Abstract

The invention relates to a lubricating grease composition consisting of lubricating grease, liquid rubber and a peroxide crosslinking agent; the dropping point of the lubricating grease composition can be greatly increased in the using process, the lubricating grease composition is mainly used as long-life and high-dropping-point lubricating grease and an anti-rust and lubrication protective agent for steel wire ropes, and also can be used as a joint mixture for cement cracks of some buildings such as bridges and the like.

Description

technical field [0001] The invention relates to a lubricating grease composition, which belongs to the field of polymer chemical industry. The dropping point of the lubricating grease composition of the present invention can be greatly increased during use, and it is mainly used as a long-life high dropping point lubricating grease, as well as an antirust lubricating and protecting agent for steel wire ropes, and can also be used as cement for certain buildings such as bridges Gap sealant. Background technique [0002] Grease is a commonly used semi-solid lubricant. It is used for the friction part of the machine to lubricate and seal. It is also used on the metal surface to fill the gap and prevent rust. The common one is mainly used on the surface of the steel cable. Lubricates steel wire and prevents rust. It is generally required that the lubricating grease has good fluidity before use, that is, it is easy to smear, and is easy to add to the lubricating area. At the sa...
