Problems solved by technology

Dry friction between metal surfaces not only increases the power consumption of the gearbox and accelerates the wear of the working surface of the parts, but also may burn the working surface of the parts due to the heat generated by the friction, resulting in the failure of the gearbox
At the same time, it is easy to generate high temperature during driving. When the temperature exceeds 140°C, even the lubricating oil loses its lubricating effect, which will seriously affect the life of the car and the safety of the driver.

Abstract

The invention discloses lubricating oil for gearboxes and a preparation method thereof. The lubricating oil for gearboxes is prepared by: adding antimony oxide, cerium oxide, neodymium oxide and lanthanum oxide into a grinder, grinding and mixing well, adding glycerin, and ultrasonically dispersing for 5-10 min to obtain mixture A; adding tetraethyl silicate and n-phenyliminodiacetic acid, and stirring to allow reaction at 90-100 DEG C for 30-40 min to obtain mixture B; mixing 5-amino-2-benzimidazolinone, dibenzyl disulfide, tricresyl phosphate, sorbitol and 2,6-di-tert-butyl-p-cresol, and stirring to allow reaction at 60-80 DEG C for 20-30 min to obtain mixture C; adding the mixture A, the mixture B and the mixture C into basic oil, performing intensive shear stirring at 180-200 DEG C for 0.5-1 h, continuously heating to 250-280 DEG C, and performing shear stirring for 1-2 h; cooling to 120-140 DEG C, continuously performing shear stirring for 2-3 h, and cooling to obtain the lubricating oil for gearboxes.

Description

technical field [0001] The invention belongs to the field of lubricating oil, in particular to a lubricating oil for a gearbox and a preparation method thereof. Background technique [0002] Along with people's continuous requirements for the driving performance of automobiles, the improvement of automobile technology advances by leaps and bounds, which promotes the transformation of automobile gearboxes, and automatic gearboxes emerge as the times require. Automatic transmission, that is, the use of planetary gear mechanism to change speed, it can automatically change speed according to the degree of accelerator pedal and the change of vehicle speed. The driver only needs to operate the accelerator pedal to control the speed of the vehicle. Through the use of automatic transmission, in the process of automatic shifting, not only can the acceleration of the car become simpler and save effort, but also can effectively improve the comfort and safety of the car; reduce carbon ...
