What is the composition of grease?

  Basic composition

  The oil is mainly composed of thickener, base oil additive. Most of them are used in mechanical equipment. The content of thickener in general lubricating grease is about 10% - 20%, the content of base oil is about 75% - 90%, the content of additives fillers is less than 5%.

  1. Crude oil

  Base oil is the dispersing medium in the oil dispersing system, which has a great influence on the performance of oil. In general, most lubricants use medium viscosity high viscosity oil as base oil. There are also some synthetic lubricants as base oils, such as ester oil, silicone oil, etc. Polyalkene oil, etc.

  2. Thickener

  Thickener is an important component of oil. The thickener is dispersed in the base oil forms the structural framework of the grease, so that the base oil is adsorbed fixed in the structural framework. The water resistance heat resistance of the grease are mainly determined by the thickener. There are two kinds of thickeners for preparing oil. Soap thickener (i.e. fatty acid metal salt) non soap thickener (hydrocarbon, inorganic organic matter).

  Soap thickeners can be divided into three types: single soap base (such as calcium base fat), mixed soap base (such as calcium sodium base fat) compound soap base (such as compound calcium base fat). 90% of the grease is made of soap based thickener.

  3. Additives fillers

  Lubricating grease needs an additive, called glue solvent. Can it make oil soap combination more stable? Such as glycerin water. Once the calcium based grease loses water, its structure will be completely destroyed will form fat. For example, glycerin can adjust the consistency of fat in sodium grease. Other types of additives are the same as those in lubricating oil, such as anti-oxidation, anti-wear anti rust agents, but the amount of additives is usually larger than that in lubricating oil. Such as phosphate ester, ZDDP, Elco extreme pressure antiwear agent, compound agent, drop point enhancer, etc. Sometimes, graphite, molybdenum disulfide carbon black are often added to improve the loss resistance lubricity of lubricating grease. As filler.
