Problems solved by technology
[0003] However, the following problems often exist in the processing and use of hydrorefined base oils: (1) hydrorefined base oils are prone to yellowing under the influence of high temperature, which affects the performance of downstream products; (2) hydrorefined base oils are also subject to light It is easy to turn yellow, filling it into the product will also affect the color of the product
[0004] Therefore, it is necessary to provide an anti-aging formula for hydrorefined base oils, which can solve the problem of thermal aging and discoloration as well as the problem of light discoloration

The present invention relates to a composition comprising hydrofined base oil and an anti-aging agent. The anti-aging agent comprises: (a) a hindered phenolic main antioxidant; (b) a phosphite ester auxiliary antioxidant; (c) an ultraviolet absorber; wherein the component (c) is preferably a benzotriazole ultraviolet light absorber or a benzophenone ultraviolet light absorber. The anti-aging agentis applied to the field of hydrofined base oil for the first time, has a good synergistic effect, can effectively solve the problems of thermal aging and illumination discoloration of hydrogenated base oil, and ensures the stability of the hydrofined base oil in the processing and using processes.
Description
technical field [0001] The invention belongs to the technical field of polymer material functional additives, in particular to an anti-aging composition for stabilizing hydrotreated base oil. Background technique [0002] Hydrorefined base oil is the base oil obtained by hydrotreating the base oil, which is widely used in transformer oil, rubber filling oil, adhesive filling oil, etc. [0003] However, the following problems often exist in the processing and use of hydrorefined base oils: (1) hydrorefined base oils are prone to yellowing under the influence of high temperature, which affects the performance of downstream products; (2) hydrorefined base oils are also subject to light It is easy to turn yellow, and filling it into the product will also affect the color of the product. At present, in the available patents and literatures, and in the manufacturers of hydrorefined base oils, there is no solution involving the use of antioxidants to protect the discoloration of h...
