Description

Technical Field

[0001] The invention belongs to the technical field of ceramic production technology, and specifically relates to a microcrystalline diamond tile and a preparation method thereof. Background Art

[0002] There are two main types of flashing effect tile processes on the market: one is to mix low-temperature dry particles and high-temperature dry particles together, and after firing, use the difference in the amount of light reflected by the low-temperature dry particles and the high-temperature dry particles to form a flashing effect. This process has the following problems: the flashing effect is not strong, the flashing direction is single, and the anti-fouling ability is poor due to the large-scale use of high-temperature dry particles; the other is to add zircon dry particles with high refractive light effect to the high-temperature dry particles, and form a flashing effect through the reflection of zircon by light. However, due to the high melting point of zircon dry particles and the need to rely on the light reflection characteristics of zircon itself, it is impossible to use fluxing materials to melt zircon dry particles during firing, which causes the zircon particles on the surface of the tile to make the tile surface rough, which is prone to glaze stain absorption problems. Summary of the invention

[0003] In order to solve the shortcomings of the above-mentioned tiles with flashing effects, the present invention has developed a microcrystalline diamond tile and a preparation method thereof. The prepared microcrystalline diamond tile has both a delicate glaze and a flashing effect. The microcrystalline diamond tile of the present invention adjusts and optimizes the formula of the base glaze, microcrystalline diamond glaze and functional glaze, and reasonably sets and matches the melting temperatures of the three glazes, and controls the number of microcrystalline dry particles in the microcrystalline diamond glaze exposed on the glaze surface by adjusting the glazing amount, so as to meet the needs of the flashing effect and solve the problem of glaze surface pollution absorption.

[0004] To solve the above problems, the present invention is implemented through the following technical solutions:

[0005] The first object of the present invention is:

[0006] Provided is a microcrystalline diamond tile, which includes: M62 base glaze, microcrystalline diamond glaze and B10W functional glaze;

[0007] The M62 base glaze comprises the following raw material components in percentage by weight:

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

[0009] The M62 base glaze helps the green body to discharge organic gases, reduces the generation of gas channels during the firing process, thereby avoiding the appearance of pinholes and solving the problem of glaze surface absorption of dirt;

[0010] The microcrystalline diamond glaze comprises microcrystalline dry particles, ultrafine high-temperature dry particles and a suspending agent, and the mass ratio thereof is: microcrystalline dry particles: ultrafine high-temperature dry particles: suspending agent = 5:40:100;

[0011] The microcrystalline dry particles are zircon powder particles with a particle size range of 160 to 250 meshes;

[0012] The particle size of the ultra-fine high-temperature dry particles ranges from 300 to 320 meshes;

[0013] By adjusting the ratio of microcrystalline dry particles, ultrafine high-temperature dry particles and suspending agent, better brick surface texture and sparkling effect can be achieved.

[0014] The ultra-fine high-temperature dry particles include the following raw material components in percentage by weight:

[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%, the sum of all components is 100%; add sodium carboxymethyl cellulose 0.15-0.18%, sodium tripolyphosphate 0.2-0.3%, and an appropriate amount of water;

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

[0019] By optimizing the formula ratio to adjust and control the melting temperature, the melting temperature of M62 base glaze is controlled at about 1220℃, the melting temperature of B10W functional glaze is controlled at about 1215℃, and the melting temperature of microcrystalline diamond glaze is controlled at about 1225℃. Among them, the melting temperature of M62 base glaze is slightly lower than the body temperature and close to the body temperature; the melting temperature of B10W functional glaze is lower than the melting temperature of microcrystalline diamond glaze, which is conducive to the melting of high-temperature ultrafine dry particles in microcrystalline diamond glaze, making it easy to melt flat, thereby improving the quality of the glaze. The high-temperature ultrafine dry particles are mixed with microcrystalline dry particles through a suspending agent and encapsulate the microcrystalline dry particles, and are evenly distributed. In this way, by adjusting the glazing amount, the amount of microcrystalline dry particles in the microcrystalline diamond glaze exposed on the glaze surface can be controlled to meet the needs of flashing, thereby solving the problem of glaze surface pollution absorption.

[0038] The second object of the present invention is:

[0039] A method for preparing the aforementioned microcrystalline diamond 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 brick body A;

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

[0042] S3. Printing a designed inkjet pattern onto the brick body B to obtain a brick body C;

[0046] S7. The brick body F is subjected to brushing, polishing, edge grinding, sorting, packaging, and warehousing to obtain the microcrystalline diamond ceramic tile.

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

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

[0049] According to the M62 base glaze formula, corresponding raw material components are weighed, ball-milled, slurried, and passed through a 325-mesh sieve to prepare an M62 base glaze slurry for later use;

[0053] According to the ultrafine high-temperature dry granule formula, the corresponding raw material components are weighed, mixed evenly, melted at 1625°C, kept warm for 8 to 12 hours, and then slowly cooled to room temperature at a cooling rate of 8 to 20°C / h to precipitate crystals, crushed, and screened to obtain the ultrafine high-temperature dry granules;

[0058] The microcrystalline diamond ceramic tile and the preparation method thereof of the present invention have the following innovative features:

[0059] 1. The microcrystalline dry particles themselves reflect direct light to form tiny flash points. The irregular shape of the microcrystalline dry particles allows light to be reflected to varying degrees when it enters from all directions, thus forming a flash effect.

[0060] 2. In order to solve the problem of rough hand feel and poor antifouling performance of the flash dry granule product, the present invention optimizes the production process in the following aspects: microcrystalline dry particles with a particle size of 160 to 250 meshes, ultrafine high-temperature dry particles with a particle size of more than 300 meshes and a suspending agent are mixed with the suspending agent in a ratio of 5:40:100 (optimal ratio) to make microcrystalline diamond glaze.

[0061] 3. Through debugging, a low-temperature functional glaze (B10W functional glaze) was developed, which helps to melt the high-temperature ultra-fine dry particles in the microcrystalline diamond glaze. After melting, the B10W functional glaze can wrap the high-temperature ultra-fine dry particles in the microcrystalline diamond glaze, preventing the high-temperature ultra-fine dry particles from falling off and improving the smooth and delicate texture of the high-temperature ultra-fine dry particles. After the tiles are swept by the polishing line after leaving the kiln, the surface texture is delicate and the anti-fouling performance is good.

[0062] In the B10W functional glaze formula:

[0063] (1) Introducing potassium feldspar. Potassium feldspar is a strong flux material that 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 glaze surface quality.

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

[0065] (3) Introduce an appropriate amount of zinc oxide. Adding zinc oxide to B10W functional glaze can make the glaze easier to melt and reduce the firing temperature. Zinc oxide can play a good role in the mechanical strength, elasticity, melting properties and refractory properties of the glaze, while expanding the firing range of the glaze and improving the coloring ability.

[0068] In order to make the application, technical scheme and advantages of the present invention more clear, the present invention is described in detail in conjunction with specific embodiments. It should be understood that the embodiments are only used to illustrate the present invention, but not to limit the protection scope of the present invention. All simple improvements to the preparation method of the present invention under the premise of the concept of the present invention belong to the protection scope of the present invention.

[0069] Example 1 Process Debugging Research and Analysis

[0070] The microcrystalline dry particles themselves reflect direct light to form tiny flashing spots. Due to the irregular shape of microcrystalline dry particles, when light enters from all directions, it can reflect light of different intensities to form a flashing effect. The particle size selection of microcrystalline dry particles and ultrafine high-temperature dry particles is particularly critical. Too large a particle size will result in a rough and prominent glaze surface, affecting the anti-fouling performance. Too small a particle size will deteriorate the flashing effect.

[0072]

[0073]

[0074] The experimental results show that J2, J3 and J8 have excellent effects. Therefore, the preferred particle size of the microcrystalline dry particles in the present invention is 160-250 mesh; the particle size of the ultrafine high-temperature dry particles is above 300 mesh, and the preferred particle size is 300-320 mesh.

[0077]
