| 摘 要： | 研究了炭黑Ｎ６６０、Ｎ６３０、Ｎ７６２、天然气半补强炭黑及喷雾炭黑对ＮＢＲ／均聚氯醚橡胶（ＣＨＲ）并用胶性能的影响。试验结果表明，这些炭黑在ＮＢＲ／ＣＨＲ并用胶中的用量达到８０份时，并用胶的加工性能仍较好。随着炭黑用量的增大，ＮＢＲ／ＣＨＲ并用胶的耐四氯化碳性能提高；压缩永久变形、压缩温升及硬度增大；扯断伸长率和回弹值下降；而拉伸强度则是先升高，当炭黑用量达到６０份时即下降；撕裂强度也是先升高，而后在不同用量处出现下降趋势。

| Abstract: | The influence of some carbon blacks,such as N660,N630,N762,semi reinforcing gas black and jet black and their loading level on the properties of NBR/CHR blend was investigated.The results showed that the processibility of blend was satisfactory with the loading level of said carbon blacks up to 80 phr;the carbon tetrachloride resistance,the compression set and heat build up and the hardness of the blend increased,but the elongation at break and the relience decreased as the loading level of blacks increased;the tensile strength didn't decrease untill the loading level of blacks increased up to 60 phr;the tear strength didn't decrease either untill the loading level of blacks increased to different points depending upon the types of blacks. |
