[0062] The preparation method of the special lubricating grease for the harmonic reducer of the industrial robot, the specific process steps are as follows:
[0063] 1) Heat and mix all the base oil and tackifier in reactor A;
[0064] 2) Add 1 / 2 of the above-mentioned blending oil into the reaction kettle B, and dissolve the aliphatic amine and aromatic amine at 70-80°C;
[0065] 3) Dissolve the remaining blended oil in reactor A at 50-60°C to dissolve isocyanate;
[0066] 4) After being completely dissolved, the solution in steps 2) and 3) is finely filtered;
[0067] 5) Slowly add the aliphatic amine and aromatic amine solution into the isocyanate solution, and add an initiator to react at 80-100°C for 10-30 minutes;
[0068] 6) After the reaction is completed, raise the temperature to 150-200°C for 30-90 minutes;
[0069] 7) After cooling at 80-90°C, add multi-effect additives, extreme pressure anti-wear agents, and anti-rust agents in sequence, grind and homogenize to ...
