Problems solved by technology

The surface grease of the hydrocarbon-based steel wire rope is paste-like at room temperature, which leads to heavy pollution on the construction site; under the sunlight in summer, the surface grease of the hydrocarbon-based steel wire rope is easy to melt and flow; and in winter, the surface grease of the hydrocarbon-based steel wire rope is easy to crack and fall off, which brings a lot of inconvenience to production operations
[0004] Foreign port machinery wire rope grease has a high degree of recognition in domestic ports and a large market share, but its product stability is slightly poor, low temperature performance cannot meet the needs of domestic northern ports, and poor wear resistance cannot meet long-term operation
At present, domestic steel wire rope grease manufacturers are mostly concentrated in the low-end general-purpose field, and there are few breakthroughs in high-temperature performance, low-temperature performance, and anti-wear performance.

Abstract

The invention provides a steel wire rope lubricating grease composition and a preparation method thereof. The preparation method comprises the following steps: adding the base oil, fatty acid and acetic acid into a reaction kettle, heating the mixture to 80-85 DEG C, adding barium hydroxide octahydrate, and heating the mixture to 90-100 DEG C for saponification; after saponification is finished, heating the mixture to T1, and adding the balance of base oil, polyethylene wax and polyisobutene; continuously heating the mixture to T2, keeping the temperature for 30-60 minutes, then reducing the temperature, adding an extreme pressure agent when the temperature is reduced to below 80 DEG C, uniformly mixing the components, and then degassing the components to obtain the steel wire rope lubricating grease composition. By adding the composite barium-based lubricating grease into the alkyl lubricating grease, the prepared lubricating grease has excellent high and low temperature properties, adhesion, hydrophobicity, rust resistance and wear resistance and durability, and can meet the temperature and service life requirements of steel wire ropes for all ports in our country.

Description

technical field [0001] The invention relates to the field of chemical engineering, in particular to a steel wire rope lubricating grease composition and a preparation method thereof. Background technique [0002] Wire ropes are widely used in many industries related to the national economy and people's livelihood, such as mining, metallurgy, tourism, fishery, construction, machinery, etc. During the use of steel wire ropes, broken wires and scrapping caused by improper use and maintenance are not uncommon. The equipment using a large number of steel wire ropes has harsh working conditions, and the service life of the steel wire ropes is greatly shortened due to corrosion and insufficient lubrication. Steel wire rope grease is a kind of grease coated on the surface of strands and twisted steel wire ropes. On the one hand, its function is to reduce the friction between the steel wires in the strands and the friction between the steel wire rope and the wheel groove during the ...
