Problems solved by technology

The natural Australian sandstone is made from sandstone imported from Australia, which is a non-renewable resource. Natural materials are rare and costly. In addition, pure sandstone has too low flexural strength, cannot be cleaned hygienically, and is easy to fade after exposure to sunlight, which cannot meet the needs of the current construction industry Therefore, it is very important to produce a tile that can achieve the natural and real Australian sandstone effect formed by nature.
Since the natural Australian sandstone has a texture between thickness and thickness and multi-level particles formed by the mixture of various minerals and terrain changes, it is difficult to prepare tiles with the effect of natural and real Australian sandstone, especially in imitation Australian sandstone texture and texture. There are great technical difficulties in the texture. At present, there are few studies on the imitation of natural Australian sandstone, and the simulation effect of the prepared imitation Australian sandstone is not ideal.

Embodiment 1

[0070] A production process of imitating Australian sandstone ceramic tiles is as follows:

[0071] (1) The raw materials of tile blanks in Table 1 are ball milled to obtain blank powder. The fineness of the blank powder is 250 mesh sieves, and the sieve residue is 1%. The chemical composition of tile blanks is shown in Table 2. After molding by a press, Dry to obtain tile blanks, wherein, the press adopts Italian 3590T, and the production pressure is 3100KN; a layer of makeup soil is wetted on one surface of the tile blank (600mm*600mm), the specific gravity of the makeup soil is 1.5, and 130g is applied. The ingredients are shown in Table 3.

[0072] Wherein, the raw material of ceramic tile base is as shown in table 1:

Embodiment 2

[0106] A production process of imitating Australian sandstone ceramic tiles is as follows:

[0107] (1) The raw materials of tile blanks in Table 1 are ball milled to obtain blank powder. The fineness of the blank powder is 300 mesh sieves, and the sieve residue is 1%. The chemical composition of the tile blanks is aluminum 23%, silicon 66%, iron 0.5%, 0.4% titanium, 0.9% calcium, 0.5% magnesium, 3.0% potassium, 2% sodium, and 3.7% other impurities. After being formed by a press, it is dried to obtain a tile blank. Among them, the press is 3590T in Italy. The pressure is 3000KN; wet a layer of makeup soil on one surface of the tile blank (600mm*600mm), the specific gravity of the makeup soil is 1.45, apply 125g, and the chemical composition is K 2 O 3.67%, Na 2 O 1.2%, Al 2 O 30%, SiO 2 65.0%, CaO 0.03%, MgO 0.1%.

Abstract

The invention discloses a ceramic tile made of simulated sandstone and a preparation process of the ceramic tile. The ceramic tile comprises a ceramic tile green body and an enamel layer on the surface of the ceramic tile green body. The ceramic tile is characterized in that stone-shaped stripes and ink jet coarse sandstone patterns are printed on the surface of the enamel layer, the enamel layer sequentially comprises a bottom enamel layer, a surface enamel layer, a first-time dot enamel layer, a second-time dot enamel layer, a protection enamel layer and a dry granular enamel layer, an area of the first-time dot enamel layer accounts for 95-99.9% that of the surface of the ceramic tile, and an area of the second-time dot enamel layer accounts for 70-90% of that of the ceramic tile. Processes of repeated enameling and distributing, drum, ink jet, dry granule distributing and single-roller letterpress printing are adopted, multilayer texture and multilayer enamel color are formed, and an effect like natural real sandstone formed by nature is completely realized.

Description

technical field [0001] The invention belongs to the technical field of architectural ceramics, and in particular relates to a ceramic brick for simulating stone sandstone and a preparation process thereof. Background technique [0002] As an important building decoration material, tiles are widely used due to their advantages of high strength, high hardness, high temperature resistance and corrosion resistance. Ceramic tiles are formed from refractory metal oxides and semi-metal oxides through the process of grinding, mixing, pressing, glazing, and sintering to form an acid and alkali resistant porcelain or stone building decoration material. Its raw materials are mostly made of clay, quartz sand and other mixtures. Over the centuries, the decorative effect of ceramic tiles has increased as the methods of tile production have improved. [0003] Ceramic tiles can be divided into glazed tiles, whole body tiles, vitrified tiles and mosaics according to their production proces...
