Embodiment 1

[0025] The invention claims to protect a preparation process of a 4-8 degree soft surface wear-resistant retro brick, which includes the following steps:

[0026] (1) Glaze preparation and processing: raw material collection, crushing, batching by forklift, wet ball milling, sieving and iron removal, spray milling, aging, molding and drying, the ball milling time is 8-12 hours, and the glaze after ball milling The fineness of the iron is controlled at 2801-320 mesh, and the 130-mesh sieve is used to remove iron twice, and then stale for one day at room temperature;

[0027] (2) Applying the bottom glaze, putting the bottom glaze into the glazing device, and using the glazing device to cover the surface of the obtained bottom body with the bottom glaze to obtain the glaze body.

[0028] (3) Ink-jet printing, printing ceramic ink on the base glaze according to the pre-prepared color pattern by an ink-jet printer to form a decorative pattern.

[0029] (4) Spray the surface glaze...

Embodiment 2

[0037] For the preparation process in Example 1, it adopts multi-stage polishing, and its multi-stage polishing specifically includes three steps. In step 1, an abrasive tool with elastic characteristics is used for polishing, wherein the polishing medium of the elastic abrasive tool is Resin-bonded abrasives are used, the abrasive fineness is 245-330 mesh, in step 2, the abrasive is used as the grinding tool for polishing, and the abrasive fineness of the abrasive is 245-320 mesh, and the abrasive sheet is used in the step 3 as The abrasive tool is polished, and the abrasive fineness of the abrasive sheet is 480-520 mesh.

[0038] Further, bristles for polishing are provided on the abrasive brush, and the bristles are made of hard plastic and abrasive materials.

[0039] Further, the polishing medium of the abrasive sheet is abrasive material combined with fibers.

[0040] As a preferred embodiment in Example 2, it is intended to further optimize the specific abrasive finene...

Embodiment 3

[0042]Compared with the preparation process in the above-mentioned examples, the best plan for spraying the top glaze in step (4) is to spray 52g / m2 water on the surface of the bottom glaze with decorative patterns after drying to reach the first spraying time. Slurry position, according to the amount of 420g / m2 waterfall type slurry a, after about 15 seconds of transmission time, reach the second level of slurry level, according to the amount of 750g / m2 waterfall type slurry b.

[0043] For the firing quality control in the present invention, the specific surface temperature can be set as: 1110°C, 1125°C, 1160°C, 1186°C, 1200°C, 1210°C, 1210°C, 1109°C, 770°C; corresponding to the above surface temperature setting, The bottom temperature in the present invention can be set as: 1080°C, 1122°C, 1142°C, 1162°C, 1185°C, 1109°C, 1192°C / 860°C, 584°C; meanwhile, the firing cycle set in the present invention is 61 minutes.

[0044] The present invention has following beneficial effect...

Abstract

The invention relates to a preparation process of a wear-resistant vintage brick with a 4-8-degree soft surface. The preparation process comprises the following steps: (1) preparation and processing of glaze; (2) application of ground glaze: placing the ground glaze into a glaze spraying device, utilizing the glaze spraying device to cover the surface of an obtained bottom blank with the ground glaze and obtaining a glaze blank; (3) ink-jet printing: printing ceramic ink on the ground glaze by an ink-jet printer according to a color pattern prepared in advance and forming a decorative pattern;(4) spraying of cover glaze: spraying on the dried ground glaze surface with the decorative pattern by 50-60g/m<2> of water to reach a first-time slurry spraying position, carrying out waterfall-typespraying of cover slurry a according to a dosage of 400-450g/m<2>, reaching a second-time slurry spraying position after a conveying time of about 15 seconds, and carrying out waterfall-type sprayingof cover slurry b according to a dosage of 500-900g/m<2>; secondary drying: conveying the blank body sprayed with cover slurry twice into a drying kiln with the temperature of 120-220 DEG C, whereindrying period is 40 minutes; finally, carrying out firing, multistage polishing and graded package.

Description

technical field [0001] The invention belongs to the field of ceramic building materials, and in particular relates to a preparation process of a 4-8 degree soft surface wear-resistant retro brick. Background technique [0002] Ceramic tiles are acid and alkali resistant porcelain or stone objects formed by grinding, mixing, pressing, glazing and sintering of refractory metal oxides and semi-metal oxides. They are called retro bricks. However, retro The development time of bricks in the Chinese market is still short. Taiwanese businessmen first brought this term into mainland China, and antique brick enterprises sprung up like mushrooms after rain. In the context of fierce competition in the market, ceramic enterprises and technicians, in addition to innovating in product design, also pay more attention to product texture, surface hardness and surface flatness of products, and strive to reduce production costs. The color and appearance of antique bricks emphatically reflect ...
