| 中文摘要: |
| 试验研究3种硬脂酸系表面改性剂对碳酸钙晶须/天然橡胶（NR）复合材料物理性能和热稳定性的影响。结果表明：经表面改性剂处理的碳酸钙晶须表面性能提高，与NR界面作用增强；改性碳酸钙晶须/NR复合材料的定伸应力、拉伸强度和撕裂强度均比未改性时有所增大；硬脂酸改性的复合材料综合物理性能较优，硬脂酸或硬脂酸钠改性的复合材料热稳定性提高。 |
| 英文摘要: |
| The effects of three kinds of stearic acid surface modifiers on the physical properties and thermal stability of calcium carbonate whisker/NR composite were experimentally investigated.The results showed that，the surface property of calcium carbonate whisker was improved after surface treatment， and the interfacial interaction with NR was strengthened.Compared with the unmodified calcium carbonate whisker/NR composite，the modulus， tensile strength and tear strength of the composite with modified calcium carbonate whisker increased.The comprehensive physical properties of the composite by using stearic acid as the surface modifier were better，and the thermal stability of the composite by using stearic acid or sodium stearate was improved. |
