Open-type gear grease composition

Abstract

The invention provides an open gear grease composition, which comprises the following components and the weight percentage contents are that gelatinizer 2-6%, mineral oil 20-60%, synthetic oil 20-60%, antioxidant 0.3-1%, oil solubility anti-wear extreme pressure additive 1-15%, solid additive 3-20% and rust inhibitor 1-3%. The open gear grease composition of the invention does not contain dissolvent and bitumen, which has no harmless to environment, and solves the problems that bitumen-type open gear oil has bad pollution and low-temperature performance, and the flowability of open gear grease is bad. The open gear grease composition has outstanding water resistance, adhesiveness and antiwear and extreme pressure property.

Description

technical field

[0001] The present invention relates to a lubricating oil, in particular to an open gear lubricating grease composition applied to large equipment. Background technique

[0002] Lubricants for open gears not only need good anti-wear and extreme pressure properties, but also good adhesion and suitable fluidity. At present, open gear lubricants mainly include asphalt-type open gear oil, high-viscosity gear oil, and open gear lubricating oil.

[0003] Asphaltene and its solvent-diluted open gear oil is a traditional oil in open gear oil. It is based on asphaltene and added with certain functional additives. It is heated to soften before use or some volatile solvents are added. Spray it before use. Or paint, after the solvent volatilizes, a layer of plastic rubber covers the tooth surface, which can prevent wear, dust and water damage. For example, the application number is 200410049765.0, and the name of the invention is a kind of open gear oil, with petroleum...
