Abstract

The invention discloses a roll bearing grease lubricant and a preparation method thereof. By utilizing a thickening agent, i.e. stearic acid, the roll bearing grease lubricant has a better water-drenching resistance; and the grease lubricant has better adhesivity by matching with adhesive and high-viscosity base oil, so that the grease lubricant is not easy to be washed off by water and has lubrication stability; by combining with addition agents including a water-resisting extreme-pressure anti-wearing agent, an anti-rusting agent and the like, the grease lubricant can guarantee the extreme-pressure lubrication of a bearing in the presence of a lot of water; and therefore, the roll bearing which utilizes the grease lubricant provided by the invention has better water-drenching resistanceand adhesivity, a lubrication stability and a compressive property of the bearing can be guaranteed by the grease lubricant in the presence of a lot of water, the bearing capability of the roll bearing is improved, the service life is prolonged, and the cost is saved.

Description

technical field [0001] The invention relates to lubricating grease for rotating machinery and a preparation method thereof, in particular to a roll bearing lubricating grease and a preparation method thereof. Background technique [0002] The roll is an important part of the rolling mill in the rolling mill. It uses the pressure generated when a pair or a group of rolls roll to roll the steel; to obtain the desired shape of the steel. Since the roll is a rotating part, and its surface is in direct contact with steel, the bearing not only acts as a common rotation support, but also bears a large radial pressure, so it must be lubricated to achieve normal operation. At the same time, due to the harsh operating environment of the roll, in addition to bearing high temperature and heavy load, it will also be impacted by cooling water, so it will seriously affect its lubrication state, and the lubrication state has a decisive effect on the operating state of the bearing. [0003]...
