DETAILED DESCRIPTION - High wear-resistant ceramic comprises 10-18 pts. wt. quartz sand powder, 4-7 pts. wt. silicon carbide powder, 0.5-4.0 pts. wt. alumina powder, 15-22 pts. wt. modified epoxy resin, 3-8 pts. wt. magnesium oxide powder, 1-4 pts. wt. calcium oxide powder, 12-25 pts. wt. silicate, 0.2-1.8 pts. wt. graphene, 0.5-20 pts. wt. vegetable oil, and 30-52 pts. wt. bentonite. The modified epoxy resin is prepared by mixing nitrile butyl rubber and epoxy resin at mass ratio of (1-3):(5-9); heating mixture at 100-160 degrees C while stirring at 1200-1800 revolutions per minute for 15-30 minutes; and adding mixture with phenol and formaldehyde at ratio of 1:(1.5-3) for 30-75 minutes. An INDEPENDENT CLAIM is included for preparation of high wear-resistant ceramic by putting quartz sand powder, modified epoxy resin, alumina powder and silicate into container; pretreating at 420-560 degrees C for 3-8 minutes; grinding and sieving through 50-80 meshes; adding graphene and stirring at 150-600 revolutions per minute for 10-20 minutes at room temperature to obtain first mixture; putting silicon carbide powder, magnesium oxide powder, calcium oxide powder and bentonite into ball mill; ball milling at 35-50 degrees C for 2-5 hours until powder is mixed uniformly; passing powder through 80-120 meshes sieve to obtain second mixture; adding vegetable oil to second mixture; treating mixture at 120-155 degrees C for 10-20 minutes; cooling at 65-90 degrees C while stirring at 1500-1800 revolutions per minute for 30-60 minutes to obtain third mixture; uniformly mixing first mixture, third mixture and graphene; pressing mixture at 800-1200 MPa for 1-3 minutes to obtain green body; sintering green body at 650-820 degrees C for 1.5-4.0 hours under protection of nitrogen or argon; and cooling at room temperature to produce finished product.
