Problems solved by technology

If the sintering system of these iron oxides with unstable valence is not properly controlled, the color of the green body will change easily during the sintering process, and it will easily deform and cause defects such as green foam and pinholes, which will limit its application in the production of ceramic wall and floor tiles.

Embodiment 1-5

[0026] In the following examples, the main chemical components of the building red brick waste selected in the raw materials are: silicon dioxide 72.03%, aluminum oxide 15.13%, ferric oxide 6.10%, potassium oxide 2.26%, loss on ignition 0.97%, and the rest The composition is undetermined; the plastic clay is yellow clay, and its main chemical composition is: silicon dioxide 71.81%, aluminum oxide 14.5%, ferric oxide 4.17%, potassium oxide 2.96%, loss on ignition 4.14%, and other components is undetermined. Those of ordinary skill in the art should understand that the chemical components given here are exemplary, and the chemical components of building red brick waste and plastic clay in different regions will have certain differences, but the content of ferric oxide in the building red brick waste ≥ 5%.

[0027] After the red brick waste is cleaned, it is crushed with a jaw crusher, and the particles with a particle size of less than 5cm are selected and put into the homogeni...

Embodiment 6

[0043] Because the printing layer is not wear-resistant more, for this reason, the present invention provides following embodiment 6

[0044] The formula and process as in Example 3 are selected, the difference is that after inkjet printing, a layer of transparent or translucent glaze is applied to form a surface glaze layer.

[0045] In this example, the formula of the selected surface glaze layer glaze is: glaze powder 85%, transparent frit 10%, kaolin 5%, wherein the chemical composition of glaze powder is: silicon dioxide 47.34%, oxide Aluminum 20.16%, ferric oxide 0.18, titanium dioxide 0.23, calcium oxide 10.30%, magnesium oxide 4.50%, potassium oxide 1.25%, sodium oxide 3.37%, barium oxide 2.23, zinc oxide 1.28, zirconium oxide 1.49, loss on ignition 7.67% , Moreover, the glaze with the above ratio can make the ceramic inkjet printing ink better in color and make the printing pattern more gorgeous. Glazing thickness is 0.01-0.1mm.

Abstract

The invention provides a glazed tile produced by waste materials of red bricks, and a producing method thereof. The glazed tile comprises a blank body layer, a ground coat layer and a stenciled decoration layer from bottom up, wherein the blank body layer is prepared by the following steps: using the following components in percent by weight: 20-40 percent of the waste materials of the red bricks, 20-40 percent of plastic clay soil, 10-30 percent of potassium feldspar, 15-20 percent of kaolinite and 2-5 percent of soapstone as blank body raw materials, performing punch forming, and then performing baking at an oxidative atmosphere. Compared with the prior art, the method has the following advantages: firstly, in the technical scheme of the method, a recovery processing process of the waste materials of the red bricks is simple, and a great amount of waste materials of the building red bricks can be consumed; secondary, iron elements in the blank body layer can be completely converted into ferric oxide, so the performance is stable and unitive; thirdly, defects that the blank body layer is easy to deform and quantities of blank bubbles and pinholes are more in a high-temperature sintering process as the content of the iron elements is high are overcome.

Description

technical field [0001] The invention relates to a comprehensive utilization technology of construction waste materials, in particular to a production method of glazed bricks using red brick waste materials. Background technique [0002] Commonly known as clay bricks, red bricks refer to iron-rich yellow clay, shale, coal gangue, etc. Sintered building bricks fired with an oxidizing flame. Before the 1990s, it was widely used as a main building material. However, red bricks have a huge demand for clay and cause serious damage to the environment. In the mid-1990s, the country banned the production and sales of red bricks. Since the beginning of the 21st century, with the acceleration of the transformation of old cities and the construction of new urbanization, these red bricks have been widely used as wall materials in old Chinese buildings, masonry columns, arches, industrial chimneys, ground walls and other basic constructions. It has been replaced by new environmentally ...
