Abstract
The application provides an antioxidant, which has the following structure: wherein R1 is selected from -NH- or -S-; and R2 is selected from -COO- or -S-. The high-voltage cable insulating material with the new antioxidant can obviously improve the precipitation phenomenon of the antioxidant of the traditional cable material without affecting the heat aging property and the anti-burning property, and effectively solves the "blooming" problem.
