Antibacterial porcelain tooth material and preparation method thereof

The invention discloses an antibacterial porcelain tooth material. The antibacterial porcelain tooth material is prepared from the following raw material components in parts by weight: 3 to 6 parts oflithium carbonate, 3 to 5 parts of potassium feldspar, 3 to 5 parts of albite, 1 to 2 parts of tin oxide, 2 to 3 parts of strontium oxide, 1 to 2 parts of nano titanium dioxide, 5 to 10 parts of zirconium dioxide, 6 to 8 parts of polyurethane, 5 to 8 parts of polymethyl acrylate, 2 to 3 parts of polyethylene glycol, 2 to 4 parts of glycerol, 25 to 40 parts of absolute ethyl alcohol, 0.01 to 0.02part of nano-silver powder, 1 to 2 parts of compound plant essential oil and 80 to 150 parts of deionized water. According to the antibacterial porcelain tooth material disclosed by the invention, themechanical properties of porcelain teeth are effectively improved by compounding the potassium feldspar with the albite; by specially doping the nano titanium dioxide, the nano-silver powder and thecompound plant essential oil
