Electroceramic composite glaze and glazing process thereof
The invention discloses an electric porcelain composite glaze and a glazing process thereof, and relates to the technical field of electric porcelain glaze preparation, the composite glaze comprises the following raw materials by weight: 10-30 parts of nano silica, 20-50 parts of micron alumina, 2-5 parts of nano yttrium oxide, 1-10 parts of glass fiber, 10-30 parts of kaolin, 1-3 parts of lithium oxide, and 10-30 parts of sodium carboxymethyl cellulose. According to the preparation method disclosed by the invention, the micron aluminum oxide and the nano silicon dioxide are added to form mixed particles with micro-nano structures, and the micro-nano bulges are obtained after glazing and firing and have very excellent hydrophobic performance. According to the preparation method, aluminum oxide is added, yttrium oxide is added and reacts with aluminum oxide during firing to produce a YAG phase, an Al-O bond of the phase structure is very short, the chemical property is very stable, and the mechanical strength is greatly improved, the surface of a porcelain piece is coated with a silane coupling agent at least twice, so that the binding force between the glaze surface and the surface of the porcelain piece is greatly increased, and the service life of the porcelain piece is prolonged. The mechanical strength is improved.
本发明公开了一种电瓷复合釉料及其上釉工艺，涉及电瓷釉料制备技术领域，复合釉料包括以下重量份数的原料：10‑30份纳米二氧化硅、20‑50份微米氧化铝，2‑5份纳米氧化钇、1‑10份玻璃纤维、10‑30份高岭土、1‑3份氧化锂、和10‑30份羧甲基纤维素钠。本发明通过加入微米氧化铝和纳米二氧化硅，形成微纳结构的混合颗粒，在上釉烧成后得到微纳凸起，具有非常优异的疏水性能。再者加入氧化钇，其与氧化铝在烧成中反应，生产YAG相，这种相结构的Al‑O键非常短，化学性质非常稳定，使其机械强度大大提升，本发明还通过在瓷件表面进行至少两次的涂覆硅烷偶联剂，使得其釉面和瓷件表面的结合力大大增加，提高其机械强度。
