Antibacterial material, antibacterial agent, antibacterial ceramic tableware and preparation method thereof
The invention discloses an antibacterial material, an antibacterial agent, antibacterial ceramic tableware and a preparation method of the antibacterial ceramic tableware. The preparation method comprises the following steps: mixing 5%-10% of zinc salt, 0.05%-0.1% of silver salt and 1%-3% of polyvinylpyrrolidone in a solvent, and adjusting the pH value of the mixed solution to 9-11; and annealingthe mixed solution at 400-700 DEG C for 1-4 hours to obtain the antibacterial material; ultrasonically dispersing the antibacterial material in a solvent; then, mixing the antibacterial agent with a hydrophobic modifier with the content of 4-17wt%, and carrying out suction filtration and drying to obtain the antibacterial agent; mixing the antibacterial agent with glaze to obtain glaze slip, and uniformly spraying the glaze slip to the surface of the ceramic tableware blank to form a glaze layer; and sintering the ceramic tableware green body to obtain the antibacterial ceramic tableware. According to the antibacterial material disclosed by the invention, the antibacterial agent can be coated on the surface of tableware to form a hydrophobic layer, and the antibacterial efficiency of the antibacterial ceramic tableware is improved.
本发明公开了一种抗菌材料、抗菌剂和抗菌陶瓷餐具及其制备方法。将含量为5％～10％的锌盐、含量为0.05～0.1％的银盐和1％～3％的聚乙烯基吡咯烷酮在溶剂中混合，并调节所述混合溶液的pH值至9～11；将混合溶液在400～700℃下退火1～4小时，即得抗菌材料；将抗菌材料在溶剂中超声分散；再将其与含量为4～17wt％的疏水改性剂混合、抽滤并烘干，即得抗菌剂；将抗菌剂与釉料混合，得到釉浆，再将釉浆均匀淋涂至陶瓷餐具坯体的表面形成釉层；将所述陶瓷餐具坯体烧结，即得抗菌陶瓷餐具。本发明的抗菌材料、抗菌剂可涂覆于餐具表面形成疏水层，并提高了抗菌陶瓷餐具的抗菌效率。
