Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of ceramic tiles, and particularly relates to a laser engraving device and a preparation method of anti-slip glaze ceramic tiles with anti-fake function. BACKGROUND

[0002] The anti-slip performance of ceramic tiles refers to the ability to reduce the risk of sliding between pedestrians and the surface of ceramic tiles on the ground. With the increasing safety awareness of consumers, anti-slip ceramic tiles have gradually become the mainstream of the building materials market. However, most of the current anti-slip ceramic tiles use concave-convex molds, fused block dry particles, special materials, and high-temperature printed glazes to make the surface of ceramic tiles uneven, thereby achieving the anti-slip effect. Although such products have excellent anti-slip performance, they have the disadvantages of rough surface and easy dirt accumulation and difficult cleaning. In addition, with the fierce competition in the building materials market and the serious homogenization of industry products, some unscrupulous manufacturers prevent brand enterprises from obtaining improper profits by imitating the patterns and trademarks of the products of brand enterprises, which not only harms consumers but also hinders the progress of the industry and the protection of technological innovation of brand enterprises. In view of this, ceramic industry technical personnel have developed related anti-slip and anti-fake technologies for glaze ceramic tiles.

[0003] Chinese Patent CN111002446B discloses a ceramic polishing anti-slip wax, a fine anti-slip and anti-fouling full-polished glaze ceramic tile, and a preparation method thereof. The method mainly applies an anti-slip wax with corrosion performance to the surface of the ceramic tile to destroy the crystal structure of the glaze layer and form fine depressions on the surface of the tile, thereby improving the friction coefficient of the ceramic tile. Although the ceramic tile produced by the method has certain anti-slip effect, it has the disadvantages of non-environmental protection of the anti-slip wax, difficulty in controlling the anti-slip value, poor corrosion resistance of the glaze surface, and easy dirt accumulation on the glaze surface after a period of use, which is not easy to clean. Chinese Patent CN1095516836B discloses a preparation method of an anti-slip ceramic tile, which has the following process steps: ① printing a decorative pattern on the glaze of the ceramic tile to form a decorative pattern layer; ② spraying ink on the decorative pattern layer to form a push-off ink layer, wherein the push-off ink is in the form of dots and is uniformly distributed on the decorative pattern layer; ③ applying a glaze on the push-off ink layer and firing it in a kiln to obtain a semi-finished product; and ④ polishing and post-processing the semi-finished product to obtain a finished product. The product has an interaction force with the shoe sole through the opening holes on the tile surface, thereby increasing the friction coefficient and achieving the anti-slip effect. However, the functional push-off ink is expensive, and large-scale use of the push-off ink increases the production cost. Moreover, the anti-slip performance of the anti-slip ceramic tile prepared by the process can meet the use needs in the dry state, but the friction coefficient is generally low in the wet state, the anti-slip effect is relatively limited, and the product cannot be widely used in public places.

[0004] Regarding the anti-counterfeiting technology of ceramic tiles, Chinese patent CN108623332A discloses a production method of ceramic tiles with fluorescent anti-counterfeiting marks. A base glaze layer is first sprayed on the body of the ceramic tile, then a layer of transparent glaze paste is sprayed, and then a layer of fluorescent powder with patterns is printed. A layer of transparent glaze paste is then sprayed, and after firing, a ceramic tile structure is formed, which is composed of a base layer, a base glaze layer, a base glass layer, a fluorescent powder layer, and a surface glass layer in sequence. The ceramic tile obtained by this method can be seen under a purple light in a dark environment, but the patterns of the fluorescent layer on the tile can be seen under natural light, which affects the decorative effect of the ceramic tile itself.
