| 中文摘要: |
| 分别采用白炭黑或埃洛石填充4种橡胶树品系（72059，PR107,73397和RRIM600）天然橡胶（NR）以制备复合材料，并研究复合材料的各项性能。结果表明：白炭黑或埃洛石填充NR复合材料的硫化特性受橡胶树品系的影响较小；两种填料填充的RRIM600复合材料均表现出最大的溶胀平衡交联密度和最优的物理性能，且50～70 ℃范围内的损耗因子最小，表明RRIM600复合材料的滞后损失最小，RRIM600满足低滚动阻力轮胎的用胶要求，而72059复合材料的相应性能较差；白炭黑填充72059复合材料的热稳定性最优，埃洛石填充各橡胶树品系NR复合材料的热稳定性差异不明显；PR107复合材料和73397复合材料的综合性能居中。 |
| 英文摘要: |
| The natural rubber（NR） composites of four rubber tree strains（72059，PR107，73397 and RRIM600） filled with silica or halloysite were prepared，and their properties were studied. The results showed that the vulcanization properties of NR composites filled with silica or halloysite were less affected by the rubber tree strain. The RRIM600 composites filled with silica or halloysite exhibited the largest swelling equilibrium crosslink density，the best physical properties and the smallest loss factor in the range of 50～70 ℃，which indicated that the hysteresis loss of RRIM600 composites was the smallest and RRIM600 met the requirements of low rolling resistance tires，and the corresponding properties of 72059 composites were poor，but the thermal stability of 72059 composites filled with silica was the best. The difference among the thermal stability of NR composites of various rubber tree strains filled with halloysite was not obvious. The comprehensive properties of PR107 composites and 73397 composites were in the middle. |
