The technical scheme of the invention is as follows:
a lubricating oil base oil light stabilizer composition comprises the following components in parts by weight: 10-30 parts of antioxidant, 20-50 parts of detergent, 20-50 parts of dispersant and 10-20 parts of ultraviolet absorber.
Preferably, the lubricating oil base oil light stabilizer composition comprises the following components in parts by weight: 12-30 parts of antioxidant, 20-45 parts of detergent, 20-45 parts of dispersant and 12-20 parts of ultraviolet absorber.
Preferably, the lubricating oil base oil light stabilizer composition comprises the following components in parts by weight: 20 parts of antioxidant, 30 parts of detergent, 31 parts of dispersant and 19 parts of ultraviolet absorber.
Further, the antioxidant comprises one or more of T501, T512 and the like; preferably T512.
Further, the detergent comprises one or more of T101, T102, T104, T105 and the like; preferably T104.
Further, the dispersant comprises one or more of T151A, T151B, T152, T161A and the like; preferably T161A.
The invention also provides a preparation method of the lubricating oil base oil light stabilizer composition, which comprises the step of uniformly mixing all the components according to the proportion.
The raw materials of the invention are all available on the market.
The invention also provides application of the lubricating oil base oil light stabilizer composition in improving the light stability of the lubricating oil base oil or the lubricating oil.
The above-mentioned light stabilizer composition for lubricant base oils of the present invention is generally added in an amount of 100-500ppm, for example 300ppm, in the lubricant base oil or the lubricant.
The invention also provides lubricating base oil or lubricating oil containing the lubricating base oil light stabilizer composition.
The lubricating oil of the present invention may be a mixture of a lubricating base oil and additives.
The invention discovers that the color stability of the base oil under the condition of visible light can be greatly improved by adding the lubricating oil additives into the base oil according to the proportion of 100-500ppm after optimized combination.
The composition of the invention can greatly improve the color stability of the base oil under the condition of visible light.
