采用机械力化学法制备功能化聚丙烯超细粉末。采用自行设计的磨盘式机械力化学反应器对聚丙烯（PP）进行磨盘式粉碎，并在粉碎过程中将无机过氧化物溶液喷涂到PP粉体表面，利用球磨产生的机械力化学效应实现PP的快速功能化。电子能谱化学分析（ESCA）结果表明，用该方法制备的PP超细粉体可获得氧含量（O/C）大于0.1的超细粉体。讨论了无机过氧化物溶液浓度、喷涂量、球磨温度等因素对功能化程度的影响。此外，还研究了PP在此过程中的降解情况。
In this paper, a mechanochemical method was established to prepare functionalized ultra-fine polypropylene powder. Through pan-milling by a self-designed pan-type mechanochemical reactor, polypropylene (PP) was finely pulverized, during the process, Inorganic peroxide solution was sprayed onto the PP powder surface to realize its rapid functionalization taking advantages of the mechanochemical effects caused by milling. Analysis results of electron spectroscopic chemical analysis (ESCA) show the PP ultra-fine powder prepared by this method can obtain over 0.1 oxygen content (O/C). Some factors influencing functionalization degree, including concentration, spraying amount of Inorganic peroxide solution and milling temperature, were discussed. Besides, the degradation of PP during this process was investigated.
