Abstract

The invention provides food grade anti-bacterial corrosion-resistant lubricating grease which is prepared from the following raw materials in parts by weight: 100 parts of food grade base oil, 10-15 parts of a compound aluminum soap thickener, 5-12 parts of a compound anti-bacterial preservative, 3-6 parts of a cellulose ether additive, 3-6 parts of polyglycerol fatty acid ester, 0.3-0.8 part of dilaurate dipropionate, 2-6 parts of an organoboron compound SW-2, 0.2-0.8 part of methylphenyl silicone oil, 1-3 parts of an ethylene-propylene copolymer, 0.2-0.6 part of medical level propylene carbonate, 0.2-0.8 part of phytic acid and 1-3 parts of stearic acid. The lubricating grease provided by the invention for food machinery not only has excellent wear resistance and lubricating property, but also is anti-bacterial and excellent in corrosion resistance, and the lubricating environment is kept clean and the continuity of the lubricating property is kept; and the process is simple, and scaled industrial production and use are facilitated. Meanwhile, the lubricant provided by the invention can meet the lubricating demand on mechanical equipment in a processing course of the food industry, and meets the safety and sanitation demands on the food grade lubricant.

Description

technical field [0001] The invention relates to the technical field of lubricating grease, in particular to a food-grade antibacterial and antiseptic lubricating grease and a preparation method thereof. Background technique [0002] Food processing equipment is widely used as a necessary and basic facility for food production. At present, various mechanical devices and equipment are widely used in food processing. The internal and external mechanical devices and transmission parts of these devices are in operation and work. Lubricating grease is used to prevent wear and corrosion of mechanical parts or to reduce the heat generated by friction. Lubricating grease is extremely important for the normal operation of food processing equipment and is essential in some food processing enterprises, but if used improperly, it will lead to cross-contamination and food safety problems. [0003] Today's food processing industry faces serious challenges. On the one hand, the demand for...
