Heat-absorbing ceramic glaze, preparation method thereof and heat-absorbing ceramic tile
The invention belongs to the technical field of architectural ceramics, and particularly discloses a heat-absorbing ceramic glaze, a preparation method thereof and a heat-absorbing ceramic tile. The heat-absorbing ceramic glaze comprises the following raw material components: basic glaze and a heat absorber, the heat absorber comprises indium tin oxide and/or antimony tin oxide, and the chemical composition of the basic glaze contains Li2O and/or Na2O. According to the heat-absorbing ceramic glaze disclosed by the invention, the absorption effect of ITO and/or ATO on near-infrared light is fully exerted, and meanwhile, Li < + > and/or Na < + > with relatively small ion radius are/is introduced into the basic glaze to accelerate the replacement of Si < 4 + > in a glaze system on Sn < 4 + > in ITO and/or ATO particles, so that carriers of ITO and/or ATO are mainly represented as absorption on near-infrared light after the ITO and/or ATO are fired at a high temperature, and the heat-absorbing effect of the ITO and/or ATO on near-infrared light is improved. The heat absorption effect of the glaze is achieved. The heat-absorbing ceramic glaze disclosed by the invention greatly widens the application range of the heat-absorbing ceramic tile, and the heat-absorbing effect is more obvious than that of the heat-absorbing ceramic tile which only depends on the dark color of the tile body.
本发明属于建筑陶瓷技术领域，具体公开了一种吸热陶瓷釉料及其制备方法、吸热陶瓷砖。吸热陶瓷釉料的原料组分包括基础釉料和吸热剂，其中：吸热剂包括氧化铟锡和/或氧化锑锡，基础釉料的化学组成中含有Li2O和/或Na2O。本发明的吸热陶瓷釉料充分发挥ITO和/或ATO对近红外光的吸收作用，同时通过在基础釉料中引入离子半径较小的Li+和/或Na+，以加快釉料体系中Si4+对ITO和/或ATO颗粒中Sn4+的替换，使ITO和/或ATO经高温烧成后，其载流子主要表现为对近红外光的吸收，以实现釉料的吸热功效。本发明的吸热陶瓷釉料大大扩宽了吸热陶瓷砖的应用范围，且吸热效果较仅依赖砖体的深颜色更为显著。
