Properties Of Common Rubber Antiaging Agents

A、Amine anti-aging agents and amine anti-aging agents are mainly used to inhibit the aging of hot oxygen, ozone, fatigue and heavy metal ion catalytic oxidation. The downside is polluting, according to the structure can be further divided into A, phenyl naphthylamine classes, such as prevent or prevent A, antiager J, or D, PBNA is the oldest of the stabilizer, mainly used for inhibiting hot oxygen aging and fatigue, aging because of toxicity, at present this kind of age is rarely used in foreign countries.

B、Ketone amine stabilizer and gives our class diene rubber good hot oxygen aging resistance, in some cases gives good flexible crack resistance, but few are inhibiting the catalytic oxidation of metal ions and ozone aging function. The most commonly used variety is BLE. Anti - aging agent RD. Anti - aging agent AW not only has the function of anti - oxygen agent, but also often used as anti - odor oxygen agent.


C、Diphenylamine derivatives, which have the effect of inhibiting the aging of hot oxygen, are equal to or less than dihydroquinoline polymers, and when used as antioxidants, are equivalent to the anti-aging agent DD. However, the protective effect on fatigue aging is lower than that of the latter.


D、P-phenylenediamine derivatives, this kind of anti-aging agent is currently widely used in the rubber industry. They can inhibit the ozone aging of rubber products, fatigue aging, thermal oxygen aging and metal ion catalytic oxidation. Dialkyl p-benzene Diane (e.g. UOP788). This kind of material has the special anti-static ozone aging performance, especially when there is no paraffin, and has the good anti-aging effect of heat and oxygen. But there is a tendency to promote burning.
