Embodiment 1
[0022] This embodiment provides a production process for environmentally friendly hydraulic oil, comprising the following steps:
[0023] Step 1. Prepare materials
[0024] Weigh raw materials by weight: 60 parts of epoxy vegetable oil, 20 parts of triglyceride, 10 parts of polyacrylamide, 8 parts of polyethylene glycol, 6 parts of potassium dihydrogen phosphate, 5 parts of tricresyl phosphate, dioxane 2 parts of zinc dithiophosphate, 2 parts of nano-silicon nitride, 1 part of calcium sulfate, 0.5 parts of di-tert-butyl-p-cresol, and 1 part of paraffin;
[0025] Step 2. Mix and preheat
[0026] Put the above-mentioned raw materials except paraffin into a stirring tank and mix evenly, heat to 30°C, keep the stirring speed at 400r / min, and stir for 10min;
[0027] Step 3. Heating
[0028] Add paraffin wax to the preheated mixture in step 2, keep the stirring speed at 500r / min for 5min, and then heat the mixture to 60°C;
[0029] Step 4, cooling, filtration and distillation ...
