Abstract

The invention discloses a multifunctional lubrication additive comprising the following components in parts by weight: 30-40 parts of extreme pressure antiwear agent and PN-containing additives, 10-25 parts of sulfurized isobutene, 10-20 parts of amine sulfuric-phosphoric diester, 50-60 parts of oleic acid epoxy ester as an oiliness additive, 1-5 parts of 9-octadecenoic acid (Z)-, [(2-hydroxyethyl) imino]di-2,1-ethanediyl ester as an antirust additive and a corrosion inhibitor and 5-10 parts of thiadiazole derivative and benzotriazole derivative mixture as a metal deactivator. The invention has the advantages that a plurality of industrial gear oil complex additives with different specifications can be compounded due to the addition of a plurality of components in the extreme pressure antiwear agent.

Description

technical field [0001] The invention relates to the technical field of lubricating oil additives, in particular to a multifunctional lubricating additive. Background technique [0002] Due to the different performance requirements of gear oil and worm gear oil, gear oil and worm gear oil are not universal at present, and in some factories, gears and worm gears share the same oil tank, and the gear oil contains sulfur or atmosphere such as sulfurized olefins. The additives have a strong corrosive effect on copper. At present, the gear oils on the market are mainly sulfur or chlorine pressure additives, while the worm gear oils are mainly oily agents, so gear lubricants are generally not suitable for the lubrication of worm gears. Industrial gear oil compounding agent is a compounding agent used to prepare medium-duty industrial gear oils of various viscosity grades, and its dosage is one of the most important indicators to measure the level of the compounding agent and its te...
