Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of ceramic production process, and particularly relates to a microcrystalline drill ceramic tile and a preparation method thereof. BACKGROUND

[0002] Currently, there are mainly two kinds of processes for the flash effect ceramic tile on the market: one is to mix low-temperature dry particles and high-temperature dry particles together, and then to form a flash effect by means of the difference in light reflection amount of the low-temperature dry particles and the high-temperature dry particles after firing. This process has the following problems: the flash effect is not strong, the flash direction is single, and the anti-fouling ability is poor due to the large-area use of high-temperature dry particles; the other is to add zircon dry particles with high-refraction light effect into the high-temperature dry particles to form a flash effect by means of the light reflection of the zircon. However, due to the high melting point of the zircon dry particles and the need to rely on the light reflection characteristics of the zircon itself, fluxing materials cannot be used to melt the zircon dry particles during firing, which leads to the rough surface of the ceramic tile caused by the zircon particles on the surface of the ceramic tile, and the problem of glaze fouling. SUMMARY

[0003] To solve the above-mentioned problems of the flash effect ceramic tile, the present application develops a microcrystalline drill ceramic tile and a preparation method thereof, and the prepared microcrystalline drill ceramic tile has a fine glaze surface and a flash effect. The microcrystalline drill ceramic tile of the present application adjusts and optimizes the formula of the base glaze, the microcrystalline drill glaze and the functional glaze, reasonably sets and matches the melting temperatures of the three kinds of glazes, and adjusts the glazing amount to control the number of microcrystalline dry particles exposed on the glaze surface of the microcrystalline drill glaze, so as to meet the demand of the flash effect and solve the problem of glaze fouling.

[0004] To solve the above-mentioned problems, the present application realizes the following technical scheme:

[0005] The first application purpose of the present application is:

[0006] To provide a microcrystalline drill ceramic tile, which comprises: M62 base glaze, microcrystalline drill glaze and B10W functional glaze.

[0007] The M62 base glaze comprises the following mass percentage of raw material components:

[0008] 8-12% of calcined alumina, 18-22% of quartz powder, 22-26% of potassium feldspar, 12-15% of nepheline powder, 14-18% of kaolin, 2-6% of dolomite, 11-15% of zirconium silicate, and the sum of all components is 100%; 0.12% of sodium carboxymethyl cellulose, 0.25% of sodium tripolyphosphate, and appropriate amount of water are additionally added;

[0009] The M62 base glaze helps the body to discharge organic gas, reduces the generation of gas channels during firing, and further avoids the appearance of pinholes, thereby solving the problem of glaze fouling;

[0010] The microcrystalline drill enamel comprises microcrystalline dry particles, superfine high-temperature dry particles and suspending agent, and the mass ratio of the microcrystalline dry particles, the superfine high-temperature dry particles and the suspending agent is 5:40:100;

[0011] The microcrystalline dry particles are zircon micropowder particles with a particle size range of 160-250 mesh.

[0012] The superfine high-temperature dry particles have a particle size range of 300-320 mesh.

[0013] The ratio of the microcrystalline dry particles, the superfine high-temperature dry particles and the suspending agent is adjusted to achieve better brick surface texture and flash effect.

[0014] The superfine high-temperature dry particles comprise the following raw material components in mass percentage:

[0015] Potassium feldspar 35-49%, calcined talc 5-10%, calcite 8-16%, barium carbonate 5-9%, wollastonite 5-10%, zinc oxide 2-4%, calcined alumina 8-16%, and the sum of all components is 100%; additionally, sodium carboxymethyl cellulose 0.15-0.18%, sodium tripolyphosphate 0.2-0.3%, and appropriate amount of water.

[0016] The B10W functional enamel comprises the following raw material components in mass percentage:

[0017] Potassium feldspar 47-51%, kaolin 6-10%, barium carbonate 13-17%, zinc oxide 4-8%, dolomite 8-12%, calcite 8-16%, and the sum of all components is 100%; additionally, sodium carboxymethyl cellulose 0.12-0.15%, sodium tripolyphosphate 0.2-0.3%, and appropriate amount of water.

[0018] The melting temperature settings and reasonable matching of the M62 base glaze, the B10W functional glaze and the microcrystalline drill glaze in the application are as follows:

[0019] The melting temperature is adjusted and controlled by optimizing the formula ratio, the melting temperature of the M62 base glaze is controlled at about 1220 DEG C, the melting temperature of the B10W functional glaze is controlled at about 1215 DEG C, and the melting temperature of the microcrystalline drill glaze is controlled at about 1225 DEG C. Among them, the melting temperature of the M62 base glaze is slightly lower than the body temperature and is close to the body temperature; the melting temperature of the B10W functional glaze is lower than the melting temperature of the microcrystalline drill glaze, which is beneficial to the fluxing of the high-temperature superfine dry particles in the microcrystalline drill glaze, so that it is easy to melt and flatten, thereby improving the glaze quality. The high-temperature superfine dry particles are mixed with the microcrystalline dry particles by the suspending agent and wrap the microcrystalline dry particles, and are uniformly distributed. In this way, by adjusting the glazing amount, the number of the microcrystalline dry particles exposed on the glaze surface in the microcrystalline drill glaze can be controlled to meet the flash demand, thereby solving the glaze dirt problem.

[0035] The specific gravity of the glaze slurry of the microcrystalline drill enamel is 1.15-1.20, and the glazing amount is 277±5 g / m 2 .

[0038] The second inventive purpose of the present application is as follows:

[0039] A preparation method of the microcrystalline drill ceramic tile is provided, which comprises the following preparation steps:

[0040] S1. Preparing a body, and applying M62 base glaze to the body to obtain a tile body A;

[0041] S2. Applying B10W functional glaze to the tile body A to obtain a tile body B;

[0042] S3. Printing a design inkjet pattern on the tile body B to obtain a tile body C;

[0045] S6. High-temperature firing the tile body E to obtain a tile body F;

[0046] S7. Brushing, edge grinding, sorting, packaging, and warehousing the tile body F to obtain the microcrystalline drill ceramic tile.

[0047] The preparation method of the microcrystalline drill ceramic tile is further optimized as follows:

[0048] The M62 base glaze comprises the following preparation steps:

[0049] According to the M62 base glaze formula, the corresponding raw material components are weighed, ball milled, slurry discharged, and passed through a 325 mesh screen to prepare M62 base glaze slurry for standby use;

[0050] The microcrystalline drill glaze comprises the following preparation steps:

[0051] According to the microcrystalline drill enamel formula, the corresponding raw material components are weighed and uniformly mixed, so that the microcrystalline drill enamel is obtained.

[0052] The superfine high-temperature dry particles comprise the following preparation steps:

[0053] According to the superfine high-temperature dry particle formula, the corresponding raw material components are weighed and uniformly mixed, melted at 1625 DEG C, and kept for 8-12 hours, then slowly cooled to room temperature at a cooling rate of 8-20 DEG C / h, so that the crystal is precipitated, the dry particles of 300-320 meshes are broken and sieved, and the superfine high-temperature dry particles are prepared.

[0054] The suspension agent comprises the following preparation steps:

[0058] The microcrystalline drill ceramic tile and the preparation method thereof have the following innovative features:

[0059] 1. The fine sparkling points are formed by the reflection of direct light on the microcrystalline drill dry particles, and the irregular shape of the microcrystalline dry particles enables the light to be reflected from all directions, thereby forming the sparkling effect.

[0060] 2. In order to solve the problems of rough hand feeling and poor stain resistance of the sparkling dry particle product, the production process is optimized in the following aspects: the microcrystalline dry particles with a particle size of 160-250 meshes, the superfine high-temperature dry particles with a particle size of more than 300 meshes and the suspension agent are mixed in a ratio of 5:40:100 (the optimal ratio) to prepare the microcrystalline drill enamel.

[0061] 3. A low-temperature functional glaze (B10W functional glaze) is developed by debugging, which can help to fuse the high-temperature superfine dry particles in the microcrystalline drill enamel. After the B10W functional glaze is melted, it can wrap the high-temperature superfine dry particles in the microcrystalline drill enamel, preventing the high-temperature superfine dry particles from falling off and improving the smooth and delicate texture of the high-temperature superfine dry particles. After the ceramic tile is polished by a polishing line, the surface texture is delicate and the stain resistance is good.

[0062] In the B10W functional glaze formula:

[0063] (1) Introducing potassium feldspar. Potassium feldspar is a strong flux raw material, which has a fluxing effect, can reduce the firing temperature of the glaze, and can improve the refractive effect of the glaze surface and improve the quality of the glaze surface.

[0064] (2) Introducing an appropriate amount of dolomite and calcite. In B10W functional glaze, SiO2 particles and calcite, calcite in dolomite produce bubble scattering at high temperature, which can significantly improve the texture of the glaze. In addition, calcium oxide can improve the chemical stability of the glaze, enhance the suspension of the glaze, and improve the fluxing effect.

[0065] (3) Introducing an appropriate amount of zinc oxide. Adding zinc oxide to B10W functional glaze can make the glaze more fusible and reduce the firing temperature. Zinc oxide can play a good role in the mechanical strength, elasticity, melting performance and fire resistance of the glaze, while expanding the firing range of the glaze and improving the color development ability.

It should be understood that the examples are only used to illustrate the present application, but not to limit the protection scope of the present application, and any simple improvement of the preparation method of the present application within the concept of the present application is within the protection scope of the present application.

[0069] Example 1 Process debugging research and analysis

[0070] The microcrystalline dry particles themselves reflect direct light to form fine sparkling points. Due to the irregular shape of the microcrystalline dry particles, light reflection of different intensities can be performed when light is incident from various directions, thereby forming a sparkling effect. The particle size selection of microcrystalline dry particles and ultra-fine high-temperature dry particles is particularly critical. If the particle size is too large, the glaze surface will be rough and prominent, affecting the stain resistance. If the particle size is too small, the sparkling effect will be poor.
