Rust removal and prevention agent and preparation method thereof

Abstract

The invention discloses a rust removal and prevention agent and a preparation method thereof, and belongs to the field of rust prevention agents. After the rust removal and prevention agent is brushed or soaked on the surface of a metal product, rust can be removed, a passivation protective film can be formed on the surface of the metal product, metal is prevented from rusting again, in the preparation process, an anti-oxidation capsule is adopted to prevent aluminum powder and copper powder from being oxidized before being put into use, the purity of raw material components is effectively improved, the anti-oxidation capsule enables two anti-oxidation coating shells to be opened through the dissolution effect of phosphoric acid, the aluminum powder and the copper powder inside the anti-oxidation capsule are released into the phosphoric acid to directly participate in the reaction, the two anti-oxidation coating shells are connected through an elastic series rope so that the two anti-oxidation coating shells can be mutually pulled and entangled under stirring, the raw material mixing and stirring effect is effectively improved, meanwhile, nitrogen is sprayed out from a gas outlet pipe under the dissolution action of water in a solution, the motion amplitude of the anti-oxidation coating shells is increased through the counter-acting force during gas spraying, and the mixing and stirring effect is further improved.

Description

technical field [0001] The invention relates to the field of antirust agents, in particular to a rust removing and antirust agent and a preparation method thereof. Background technique [0002] Metal processing parts are prone to rust during production, processing and transportation, which requires the use of anti-rust oil to form a thin film on the metal surface to prevent metal corrosion. The so-called rust is a mixture of oxides and hydroxides formed on the metal surface due to the action of oxygen and water. Iron rust is red, copper rust is green, and the rust of aluminum and zinc is called white rust. It is difficult for machinery not to come into contact with oxygen, moisture or other corrosive media in the air during operation and storage. These substances will undergo electrochemical corrosion and rust on the metal surface. To prevent corrosion, the above substances must be prevented from contacting the metal. [0003] Anti-rust agent is a super-efficient synthetic ...

AI Technical Summary

Problems solved by technology

[0004] Metal products will normally rust during the production process or the finished product storage process. In order to prevent the surface from rusting and cause corrosion to the metal interior, the metal surface must be treated with anti-rust treatment. The current existing technology is to apply anti-rust oil. A protective oil film is formed on the metal surface to block the corrosion of the metal by water vapor in the air and achieve the purpose of rust prevention. However, the existing anti-rust oil cannot remove the rust that has occurred before, resulting in insufficient passivation film formation. Dense, thus unable to play a long-term anti-rust effect
