Problems solved by technology

[0002] Compared with traditional rubber oil, naphthenic rubber oil has incomparable advantages, such as good compatibility with rubber, low volatility, good oxidation stability, non-toxic and pollution-free, healthy and safe, and meets the requirements of green environmental protection; However, a major defect that restrains the development of naphthenic rubber oils is poor photothermal stability. This problem is common in naphthenic rubber oils at home and abroad. At present, the main reason for the poor photothermal stability of naphthenic rubber oils is considered to be polycyclic Effects of Aromatics and Polar Compounds

Abstract

The invention discloses a composition for improving the anti-yellowing performance of naphthenic rubber oil, which is characterized in that 2 '-(2'-hydroxy-3 '-tert-butyl-5'-methylphenyl)-5-chlorobenzotriazole and 2, 6-di-tert-butyl-p-methylphenol are combined for use, and the combined use of the two can play a synergistic role, so that the anti-yellowing performance of the naphthenic rubber oil is improved, and the anti-yellowing performance of the naphthenic rubber oil is improved. And the naphthenic rubber oil does not change color under the condition of 7 days of illumination. Moreover, the anti-yellowing performance of the naphthenic rubber oil can be improved by adding a small amount of the composition into the naphthenic rubber oil, and the physicochemical properties of the naphthenic rubber oil cannot be influenced. The method is simple in technology and convenient to operate, and has good application and popularization value.

Description

technical field [0001] The present invention relates to compositions for improving the anti-yellowing properties of naphthenic rubber oils. The invention belongs to the technical field of rubber processing. Background technique [0002] Compared with traditional rubber oil, naphthenic rubber oil has incomparable advantages, such as good compatibility with rubber, low volatility, good oxidation stability, non-toxic and pollution-free, healthy and safe, and meets the requirements of green environmental protection; However, a major defect that restrains the development of naphthenic rubber oils is poor photothermal stability. This problem is common in naphthenic rubber oils at home and abroad. At present, the main reason for the poor photothermal stability of naphthenic rubber oils is considered to be polycyclic Effect of aromatic hydrocarbons and polar compounds. [0003] Under the excitation of UV light or heating, naphthenic rubber oil is subjected to O 2 attack, a chain-...
