[0041] Provided is a method for preparing fine concave-convex surface matte tiles, comprising:
[0042] Step 1: Preparation of green body powder: ball mill according to the conventional green body formula to obtain mud, and the obtained mud material is granulated in a spray drying tower to obtain a powder with a certain particle size distribution and moisture content;
[0043] Step 2: Pressing and molding the green body with fine concave-convex surface: pressing the powder obtained in step 1 on a press to obtain a green body;
[0044] Step 3: Drying the green body in the drying kiln: send the green body obtained in step 2 into the drying kiln for drying, the drying temperature is 180-230°C, and the drying time is 60-80 minutes to obtain a dried body, and the moisture content of the dried body is controlled at 0.3- 0.6%;
[0045]Step 4: Drizzle the surface glaze: use a bell jar to pour the surface glaze glaze onto the surface of the dry billet obtained in step 3, and the proce...
Embodiment 1
[0054] A method for preparing fine concave-convex surface matt tiles is provided, the process flow of which is as follows:
[0055] Step 1: Preparation of green body powder: ball mill according to the conventional green body formula to obtain mud, and the obtained mud material is granulated in a spray drying tower to obtain a powder with a certain particle size distribution and moisture content;
[0056] Step 2: Press molding of fine concave-convex surface green body: Press the powder obtained in step 1 on a press to obtain a green body. The pressed mold is a PETG material that has been carved with fine concave-convex natural texture by a laser engraving machine;
[0057] Step 3: drying the green body in the drying kiln: send the green body obtained in step 2 into the drying kiln for drying, the drying temperature is 190°C, and the drying time is 70 minutes to obtain a dried body, and the moisture content of the dried body is controlled at 0.4%;
[0058] Step 4: Drizzle the to...

Abstract
The invention provides a fine concave-convex surface matte ceramic tile and a preparation method thereof, wherein the ceramic tile comprises a green body layer with a concave-convex texture, a cover coat composed of feldspar calcium glaze is arranged on the green body layer, a pattern layer is arranged on the cover coat, and a dry granular glaze layer is arranged on the pattern layer, wherein according to the parts by mass, a glaze material of the dry granular glaze layer comprises the following components including, 20-50 parts of low-temperature glaze slip, 10-50 parts of high-temperature dry granules, 50-100 parts of medium-temperature dry granules, 30-50 parts of high-temperature matte powder and 200-400 parts of a dry granular suspending agent, wherein the specific gravity of the low-temperature glaze slip is 1.85-1.95 g / ml. According to the ceramic tile, the composition proportioning scheme of the components of the dry granular glaze layer and cover glaze is originally provided; and in the technological process of the matte ceramic tile, the manufacturing processes of fine molds, fine dry granular glaze pouring and brushing and polishing are adopted, the matte ceramic tile is further matte, the ceramic tile which is good in stereoscopic impression and layering sense, obvious in glimmer and matt contrast, smooth and fine is obtained, and the comfort of the whole decoration space is improved.
Description
technical field [0001] The invention relates to the field of ceramic tiles, in particular to a matte ceramic tile with a fine concave-convex surface and a preparation method thereof. Background technique [0002] According to the survey, long-term exposure to various light pollution in the surrounding environment is one of the main reasons why the myopia rate of young people in my country remains high, and the survey also shows that after watching TV for several hours, people's vision will temporarily drop by 30%. Therefore, if you live indoors in a living environment with smooth walls and floors for a long time, the light reflection generated by the smooth walls and floors will stimulate the retina, exceed the coordination of the eyes, cause eye fatigue, and even reduce visual function. Therefore, in order to minimize the light pollution in the home, it is necessary to replace smooth tiles with matte tiles (gloss ≤ 35°). After replacing the specular reflection light of smoot...
