采用湿法混炼工艺制备了二氧化硅分散粒径为100 nm的天然橡胶/二氧化硅复合材料胶母粒,结合传统干法混炼技术制备了二氧化硅总填充量为60份(质量)的微米/纳米共填充天然橡胶/二氧化硅复合材料。结果显示,湿法混炼过程中填充的小粒径二氧化硅仍然以小粒径分散,与橡胶分子链更倾向于形成紧密结合层。湿法混炼技术的使用提升了二氧化硅的分散性,复合材料的Payne效应更弱。与干法混炼技术并用制备的小粒径与大粒径二氧化硅比例为50/10时,填料形成了较宽的粒径分布,形成了适中的填料-橡胶结合强度,进一步提升了天然橡胶/二氧化硅复合材料的拉伸强度和扯断伸长率。
- Abstract:

Natural rubber/silica composite masterbatch with dispersed silica particle size of 100 nm was prepared by wet mixing process, and micron/nano co-filled natural rubber/silica composite with a total silica filling amount of 60 phr (mass) was prepared by traditional dry mixing process. The results showed that the silica with small particle size filled in the wet mixing process was still dispersed in its primitive size, and tended to form a tight bound rubber layer. The use of wet mixing process improved the dispersion of silica, and weakened the Payne effect of the composites. When the ratio of small to large silica particles prepared in combination with dry mixing process was 50/10, the wider particle size distribution of the filler was formed, and the silica-rubber binding strength was moderate, which further improved the tensile strength and elongation at break of natural rubber/silica composite.
