Abstract

The invention belongs to the technical field of lubricating oil, and particularly relates to a preparation method of wear-resistant anti-corrosion gear oil. The method comprises the following steps: adding titanium sulfate into water and mixing; mixing with a roasted powder, a modified nano-powder, toluene and other assistants; after mixing, adding oil, and stirring at high temperature to obtain the wear-resistant anti-corrosion gear oil. Titanium sulfate is used as a raw material, and is reacted with ammonia water and is calcined at high temperature to generate titanium dioxide ultrafine powder, zinc ions are introduced and are react with sodium sulfide to improve the wear resistance and friction reduction performance of an oil product, and meanwhile, the corrosion resistance of the gearoil is improved by combining the good chemical corrosion resistance of titanium dioxide and zinc sulfide; zinc nitrate hexahydrate and urea are mixed and subjected to a high-temperature water boilingreaction, zinc oxide ultrafine powder has a good rigid structure and is dispersed in the gear oil, the wear resistance and friction reduction performance of the gear oil can be enhanced, meanwhile, electrostatic repulsion can be formed among ultrafine powder particles, the wear resistance and friction reduction performance of the gear oil are improved, and wide application prospects are achieved.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and in particular relates to a preparation method of wear-resistant and anti-corrosion gear oil. Background technique [0002] Gear oil mainly refers to the lubricating oil of transmission and rear axle. There are differences between it and engine oil in the conditions of use, its own composition and performance. Gear oil mainly plays the role of lubricating gears and bearings, preventing wear and corrosion, and helping gears to dissipate heat. Gear transmission is one of the most important transmission methods in mechanical transmission. The gear transmission motion and power are completed by the meshing of the tooth surfaces of the gears. During this period, friction will inevitably occur. In order to maintain the service life of the gear mechanism, the meshing tooth surfaces need to be lubricated with lubricating oil. , Lubricating oil forms an adsorption film and a reaction film on ...
