A kind of ultra-low temperature and low deformation polished glazed brick body and preparation method thereof

Abstract

The invention discloses an ultralow-temperature low-deformation glazed green brick body which consists of a base stock and an additive, wherein the base stock is prepared from the following ingredients: 25-35wt% of Jinqiao limestone, 10-25wt% of Yichun sand, 10-25wt% of Tianhu sand, 3-8wt% of Wanzai sodium sand, 3-5wt% of Jinxi sodium sand, 5-10wt% of lithium chinastone, 2-5wt% of black talc, 0-5wt% of Xingzi sodium sand, 0-5wt% of waste porcelain powder, 5-8wt% of Guangdong black clay, 5-8wt% of Chongqing bauxite chamotte, 3-6wt% of Ji'an white mud, 3-8wt% of Leping bentonite and 2-5wt% of Fuzhou white mud; the additive refers to an organosilicone nano solution with solid content of 40% and accounts for 1-3wt% of the base stock. In addition, the invention also discloses a preparation method of the ultralow-temperature low-deformation glazed green brick body. The preparation method is easily available in raw material and low in price of raw materials, is capable of improving the product performance index, realizing decrease in sintering temperature, enlarging the sintering temperature range, ensuring the product quality and realizing energy consumption and consumption reduction, and is beneficial to promotion in sustainable development of industrial production.

Description

technical field [0001] The invention relates to the technical field of architectural ceramic materials, in particular to a polished glazed brick body and a preparation method thereof. Background technique [0002] Polished glazed brick is a new architectural ceramic product in recent years. After the base glaze is applied to the brick, it is printed, and then a layer of transparent top glaze or transparent convex glaze is applied. After firing, the glazed surface is polished. Polished glazed tiles combine the advantages of polished tiles and antique tiles. The glazed surface is as smooth and bright as polished tiles. Because of its strong three-dimensional pattern, pollution resistance, generous appearance and other characteristics, it is widely used in home furnishing, living, entertainment places and other fields. Glazed tiles belong to one-time firing, which is usually carried out at a firing temperature above 1180°C, and the firing cycle is 60-80 minutes. Therefore, th...

Problems solved by technology

Therefore, the production of prior art glazed tiles not only consumes a large amount of raw materials and fuel, but also has a high production cost and also emits a large amount of CO 2 Exhaust gas, thus exacerbating the global warming effect and causing serious impact on the natural environment, is the main source of CO at home and abroad. 2 One of the hardest-hit industries for exhaust emissions

In addition, the pass rate of glazed tile products in the prior art is generally not high, and the main problem encountered is deformation, including deformation defects such as "water ripples" and "reversed changes"

At present, the existing technology is mainly solved by increasing the firing temperature, which generally needs to be fired at about 1230°C, which undoubtedly further exacerbates the problem of significant energy consumption and does not comply with the national energy-saving and emission-reduction policies. The sustainable development of

In addition, there is also a way to reduce the firing temperature to improve it, but at the same time it also shortens the firing temperature range. Usually the firing temperature range is very narrow and only about 10°C. The product is still easy to deform and brittle, so it is difficult to guarantee in the production process.
