Abstract
The invention relates to a flame-retardant environment-friendly high-temperature grease for a stokehole track and a preparation method thereof. The base oil is water-soluble polyether or bright stock, and when the base oil is bright stock, the high-temperature grease also comprises an emulsifier. The high-temperature grease has good application on a stokehole track, has high flame resistance, does not catch fire on a red iron plate at 600 ℃, has little smoke and little gas irritation; the paint does not contain black substances such as graphite, molybdenum disulfide and the like, and does not pollute the working environment; no heavy metal, easy post-treatment, little influence on environment, and maximum use temperature up to 1000 ℃.
Description
Technical Field
The invention relates to a flame-retardant environment-friendly high-temperature grease for a stokehole rail and a preparation method thereof, belonging to the technical field of lubricating grease.
Background
In addition to heavy load and serious dust pollution, the stokehole track bearing in the industries of metallurgy, steel, machining and the like also directly suffers radiation and baking of high-temperature iron (steel, copper and the like) water at the temperature of more than 900-1000 ℃ throughout the year, so that the risk of ignition is very high, and the working environment is extremely severe.
As is well known, molybdenum disulfide or graphite lithium-based grease, or composite calcium sulfonate grease added with molybdenum disulfide and graphite is commonly used for bearings in these working environments, and most of them use imported special lubricating grease. These greases have significant disadvantages: 1) the dropping point of molybdenum disulfide and graphite lithium-based grease is low, the use temperature is low, and grease loss is easy to cause during work; 2) a large amount of coke smoke is easily generated and even ignited in the using process; 4) the maximum service temperature of the molybdenum disulfide is 350 ℃, the maximum service temperature of the graphite is 500 ℃, and the service conditions of ultrahigh temperature cannot be met; 5) molybdenum disulfide is oxidized at high temperature, so that the molybdenum disulfide can generate corrosivity on metals; 6) molybdenum disulfide and graphite are black, and the working environment is seriously polluted; 7) the imported lubricating grease has high price, but the performance is not ideal, and the grease becomes thin and emits oil at high temperature, the smoke is heavy and the grease is easy to catch fire.
