Thin porcelain brick and production method thereof

Abstract

The invention relates to a thin porcelain brick and a production method thereof, wherein the production method comprises the following steps: 1. mixing blank raw materials comprising 4.5 to 5 percent of ball clay, 5 to 6 percent of black mud, 6 to 8 percent of Yichun kaolin, 6 to 10 percent of Beihai kaolin, 6 to 13 percent of Dehua pyrophyllite, 4 to 10 percent of Paishan pyrophyllite, 12 to 16 percent of sodium-potassium feldspar powder, 12 to 15 percent of weathered potassium feldspar, 8 to 15 percent of superfine pottery stone, 8 to 16 percent of sodium-potassium feldspar, 5.5 to 6 percent of Zhuji porcelain sand and 0.8 to 1.3 percent of lignin and lignin derivative; 2. adding water accounting for 50 to 60 percent of the weight of a powder material, 0 to 0.1 percent of polymethyl cellulose sodium (CMC) and 0.1 to 1 percent of sodium tripolyphosphate (STPP), putting into a ball mill, and controlling the ball milling fineness to have 0.5 to 1 percent of sieve residue through a 325-mesh sieve; 3. preparing the powder material containing 5 to 7 percent of water through iron removal, sieving and spray drying of the obtained mud; 4. ageing the powder material for 24 hours, then molding through pressing, and drying at the temperature of 150 to 200 DEG C to enable the water content of a blank to be below 0.3 percent; and 5. placing into a kiln for sintering, wherein the early period time of sintering is 6 to 15 minutes, the high temperature time is 15 to 30 minutes ,and the cooling time is 5 to 10 minutes. In the invention, the thin porcelain brick can be produced under the condition of traditional process equipment, and each item of performance index reaches or exceeds a porcelain brick standard GB/T4100-2006.

Description

technical field [0001] The invention belongs to the field of building ceramic material production, in particular to a thin porcelain brick and a production method thereof. Background technique [0002] The shortage of energy and resources is a century-old problem faced by mankind. The resulting energy and resource crisis has attracted widespread attention from countries around the world to energy saving and consumption reduction technologies and low-carbon economy. As an industry with high resource consumption, high energy consumption and high pollution, the architectural ceramics industry should conform to the trend of the times, develop new technologies for energy saving and consumption reduction, and promote the realization of my country's energy saving, material saving and emission reduction goals. Thinning and reducing production of ceramic tiles is the only way to lead the new development of the ceramic industry with the scientific development concept and comprehensive...

But this method produces the raw material selection of ceramic brick that prior art is generally used for making the various materials of ceramic brick, comprises kaolin and feldspar etc., also adds minerals such as muscovite and sericite, and calcium carbonate and wollastonite, these The compatibility of raw materials is not good during mixing and sintering, and there is still phase separation in the molten state, which is not uniform enough, which affects the overall performance of the product

[0007] CN 100453498C discloses a method for preparing ultra-thin ceramic exterior wall tiles by traditional techniques using clay, binder, kaolin, albite, potassium feldspar, quartz feldspar tailings, and lithium feldspar as raw materials. Bentonite calcined at 700-900oC is used as a binder and lithium feldspar as a flux, which increases the process and cost, and requires additional special equipment
