Abstract

The invention discloses protective coating solution for gearboxes and a method for preparing the protective coating solution. The protective coating solution for the gearboxes comprises polytetrafluoroethylene, dispersing agents, base oil, viscosity index improvers and adhesive. The protective coating solution and the method have the advantages that the gearboxes can be repaired and can be protected by the protective coating solution against abrasion and deterioration of the transmission performance due to prolongation of the working time, damage to oil pressure electromagnetic valves, abrasion of friction plates and harm to valve bodies can be effectively reduced, the transmission efficiency can be improved, increase of oil consumption can be prevented, and gear shifting shock can be relieved.

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...
