| 中文摘要: |
| NBR的溴化酚醛树脂硫化体系和聚丙烯酸酯橡胶（ACM）的硫化剂AB-S会相互干扰，产生硫化不相容性，导致NBR，ACM和NBR/ACM共混物性能下降。通过在NBR/ACM共混物中加入溴化酚醛树脂对NBR进行动态硫化，然后加入AB-S对ACM进行静态硫化的方法，能够较好地解决这两种不相容硫化体系的相容性问题，所得到的共混物表现出良好的物理性能，且优于相应的静态硫化共混物。同时考察了NBR/ACM的共混比对共混物性能的影响。 |
| 英文摘要: |
| The vulcanizing agent brominated resin for NBR and the vulcanizing agent AB-S for ACM will interfere with each other during vulcanization resulting in the worsened properties of their blend. An effective procedure to improve the compatibility between the two vulcanizing systems is that at first the NBR/ACM blend is dynamically vulcanized with brominated phenolic resin and then statically vulcanized with AB-S. The vulcanizate shows good physical properties which are better than those of the blend vulcanized statically. The effct of blending ratio of NBR/ACM on their physical properties is investigated. |
