Abstract:
     The said wearing agent is a condensation compound of diathiophosphoric acid, fatty amine, paraform and epoxy propane. In the present invention, the use of solid paraform rather than formaldehyde solution results in simplified technological process and decreased waste water, and the treatment of using epoxy propane improves the copper corrosivity of the product. The product produced based on the present invention may be used for compounding gear oil for extreme-pressure industrial gears and automobile hyperbola gears, which has excellent extreme-pressure resistance and wearability.
