A kind of full-body porcelain tile combined with inkjet effect and preparation method thereof

Abstract

A whole-body porcelain tile combined with inkjet effect, the ceramic tile is a transparent protective glaze layer / or dry grain layer from top to bottom, a digital printing layer of colored ceramic ink with an area of ​​5% to 100%, and a transparent bottom glaze layer, the green body layer, the transparent bottom glaze layer forms a green body glaze bonding layer with the green body after sintering, the thickness is 0.1-0.5mm, and it is the same color as the green body when viewed from the side section. The invention promotes the color development of the ceramic ink and makes the ink-jet pattern layer and the green body layer have no obvious white line separation layer through the innovation of the transparent bottom glaze formula, so that the overall vision of the digital pattern texture on the surface of the prepared ceramic product and the green body texture The effect is better, especially in the application of decoration after edging and grooving, it is closer to the whole body effect of real imitation stone texture, eliminating the white glaze layer used in traditional methods, which appears white line layer after firing and even ceramic tile products The overall visual effect is not good.

Description

technical field [0001] The invention relates to the field of architectural ceramic tiles, in particular to a full-body porcelain tile combined with an inkjet effect and a preparation method thereof. Background technique [0002] In the decoration of modern buildings, the top-ranking decorative materials are none other than high-grade natural stones with natural patterns and shapes, especially high-grade marbles with fine and attractive textures. However, as people pay more attention to mine resources and environmental protection, in building decoration, people hope to choose environmentally friendly and non-radioactive materials that are in line with the development trend of low-carbon green economy in modern society, and can have a beautiful and durable decoration for home decoration. High-temperature-fired ceramic tile products have gradually become the direction of choice for people because of their wear resistance and hardness, especially ceramic tiles with a whole-body ...

Problems solved by technology

[0003] However, the ceramic tiles in the prior art are represented by ceramic products such as polished glazed tiles and antique tiles with digital patterns printed on the surface. In order to pursue a more vivid effect of ceramic ink patterns after surface polishing, whitening glazes are used as a primer. Because the pattern texture is exquisite, delicate and bright, it is more favored by consumers, but because the bottom glaze layer is milky white after firing, so in the side view effect, there is an interlayer between the bottom blank and the surface pattern. White lines will appear on the side of ceramic tile products, which is unsightly in visual effect and not enough for the overall sense of the body, especially for some products whose surface does not require polishing texture and color and does not pursue bright colors. In some places, the white glaze is exposed on the side layer, which greatly reduces the fidelity of the texture effect of the product restoration material itself, which is not natural enough, and the artificial traces are obvious

[0004] In order to make the overall visual effect of the digital pattern texture on the surface of ceramic products and the body texture more unified, especially in the application of decoration after edging and grooving, the visual effect is closer to the overall effect of the real imitation stone texture, and it is necessary to use as much as possible Ceramic water repellent fully develops its color effect to meet the pre-designed requirements, and the existing technology still needs to be improved in terms of process methods, material formulas and preparation methods
