Wear-resistant anti-skid tile and preparation method thereof

Abstract

The invention discloses a preparation method of a wear-resistant anti-skid tile. The preparation method comprises the following steps: sequentially preparing bottom glaze, protecting glaze, decorationpatterns and surface glaze on the surface of a green body, and then carrying out drying and firing to obtain a wear-resistant anti-skid tile finished product. According to the invention, surface glaze application is carried out at least twice, and the glaze applying amount on the surface of the ceramic tile green body is effectively improved through a mode of applying the protecting glaze, so that wear resistance of the surface of the ceramic tile is improved, and the Moh's hardness of the surface of the ceramic tile provided by the invention is larger than or equal to 7; on the other hand, an anti-skid effect of the ceramic tile is achieved through the special glaze, and the friction coefficient of the ceramic tile provided by the invention is larger than or equal to 0.8.

Description

technical field [0001] The invention belongs to the field of ceramic brick preparation, in particular to a wear-resistant anti-skid 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. In order to enrich the types of antique bricks, the process of applying base glaze-ink-jet printing-applying glaze is currently used for production; ink-jet printing greatly improves the diversity of decorative patterns, making the types of antique bricks more diverse. However, when using inkjet printing decorative patterns, in order to make the decorative effect more obvious, the decorative pattern is usually protected by a transparent topcoat; however, this transparent topcoat often has several problems: 1. This transparent topcoat Generally, the cr...

Problems solved by technology

However, when using inkjet printing decorative patterns, in order to make the decorative effect more obvious, the decorative pattern is usually protected by a transparent topcoat; however, this transparent topcoat often has several problems: 1. This transparent topcoat Generally, the crystal content is low, which makes the hardness of the brick surface too low, and its Mohs hardness is often around 5-6; this makes the antique brick very easy to scratch during installation; it is also easy to wear off the surface glaze after a period of use, grinding Dropping the decorative pattern will greatly affect the decorative effect; 2. The melting temperature of the surface glaze is reduced, making the surface of the antique brick brick too smooth, resulting in a decrease in the anti-skid performance of the brick surface; the risk is high; 3. In the subsequent production process, It is often necessary to polish the glazed surface, which not only causes a waste of raw materials, but also obtains difficult-to-handle polishing slag

[0003] On the other hand, inkjet inks are often mixed with a large amount of solvents in the formula in order to make the pattern adhesion strong, and these solvents will penetrate into the bottom glaze during the firing process, making the printed pattern smudged and reducing the yield
