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