摘要
采用偶联剂Si69对碳酸钙晶须进行表面处理,研究改性碳酸钙晶须对天然橡胶(NR)性能的影响。结果表明:偶联剂Si69能显著改善碳酸钙晶须的表面性能,提高碳酸钙晶须与NR基体的界面作用,碳酸钙晶须对NR起到明显的补强作用。当改性碳酸钙晶须用量为5份时,复合材料的综合性能最佳。改性碳酸钙晶须的加入使复合材料的热稳定性能得到了一定的提高。
The calcium carbonate whisker was modified by coupling agent Si69 ,and the influence of modified calcium carbonate whisker on the properties of NR compounds was investigated. The results showed that, the surface properties of calcium carbonate whisker were improved by coupling agent Si69,and the interface interaction between calcium carbonate whisker and NR matrix was improved, NR compounds were evidently reinforced by the modified calcium carbonate whisker. As the addition level of modified calcium carbonate whisker was 5 phr, the optimum comprehensive properties of calcium carbonate whisker/NR composites were obtained. The thermal stability of composites was improved when the modified calcium carbonate whisker was used.
