Water-soluble antirust agent and preparation method thereof

Abstract

The invention relates to a water-soluble antirust agent and a preparation method thereof. The water-soluble antirust agent comprises 14-16 parts of hydrofluoric acid, 3-7 parts of nitrate acid-hydrofluoric acid, 4-10 parts of etidronic acid, 8-13 parts of sodium phytate, 12-17 parts of isopropanol, 7-9 parts of metal powder, 16-25 parts of potatoes, 5-8 parts of polyvinyl alcohol, 6-9 parts of silicon dioxide, 13-15 parts of epoxy ester, 8-11 parts of a defoaming agent, 6-8 parts of o-toluidine and 2-3 parts of bactericide. By means of the water-soluble antirust agent, a connecting piece which becomes difficult to unscrew due to rust corrosion can be effectively released, and the connecting piece can be detached easily. The water-soluble antirust agent contains special additives and can permeate rust, corrosives, oil stains, mud and the like so that the connecting piece can be released slowly and removed easily, and dirt such as incrustation and dust adhering to the surface of metal can be effectively removed; and besides, an antirust oil film is reserved on the surface of metal or other materials, so that moisture and water are effectively isolated and the service life of the connecting piece is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of industrial organic cleaning agents, in particular to a water-soluble antirust agent and a preparation method thereof. Background technique [0002] Metal is easily oxidized by oxygen when exposed to the air, and a layer of rust will form on the metal surface after oxidation. Therefore, when processing metal parts, it is necessary to remove the rust on the metal surface in order to use the metal normally, but rusty metal is not only It has a certain impact on the metal surface, its mechanical properties will also be affected to a certain extent, and it will have a certain impact on its product quality. The rusted product has a short life and cannot be used normally. The corroded metal is polluted environment, and waste a lot of resources and energy consumption. The rusted metal cannot be used any longer, which will cause a certain waste of resources. In order to effectively improve the performance of the ...

[0002] Metal is easily oxidized by oxygen when exposed to the air, and a layer of rust will form on the metal surface after oxidation. Therefore, when processing metal parts, it is necessary to remove the rust on the metal surface in order to use the metal normally, but rusty metal is not only It has a certain impact on the metal surface, its mechanical properties will also be affected to a certain extent, and it will have a certain impact on its product quality. The rusted product has a short life and cannot be used normally. The corroded metal is polluted environment, and waste a lot of resources and energy consumption

The rusted metal cannot be used any longer, which will cause a certain waste of resources. In order to effectively improve the performance of the metal, it is necessary to carry out certain treatments on the metal surface to effectively increase the antirust performance of the metal surface

Existing derusting methods mainly include physical methods, chemical methods and electrochemical methods. Existing enterprises use antirust agents on metal surfaces to prevent rust on metals. Although they have a certain antirust effect, the effect is not good and cannot Carry out long-term anti-rust to metal, and the anti-rust preservative used now is inconvenient to clean, and the anti-oxidation, anti-corrosion, acid resistance and moisture-proof functions of the existing anti-rust agent are not strong enough, which brings trouble to actual use. Therefore, The development of a water-soluble rust inhibitor has always been a research problem in the industry
