Problems solved by technology

Another improved process is the method of soft polishing, which can produce marble tiles with a gloss of about 50 degrees, but there is still a lot of gap with the gloss of natural marble.
[0004] On the other hand, most of the anti-skid tiles commonly used at present are provided with wrinkle stripes or concave-convex points on the brick surface to increase the friction between the floor tile surface and the soles of the human body or soles, so as to prevent slipping and falling. Grooves or ridges are set on the surface of the tiles to increase friction, but this method reduces the stain resistance of the tiles; as an improved technology, Chinese application CN201810023625.8 discloses the use of corrosive agents to corrode the tile surface to increase Anti-slip property, but this requires an additional process, which is troublesome, and the surface decoration pattern will be affected when corroded

Abstract

The invention discloses a preparation method of a matte brick. The preparation method comprises the steps: preparing ground glaze, decorative patterns and surface glaze on the surface of a green bodysequentially, then performing drying and firing, performing polishing by using a matte grinding block and a fiber grinding block sequentially, and performing wax so as to obtain the matte brick finished product. The matte brick with a glossiness of 28-36 degrees is prepared through adoption of a reasonable surface glaze formula and a polishing technology, and the decorative patterns have good color and clear patterns, so that the brick is more similar to natural marble; and light reflection and light pollution are reduced through the brick, and broad application prospects are achieved.

Description

technical field [0001] The invention belongs to the field of ceramic tile preparation, in particular to a soft light tile and a preparation method thereof. Background technique [0002] Marble tiles refer to a class of ceramic tile products with realistic texture, color, transparency and texture of natural marble, which have realistic decorative effects of natural marble and superior performance of ceramic tiles. Compared with other ceramic tiles, marble tiles must achieve the realistic effect of natural marble in terms of texture, color, transparency, texture and feel while pursuing superior practical performance. Therefore, it is difficult to improve its practical performance. Much higher than other tile categories. [0003] Most of the existing marble tiles are produced by a production process similar to full-glazing, that is, cloth-pressing-bottom glaze-inkjet printing-top glaze-polishing; but the surface gloss of this type of marble tiles is too high. High, can reach ...
