AI Technical Summary
Technical Problem
The wear resistance and flexural strength of existing ceramic tiles are insufficient, resulting in insufficient mechanical strength, limiting their use.
Method used
By mixing potassium feldspar, sodium feldspar, kaolin, serpentine, dolomite, nanozirconia, nanoceria, nanomolybdenum disulfide, silicon carbide fiber, polyethylene glycol, fullerene trifluoromethyl derivative and solvent, a uniformly dispersed slurry was obtained, spray granulation, press molding and sintering, to produce flexural and wear-resistant ceramics.
Benefits of technology
The prepared flexural and wear-resistant ceramics have high flexural strength (can exceed 70MPa) and good wear resistance (grinding pit length does not exceed 8.5mm), which significantly improves the mechanical strength of the ceramics.

Abstract
The invention belongs to the technical field of ceramics, and discloses a preparation method of fracture-resistant and wear-resistant ceramics. The preparation method comprises the following steps: weighing the raw materials in parts by weight; the preparation method comprises the following steps: mixing 40 parts of potassium feldspar, 10 to 25 parts of albite, 1 to 10 parts of kaolin, 1 to 10 parts of serpentine, 5 to 25 parts of dolomite, 2 to 9 parts of nano zirconium oxide, 0.1 to 1 part of nano cerium oxide, 0.1 to 1 part of nano molybdenum disulfide, 0.1 to 0.8 part of silicon carbide fiber, 0.5 to 2.5 parts of polyethylene glycol, 0.1 to 0.6 part of fullerene trifluoromethyl derivative, 0.1 to 3 parts of sodium dodecyl sulfate, 0.1 to 2 parts of sodium tripolyphosphate and 10 to 60 parts of solvent to obtain slurry; and carrying out spray granulation to obtain a blank, carrying out compression molding to obtain a green body, and sintering to obtain the fracture-resistant and wear-resistant ceramic. The breaking strength of the breaking-resistant and wear-resistant ceramic can exceed 70 MPa, and the length of a grinding pit does not exceed 8.5 mm.
