| 摘 要： | 研究了填料－橡胶的相互作用。发现N330－NR间的相互作用。n－SiO2（粒径：15nm）／KH－846－NR间的相互作用，都是化学作用占优势（＞80％），化学作用对补强的贡献率都大于90％；无偶联剂KH－846时，n－SiO2和SiO2（粒径：15．8nm）与NR都无化学作用，只有物理交联，由于隔离作用，都降低硫化体系与橡胶相互作用的化学交联密度，但n-SiO2的物理交联密度是SiO2的2．6倍，对补强的贡献是SiO2的1．9倍，也是n-SiO2／KH－846体系的61％。

| Abstract: | The filler rubber interaction was studied in this paper. It was found that the chemical imteraction of N330 NR,and n SiO 2/KH 846 NR all predominated over their physical interaction(>80%), the reinforcement ratio was more than 90%;As couplant did not occur ,n SiO 2, SiO 2 adn NR hadn't chemical interaction, only had physical interaction; The crosslinking density of vulcanization system and rubber were decreased because of barrier interaction. But the physical crosslinking density of n SiO 2 and NR was 2.6 time of SiO 2 and NR, the reinforcement was 1.9 time of SiO 2 and NR, was 61% of n SiO 2/KH 846. |
