Abrasive for grinding artificial quartzite sheet material and preparation method thereof

The invention discloses abrasive for grinding an artificial quartzite sheet material and a preparation method thereof. The abrasive is prepared from the following raw materials: 1% graphene modified epoxy resin, silicon carbide powder, white corundum micropowder, short carbon fibers, high-carbon ferro-chrome powder, graphite grease, a curing agent and wetting dispersant, and has high abrasion resistance. Compared with an existing quartzite abrasive, the abrasive has the advantages that the friction coefficient is reduced by 50 percent, the grinding efficiency is improved by 50 percent, the abrasion speed in the same area is reduced by 40 percent, and the glossiness after grinding is improved by 3-8 degrees, and can be used for solving the problems of low grinding efficiency, easy loss and the like of the existing quartzite abrasive, thus having a good application value.
