| 摘 要： | 本文探讨了选用共聚酰胺ＰＡ（ＮＴ－１３０），采用低温混炼工艺所制备的丁腈橡胶／共聚酰胺共混弹性材料的结构及性能。结果表明：该共混材料的相态为两相分离结构；合适的共混比为８０／２０—６０／４０，此时，材料具有高强、高硬度及较高的伸长率和优良的耐摩擦性、耐低温性、耐热油老化性；十腈橡胶与共聚酰胺ＰＡ（ＮＴ－１３０）最适宜的共混温度低于ＰＡ（ＮＴ－１３０）熔点２０－３０℃。

| Abstract: | The structure and Performance of nitrile rubber/polyamide (NBR/PA) blending elastic material preP8red by low-t.emperature blend were studied in this paper. The results show that thephase morphology of this material is the phsse seporation structure. When NBR/PA mass ratiosare 80/ 20 - 60/ 40, the material posses high tensile strength, hardness and elongation atbreak. and it has good friction property, low temperature resistance and hot oil resistance. Theappropriate blending temperature of NBR/PA is about 20℃ below the melting point of PA. |
