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...

Abstract

The application discloses a synthetic lubricating oil for food machinery and a preparation method thereof, wherein the lubricating oil includes natural gas synthetic oil, alkyl naphthalene base oil and other additives. All ingredients in this application comply with FDA regulations 21CFR178 3570, all components are safe and non-toxic, and meet the national food-grade lubricant hygiene requirements, and the food-grade multi-purpose oil prepared based on this component can be used in food processing On equipment or mechanical parts that may have accidental contact with food, meet the requirements of the US Sanitation Foundation NSF H1 category lubricants. Reasonable composition, good viscosity-temperature performance, high oil film retention, outstanding lubricating performance; outstanding thermal oxygen stability, long service life; outstanding anti-wear, anti-rust, anti-corrosion, water resistance and other properties, strong versatility, can meet the needs of food processing The lubrication needs of various lubrication places in the process simplify inventory management, and it is non-toxic and harmless, and has no pollution to food. Even if there is volatilization or leakage of mechanical equipment, it will not pollute the product and affect food safety.

Description

technical field [0001] The invention relates to the field of lubricating oils, in particular to a synthetic lubricating oil for food machinery and a preparation method thereof. Background technique [0002] Food-grade lubricating oil is mainly used in the food industry. The hydraulic oil, gear, turbine, bearing, chain, etc. of its mechanical equipment need to use lubricating oil with high safety performance, not only to meet the lubrication requirements of food machinery, but also to meet food safety requirements. requirements, not to contaminate the product and affect food safety. Food-grade lubricating oil consists of base oil and additives. The base oil must have very good anti-oxidation, high and low temperature resistance and anti-emulsification properties, and has a long service life, which can reduce the wear and tear of equipment, prolong the service life of equipment, and reduce maintenance frequency; at the same time , also contains no toxic substances and will no...
