研究饱和度对氢化丁腈橡胶(HNBR)胶料物理性能、耐热空气老化性能和阻燃性能等的影响。结果表明,随着饱和度的提高,HNBR胶料正硫化时间延长,硫化胶拉断伸长率和拉断永久变形增大、耐热空气老化性能提高、储能模量和损耗因子减小、阻燃性能略有下降。
The influence of HNBR saturation degree on the physical properties, hot air aging resistance and flame retardance of HNBR compound was investigated. The results showed that as the HNBR saturation degree increased, the optimum cure time of the HNBR extended; the elongation at break,the tensile set at break and hot air aging resistance of HNBR vulcanizate improved, the storage modulus,tanδ and flame retardance decreased slightly.
