Abstract

The invention discloses an extreme pressure antiwear and antirust oil, which is composed of the following raw materials by weight part: 1-2 of nitrilotriacetic acid trisodium salt, 1-2 of star anise oil, 0.6-1 of sodium nitrite, 2-3 of phthalic acid ester, 1-2 of linalool, 1-2 of polyglycerol fatty acid ester, 0.4-1 of potassium citrate, 0.4-1 of phthalic anhydride, 0.6-1 of lithium naphthenate, 0.4-1 of castor oil polyoxyethylene ether, 4-6 of petroleum sodium sulfonate, 60-70 of n68# machine oil, 2-4 of T321 isobutenyl sulfide, and 4-6 of anti-stripping machine oil. The film-forming machine oil pentaerythritol oleate added in the invention has excellent lubricity and good surface film-forming property, and blending modification with alcohol ester-12 can obviously improve the film-forming effect of the finished product and lower the film-forming temperature. The added rare earth lanthanum ion and the OH- generated in an oxygen absorption corrosion process on a metal substrate surface can generate an insoluble complex to slow down corrosive electrode reaction so as to play a good slow-release role.

Description

technical field [0001] The invention mainly relates to the field of lubricating oil, in particular to an extreme pressure anti-wear and anti-rust 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-r...
