Embodiment 1
[0029] Embodiment 1: the preparation method of a kind of synthetic food machinery lubricating oil in the present embodiment is:
[0030] Firstly add natural gas synthetic oil and alkyl naphthalene base oil with a total amount of 45-55wt% of the formula into the blending kettle, start stirring, the stirring temperature is 50°C±2°C, and the stirring speed is 100±10r / min. Keep the temperature and stirring speed, add food-grade anti-oxidant and anti-corrosion agent, food-grade anti-wear agent, food-grade metal passivator, food-grade pour point depressant, food-grade rust inhibitor, food-grade corrosion inhibitor and the remaining The natural gas synthetic oil and alkyl naphthalene base oil, continue to maintain the stirring temperature of 50 °C ± 2 °C, the stirring speed of 100 ± 10 r / min, stirring and blending for 1 to 2 hours. Then add food-grade free water catcher and food-grade defoamer in sequence. Turn off the heat and cool to room temperature with stirring. The stirring t...
