Abstract

A weak-smell low-corrosion gear lubricant additive composition and a preparation method thereof comprise the following materials: an extreme pressure agent, an anti-wear agent, a friction modifier, an antirust agent, a metal deactivator, an antioxidant, and mineral base oil. During preparation, in a blending kettle, the materials are mixed well to transparency to form a gear lubricant additive. The invention has the advantages that this composition has weak smell, is free of stimulus and fluorine, has low environmental damage, and has good extreme pressure and anti-wear performances, emulsion resistance, anti-rust and anti-corrosion performance, oxidation resistance, and anti-foam performance.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil additives, and relates to a gear lubricating oil additive composition and a preparation method thereof, in particular to a low-odor, low-corrosion gear lubricating oil additive composition and a preparation method thereof. Background technique [0002] The extreme pressure agent component in the traditional gear lubricating oil additive composition uses T321 sulfurized isobutylene as the main agent. According to its production method, it is divided into chlorine-containing sulfurized isobutylene and chlorine-free high-pressure method sulfurized isobutylene. The products have strong irritation Odor, inhalation of a certain amount will cause dyspnea, irritate the respiratory tract, and easily cause people's physical discomfort. [0003] US2013149191A1 discloses "a kind of copper corrosion-resistant gear oil additive composition", the composition is in dialkyl polysulfide, or the mixture of d...
