Problems solved by technology

In the prior art, soap base is often added to the base oil to enhance the extrusion performance of the grease. However, if too much soap base is added, it is difficult to ensure that other physical properties of the grease are compatible with the amount of soap base added. Sometimes Even the opposite effect

Abstract

The invention discloses extreme pressure composite lubricating grease and belongs to the technical field of lubricating grease. The lubricating grease is prepared from, by part, 100-120 parts of base oil, 30-40 parts of thickening agents, 2-5 parts of waterproof agents, 10-20 parts of extreme pressure anti-wear reagents and 15-30 parts of peptizing agents through reaction; the base oil is composed of polyolefin and fluorocarbon oil, and the thickening agents are composite soap base thickening agents. According to the extreme pressure composite lubricating grease, due to the special combination of the thickening agents and the base oil, and the extreme pressure anti-wear reagents with borate and boric acid ester components, the extreme pressure resistance is greatly improved while the better physical performance of the lubricating grease is ensured; the waterproof property is achieved, corrosion to metal is avoided, and the lubricating grease is environmentally friendly and has good practicality.

Description

Technical field [0001] The invention belongs to the technical field of lubricating grease, and specifically relates to an extreme pressure composite lubricating grease. Background technique [0002] Lubricating grease is a thick, grease-like semi-solid, used for the friction part of the machine, for lubrication and sealing. It is also used on metal surfaces to fill gaps and prevent rust; it is mainly made of mineral oil (or synthetic lubricating oil) and thickener. [0003] When the traditional grease is used, it is applied to the metal surfaces in contact with each other to carry the axial and radial compound characteristics, which is called the squeezability of the grease. In the prior art, soap is often added to the base oil to enhance the extrusion performance of the grease. However, if the soap is added too much, it is difficult to ensure that the other physical properties of the grease are compatible with the added amount of the soap. It is even the opposite effect.
