Metal preservative

Abstract

The invention belongs to the technical field of metal rust prevention, and particularly relates to a metal preservative. The preservative comprises silicone oil, glycerol, polyamide, iron powder, sodium pyrophosphate, acetic acid, oil-soluble phenolic resin, aluminum sulfate, citric acid, zinc dialkyl dithiophosphate, deionized water, paraffin, peppermint oil and magnetic powder. According to theinvention, the iron powder, the paraffin and the peppermint oil are added so that a layer of paraffin film can be formed on a handrail; after being used for a long time, the reduction degree of the metal preservative can be judged by observing the thickness of the paraffin film; the metal preservative is smeared in time when the paraffin film is thin, so that the probability that the handrail is corroded is reduced; meanwhile, the added iron powder can enter the marine organisms along with the paraffin, so that the weight of the marine organisms is increased, the moving resistance of the marine organisms is increased, the moving enthusiasm of the marine organisms is further reduced, and the marine organisms are prevented from corroding a large amount of paraffin.

Description

technical field [0001] The invention belongs to the technical field of metal rust prevention, in particular to a metal anticorrosion agent. Background technique [0002] Metal rusting is the most common form of corrosion. During corrosion, a chemical or electrochemical heterogeneous reaction occurs at the interface of the metal, turning the metal into an oxidized (ion) state. This will significantly reduce the mechanical properties of metal materials such as strength, plasticity, and toughness, destroy the geometry of metal components, increase wear between parts, deteriorate electrical and optical physical properties, shorten the service life of equipment, and even cause disasters such as fire and explosion. sex accident. According to statistics, the annual global economic loss due to steel corrosion accounts for about 4% of global GDP. Therefore, how to effectively prevent corrosion has always been a hot and difficult point in the industry's research. At present, people...

Problems solved by technology

[0003] There are also some technical solutions about metal preservatives in the prior art. For example, the Chinese patent application number 201711111973.2 discloses a metal preservative and its application. The raw materials used in it are non-toxic and will not harm the body during the production process. cause damage, using the present invention to carry out anti-corrosion treatment on metal will form a layer of protective film on the metal surface, which can not only enhance the anti-corrosion performance of metal, prolong the life of metal materials and devices, but also has no pollution to the environment, can be degraded, and has low cost. Especially for the incision of galvanized steel sheet; but when it is used on board, the fence at the deck of a small ship will have marine organisms attached to the railing due to the baptism of wind and waves, causing corrosion of the railing. In view of this, the present invention provides A metal preservative, which can reduce the survival rate of marine organisms and improve the safety of use
