Temperature-variation-resistant antirust grease applicable to outdoor steel rails and preparation method of temperature-variation-resistant antirust grease

Abstract

The invention discloses temperature-variation-resistant antirust grease applicable to outdoor steel rails. The temperature-variation-resistant antirust grease is characterized by being prepared from the following raw materials in parts by weight: 9-13 parts of 550# machine oil, 12-16 parts of 120# solvent oil, 6-8 parts of neutral barium dinonyl naphthalene sulfonate, 1-2 parts of poly-alpha olefin, 1-2 parts of 2,6-di-tert paracresol, 1-2 parts of sorbitan monooleate, 2-3 parts of cocoanut active charcoal, 38-45 parts of wool grease, 20-27 parts of vaseline, 0.6-1 part of succinimide and 2.5-4 parts of a protective agent. The temperature-variation-resistant antirust grease is scientific and reasonable in formula; by adding poly-alpha olefin as a pour point depressant, the low temperature condensation is prevented; by adding the protecting agent, the antirust grease has good waterproof and lubricating effects, and a firm hydrophobic membrane can be formed on the surface of metal, so that rusting caused by corrosion of water and oxygen is prevented. The temperature-variation-resistant antirust grease is stable in performance and capable of resisting high and low temperatures, sun screening and rainwater impact, can well protect the metal and is applicable to the rust protection of the outdoor steel rails and the like, and films are stable.

Description

technical field [0001] The invention relates to the field of antirust liquid, in particular to antirust grease suitable for outdoor steel rails with temperature resistance and a preparation method thereof. Background technique [0002] There are many types of anti-rust grease, which are usually used for packaging and sealing of various mechanical parts, and anti-rust for railway track bolts and rails, which require good temperature resistance. Most of the antirust greases with paraffin wax as the thickener need to be heated when the oil seal is opened, the operation is complicated, and the thermal stability and anti-oxidation stability are difficult to meet the requirements, while the antirust grease containing metal ions will accelerate the surface oxidation, The anti-rust period is short in harsh environments, especially in outdoor environments, and if the temperature is too low, the anti-rust grease will solidify, which reduces the anti-rust effect and is inconvenient to ...
