Abstract

The invention relates to a lubricating grease composition and a preparation method thereof, in particular to a composition of food-grade lubricating grease and a preparation method thereof. The composition comprises the following components in percentage by weight: 75-86 percent of base oil, 1.0-3.0 percent of benzoic acid, 3.5-6.5 percent of stearic acid, 3.5-7.0 percent of aluminum isopropoxide tripolymer, 0.5-1.5 percent of silicone oil, 1-5 percent of calcium carbonate, 0.2-1.0 percent of antioxidant and 0.5-2.0 percent of antirust agent. The lubricating grease composition has excellent high temperature resistance, water resistance and excellent anti-rust property, is greatly improved in water spray resistance and mechanical stability, and is simple in process and convenient for large-scale industrial production. The lubricating grease can meet the lubricating requirements of mechanical equipment used for meat processing, can processing, beverage processing and the like in the food industry, and is consistent with the safety and sanitation requirements of food-grade lubricants.

Description

technical field [0001] The invention relates to a lubricating grease composition and a preparation method thereof, in particular to a food and lubricating grease composition and a preparation method thereof, and belongs to the field of chemical technology. Background technique [0002] With the improvement of people's living standards, food safety has become a hot issue that people pay more attention to. In the process of food processing, it is necessary to widely use mechanical devices and equipment to carry out product transportation, packaging, drying, puffing, compression, etc., such as presses, mixers, food and beverage filling machines and other equipment, the internal and external machinery of these equipment During the operation and work of the device and the transmission part, lubricating grease is used to prevent the wear and corrosion of mechanical parts, reduce the heat generated by friction, and provide a good sealing function. In the process of using these lub...
