description The invention provides a modified quartz sand preparation method, and relates to the technical field of quartz sand processing. The method comprises scrubbing, ball milling, coating, drying and sintering processes. The ball milling process is adopted to ball-mill quartz sand into smaller granularities before modification, so that quartz sand powder is favorably dispersed better, the modification uniformity is further improved, and the modification quality is improved. The quartz sand powder is coated and modified with stirring at relatively high temperature, so that the coating probability of all the quartz sand is consistent. By the sintering process, volatile substances in a modifier can be removed, and meanwhile, a coating material is denser in structure and stronger in bonding strength with a quartz sand matrix, and is unlikely to be separated from the surface of the quartz sand, so that the modified quartz sand is stable in property. 本发明提供了种改性石英砂制备方法，涉及石英砂加工技术领域；包括擦洗、球磨、包覆、烘干和烧结工艺，改性前采用球磨工艺将石英砂球磨到更小粒度，有利
