| 中文摘要: |
| 采用溶液聚合法将硅烷偶联剂KH-570接枝到低相对分子质量的聚丁二烯液体橡胶（LMPB）分子长链中，合成了新型大分子表面处理剂LMPB-g-KH-570，用其对纳米氮化硅进行表面改性，制备改性纳米氮化硅/丙烯酸酯橡胶（ACM）复合材料，并对其结构和性能进行研究。结果表明：LMPB-g-KH-570与纳米氮化硅发生了化学键合；在复合材料中加入适量LMPB-g-KH-570，可以改善纳米氮化硅在复合材料中的分散性，提高复合材料的物理性能。 |
| 英文摘要: |
| A new macromolecular coupling agent LMPB-g-KH-570 was synthesized by grafting silane coupling agent KH-570 onto low molecular weight liquid polybutadiene rubber（LMPB） via solution polymerization.The surface of nano-silicon nitride was modified by LMPB-g-KH-570，and the modified nano-silicon nitride/ACM composite was prepared.The structure and properties of the composite were investigated.The results showed that，LMPB-g-KH-570 was chemically bonded with nano-silicon nitride；by adding proper level of LMPB-g-KH-570，the dispersion of nano-silicon nitride in the composite and the physical properties of the composite were improved. |
