[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The daily-use ceramics of the present invention use mullite, spodumene, and quartz as the matrix, and use the added yttrium-zinc compounding agent as an antibacterial functional agent. Nano-zinc oxide is formulated into cobalt nitrate and yttrium nitrate solutions, and then sintered and improved. Through the compounding enhancement among yttrium, zinc, and cobalt, the antibacterial stability of the product is optimized. At the same time, the added modifier filled with barium carbonate and the boron oxide additive are mutually coordinated, so that the antibacterial property, gloss property, and strength property of the obtained daily-use ceramics are balanced and coordinatedly improved, and the effects of the product's resistance to heat and cold and temperature stability are remarkable;

[0031] 2. The modifier filled with barium carbonate is made by mixing and ball-milling the barium carbonate filler and the modified strontium titanate solution. The barium carbonate filler is improved by ultrasonic mixing of sintering solution A and barium carbonate solution B. The sintered body, polyvinyl alcohol, and lanthanum nitrate solution in the sintering solution A are formulated and optimized. The lanthanum nitrate solution, as a rare earth solution, can enhance the coordination effect of the sintered body in the system, while polyvinyl alcohol cooperates with the lanthanum nitrate solution to enhance the penetration and interfacial property between the raw materials, so as to better mix and improve the sintering solution A and barium carbonate solution B;

[0032] 3. The talc, magnesium oxide, and cerium oxide in the sintered body are harmoniously optimized and improved. Talc is combined with magnesium oxide and cerium oxide to enhance the performance stability of the system. At the same time, the barium carbonate in the barium carbonate solution B is preheated, and then combined with nano-silica sol and sodium hexametaphosphate solution. Through the co-ordination of the raw materials, the barium carbonate filler prepared enhances the performance coordination and performance stability in the system;

[0033] 4. The modified strontium titanate solution is improved by stirring and mixing strontium titanate, zirconia, and modified sodium silicate agent. In the modified sodium silicate agent, sodium carboxymethylcellulose, sodium silicate solution, and bentonite are mutually optimized and coordinated. The lamellar bentonite is combined with raw materials such as sodium silicate solution, and then strontium titanate and zirconia are mixed to further strengthen and fill the system structure, so that the performance of the product is further improved;

[0034] 5. The boron oxide additive is prepared by proton-irradiating boron oxide to stimulate its active efficacy, and then adding a treatment liquid for improvement and optimization. The calcium sulfate whiskers in the treatment liquid are used as the matrix, and the nepheline structure is carried by the whisker structure. Then, silane coupling agent KH550 and sodium lignosulfonate solution are mixed. Through the co-blending and co-adjusting of raw materials, the prepared boron oxide additive has a better synergistic effect with the modifier filled with barium carbonate, and the performance of the product is further improved.
