Abstract

The invention discloses an ultrathin ultra-white talc constructional ceramic tile and a manufacturing method thereof. A ceramic body comprises the following chemical components by weight: 50 to 62% of SiO2, 15 to 30% of Al2O3, 5 to 17% of MgO, 2 to 10% of K2O, 2 to 5% of Na2O and 1 to 10% of CaO. The ceramic tile comprises the following raw materials by weight: 20 to 50% of talc, 10 to 40% of feldspar, 15 to 30% of kaolin, 0 to 5% of bentonite, 0 to 5% of quartz powder and 2 to 15% of alumina powder. The invention has the following beneficial effects: the ultrathin ultra-white talc constructional ceramic tile has good formability; through changing of a formula, the purposes of ultra-whiteness and ultrathinness are realized, and the thickness of the tile is only 4.8 mm, half of the thickness of a traditional tile; resources of raw materials are saved, and comprehensive energy consumption is reduced; the load of a building is effectively reduced; and directed at high-rise buildings, the ceramic tile has more obvious effect and can prolong the service life of the buildings.

Description

technical field [0001] The invention belongs to the technical field of building ceramics, and in particular relates to an ultra-thin talcum ultra-white building ceramic brick and a manufacturing method thereof. Background technique [0002] Recently, with the rapid development of my country's society and economy, the building ceramics industry has also developed rapidly, and its role in the national economy has been significantly improved. The output of ceramic tiles has been ranked first in the world for many years in a row, but at the same time there are contradictions between development and resources, energy, and waste emissions. The thinning of ceramic tiles is one of the important ways for the building ceramics industry to achieve resource conservation, energy conservation and emission reduction. At the same time, with the significant improvement of people's material living standards, people's demand for high-grade architectural ceramic tiles is increasing day by day....
