Abstract

The invention discloses lubricating grease for protection of an equipment surface. The lubricating grease comprises, by weight, 65-80 parts of base oil, 10-26 parts of a hydrocarbyl-containing thickener, 6-22 parts of a thickening agent, 0.5-3.0 parts of lanolin calcium soap, 0.5-8.0 parts of barium petroleum sulfonate and 1.0-3.0 parts of an extreme pressure agent. The base oil has kinematic viscosity of 15.0-30.0mm<2> / s at a temperature of 60 DEG C and comprises one or more of naphthenic oil, silicone oil and poly-alpha-olefin synthetic oil. The thickening agent is random polypropylene or an amorphous alpha olefin copolymer. The lubricating grease solves the problem that the existing grease leaks, utilizes APP or APAO as the thickening agent, improves a lubricating grease dropping point, improves adhesion, has excellent antirust and anti-corrosive properties and satisfies equipment surface protection requirements. The lubricating grease has effects of resisting water, sealing and preventing rust and corrosion.

Description

technical field [0001] The invention relates to the field of lubricating grease, in particular to a lubricating grease for protecting the surface of equipment. Background technique [0002] Grease is a thick grease-like semi-solid, which is used for the friction parts of machinery to lubricate and seal. It is also used on metal surfaces to fill voids and prevent rust. It is mainly formulated with mineral oil or synthetic lubricating oil and thickener. [0003] The working principle of grease is that the thickener keeps the oil in the position that needs to be lubricated, and when there is a load, the thickener releases the oil to lubricate. It is like a solid at room temperature and at rest, can maintain its shape without flowing, and can adhere to metals without slipping. At high temperature or when subjected to an external force exceeding a certain limit, it can flow like a liquid. When the grease is sheared by the moving parts in the machine, it can flow and lubricate...
