Heavy-load open-type gear lubricating grease and preparation method thereof

The invention discloses a heavy-load open-type gear lubricating grease and a preparation method thereof. The lubricating grease comprises the following components in percentage by weight: 57 to 80% of basic oil, 3 to 6% of composite aluminum thickening agent, 3 to 7% of extreme pressure anti-wear additive, 2 to 5% of oiliness agent, 5 to 10% of solid additive, 0.5 to 1% of antirust agent, 6 to 13% of tackifier, and 0.5 to 1.0% of antioxidant. The provided lubricating grease is developed on the basis of the conventional open gear lubricating grease, is capable of solving the problems that the production of conventional lubricating grease consume too much energy and the conventional lubricating grease contains substances that can pollute the environment, has the advantages of good adhesive performance and extreme pressure anti-wear performance, and can fully meet the requirements on restricted substances RoHS 2.0 in Europe Union. The friction resistance and the energy consumption are prominently ...
