摘要

采用胶乳复配法制备了羧基化丁苯橡胶(XSBR)与天然橡胶(NR)填充聚苯乙烯包封纳米二氧化硅(ps - nsio2)的共混橡胶。采用原位差异微乳液聚合法制备的PS-nSiO2作为填料，在3 phr的条件下，以不同的XSBR/NR共混比(70/30、50/50和30/70)作为填料。这种纳米复合乳胶被浇铸成薄片，放在玻璃模具上，然后在烤箱中固化。测试了试样的拉伸性能、动态力学性能和热稳定性。橡胶共混物的抗拉强度和断裂伸长率随NR含量的增加而增加，但模量下降。此外，PS-nSiO2的加入改善了共混体系的拉伸性能、动态力学性能和热稳定性。

XSBR/NR Rubber Blends Filled with Polystyrene-Encapsulated Nanosilica Prepared by in situ Differential Microemulsion Polymerization

Rubber blends of caboxylated styrene butadiene rubber (XSBR) and natural rubber (NR) filled with polystyrene-encapsulated nanosilica (PS-nSiO 2) were prepared by latex compounding. The PS-nSiO2 synthesized by in situ differential microemulsion polymerization was used at 3 phr as the filler in three different XSBR/NR blend ratios (70/30, 50/50, and 30/70). The nanocomposite latex was cast into sheets on glass molds and cured in an oven. The specimens were examined for their tensile properties, dynamic mechanical properties, and thermal stability. The tensile strength and elongation at break were found to increase with increasing levels of NR in the rubber blends, but the modulus decreased. Moreover, the tensile properties, dynamic mechanical properties, and thermal stability were all improved by the addition of PS-nSiO2 within the blend systems.
