Problems solved by technology

[0003] For many years, there has been no unified standard for light vehicle manual transmission oil. During the use of commonly used API GL-4 oil, sludge, paint film and deposits will appear in the transmission, resulting in seal leakage and synchronization failure.
[0004] At present, some related researches have partially optimized the above problems, but there are still some problems such as poor anti-foaming performance, poor wear resistance and durability, poor thermal stability and adaptability of sealing materials, low temperature performance and poor storage stability. defects, so a new technical solution is needed to solve the above problems

Abstract

The invention discloses a light vehicle manual transmission oil and a preparation method thereof. The light vehicle manual transmission oil is prepared from base oil, glycerin, thioether compounds, polybasic polycarboxylic acid, a metal passivator, a cleaning dispersant, a friction modifier, an antifoaming agent, an antioxidant, an antirust agent, a demulsifying agent and deionized water. According to the invention, through synergistic effects of various chemical solvents, particles in lubricating oil are strengthened in stability and are insusceptible to settling; and the particles in the lubricating oil have the advantages of strong stability, insusceptibility to settling and good lubricating performance, so friction can be effectively reduced; the loss is decreased; and phenomenons of seal leakage and lubrication failure of a synchronizer due to generation of oil sludge, paint film and deposits in a conventional transmission are prevented from occurring. In addition, the preparation method provided by the invention is simple and has low production cost; and the obtained light vehicle manual transmission oil has excellent antifoaming properties, thermal stability, wear resistance, good sealing material adaptability, excellent low-temperature performance, good storage stability, and applicability to large-scale production.

Description

technical field [0001] The invention relates to a vehicle lubricating oil and its preparation, in particular to a light-duty vehicle manual transmission oil and its preparation method. Background technique [0002] User expectations and economic legislation are the main drivers for the development of transmission fluid specifications. Motorists expect comfort and ease of shifting under all operating conditions. They also want the transmission to operate without problems or damage during the oil change interval. , to reduce maintenance costs and the loss of cars parked on the road due to damage to the transmission; the strong pressure of energy saving and emission reduction requires continuous reduction of vehicle fuel consumption. Of course, the improvement of the engine is the first, and the improvement of the transmission is also very important. Improvements in modern transmissions in terms of friction materials, selection of wheel mechanisms, and synchronizer design have ...
