Preparation method of low-cost low-expansion ceramic zirconium-free glaze
The invention discloses a low-cost low-expansion ceramic zirconium-free glaze preparation method, which relates to the technical field of ceramic glazes, and comprises: carrying out mixing ball milling on modified mica powder, quartz, spodumene, celestite and wollastonite, adding a half weight of asbestos wool, and uniformly mixing to obtain a first mixture; mixing and subjecting sepiolite powder, bentonite, boron nitride, barium carbonate and zinc oxide to ball milling, then adding half of the weight of modified lignin fiber, and uniformly mixing to obtain a second mixture; adding sodium hexametaphosphate, plant ash and residual asbestos wool into the first mixture and the second mixture, and uniformly mixing to obtain a third mixture; and adding the modified nano calcium carbonate and the remaining modified lignin fibers into the third mixture, and uniformly mixing to obtain the glaze. The preparation method has the beneficial effects that the viscosity and expansion coefficient of the glaze can be reduced, the bonding strength of the glaze and the ceramic body is improved, and cracks are unlikely to occur.
本发明公开了一种低成本低膨胀陶瓷无锆釉制备方法，涉及陶瓷釉料技术领域，包括：将改性云母粉、石英、锂辉石、天青石和硅灰石混合球磨，再加入二分之一重量的石棉绒混合均匀，得到第一混合物；将海泡石粉、膨润土、氮化硼、碳酸钡和氧化锌混合球磨，再加入二分之一重量的改性木质素纤维，混合均匀得到第二混合物；将第一混合物和第二混合物，再加入六偏磷酸钠、草木灰和剩余的石棉绒，混合均匀得到第三混合物；往第三混合物中加入改性纳米碳酸钙和剩余的改性木质素纤维，混合均匀得到釉料。本发明的有益效果是能够降低釉料的粘度和膨胀系数，提高釉料与陶瓷坯体的结合强度，不易出现裂纹。
