Commonly used sulfur-containing extreme pressure antiwear additives mainly include butylene vulcanized grease and vulcanized esters, thiocarbonates, dithiocarbamates, and polyalkali compounds.
Their sulfur content is 40% to 45%. This type of sulfide has good stability, high extreme pressure resistance, and light color, but the sulfur-containing extreme pressure agent has poor wear resistance. Because the sulfur-containing extreme pressure agent reacts chemically with the metal surface under high temperature and high pressure to form an iron sulfide film. Iron sulfide has good heat resistance, so the sintering load of sulfur-containing extreme pressure agents is high, but the iron sulfide film is brittle, so its wear resistance is poor.
A widely used product among sulfur-containing extreme-pressure antiwear additives is sulfurized iso-butylene (T321). It is characterized by high sulfur content, good oil solubility, and moderate chemical activity, so it is less corrosive to copper. It can be used as an extreme pressure agent for cutting oil, gear oil, hydraulic oil, metal processing oil, etc., and is especially suitable for the preparation of Gear Oil.
