Abstract

The invention relates to the field of lubricating oil, and particularly discloses a composition used for food-grade gear oil, a preparing method thereof, gear oil including the composition and a preparing method of the gear oil including the composition. The composition includes, by weight, 5-10 parts of a food-grade antioxidant, 10-25 parts of a food-grade antiwear agent, 0.5-1.5 parts of a food-grade metal deactivator, 1.0-2.5 parts of a food-grade antirust agent, 0.5-1.5 parts of a food-grade corrosion inhibitor, 0.2-1.0 part of a food-grade oiliness agent, 0.1-0.5 part of a food-grade anti-emulsification agent and 0.01-0.3 part of a food-grade defoamer, with the balance being food-grade base oil A and the total weight parts being 100 parts. The composition and the gear oil including the composition have excellent waterproofness, oxidation resistance, wear resistance, extreme pressure properties, micro pitting resistance, rust resistance, emulsification resistance and foam resistance, can effectively meet requirements on heavy duty, extreme pressure properties, wear resistance, emulsification resistance, rust resistance, micro pitting resistance, and the like of gear systems in a food processing process, are nontoxic and harmless and do not contaminate foods.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a composition for food-grade gear oil and a preparation method thereof, as well as a gear oil containing the composition and a preparation method thereof. Background technique [0002] In food production, lubricating oils with high safety performance are required for the hydraulic pressure, gears, turbines, bearings, chains, etc. of mechanical equipment, not only to meet the lubrication requirements of food machinery, but also to meet the requirements of food safety. Such lubricating oils are collectively referred to as For food grade lubricants. [0003] Food-grade lubricating oil is a lubricating oil that does not cause any physiological harm to consumers when it comes into contact with food during the production process, and does not have any impact on the smell and taste of food. It is formulated from base oil and additives. The base oil generally adopts hydrocracked refined m...
