Abstract

The invention provides a steel wire rope lubricating grease composition which comprises the following components, by weight: 54-65 parts of base oil, 15-25 parts of a thickening agent, 15-35 parts of a tackifier, and 1-10 parts of an additive. The steel wire rope lubricating grease with a high dropping point is obtained by optimally proportioning the types and dosages of the base oil, the thickening agent, the tackifier and the additive, and the problem that the lubricating grease drips at a high temperature is solved. The dropping point of the steel wire rope lubricating grease can reach over 95 DEG C, so that the high-temperature use requirement is met. The invention also provides a preparation method of the steel wire rope lubricating grease composition.

Description

technical field [0001] The invention belongs to the technical field of lubrication, and in particular relates to a steel wire rope lubricating grease composition and a preparation method thereof. Background technique [0002] With the development of modern industry, the operating conditions of wire ropes are becoming more and more harsh, and they need to work under high temperature conditions. Therefore, the requirements for wire rope grease are also becoming more and more stringent. However, the existing lubricating grease generally has the problem of low dropping point. Therefore, it is necessary to increase the dropping point of the wire rope lubricating grease so that it will not drip due to melting at high temperature and meet the requirements of high temperature use. Contents of the invention [0003] In view of this, the object of the present invention is to provide a steel wire rope grease composition and a preparation method thereof. The steel wire rope grease com...
