摘要
本文研究了不同防老剂在硅橡胶/EVA共混物中的抗氧的作用,利用热分析技术分析了共混物的抗氧化能力。研究结果表明,防老剂可以有效抑制硅橡胶/EVA共混物的热氧化过程,可使共混物的耐热氧老化性能从100℃提高到170℃以上,短期可达180℃～200℃。
The thermal and oxidative tesistances of silicone rubber/EVA blends were significantly improved by the addition of suitable antioxidants. The result was shown that RD was the most efficient antidegradant of preventing EVA of blends from thermal and oxidative, degradation, The differential scanning calorimetry and thermal gravimetric analysis were used to describe the oxidative resistance of antioxidants rapidly.
