Melting at high temperature for 2.5 hours to form a melt, quenching, crushing, and drying to obtain a fully glazed frit.

[0027] Weigh 71 kg of glaze frit for ceramic tiles, 0.3 kg of sodium tripolyphosphate, 0.1 kg of sodium carboxymethyl cellulose, and 29 kg of water. After mixing evenly, ball mill until 100 g of slurry is passed through a 325-mesh sieve. 0.1~0.2%, and adjust the specific gravity to 1.84 to get full glaze glaze slurry.

[0028] Taking a tile of 300mm×600mm as an example, pour 100g of bottom glaze, top glaze, pattern glaze, and full glaze glaze slurry on the body layer 1 to form bottom glaze layer 2, top glaze layer 3, and pattern glaze layer. 4 and the full glaze layer 5, the thickness of the full glaze layer 5 is 0.15mm. Enter the kiln for sintering at 1120°C, take it...

Embodiment 3

[0030] Weigh 33 kg of potassium feldspar, 15 kg of calcite, 5 kg of calcined talc, 8 kg of zinc oxide, 3 kg of barium carbonate, 7 kg of boric acid, 1 kg of alumina, and 28 kg of quartz. Melting at high temperature for 3 hours to form a melt, quenching, crushing, and drying to obtain a fully glazed frit.

Abstract

The invention discloses a fully glazed ceramic chip and a preparation method of the fully glazed ceramic chip. The fully glazed ceramic chip comprises a green body layer, a ground coat layer, an overglazed layer and a fancy glaze layer. A fully glazed layer is arranged on the surface of the fancy glaze layer. The fully glazed layer comprises 64-71% of fully glazed smelted blocks, 0-7% of clinker, 25-32% of water, and 0.1-0.5% of auxiliary materials by weight percentage, wherein materials used by the fully glazed smelted blocks comprise potash feldspar, calcite, burned talc, zinc oxide, boronic acid, barium carbonate, aluminum oxide and quartz, and the clinker is qidao clay or kaolin. The fully glazed ceramic chip provided by the invention is used for ceramic chip decoration, and the glazing effect of the ceramic chip is good, the transparency of the enamel layer and the evenness are high, and the ceramic chip polished is bright so as to represent the clear texture level and rich texture of pictures under glazes, and the brick deformation is small, the thermal shock resistance is good, the mirror finish effect is good, and the transparent texture is excellent.

Description

technical field [0001] The invention relates to the field of building ceramics, in particular to a fully glazed porcelain piece and a preparation method thereof. Background technique [0002] In the past ten years, the construction and sanitary ceramics industry has developed rapidly, and the ceramic production technology and products are changing with each passing day. Antique bricks with smooth surface and good gloss, as well as antique bricks with rich and varied designs and very personalized features, have achieved unprecedented popularity in recent years, and the city is full of fully glazed products. . However, the field of ceramic tiles has not made great progress in the past ten years, which is in sharp contrast with the field of antique tiles. In addition to upgrading from screen printing to rubber roller printing and then upgrading to the current hot inkjet printing in terms of decoration techniques, its glazed surface The effect has not been fundamentally improv...
