Problems solved by technology

[0004] However, in foreign countries, because of the impact of barium and phosphorus-containing additives on human health and the environment, they have been restricted or banned. Therefore, we have developed an environmentally friendly anti-wear and anti-rust chain grease to meet the requirements of health and the environment.

Abstract

The invention relates to environment-friendly anti-wear rust-proof chain lubricating grease. The environment-friendly anti-wear rust-proof chain lubricating grease is prepared from, by weight, 20-85%of basic oil, 5-20% of tackifier, 5-35% of densifier, 0.1-5% of antioxidant, 5-30% of antirust agent, 0.1-1% of metal passivant and 0.1-5% of anti-wear extreme pressure reagent. The lubricating greasehas the high salt spray corrosion resistance, rust-proof performance and anti-wear extreme pressure performance, and the requirements for rust prevention, sea transportation and lubrication of a chain are met. Meanwhile, the lubricating grease contains no barium or phosphorus element, no harm is caused to the human health and environment, and the lubricating grease is safe and environmentally friendly to use.

Description

technical field [0001] The invention relates to the field of lubricants, in particular to an environment-friendly anti-wear and anti-rust chain lubricating grease. Background technique [0002] Antirust agents containing metallic barium elements have been used for decades at home and abroad due to their excellent salt spray resistance and antirust performance, such as barium petroleum sulfonate (T701) and dinonylnaphthalenesulfonate, which are widely used at present. Barium acid T705, neutral barium dinonyl naphthalene sulfonate T705A, barium alkylbenzene sulfonate, etc. Phosphorus-containing organic compounds, as excellent lubricating oil anti-wear extreme pressure additives, are also widely used products at present, such as: tricresyl phosphate (T306), dialkyl dithiophosphate amine salt (T305, T307), dioxane Zinc dithiophosphate (T202, T203, T205, etc.), dibutyl phosphite (T304), etc. [0003] At present, the anti-wear and anti-rust chain greases used in China basically ...
