Special anti-rust oil for iron powder stamping part

Abstract

The invention discloses special anti-rust oil for an iron powder stamping part. The special anti-rust is prepared from the following raw materials in parts by weight: 0.4-1 part of potassium fluotitanate, 1-2 parts of calcium lactate, 4-7 parts of acetylated lanolin, 0.5-1 part of p-tertiary-butyl phenol, 1-2 parts of trisodium phosphate, 1-2 parts of dibutyl maleate, 2-3 parts of polyvinylidene fluoride, 2-3 parts of triethyl acetyl citrate, 2-3 parts of origanum oil, 60-70 parts of 150sn base oil, 0.5-1 part of triethanolamine, 5-7 parts of neutral dinonyl-naphthalenesulfonic acid barium salt, 1-2 parts of sebacic acid, 0.3-0.6 part of sp-80 and 5-6 parts of anti-stripping machine oil. The added film-forming machine oil, namely pentaerythritol oleate, has the excellent lubricating property and good film-forming property; through blending modification with n-dodecanol ester, the film-forming effect of the finished product can be obviously improved; the film-forming temperature is reduced; and the added rare-earth lanthanum ion can generate an insoluble complex together with OH<-1> generated in the oxygen absorption corrosion process on the surface of a metal base material, so that electrode reaction of corrosion is retarded; and a good slow-release effect is achieved.

Description

technical field [0001] The invention mainly relates to the field of lubricating oil, in particular to a special antirust oil for iron powder stamping parts. 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 o...
