Embodiment 1

[0022] A gas-phase slow-release antirust oil is characterized in that it is composed of the following raw materials in parts by weight (kg):

[0023] Dicyclohexylamine Nitrite 4, Hydroxamic Acid 0.2, Lanolin 5, Hydrogenated Castor Oil 5, Hexamethamine 1, Diethanolamide Cocoate 2, Calcium Ricinoleate 2, Dibutyl Phthalate 2, Allyl thiourea 0.5, zinc dialkyldithiophosphate 0.4, 250sn base oil 70, mannitol 2, rust inhibitor T706 4, film-forming machinery oil 5;

[0024] Described film-forming machine oil is made up of the raw material of following weight part:

[0025] Deionized water 60, dodecyl alcohol ester 7, pentaerythritol oleate 2, crosslinking agent TAIC 0.2, triethanolamine oleic acid soap 3, lanthanum nitrate 4, mechanical oil 100, zinc dihydrogen phosphate 10, 28% ammonia water 50, Silane coupling agent KH560 0.2;

[0026] Take 30% of the weight of the above-mentioned triethanolamine oleic acid soap, add it to pentaerythritol oleic acid ester, stir and mix at 70°C for...

Abstract

Disclosed gas-phase slow-release antirust oil is composed of the following raw materials in parts by weight: 2-4 parts of dicyclohexylammonium nitrite, 0.1-0.2 part of hydroxy oximido acid, 3-5 parts of lanolin, 3-5 parts of hydrogenated castor oil, 1-3 parts of urotropine, 1-2 parts of coconut diethanolamide, 1-2 parts of calcium ricinolate, 1-2 parts of dibutyl phthalate, 0.2-0.5 part of allylthiourea, 0.4-1 part of zinc dialkyl dithiophosphate, 60-70 parts of 250sn base oil, 1-2 parts of mannitol, 4-6 parts of antirust agent T706, and 3-5 parts of film-forming machine oil. The added film-forming machine oil pentaerythrityl oleate possesses excellent lubricity and good surface film-forming property, and is capable of obviously improving the film-forming effect of a finished product and reducing film-forming temperature after being blended with 2,2,4-trimethyl-1,3-pentanediolmono(2-methylpropanoate) for modification; and the added rare earth lanthanum ion is capable of reacting with OH<-> generated in an oxygen-absorption corrosion process on a metal base material surface so as to generate an indissoluble complex, helps to alleviate corrosion electrode reaction and gives play to extremely good slow release effect.

Description

technical field [0001] The invention mainly relates to the field of lubricating oil, in particular to a gas-phase slow-release 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, p...
