Abstract

The invention discloses hard film anti-rusting oil for a railway wheel hub. The hard film anti-rusting oil is prepared from the following raw materials in parts by weight: 0.5-1 part of geranyl butyrate, 2-3 parts of propylene glycol monomethyl ether, 3-5 parts of wood creosote oil, 4-6 parts of dodecencylsuccinic acid, 2-3 parts of sucrose acetate isobutyrate, 1-2 parts of isopropyl palmitate, 70-80 parts of 120# solvent oil, 0.6-1 part of dialkyl p-diphenol, 1-2 parts of sodium carboxymethyl cellulose, 0.4-1 part of ammonium trimolybdate, 0.6-1 part of an antioxidant DLTP, 3-5 parts of sodium myrastate, 3-4 parts of rosin, and 5-6 parts of anti-stripping mechanical oil. The added film-forming mechanical oil and pentaerythritol oleate have excellent lubricating property and good surface film-forming property, and are mixed and modified with 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, so that the film-forming effect of a finished product can be obviously improved and the film-forming temperature is lowered; the added rear-earth lanthanum ion can react with OH<-> produced in an oxygen absorption corrosion process on a metal base material surface to produce an insoluble complex, so that the corrosion electrode reaction is retarded to achieve a good slow release effect.

Description

technical field [0001] The invention mainly relates to the field of lubricating oil, in particular to a dura-film antirust oil used for train wheel hubs. Background technique [0002] Corrosion is one of the main forms of damage to fasteners, and it will cause great losses to automobiles, motorcycles and various vehicles and machinery. According to statistics, the annual direct economic loss caused by metal corrosion accounts for about 2-4% of the total output value of the national economy. Under the influence of substances such as carbides, under certain conditions of temperature, humidity and time extension, physical and chemical changes will occur and rust will occur. The corrosion of metal will cause the loss of metal and the decline and loss of the function of metal parts. Metal corrosion is caused by the oxidation reaction of metal in contact with moist air or electrolyte solution. Therefore, it is necessary to continuously improve the anti-rust effect of ant...
