The high anti-wear properties of lubricating grease are challenged by some machinery and equipment, so human beings are required to prepare more anti-wear lubricating grease. At presen...

Abstract

The invention relates to a slide rail lubricating grease composition which comprises the following raw material components in parts by weight: 80-94 parts of base oil, 4-12 parts of soap-base thickening agents, 0.5-2 parts of anti-abrasion additives, 0.5-8 parts of antirust additives and 1-2 parts of antioxidant additives. According to the slide rail lubricating grease composition, lanthanum fluoride, calcium acetate and thiocarbamate can reduce the friction coefficient of lubricating grease as the anti-abrasion additives; the lubricating grease which contains calcium acetate generates friction chemical reaction under the action of relatively high load and friction heat to generate CaCO3, CaCO3 further reacts to generate CaO and CaC2, and CaO and CaC2 have better anti-abrasion effects.
