研究高二聚体含量防老剂RD在胶料中的应用。结果表明,高二聚体含量防老剂RD在与防老剂4020并用时,适当减小防老剂RD的用量对胶料性能影响不大,尤其是防老剂S-RD减量60%时胶料仍具有较好的物理性能以及耐热氧老化和耐屈挠性能。
To study the application of high dimer antioxidant RD in rubber compound. The results showed that RD with high dimer content could effectively reduce the dosage of RD when the RD dosage was the same as that of the antioxidant 4020, especially when the dosage of the antioxidant S-RD was reduced by 60% Better physical properties and thermal aging resistance and flex resistance properties.
