Black inkjet full-polished ceramic tile and preparation method thereof

Abstract

The invention relates to a black inkjet full-polished ceramic tile and a preparation method thereof. The ceramic tile is of a composite layer structure consisting of a green body layer, a ground glazelayer, a pattern layer and a full-polished layer. The preparation method comprises the following steps: (1) ball milling of raw materials: placing ingredients into a ball mill, adding water to perform ball milling on the ingredients to obtain slurry, screening the slurry, and storing the screened slurry into a slurry pool for later use; (2) preparation of a powder compact by spray drying: conveying the slurry to a spray tower, drying the slurry into powder, controlling the moisture of the slurry at 5.8 to 7 percent, and performing dry pressing with a brick press; (3) green body drying: conveying the pressed green body into a drying kiln for drying at a temperature of 180 to 270 DEG C for 40 to 60 minutes; (4) spraying of ground glaze: conveying the ingredients into the ball mill, and adding 42 percent of water to perform ball milling to obtain glaze slurry; and (7) burning: implementing burning at a temperature of 1,080 to 1,150 DEG C for 45 to 60 minutes.

Description

technical field [0001] The invention relates to the field of building ceramics production, in particular to a black ink-jet fully glazed ceramic brick and a preparation method thereof. Background technique [0002] At present, the firing temperature of wall and floor tiles in the building ceramics industry is generally 1180-1240°C, and the firing cycle is 60-90 minutes. High firing temperature and long firing cycle mean high energy consumption and air pollution. Energy saving and emission reduction has always been the direction of the ceramic industry's efforts. Only by reducing the firing temperature and firing cycle can enterprises save more energy and obtain more profit margins. [0003] The stacking of industrial waste has become a serious social and environmental problem. With the decrease of natural mineral reserves, especially today's increasingly stringent environmental protection requirements, how to reasonably arrange and digest these industrial solid wastes to rea...

Problems solved by technology

Another technical problem to be solved by the present invention is to provide a kind of black body ceramic brick that can replace black pigment by using vanadium-titanium industrial tailings and iron removal slag, and add vanadium-titanium tailings and iron removal slag into the ceramic body at the same time It can play the role of flux and greatly reduce the firing temperature of ceramic blanks; the black inkjet full-blown black inkjet can solve the problem of reusing a large amount of iron slag generated in the process of removing iron from local high-iron content raw materials and the solid waste of vanadium and titanium in
