Problems solved by technology

[0003] However, the current domestic common lubricating grease also has certain shortcomings, such as poor adhesion and poor protection when used at high temperatures for a long time. In addition, because the working environment of the wire rope often has rain, ice, snow, 2 , sulfur-containing gas, wind sand, salt spray, salt water and bacteria, etc., have a greater corrosive effect on steel wire and rope core

Abstract

The invention discloses a protective grease composition with high performance for a high-temperature-resistant steel wire rope and a preparation method thereof. The protective lubricating grease composition for the steel wire rope is prepared from base oil (high-viscosity mineral oil or synthetic oil), a thickening agent, an additive and a covering agent. The ordinary protective lubricating grease for the steel wire rope is prepared by thickening the base oil with a solid hydrocarbon thickening agent. The thickening agent disclosed by the invention is bentonite. A high-molecular-weight tackifier and a lubricating grease solid filler are adopted, so that the performance of bentonite lubricating grease is further improved, the protective lubricating grease for the steel wire rope has extremely high high-temperature resistance and extremely high adhesion strength, and low-cost protective grease with excellent combination property for the steel wire rope is provided. The protective grease for the steel wire rope is specially used for protecting the steel wire rope used in an extreme high temperature environment.

Description

technical field [0001] The invention relates to a lubricating grease composition, which is mainly used for high-temperature steel wire rope protection. Background technique [0002] Steel wire ropes are widely used in mining, fishery, machinery, tourism, transportation and other industries. With the development of my country's economic construction and the adjustment of industrial structure, wire rope users have higher and higher requirements for wire rope grease. Because the steel wire rope protective grease is constantly squeezed and seeped out by the steel wire rope during the entire service life of the steel wire rope to lubricate the steel wire rope. During the use of the steel wire rope, during the constantly changing pulling, slack, rolling, and traction process, motion friction often occurs between steel wires, between ropes and wheels, and between ropes and ropes. In some occasions, this frequency is very high, and the steel wire rope protective grease must maintai...
