Application:

In order to improve the protective effect, two anti-aging agents with different action mechanisms are often used in combination in practice, or two anti-aging agents of the same protective mechanism are used together, or a group acting on different molecules on the same molecule is simultaneously selected. The presence of anti-aging agents can also achieve synergistic protective effects. However, in some cases, when two protective substances are used together, the protective effect is reduced. Therefore, when the protective agent is used together, it must be carefully analyzed.

After use.

Counteracting effect

The antagonistic effect means that when two or more antioxidants are used in combination, the protective effect produced is less than the sum of the effects when they are used alone. This should be prevented in actual use.

Studies have shown that when an acidic preservative is used in combination with an alkaline anti-aging agent, an antagonistic effect is produced because the two will produce a salt-like complex. In addition, the usual chain-breaking antioxidants also have an antagonistic effect with certain sulfides, especially polysulfides. In the vulcanized natural rubber containing 1% of 4010NA, the addition of polysulfide increases the oxidation rate, which is also an antagonistic effect. In the purification of natural rubber containing peroxides containing aromatic amines or hindered phenols,

A similar phenomenon was observed in the trisulfide. The generation of the antagonistic effect is closely related to the structure of the sulfide. For example, the di-alkene sulfide has a significant antagonistic effect with the antioxidant, while the di-n-butyl sulfide and the tri-n-hexyl trisulfide have no antagonistic effect. Generally, the effect of monosulfide is smaller than that of polysulfide. Carbon black has both the effect of inhibiting oxidation and the role of oxidation in rubber. A reduction in the inhibitory effect of carbon black in the presence of a chain-breaking antioxidant or a decrease in the protective effectiveness of the antioxidant in the presence of carbon black clearly indicates an antagonistic effect between them.
