Common high-temperature cables are wrapped with a layer of “rubber protective layer”. When such a protective layer is destroyed, the inside of the high-temperature cable will be damaged and cannot be used anymore, so the manufacturer will prevent the outer rubber protective layer from aging. Treatment, this process involves the anti-aging agent.
Due to the different characteristics of each anti-aging agent, and the aging properties of different rubber formulations are different. Therefore, the most effective anti-aging agent for a certain rubber material may be ineffective or even harmful to another rubber material. Therefore, the selection of anti-aging agents must be considered in accordance with the aging properties of various rubber materials, anti-aging requirements and the characteristics of various anti-aging agents.
2. Use together
When an anti-aging agent is difficult to meet the requirements, two or more anti-aging agents should be used together to create a coordinated effect to ensure anti-aging effects.
Some anti-aging agents have a coloring effect and contamination on the rubber. In general, phenolic antioxidants have poor protection but are not contaminated or contaminated. The amine anti-aging agent with higher protection effect will cause rubber pollution and serious discoloration. These contradictions should be considered when they are selected.
The amount of antioxidant should not exceed the solubility in rubber to prevent blooming and contaminate the surface quality of the rubber.
Amine anti-aging agents have an adverse effect on rubber scorch; phenolic anti-aging agents can delay vulcanization and should be taken care of when selecting. The treatment of the rubber protective layer by the anti-aging agent needs to be taken seriously as an important protection measure for the high-temperature cable. With solid protection, the service life of the high-temperature cable can be further ensured, and the erosion of various hazards can be resisted.
