摘要:
采用巯基-烯点击法制备出1,2-聚丁二烯包覆的疏水性白炭黑(Silica-PBs)。红外光谱和X射线电子能谱分析表明,Silica-PBs表面被1,2-聚丁二烯所包覆,并且还有多余的乙烯基。将Silica-PBs与丁苯橡胶(SBR)共混制备的硫化胶相比于使用硅烷偶联剂改性制得的硫化胶具有更优异的综合性能。通过橡胶加工分析仪和电子显微镜分析均可以发现,Silica-PBs在SBR中具有更好的分散状态。Silica-PBs可以在填料与橡胶分子链之间形成一条“缓冲带”,为填料在橡胶分子链滑移时提供一定的缓冲作用。动态力学性能测试结果显示,Silica-PBs相比于传统白炭黑提高SBR/Silica-PBs复合材料的动态力学性能8%以上,可以作为一种理想的绿色轮胎用填料。
Abstract:
Hydrophobic silica coated with 1,2-polybutadiene (Silica-PBs) was prepared using thiol-ene click method. Infrared spectroscopy and X-ray photoelectron spectroscopy analysis confirmed that the surface of Silica-PBs was coated with 1,2-polybutadiene with excess vinyl groups. The vulca-nized rubber prepared by blending Silica-PBs with styrene-butadiene rubber (SBR) exhibited superior comprehensive properties compared to vulcanizate modified with silane coupling agents. Rubber processing analyzer and electron microscopy analysis demonstrated that Silica-PBs exhibited better dispersion in SBR, and could form "buffer zone" between the filler and rubber molecular chain, provi-ding a certain buffering effect when the filler slipped within the rubber molecular chain. Dynamic mechanical properties tests indicated that Silica-PBs improved the dynamic mechanical properties of SBR/Silica-PBs composites by more than 8% compared to traditional silica, and could be used as an ideal filler for green tires.
