| Abstract: |
| The blend of NR and NBR have excellent physical properties and good oil resistant performance . The Carbon black/NR composites’ physical properties is better than Carbon black/NR/NBR composites , so add calcium carbonate whisker into the composites to improving the physical properties . In this article ,the calcium carbonate whisker was modified by coupling agent titanate , and the influence of modified calcium carbonate whisker on the propertier of Carbon black/NR/NBR composites was investigated .The results showed that ,the surface properties of calcium carbonate whisker were improved by titanate , and the compatibility between calcium carbonate whisker and Carbon black/NR/NBR composites was improved .As the addition level of modified calcium carbonate whisker was 4phr ,the optimum comprehensive propertied of calcium carbonate whisker/ carbon black/NR/NBR composites were obtained and it improved the effect of Payne . |
