Catalyst carrier, supported catalyst as well as preparation method and application of supported catalyst

The invention provides a catalyst carrier. The structure of the catalyst carrier is shown in the following formula (1). Wherein the carrier is independently selected from one or more of silicon dioxide, magnesium oxide, titanium dioxide, zinc oxide, aluminum oxide, magnesium chloride, glass fibers, graphene, expanded graphite, ammonium polyphosphate, carbon black, carbon nanotubes, polyaniline, polypyrrole, polythiophene and nylon. On the other hand, the invention provides a supported catalyst. The supported catalyst prepared from the catalyst carrier can catalyze ethylene polymerization in situ to obtain a high-molecular-weight polyvinyl composite material. In the polymerization process, scaling of a reaction kettle can be effectively avoided, a granular polymer is obtained, and the carrier and the polymer are good in compatibility and uniform in dispersion. # imgabs0 # 本发明提出了一种催化剂载体，其结构如下式(1)所示。其中，载体独立地选自二氧化硅、氧化镁、二氧化钛、氧化锌、三氧化二铝、氯化镁、玻璃纤维、石墨烯、膨胀石墨、聚磷酸铵、碳黑、碳纳米管、聚苯胺、聚吡咯、聚噻吩、尼龙中的一种或多种。本发明的另一方面提出了一种负载型催化剂，利用上述催化剂
