pump the oil anti-corrosion paint into the preparation pot,...

Embodiment 2

[0023] A long-term metal anti-corrosion paint includes: 35 kg of petroleum asphalt, 30 kg of 200# gasoline, 10 kg of clear oil, and 30 kg of iron oxide red powder. Its preparation method is identical with embodiment 1.

Embodiment 3

[0025] A long-term metal anti-corrosion paint includes: 30 kg of petroleum asphalt, 45 kg of 200# gasoline, 15 kg of clear oil, and 25 kg of aluminum silver paste. Its preparation method is identical with embodiment 1.

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...
