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...

Abstract

The invention discloses synthetic lubricating oil for food machinery and a preparation method thereof. The lubricating oil comprises natural gas synthetic oil, alkyl naphthalene base oil and other additives. All the components in the invention accord with FDA regulations 21CFR178 3570, so that all the components are safe and non-toxic and meet the hygienic requirements of national food-grade lubricating oil, and the food-grade multipurpose oil prepared based on the components can be used for equipment or mechanical parts possibly making accidental contact with food in the food processing process and meets the requirements of American Health Foundation NSF H1 type lubricants. The lubricating oil is reasonable in components, good in viscosity-temperature performance, high in oil film retentivity and outstanding in lubricating performance; the thermal oxidation stability is outstanding and the service life is long; and the lubricating oil provided by the invention has outstanding wear resistance, rust resistance, corrosion resistance, water resistance and the like, is high in universality, can meet the lubricating requirements of various lubricating places in the food processing process, simplifies inventory management, is non-toxic and harmless, does not pollute foods, and does not pollute products and influence food safety even if volatilization or leakage of mechanical equipment occurs.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a synthetic lubricating oil for food machinery and a preparation method thereof. Background technique [0002] Food-grade lubricants are mainly used in the food industry. The hydraulic pressure, gears, turbines, bearings, chains, etc. of mechanical equipment need to use high-safety lubricants, not only to meet the lubrication requirements of food machinery, but also to meet food safety requirements at the same time. The requirements must not contaminate the product and affect food safety. Food-grade lubricating oil is composed of base oil and additives. The base oil must have very good anti-oxidation, high and low temperature resistance, and anti-emulsification properties. It has a long service life, can reduce equipment wear, prolong the service life of equipment, and reduce maintenance frequency; at the same time , does not contain toxic substances, and will not cause pollution ...
