The invention discloses a protective wax for mechanical parts and a preparation method thereof. The modified curing agent is prepared by the following process: first, aniline, formaldehyde and concentrated hydrochloric acid with a concentration of 25% are introduced into a stirring tank together, heated to 55 After reacting for 3 hours at high temperature, neutralize it with sodium carbonate solution, then introduce ammonia water into it, after step-by-step precipitation, filter and remove impurities, the mixed solution is exported to the absorption tower, and then dilute sulfuric acid with a concentration of 30% At the same time, phosphine gas is introduced into it. Under the pressure of 1.5MPa and temperature of 65 degrees, it is absorbed by the absorption tower for 2 hours, and after recrystallization and purification with deionized water, it is filtered and cooled to obtain modified Curing agent; in the present invention, the solvent is evenly preheated and blended with other raw materials, so that each system is in a constant temperature premixed state, and then blended in batches in sequence, and then more violent molecular-level movement occurs. In order to obtain a protective wax with better consistency on the microscopic surface.
