Embodiment 1

[0076] Preparation of ceramic tiles:

[0077] 1. Using the method of spraying glaze, the primer glaze slurry is applied to the green ceramic tile to obtain the primer glaze layer. Glazing process parameters: the specific gravity of the bottom glaze slurry is 1.75g / mL, the flow rate is 18s, and the glazing amount is 520g / m2 2 .

[0078] Wherein, by weight, the chemical composition of the bottom glaze includes:

[0079] SiO 2 49.91 parts, Al 2 O 3 19.67 parts, Fe 2 O 3 0.19 copies, K 2 O 1.16 parts, Na 2 3.52 parts of O, 7.55 parts of CaO, 2.36 parts of MgO, ZrO 2 12.39 parts, BaO 3.25 parts.

[0080] The bottom glaze slurry is prepared by the following steps:

[0081] After mixing the bottom glaze of the above chemical composition, 0.15 part of sodium carboxymethyl cellulose, 0.25 part of sodium tripolyphosphate and a certain amount of water, after ball milling for 12 hours, then using a 120-mesh sieve to filter and remove iron to obtain a bottom Glaze slurry, t...

Embodiment 2

[0090] The only difference from Example 1 is that when the decorative pattern is printed by inkjet, the ink is brown ink with a gray value of 100%.

Embodiment 3

[0092] The only difference from Example 1 is that when the decorative pattern is printed by inkjet, the ink is an orange ink with a gray value of 100%.

Abstract

The invention discloses a color-stabilizing protective glaze, a ceramic tile and a preparation method of the color-stabilizing protective glaze, and the color-stabilizing protective glaze is prepared from the following raw materials in parts by weight: 15-24 parts of calcined soil, 8-17 parts of wollastonite, 10-35 parts of high-temperature frit, 20-30 parts of matte transparent frit and 10-30 parts of low-temperature transparent frit. The matting temperature of the protective glaze is adjusted by adding the calcined soil, the firing temperature is reduced and the firing time is shortened by adding the wollastonite, and meanwhile, the high-temperature frit, the matte transparent frit and the low-temperature transparent frit are introduced in a high proportion, so that the melting firing temperature of the glaze is expanded, the effect deviation of the glaze under different firing systems is small, and the service life of the glaze is prolonged. And the color development stability of the ink-jet ink under different conditions is ensured. The color-stabilizing protective glaze provided by the invention not only can play a role in protecting a decorative pattern layer and prolonging the service life, but also can stabilize the natural color of decorative ink, and the color of a decorative pattern is not influenced by the change of using process parameters, so that the color-stabilizing protective glaze is beneficial to repeated production on line.

Description

technical field [0001] The invention relates to the field of ceramic tiles, in particular to a color-stabilizing protective glaze, a ceramic tile and a preparation method thereof. Background technique [0002] In recent years, ceramic tiles tend to develop towards large and thin slate and thick and hard granite products. These products also put forward higher requirements for pattern decoration on the surface of ceramic tiles, and digital inkjet decoration is the current State-of-the-art decoration technology. Although inkjet printing has the advantages of clear pattern, fast board alignment, and flexible use, inkjet products are more prone to the problem of scratching on the brick surface in the later use process. At present, inkjet products in the industry generally add protective glaze technology after inkjet decoration. The main purpose of applying protective glaze after inkjet is to protect the decorative pattern layer and prolong the service time of the decorative pa...
