Anti-corrosion asphalt paint

Abstract

An anticorrosion asphalt paint for metal is prepared from petroleum asphalt (20-40 wt.%), solvent oil (30-50%), xylene (5-10%), rosin oil (5-10%) and green oil (5-15%). Its advantages include high adhesion, high effect on resisting water, moisture, corrosion, high temp and cracking, and easily erasing it by gasoline.

Description

technical field [0001] The invention relates to a metal anti-corrosion asphalt paint with petroleum asphalt as the main film material, especially metal spare parts that need to be stored indoors or in the open air for a long time, and the processed surface needs anti-corrosion maintenance. Background technique [0002] Metal corrosion is not only a huge waste of materials, but also brings huge economic losses. The anti-corrosion of the metal surface generally adopts anti-corrosion paint. Most of our country uses solvent-based anti-rust paint, such as iron red phenolic primer and iron red alkyd primer. In the 1960s, foreign countries began to develop water-soluble resin anti-rust paint. In recent years, water-soluble acrylic acid ester resin anti-rust paint has been developed. Rust paint, water-soluble anti-rust paint is expensive and lacks raw materials. It is not as good as solvent-based anti-rust paint in terms of paint film drying rate, leveling, and hardness. However, du...

[0002] Metal corrosion is not only a huge waste of materials, but also brings huge economic losses. The anti-corrosion of the metal surface generally adopts anti-corrosion paint. Most of our country uses solvent-based anti-rust paint, such as iron red phenolic primer and iron red alkyd primer. In the 1960s, foreign countries began to develop water-soluble resin anti-rust paint. In recent years, water-soluble acrylic acid ester resin anti-rust paint has been developed. Rust paint, water-soluble anti-rust paint is expensive and lacks raw materials. It is not as good as solvent-based anti-rust paint in terms of paint film drying rate, leveling, and hardness. However, due to its poor adhesion, the current solvent-based anti-rust paint takes time It will fall off in pieces after a long time, so the service life is short, especially the surface of the paint layer is easily polluted by dirt and it is difficult to clean
