Problems solved by technology

Another improved process is the method of soft polishing, which can produce terrazzo tiles with a gloss of about 50 degrees, but there is still a lot of gap with the gloss of terrazzo.
[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 terrazzo refined brick. The preparation method comprises the following processes: preparing a bottom glaze layer, printing decoration patterns, preparing a surface glaze layer, carrying out firing and carrying out polishing, and the terrazzo refined brick is prepared. According to the invention, the terrazzo refined brick with glossiness of 20-30 degrees are prepared through a reasonable surface glaze formula and a polishing technology. The decoration patterns are good in color development, the patterns are clear, and the terrazzo refined brickis more similar to natural terrazzo. Light reflection and light pollution of the terrazzo refined brick is reduced, and the terrazzo refined brick has a wide application prospect. Meanwhile, the surface glaze is applied in a silk-screen printing mode, and screens with different meshes are adopted for carrying out multiple times of printing, so that the concave-convex feeling of a brick surface isstrong, the shade change of pattern lines under natural light conditions are obvious, and the hand feel is realistic.

Description

technical field [0001] The invention belongs to the field of ceramic brick preparation, in particular to a terrazzo brick and a preparation method thereof. Background technique [0002] Antique brick is a kind of brick with antique effect glaze, which is generally stoneware or porcelain. The glazed surface of antique bricks is unique and often has a classical flavor, which is a popular product among consumers. The current main research and development direction of antique bricks is to imitate various types of stone; a product that is popular with consumers is imitation terrazzo products. [0003] Most of the existing terrazzo 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 terrazzo tiles is too high. High, can reach more than 100 degrees, and the glossiness of common terrazzo tiles is quite different. One way to improve is to wax the brick su...
