A glazed three-dimensional gold-plated combined glazed brick comprises a finished product A, a finished product B and a finished product C, wherein the finished product A, the finished product B and the finished product C are combined for use when being paved;
the finished product A sequentially comprises a brick blank layer, a pattern layer, a transparent glaze layer, a first three-dimensional glaze layer and a first gold-plated layer from bottom to top;
the finished product B sequentially comprises a brick blank layer, a pattern layer, a transparent glaze layer, a first three-dimensional glaze layer, a second three-dimensional glaze layer and a second gold-plated layer from bottom to top;
the finished product C sequentially comprises a brick blank layer, a pattern layer, a transparent glaze layer, a first three-dimensional glaze layer, a second three-dimensional glaze layer, a third three-dimensional glaze layer and a third gold-plated layer from bottom to top;
the first three-dimensional glaze layer, the second three-dimensional glaze layer, the third three-dimensional glaze layer, the first gold-plated layer, the second gold-plated layer and the third gold-plated layer are all upwards exposed on the transparent glaze layer.
The invention relates to an overglaze three-dimensional gilded combined glazed brick, which is characterized in that a first three-dimensional glaze layer, a second three-dimensional glaze layer and a third three-dimensional glaze layer are respectively distributed in a set area above a pattern layer according to the design of the pattern, transparent glaze layers are distributed among the first three-dimensional glaze layer, the second three-dimensional glaze layer and the third three-dimensional glaze layer, semi-finished products containing the first three-dimensional glaze layer, the second three-dimensional glaze layer and the third three-dimensional glaze layer are respectively subjected to metal electroplating to prepare a finished product A, a finished product B and a finished product C, the surface of the glaze layer of the overglaze brick paved and pasted in a combined mode has a staggered three-dimensional structure, and the combined product has a very high 3D (three-dimensional) painting artistic effect.
As shown in fig. 1-4, fig. 1 and 2 show finished product type a glazed tiles, fig. 3 shows finished product type B glazed tiles, fig. 4 shows finished product type C glazed tiles, and fig. 5 shows that the overall effect of the combined and paved multiple finished products a, B and C not only reflects the artistry of the background pattern, but also has a good three-dimensional effect.
The combined glazed tile with the stereoscopic gold-plated glaze solves the technical problem that the artistic quality and the stereoscopic effect of the glazed tile in the prior art are difficult to combine.
Specifically, the heights of the first three-dimensional glaze layer, the second three-dimensional glaze layer and the third three-dimensional glaze layer which protrude upwards from the transparent glaze layer are 0.1-0.3mm, 0.3-0.5 mm and 0.3-0.8mm respectively.
The three-dimensional glaze layers with different heights protruding upwards can enable the finished product A, the finished product B and the finished product C to have better artistry after being paved and combined.
Specifically, the first three-dimensional glaze layer, the second three-dimensional glaze layer and the third three-dimensional glaze layer comprise transparent dry grains with different grain diameters;
the transparent dry granules comprise the following chemical components in percentage by weight: SiO 22 62-68%、Al2O3 5-9%、Fe2O3 0.5-1%、CaO 4-6%、MgO 1-3%、K2O 2-3.5%、Na2O 3.5-5%、TiO2<0.05%、B2O3 10-13%、PbO <0.01%、ZnO 1-2%、ZrO2 <0.05%、BaO ：3-5%、Li2O <0.05%、SrO<0.01%、Cs2O <0.01%、MnO<0.01%、 RbO<0.01%、CdO<0.01%、 F<0.05%、 P2O5<0.05%、SO3<0.05% and loss on ignition<0.05%。
The higher content of silicon dioxide can lead the transparent dry particles to have higher sintering temperature and reduce the speed of melting and leveling so as to obtain better three-dimensional effect. The abundant metal and rare metal can increase the change of the reflected light of the first three-dimensional glaze layer, the second three-dimensional glaze layer and the third three-dimensional glaze layer and the glittering and translucent effect.
Further, the grain diameters of the transparent dry grains of the first three-dimensional glaze layer, the second three-dimensional glaze layer and the third three-dimensional glaze layer are respectively 150-250 meshes, 70-120 meshes and 30-60 meshes.
Has the advantages that: the different particle size distribution enables the first three-dimensional glaze layer, the second three-dimensional glaze layer and the third three-dimensional glaze layer obtained after firing to have different thicknesses.
Specifically, the transparent glaze layer comprises the following chemical components in percentage by weight:
Al2O3 13-18%、SiO2 53-58%、Fe2O3 <0.1%、CaO 2-4.5%、MgO 0.3-1.5%、TiO2 <0.05%、B2O316-19%, ZnO 1-2%, BaO 3-5% and Li2O <0.05%。
The content of silicon dioxide contained in the transparent glaze layer is lower than that of transparent dry particles, so that gaps among the transparent dry particles of the first three-dimensional glaze layer, the second three-dimensional glaze layer and the third three-dimensional glaze layer can be fully filled in the transparent glaze layer, and the overglaze three-dimensional gold-plated combined glazed polished tile can obtain a complete transparent glaze surface layer.
Furthermore, the invention also provides a preparation method of the overglaze three-dimensional gold-plated combined glazed tile, which is used for preparing the overglaze three-dimensional gold-plated combined glazed tile;
comprises a finished product A preparation step, a finished product B preparation step and a finished product C preparation step;
