Embodiment 1

[0031] Antifouling digital protective glaze, including: 240g of burnt gemstone, 20g of muscovite, 350g of quartz stone, 120g of kaolin, 30g of plant ash, 50g of burnt talc, 30g of ball clay, 20g of zeolite, 30g of garnet, 20g of pyrophyllite, Stone 220g, calcium carbonate 15g, barium carbonate 8g, borax 12g and zircon 80g. The plant ash is a product obtained after burning rice stalks.

[0032] The calcium carbonate is modified calcium carbonate. The preparation method of described modified calcium carbonate comprises:

[0033] Calcium carbonate 27g, cationic starch 1.5g, magnesium sulfate 1.5g, carbon powder 0.4g, barium sulfate 0.4g, polyimide 0.6g, epoxy resin 0.4g, polyoxysilane 1g, dimethylformamide 0.15g, Magnesium sulfide 0.4g, sepiolite fiber 0.4g, titanium dioxide 0.5g;

[0034] Add calcium carbonate, cationic starch, magnesium sulfate, carbon powder, barium sulfate, polyimide and stir between 70~80℃, adjust the pH to 10, keep stirring for 1~2h, adjust the pH to 7, ...

Embodiment 2

[0044] Antifouling digital protective glaze, including: 240g of burnt gemstone, 20g of muscovite, 350g of quartz stone, 120g of kaolin, 30g of plant ash, 50g of burnt talc, 30g of ball clay, 20g of zeolite, 30g of garnet, 20g of pyrophyllite, Stone 220g, calcium carbonate 15g, barium carbonate 8g, borax 12g and zircon 80g. The plant ash is a product obtained after burning rice stalks.

[0045] The preparation method of described glaze comprises:

[0046] Mix burnt gemstone, muscovite, quartz stone, kaolin, plant ash, burnt talc, ball clay, zeolite, garnet, pyrophyllite, albite, calcium carbonate, barium carbonate, borax and zircon, and then ball mill to obtain glaze material.

[0047] The glaze is used as the bottom glaze of ceramic tiles, and an intermediate layer and a top glaze are also arranged on the ceramic tiles;

[0048] The middle layer includes 250g of high-temperature frit and 350g of corundum. The high-temperature frit includes the following raw material compon...

experiment example

[0084] With reference to GB / T3810.14, the antifouling ability of the ceramic tiles made by each embodiment was tested. Wherein, the ceramic tiles in each embodiment are ground until the bottom glaze leaks out, and the bottom glaze of the same thickness is ground away.

[0085] Table 1 The antifouling ability of the ceramic tiles of each embodiment

[0086]

[0087] It can be seen from Table 1 that the antifouling digital protective glaze of the present application can also reach the highest antifouling level under the condition of wear.

[0088] The ceramic tile made of the bottom glaze glaze material of Example 1, under the situation of wear and tear, also can reach 5 grades of antifouling, shows that modified calcium carbonate and barium carbonate can promote glaze layer under different firing temperatures. The two-stage exhaust can fully release the gas in the glaze layer, improve the compactness of the glaze layer, and thus improve the antifouling ability of the glaze ...

Abstract

The invention relates to the field of ceramic tile production, provides an antifouling digital protection glaze, and aims to solve the problem of poor antifouling effect of a glaze layer. The antifouling digital protection glaze comprises 11-35 parts by mass of flint clay, 1-5 parts by mass of muscovite, 40-50 parts by mass of quartz stone, 7-20 parts by mass of kaolin, 1-5 parts by mass of plant ash, 4-8 parts by mass of calcined talc, 2-5 parts by mass of ball clay, 1-4 parts by mass of zeolite, 1-6 parts by mass of garnet, 1-5 parts by mass of pyrophyllite, 20-28 parts by mass of albite, 1-3 parts by mass of calcium carbonate, 0.5-1 part by mass of barium carbonate, 1-2 parts by mass of borax and 6-10 parts by mass of zirconite. According to the invention, the formed glaze layer is high in density and good in antifouling effect.

Description

technical field [0001] The invention relates to the field of ceramic tile production, in particular to an antifouling digital protective glaze. Background technique [0002] Ceramic tiles include glazed tiles and porcelain polished tiles. Due to the high gloss of the surface and smooth tile surface, porcelain polished tiles are prone to scratches caused by friction and collision between bricks and bricks during packaging, transportation and construction. , resulting in damage to the surface of the tiles, affecting the quality and appearance of the product. [0003] Moreover, since the microstructure of ceramic materials is composed of crystal phase, glass phase and pores, the final product has a porosity of 5% to 10% (volume). At the same time, the surface of ceramic materials is generally lipophilic. On the surface of the product, especially on the damaged surface, some pollutants penetrate into the open pores due to surface capillary action; in addition, the microscopic u...
