Abstract

The present invention discloses a phosphating anti-rust oil, which comprises the following raw materials by weight: 2-4 parts of phosphotungstic acid, 1-2 parts of hexahydrophthalic anhydride, 0.4-1 part of N-sodium lauroylsarcosinate, 0.5-1 part of sp-80, 2-3 parts of dioctyl azelate, 1-2 parts of 2-mercaptobenzimidazole, 1-2 parts of potassium sodium silicate, 1-2 parts of ammonium polyphosphate, 2-3 parts of methyl ester nylon acid, 70-80 parts of 30# machine oil, 4-6 parts of an anti-rust agent t702, 0.7-2 parts of 2-naphthol, 3-4 parts of potassium dihydrogen phosphate, and 4-5 parts of film forming machine oil. According to the present invention, the added film forming machine oil pentaerythrite oleate with characteristics of excellent lubricity and good surface film forming property and the dodecyl alcohol ester are subjected to co-mixing modification so as to significantly improve the film forming effect of the finished product and reduce the film forming temperature, and the added rare earth lanthanum ions and the OH<-1> produced during the oxygen uptake etching process occurring on the metal substrate surface can produce the insoluble complex so as to slow down the etching electrode reaction and provide the good slow-release effect.

Description

technical field [0001] The invention mainly relates to the field of lubricating oil, in particular to a phosphating antirust oil. 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 anti-rust oil, prolong the ...
