Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an environment-friendly long-acting metal antirust agent, which solves the above-mentioned background technology. At present, the metal antirust agents on the market often add formaldehyde, benzene, heavy metals and other harmful substances to their components. It is not environmentally friendly, has potential safety hazards, and is easy to pollute the environment. Moreover, the existing metal antirust agents have weak adhesion ability, and it is difficult to have long-term antirust performance and strong oil film adhesion, which is not easy to meet various harsh conditions. The problem of using the environment

Abstract

The invention discloses an environment-friendly long-acting metal antirust agent, and relates to the technical field of urolithin, in particular to an environment-friendly long-acting metal antirust agent. The environment-friendly long-acting metal antirust agent is prepared from the components in percentage by weight: 15-25% of sulfuric acid, 20-35% of citric acid, 3-10% of ethylene glycol, 1-3%of ethylenediamine tetraacetic acid, 0.1-0.5% of polyvinylpyrrolidone and the balance of water. According to the environment-friendly long-acting metal antirust agent, the sulfuric acid is an inorganic strong acid, has good dispersity, can be completely ionized in a solution, and is beneficial to improving the conductivity, the dispersing capacity and the anode current efficiency of a polishing solution, so that the surface of stainless steel is polished uniformly; and the citric acid is low in acidity and large in viscosity, can achieve a dissolving effect and form a passivation film on the surface of the stainless steel in the polishing process, and prevents over-corrosion of the stainless steel; and the ethylene glycol is adsorbed on the surface of an anode, is beneficial to promoting formation of a diffusion layer, can form a thin film on the surface of the stainless steel together with the citric acid, prevents over-corrosion of the stainless steel, and makes the surface of the polished stainless steel be bright and fine.

Description

Technical field[0001]The invention relates to the technical field of metal surface treatment, in particular to an environmentally friendly long-acting metal rust inhibitor.Background technique[0002]The corrosion of metal parts refers to the damage or deterioration caused by chemical or electrochemical interaction with the surrounding environment. When the part is exposed to moist air, due to its surface adsorption of water in the atmosphere, a very thin moisture layer-water film will be formed on the surface of the part. When this water film reaches a certain thickness (20-30 pieces) Molecular), it will form electrochemical corrosion. This kind of electrochemical process will be aggravated with the increase of temperature and the dissolved CO2 and SO2 in the water. In this way, the iron atoms on the surface of the part will continue to dissolve, forming a film that is dissolved in the water. Fe(OH)2, because Fe(OH)2 is unstable in the water film, it further interacts with the oxygen...
