preparation example Construction

[0043] The glaze preparation method of the above-mentioned matte antifouling glaze comprises the following steps:

[0044] (1), adding the raw materials of glaze A into a ball mill according to the ratio, mixing sodium hydroxymethyl cellulose, sodium tripolyphosphate and water into the ball mill for ball milling, and obtaining glaze A;

[0045] (2), adding the raw materials of glaze B into a ball mill according to the ratio, mixing sodium hydroxymethyl cellulose, sodium tripolyphosphate and water into a ball mill for ball milling, and obtaining glaze B;

[0046] (3) Mix glaze slurry A and glaze slurry B at a volume ratio of 1: (3-4) to obtain glaze slurry C, which is the glaze slurry of the matte antifouling glaze. It is forbidden to ball-mill glaze slurry C again.

[0047] The glaze slurry of the matte antifouling glaze obtained by the above-mentioned glaze slurry preparation method has good homogeneity. Glaze A and glaze B are mixed to form glaze C, which ensures that glaze ...

Embodiment

[0073] Example group B is matte antifouling tiles

[0074] The matte antifouling tiles of Examples B1-B6 all include a glazed layer on the surface of the brick layer, the glazed layer is fired from the glaze slurry C prepared in one of Embodiments A1-A6, and the gloss of the glazed layer is 2 ~3 degrees. The preparation method of the matte antifouling ceramic tile is as follows:

[0075] (1), prepare adobe;

[0076] (2) Spread the glaze slurry C on the surface of the brick adobe, and the amount of glaze applied is 500-670g / m 2 ;

[0077] (3) Dry the adobe coated with glaze slurry C, and then put it into a kiln for firing at a firing temperature of 1192-1205° C. and a firing time of 50-60 minutes.

[0078] The glaze slurry C of the matte antifouling tiles of Examples B1-B6 and its preparation process parameters are shown in Table 4.

Abstract

The invention discloses matte antifouling glaze. The matte antifouling glaze is prepared from glaze A and glaze B; calcined talc, nepheline and alpha-spodumene are used as raw materials of the glaze Ato adjust the firing temperature of the glaze, and the glaze generates a liquid phase locally at 950-1050 DEG C; and the glaze B is formed by using barium carbonate, calcite and zirconia to adjust aglass phase. Correspondingly, the invention further discloses a glaze preparing method of the matte antifouling glaze, a matte antifouling ceramic tile and a preparing method of the ceramic block. Inthe firing process of the glaze, when the temperature reaches 950-1050 DEG C, bubbles are generated during discharging of carbonate substances, organic matter and the like in the glaze, at the moment,the liquid phase enters bubble gaps to fill the bubble gaps, thus when the glaze is sintered at 1192-1205 DEG C, the glaze is denser, the number of air holes is minimum, and the glaze surface has a great antifouling effect.

Description

technical field [0001] The invention relates to the technical field of ceramic tiles, in particular to a method for preparing matte antifouling glaze and glaze slurry, ceramic tiles and the preparation method. Background technique [0002] With the improvement of people's living standards, the quality requirements of products are getting higher and higher. Based on the popular imitation marble or wood effect of ceramic tile products, in order to pursue a more realistic effect and touch, the design of ceramic tile products will have a relatively low gloss and rough surface texture. The surface gloss of ceramic tile products is low and rough. , along with anti-fouling problems have arisen. If the anti-fouling effect of the product is poor, after the user uses it for a period of time, a lot of dirt will remain on the surface of the product, which will affect the visual sense and the user experience is not good. [0003] The anti-fouling glaze tiles currently on the market: (s...
