Antibacterial glaze powder with photocatalytic activity and preparation process thereof
The invention relates to a divisional application with the application number of 202211297725.2, belongs to the technical field of ceramics, and particularly relates to antibacterial glaze powder with photocatalytic activity and a preparation process thereof. The antibacterial glaze powder with photocatalytic activity is prepared from, by weight, 25-35 parts of quartz, 10-20 parts of potassium feldspar, 3-5 parts of calcite and 5-8 parts of wollastonite. The coating is prepared from the following components in parts by weight: 2-3 parts of calcined talc, 1-3 parts of nano zinc oxide, 1-2 parts of cerium oxide, 1-2 parts of lanthanum oxide, 20-30 parts of a porous material, 5-8 parts of modified titanium dioxide, 5-10 parts of an antibacterial agent, 5-10 parts of a grinding aid, 1-2 parts of a deflocculating agent, 1-2 parts of an auxiliary agent and 3-8 parts of a coating agent. According to the antibacterial glaze powder with the photocatalytic activity, the silver-containing antibacterial agent and the nano zinc oxide can improve surface contact bacteria to kill bacteria, the modified titanium dioxide can improve the photocatalytic bacteria killing effect, and through combination of the silver-containing antibacterial agent, the nano zinc oxide and the modified titanium dioxide, the antibacterial effect of the antibacterial glaze powder is improved; multiple antibacterial layers are formed on the surface of a fired glaze layer, so that the antibacterial glaze has an excellent sterilizing effect.
本申请是申请号为202211297725.2的分案申请，本发明属于陶瓷技术领域，具体涉及一种具有光催化活性的抗菌釉粉及其制备工艺，其中一种具有光催化活性的抗菌釉粉，按重量份数计，由以下组分构成：石英25‑35份，钾长石10‑20份，方解石3‑5份，硅灰石5‑8份，烧滑石2‑3份，纳米氧化锌1‑3份，氧化铈1‑2份，氧化镧1‑2份，多孔材料20‑30份，改性二氧化钛5‑8份，抗菌剂5‑10份，助磨剂5‑10份，反絮凝剂1‑2份，助剂1‑2份，包膜剂3‑8份。本发明的一种具有光催化活性的抗菌釉粉，含银的抗菌剂、纳米氧化锌能够提高表面接触细菌进行杀灭，改性二氧化钛能够提高光催化杀灭细菌的效果，通过含银的抗菌剂、纳米氧化锌和改性二氧化钛的结合，在烧制的釉层表面形成多重的抗菌层，具备优异的杀菌效果。
