Common high-temperature cables are wrapped with a "rubber protective layer". When such a protective layer is damaged, the interior of the high-temperature cable will be damaged, making it impossible to continue to use it. Therefore, manufacturers will protect the outer rubber protective layer from aging. Anti-aging agent is involved in this process.

1. Aging performance

Due to the different characteristics of each antioxidant, and the aging properties of different rubber formulations are different. Therefore, the most effective antioxidant for one rubber may be ineffective or even harmful to another. Therefore, the selection of antioxidants must be considered and reasonably selected according to the aging properties of various rubber materials, anti-aging requirements and the characteristics of various antioxidants.

2. Combined use

When one anti-aging agent is difficult to meet the requirements, two or more anti-aging agents should be used together to make them have a coordinated effect and ensure the anti-aging effect.

3. Pollution

Some antioxidants have a coloring effect and contamination on the rubber. Generally speaking, phenolic antioxidants have poor protective effect, but do not contaminate or contaminate very little. The amine antioxidants with higher protective effect will contaminate the rubber and cause serious discoloration. These contradictions should be considered in the selection process.

4. Dosage

The amount of antioxidant should not exceed the solubility in rubber to prevent frost spray and contaminate the surface quality of rubber.

5. Function

Amine antioxidants have adverse effects on rubber scorch; phenolic antioxidants can delay vulcanization and should be paid attention to when selecting them. As an important protective measure for high-temperature cables, the treatment of the rubber protective layer by antioxidants requires everyone to pay attention. Only with solid protection can the service life of high-temperature cables be further ensured and the erosion of various hazards can be resisted.
