Description

Composition for preparing ceramic overglaze, ceramic brick with mold texture, and preparation method and application thereof
Technical Field
The application relates to the technical field of ceramic bricks, in particular to a composition for preparing ceramic overglaze, a ceramic brick with mould textures, and a preparation method and application thereof.
Background
The archaized brick with the mould texture is visually similar to natural stone, is deeply favored by consumers, avoids product homogenization, and greatly increases the competitiveness of archaized products. The mould texture on the archaizing brick with the mould texture is mainly produced by a mould pressing method at present, but the mould texture formed by the method is single and fixed, the same pattern is difficult to coincide and can not form more realistic archaizing products, and the mould is worn along with the increase of pressing times, so that the mould texture is not fine. To solve the above technical problems, a technique of generating a mold texture by mutually repelling aqueous overglaze slurry and oily ink or stripping overglaze by corrosive ink has been developed. However, the technology can ensure the depth of the texture of the mould on the glaze surface due to the fact that the surface glaze needs a higher initial melting point and a higher sintering temperature, the glaze formula is often made of materials with higher melting points, the whole glaze formula is higher in maturation temperature, the glaze has partial raw sintering components under the condition that the sintering temperature is unchanged, the glaze surface of the product is easy to store and absorb dirt, and the product is not attractive after being paved.
Therefore, there is a need for techniques that utilize the mutual repulsion of aqueous overglaze slurries and oily inks to create mold textures that improve the stain resistance of the resulting overglaze.

The ceramic tile with the mould texture contains a specific content of B in the surface glaze layer 2 O 3 、K 2 O、Na 2 O and Li 2 The above oxides have stronger fluxing action, and are beneficial to forming more glass phases and various crystals on the glaze surface, so that the ceramic tile glaze surface has better antifouling performance. Under the combined action of chemical components, the overglaze layer forms various crystals with different refractive indexes for light, such as potassium-sodium feldspar crystals, anorthite crystals and zinc-aluminum spinel crystals, and various tiny crystals are uniformly distributed on the glaze surface to form diffuse reflection for the light, so that the glaze surface is matt and glossy, has high hardness and small high-temperature deformation, and can keep the original texture shape of the die in the sintering process. The application of CaO forms anorthite crystals with higher hardness after firing, B 2 O 3 The application of (A) can obviously improve the hardness of the glaze surface, B 2 O 3 With boron-oxygen tetrahedra [ BO4 ]]In the form of a pattern, the hardness of the glaze is greatly increased. The application of the two components increases the hardness of the glaze together, thereby improving the wear resistance of the glaze.

The ceramic tiles with mold textures obtained in each example and comparative example were subjected to performance measurement, and the specific test method is as follows:
(1) Stain resistance test: according to standard GB/T3810.14-2016;
(2) Abrasion resistance test: according to standard GB/T4100-2015;
(3) And (3) testing the grain fineness of the die: visual inspection was performed.
(4) The color evaluation standard of the texture pits is that the visual tone quality is the basis, the optimal value is 10 parts, and the color evaluation standard is sequentially reduced to be inferior.
The test results are shown in Table 1.
TABLE 1
As can be seen from Table 1, the ceramic tiles with the mold textures obtained in each example had good antifouling properties, and the antifouling grade was 5.
Example 1 in comparison with comparative examples 1 to 2, 5 to 7, it is known that B is introduced into the overglaze layer by adding borocalcite and spodumene 2 O 3 And Li (lithium) 2 O can improve the antifouling performance of the glaze. When the amount of the loam is too small, B is contained in the glaze formulation 2 O 3 And the CaO content is too much, the firing temperature of the glaze formula is too low, so that the overburning is caused during firing, pinholes are generated, and the wear resistance and the antifouling performance are causedThe performance is low; when the amount of the loam is too large, the fluxing property is too high, so that the firing temperature of the glaze formulation is low, and the antifouling property is deteriorated due to too little formation during firing. When the spodumene consumption is too small, the flux material is reduced, and the firing temperature of the glaze formula is higher, so that the glaze is fired, and the antifouling performance is poor; when the spodumene is used in an excessive amount, the firing temperature of the glaze formulation is low due to the excessive flux, and the stain-proofing performance is poor due to the overburning phenomenon during firing.
As can be seen by comparing example 1 with comparative examples 3-4, the amounts of nepheline and bentonite in the aqueous overglaze slurry affect the antifouling properties of the glaze. When the amount is too small, the flux material in the nepheline is relatively reduced, which results in a high firing temperature of the glaze formulation, and in the firing, firing occurs, which results in deterioration of the antifouling property; when the amount is too large, the amount of Al2O3 in bentonite is too large, which results in a high firing temperature of the glaze formulation, and the firing occurs during firing, which results in deterioration of the antifouling property.
Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the present application and not for limiting the scope of the present application, and although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the present application may be modified or substituted equally without departing from the spirit and scope of the technical solution of the present application.
