Abstract

The invention relates to a geopolymer chemically-bonded ceramic tile and a preparation method thereof. The geopolymer chemically-bonded ceramic tile is prepared from solid wastes like fly ash, filtered steel and copper slag, and industrial-grade chemical raw materials. The unburned ceramic tile is prepared from, by mass, 60 to 75% of the solid wastes, 19 to 38% of a liquid activator, 1 to 3% of a base-material additive and 1 to 3% of a compound liquid additive by procedures like mixing, sieving and granulating. Due to implementation of a firing-free process, energy conversation and consumption reduction can be realized; pollution is reduced; meanwhile, performances of the geopolymer chemically-bonded ceramic tile can reach national standards of fired ceramic tiles. The geopolymer ceramic tile does not need to introduce calcined kaolin, and after 12 to 48 hours of easy and practicable special maintenance, a ceramic bonded three-dimensional network body is rapidly formed, so the ceramic tile reaches and is superior in a part of performances to the 60-day-age level of similar geopolymer materials; limited mineral resources are not consumed; and energy consumption of calcination is avoided. The geopolymer chemically-bonded ceramic tile provided by the invention can change wastes into treasures, significantly saves energy and reduces consumption, can be used as a novel building material and has extensive application prospects.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a geopolymer chemically bonded ceramic wall and floor tile and a preparation method thereof. Background technique [0002] my country is a big country in the production of architectural ceramics. The annual production of ceramic tiles is about 3 billion square meters, with a mass of 20-24 kilograms per square meter, and about 60-72 million tons of raw material consumption per year. The fuel consumption per square meter is about 1.4-1.5 liters, and the annual fuel consumption is 420-450 million liters. It can be seen that the energy consumption in the production process of traditional architectural ceramics is very huge, and the ceramic tile production process needs to be fired at a high temperature of 1100-1220 ° C, and a large amount of waste gas CO is also emitted during the firing process. 2 . CO 2 It intensifies the greenhouse effect and s...
