| 中文摘要: |
| 采用甲基丙烯酸甲酯(MMA)-丙烯酸丁酯(BA)-甲基丙烯酸环氧丙酯(GMA)三元共聚物对纳米氮化钛进行表面改性，制备改性纳米氮化钛/丙烯酸酯橡胶（ACM）复合材料，并研究改性纳米氮化钛用量对复合材料性能的影响。结果表明，随着改性纳米氮化钛用量的增大，复合材料的物理性能、耐热空气老化性能、耐油性能和耐磨性能先提高后下降；改性纳米氮化钛对复合材料的高温稳定性影响不大，但提高了动态力学性能；当改性纳米氮化钛的用量为0.6～1份时，复合材料的综合性能较好。 |
| 英文摘要: |
| The surface of nano-titanium nitride was modified by methyl methacrylate(MMA)-butyl acrylate(BA)-glycidyl methacrylate (GMA) terpolymer，and the modified nano-titanium nitride/acrylate rubber(ACM) composite was prepared，and then the effects of the addition level of modified nano-titanium nitride on the properties of the composite were investigated. The results showed that as the addition level of modified nano-titanium nitride increased，the physical properties，hot air aging properties，oil resistance and wear resistance increased first and then decreased；the modified nano-titanium nitride had little effect on the high temperature stability of the composite，but could improve the dynamic mechanical properties；when the addition level of modified nano-titanium nitride was 0.6 ～ 1 phr，the composite possessed better comprehensive properties. |
