Lead-free iron-based metallic glaze and preparation method thereof
The invention discloses a lead-free iron-based metallic glaze. The glaze comprises the following raw materials: 15-30 wt% of clay, 25-40 wt% of potassium feldspar, 5-15 wt% of calcite, 3-8 wt% of calcined talc, 10-25 wt% of quartz powder and 8-24 wt% of iron oxide. In addition, the invention also discloses a preparation method of the lead-free iron-based metallic glaze. According to the invention, through formula design, the used glaze does not use lead frit, mineral raw materials are used for assisting part of chemical raw materials, and iron is used as a main coloring and devitrification component, so that the iron-based decorative glaze surface with silver metal texture is obtained, the problem of single decorative effect caused by golden color in the prior art is solved, and the service life of the iron-based decorative glaze surface is prolonged. And the glaze is low in cost, environment-friendly, lead-free and novel in decorative effect, and has important significance on application and development of a metal texture decorative glaze technology.
本发明公开了一种无铅铁系金属质感釉面，其釉料的原料组成为粘土15～30wt％、钾长石25～40wt％、方解石5～15wt％、烧滑石3～8wt％、石英粉10～25wt％、氧化铁8～24wt％。此外，还公开了上述无铅铁系金属质感釉面的制备方法。本发明通过配方设计，所用釉料避免使用铅熔块，以矿物原料辅助以部分化工原料，以铁为主要着色及析晶成分，获得具有银色金属质感的铁系装饰釉面，不仅解决了现有技术以金色为主所导致的装饰效果单一的问题，而且成本低廉、环保无铅、装饰效果新颖，对于金属质感装饰釉面技术的应用和发展具有重要意义。
