| 中文摘要: |
| 以硅藻土和白炭黑作为复合填料填充天然橡胶（NR），研究硅藻土用量对硅藻土/白炭黑复合填料补强天然橡胶（DCNR）复合材料性能的影响。结果表明：随着硅藻土用量的增大，DCNR复合材料的t10和t90先增大后减小；硅藻土用量较小时，可提高DCNR复合材料的邵尔A型硬度；硅藻土用量过大，易产生明显的团聚，从而降低硅藻土/白炭黑复合填料对NR基体的补强效果，使得DCNR复合材料的综合物理性能下降。 |
| 英文摘要: |
| Natural rubber（NR） was filled with diatomite and silica as composite fillers，and the effect of diatomite amount on properties of composite reinforced with diatomite/silica composite filled NR（DCNR） was studied.The results showed that，as the dosage of diatomite increased，the t10 and t90 of DCNR composites increased at first and then decreased.When the amount of diatomite was small，the Shore A hardness of DCNR composites could be improved.If the amount of diatomite was too large，it was easy to produce obvious agglomeration，thus reduced the reinforcement effect of diatomite/silica composite filler on NR matrix and the comprehensive physical properties of DCNR composites were decreased. |
