Problems solved by technology

At present, most of the steel wire ropes used for metallurgical lifting steel wire ropes for hoisting ladles are 6×19w+IWR structural steel wire ropes. From the perspective of steel mills and enterprises tracking the quality of their steel wire ropes, there are problems such as wire rope sheathing, many broken wires, and the service life of steel wire ropes. Relatively short (less than 6 months) and other quality problems
Existing technologies such as CN201410743867.6 A hot-coated elevator steel wire rope grease and its preparation method The steel wire rope grease is only suitable for working conditions at 80°C, and CN200910182033.1 introduces a flame-retardant grease and its The preparation method has problems such as low dropping point and large oil separation, and is not suitable for the high-temperature radiation working conditions of steel mills. Therefore, the high-dropping point flame-retardant wire rope grease required for high-temperature radiation working conditions of steel mills has not been reported in the prior art.

Abstract

The invention relates to a high-dropping-point flame-retardant steel wire rope lubricating grease composition, which is characterized by comprising the following components by weight: 70-90 parts of polyurea lubricating grease; 1-5 parts by weight of an adhesive; 1-5 parts by weight of a flame retardant; 0.1-1 part by weight of an anti-wear agent; 0.3-1.0 part by weight of an antioxidant; and 0.1-0.5 part by weight of an antirust agent, wherein the sum of the components is 100 wt%, the flame retardant is one or more of alkyl phosphate, such as tributyl phosphate, tris(2-ethylhexyl) phosphate,tris(2-chloroethyl) phosphate and tris(2,3-dichloropropyl) phosphate. The steel wire rope lubricating grease with high dropping point and flame retardancy is high in dropping point, low in high-temperature oil separation and capable of self-extinguishing lubricating grease, and even if the lubricating grease is on fire, fire propagation can be prevented within a few seconds, so that a steel wire rope is effectively lubricated, and the effect of prolonging the service life is achieved.

Description

technical field [0001] The invention relates to the technical field of lubricating grease, in particular to a high dropping point flame retardant steel wire rope lubricating grease composition and a preparation method and application thereof. [0002] technical background [0003] Steel mills require high-performance greases to handle the harsh operating conditions of blast furnaces, coke ovens, continuous casting, thermal units, etc. At present, most of the steel wire ropes used for metallurgical lifting steel wire ropes for hoisting ladles are 6×19w+IWR structural steel wire ropes. From the perspective of steel mills and enterprises tracking the quality of their steel wire ropes, there are problems such as wire rope sheathing, many broken wires, and the service life of steel wire ropes. Relatively short (less than 6 months) and other quality problems. How to improve the service life of the crane steel wire rope used for hoisting ladles is a matter of great concern to manuf...
