As the most preferred scheme, the light-transmitting brick blank is prepared from the following raw materials in percentage by mass: 85% of light-transmitting blank frit, 12% of clay, 1.5% of binder and 1.5% of colorant, wherein the sum of the mass percentages of the components is 100%; the light-transmitting blank frit is prepared from the following raw materials in parts by weight: 39 parts of potassium feldspar, 30 parts of albite, 16 parts of dolomite, 6 parts of alumina, 3 parts of barium carbonate and 6 parts of soda ash.
More preferably, the binder is one of carboxymethyl cellulose and polyvinyl alcohol, and the colorant is a ceramic colorant.
The reason why the present invention achieves the light transmitting effect and the high hardness effect is that: on one hand, the content of Ca and Mg in the transparent blank frit is specifically increased and the content of K, Na is reduced by improving the formula of the blank, so that the transparent blank frit has transparent texture and a transparent function, but if the blank is made of the transparent blank frit alone, the transparent blank frit is easy to disperse and cannot be molded; on the other hand, the clay is an important inorganic mineral raw material by adding the clay and the binder, is composed of various kinds of water aluminum silicate and a certain amount of aluminum oxide, alkali metal oxide and alkaline earth metal oxide, and contains impurities such as quartz, feldspar, mica, sulfate, sulfide, carbonate and the like. And the binder is an organic binder. This application improves the adhesive force between the frit through inorganic clay and organic binder as the adhesive between the printing opacity blank frit to improve the hardness of body. The research finds that the mineral particles on the clay have electronegativity, so the clay has good physical adsorption and surface chemical activity, has the capacity of exchanging and replacing other cations and forms better crosslinking action with an organic binder. Therefore, the reasonable proportion of the inorganic clay and the organic binder can greatly increase the hardness and the wear resistance of the green body under the condition of not influencing the transmittance, so that the hardness of the green body can reach 5.5 grades of Mohs hardness, is similar to the hardness of the existing opaque green body, and is far higher than the Mohs hardness of a single transparent green body by 3-4 grades, thereby improving the application range of the transparent brick green body and having wider application scenes.
