The invention discloses an antioxidant, a grease composition and a preparation method. The antioxidant contains a triazine-2,4,6-triketone body, and substituted phenol groups and substituted ester groups or thioether ester groups at positions 1, 3, and 5, and the specific structural formula is as described in the specification The molecular structure is shown in general formula I. The grease composition contains the antioxidant of the present invention. The lubricating grease composition of the present invention contains the antioxidant of the present invention, which can efficiently capture terminated chain radicals to prevent oxidation of the lubricating grease composition, thereby reducing the aging of the lubricating grease composition and prolonging the use of the lubricating grease composition. life, thereby imparting excellent antioxidant properties to the grease composition. At the same time, the lubricating grease composition also has good water resistance and anti-wear extreme pressure properties, and the conditions of the preparation method are controllable, so as to ensure the stable performance of the prepared lubricating grease composition. |
