Environmentally friendly grease and preparation method thereof

Abstract

The invention provides environmentally friendly grease. The grease is characterized in that the grease is prepared from, by weight, 20-50% of environmentally friendly grease precursor and 50-80% of poly castor oil acid ester. According to the grease, beeswax has a pleasant and fragrant smell and can be used for improving a working environment, the beeswax reacts with borate to generate organic borate, the organic borate has better friction reducing and rust resisting effects, the poly castor oil acid ester has higher kinematic viscosity, the poly castor oil acid ester does not easily escape from a grease structural system to affect the service life of the grease, and the components of the grease are obtained from natural raw materials, so that the grease is good in environmental protectionperformance.

Description

technical field

[0001] The invention belongs to the technical field of lubricating grease, and in particular relates to an environment-friendly lubricating grease and a preparation method thereof. Background technique

[0002] The traditional grease processing technology is: add animal and vegetable oil or fatty acid to inorganic base (such as sodium hydroxide, calcium hydroxide, lithium hydroxide, aluminum hydroxide, barium hydroxide, etc.) to prepare metal soap as thickener or use organic or Inorganic thickener, which is thickened by adding mineral oil or synthetic oil, is mainly to store mineral oil or synthetic oil in the framework of thickener, and store it in the thickener under the action of motion pressure and temperature. The oil in the thickener escapes and acts as a lubricant. It exhibits paste-like physical properties at normal temperature and pressure. However, after a period of time, the oil will naturally escape and separate from the frame formed by the thicke...
