Abstract

The invention relates to ultra-high temperature lubricating grease and a production method thereof, which belongs to the technical field of lubricant in the chemical industry. The production method comprises the following steps: adding synthetic ester oil and silicon dioxide powder to a reaction vessel for stirring, temperature rising, reacting, and heat insulating; adding an anti-wear agent, aquadag, metal powder, boron nitride and antioxidant, and then fully stirring and refluxing; and filtering, grinding, and obtaining the finished product. Because silicon dioxide inorganic thickener is adopted to thicken the ester oil, the ester oil is used as the basic lubricating grease which has good high-temperature resistance, without oil dripping, draining, coking and carbon accumulation at hightemperature, and various high temperature additives including graphite, metal powder and boron nitride are added, lubrication under the ultra-high temperature condition can be ensured, and bearing sintering can be prevented; lubrication in special positions and high temperature positions can be achieved, and the service life of equipment can be prolonged.

Description

technical field [0001] The invention relates to an ultra-high temperature lubricating grease and a production method, belonging to the technical field of lubricating materials in the chemical industry. Background technique [0002] In the prior art, ultra-high temperature lubricating grease is usually made by mixing 10-25 parts of lithium-based thickener, 40-60 parts of thickened mineral oil, and 20-60 parts of some solid lubricants such as graphite. This kind of lubricating grease is usually used at a high temperature of 600°C-800°C for the lubrication of high-temperature parts of equipment in steelmaking, printing and dyeing, papermaking and other industries. During use, it is easy to drip oil, lose oil, coke and carbon deposits at high temperatures, resulting in bearing damage; smoke will be emitted during use, which will have an impact on the human body and the environment. Contents of the invention [0003] The purpose of the present invention is to overcome the abov...
