Abstract

The invention discloses a gearbox protective coating solution. The gearbox protective coating solution is prepared from the following components by mass: 14-20 parts of hexadecyl nano calcium borate,14-20 parts of base oil 250N, 30-50 parts of base oil 60N, 3-5 parts of high-basic-value synthetic calcium sulphonate T106, 3-7 parts of zinc bis-octyl dithiophosphate T203, 0.1-0.5 parts of poly alpha-olefin, 2-9 parts of viscosity index improver and 0.001-0.01 parts of antifoaming agent for lubricating oil.

Description

technical field [0001] The invention relates to the field of gearbox wear and repair protection, in particular to a gearbox protective coating liquid and a preparation method thereof. Background technique [0002] The special oil for the gearbox is not only the transmission oil for the torque converter, but also the lubricating oil for the planetary gear structure and the hydraulic oil for the shifting device. Transmission oil has the function of transmitting hydraulic force and cleaning and lubricating, but the wear between parts will obviously reduce the quality of transmission oil, reduce the transmission efficiency and lubrication effect, and cause damage to various components, especially the oil pressure solenoid valve, friction plate wear and valve body damage , the impact of shifting is increased, the transmission efficiency is reduced, and the fuel consumption is increased. Contents of the invention [0003] An object of the present invention is to provide a metho...
