Abstract

The wollastonite tailing reinforced and toughened low-temperature ceramic tile is prepared from the following raw materials in parts by weight: 35 to 45 parts of wollastonite tailings, 18 to 32 partsof low-temperature sand, 2 to 7 parts of medium-temperature sand, 10 to 18 parts of quartz, 2 to 4 parts of talc, 0 to 5 parts of magnesian clay, 2 to 5 parts of bentonite, 0.5 to 3 parts of bauxite,0.5 to 2 parts of zircon sand and 0 to 3 parts. The materials are sintered at the temperature of between 1,120 and 1,150 DEG C to form the ceramic. In addition, the invention further discloses a preparation method of the wollastonite tailing reinforced and toughened low-temperature ceramic tile. The wollastonite tailings are used as a main raw material, and the ceramic tile with high strength andtoughness is obtained while low-temperature sintering is achieved through formula design. According to the method, resource utilization of the wollastonite tailings is achieved, the wollastonite tailings are massively applied to building ceramic production, and the additional value of the tailings is improved. The mechanical strength and toughness of the building ceramic tile are effectively improved, and the building ceramic tile can be further expanded to a large thin plate production technology in the field of building ceramics.

Description

technical field [0001] The invention relates to the technical field of building ceramic materials, in particular to a reinforced and toughened low-temperature ceramic tile with wollastonite tailings as the main raw material and a preparation method thereof. Background technique [0002] The ceramic industry is a high-energy-consumption and high-pollution industry. Taking the construction of ceramic tiles as an example, the annual output of ceramic tiles in my country is about 4 billion square meters. Calculated at 20-24 kg per square meter, the annual consumption of mud and ore materials is 80 million tons to 96 million tons; based on the consumption of 1.4-1.5L of heavy oil per square meter, the annual consumption of heavy oil is 560-600 million liters. Vitrified brick is one of the main products of building ceramics, accounting for about 1 / 6 of the product, that is, the annual output is about 700 million square meters, the consumption of mud and ore materials is about 16 mi...
