Problems solved by technology

[0002] In the past ten years, my country's architectural ceramics industry has developed rapidly. The annual output of architectural ceramic products is more than 3 billion square meters. Only in the grinding and polishing process of polished tiles will produce a large amount of solid waste, called ceramic polishing waste. Every year, polishing brick manufacturers spend millions or even tens of millions of dollars to deal with polishing waste, which seriously affects the profitability of enterprises.
At present, most of the treatment of polishing waste is landfill, which has a serious impact on the environment.
The open-air stacking of polishing waste will also pollute the environment, which is not conducive to sustainable development
[0003] At present, the exterior wall decoration of buildings in my country is mainly divided into plastering, veneering and coating, etc. The interior wall decoration can be divided into plastering, veneering, coating and papering. Decorative surface materials are pasted on the outside of the wall insulation material, that is, the integrated treatment of wall insulation and decoration. The decorative materials used mainly include wallpaper, wall covering, wood board, stone, metal plate, ceramic tile, mirror glass, etc. The construction process is various and easy. Cracking, hollowing, etc., and because the materials used for the facing layer and the insulation layer are often different, it is easy to form a cold and heat bridge problem, which affects the service life and energy-saving effect of the insulation and decoration materials.
At the same time, due to the high color requirements of interior and exterior wall decoration materials, paints and paint finishes are often used as commonly used decoration materials at present, most of which contain harmful substances to the human body, and the color will become lighter or even fall off during use, and the service life Short and affect the aesthetics of architectural decoration

Embodiment 1

[0016] After drying the polishing waste residue at 90°C, weigh 4.25kg of polishing waste residue, 0.6kg of purple sand soil, 0.1kg of cobalt blue high-temperature ceramic pigment for billets, and 0.05kg of industrial calcium carbonate, and put the above materials into a ball mill jar for ball milling for 2 hours. Control the volume ratio of the medium ball to the material to be ground to 1:2.5, then take the material out through a 60-mesh sieve, take the part under the sieve and put it into a combined mold (the material of the mold is cordierite mullite), and then put the arranged mold and The materials to be fired are put into the kiln and fired according to the following process: firstly, the temperature is raised from room temperature to 1150°C at a heating rate of 5°C / min, kept for 50 minutes, and then rapidly cooled to 1000°C at a cooling rate of 15°C / min. Keep warm for 20 minutes, and finally cool down to room temperature at a rate of 3°C / min to obtain a blue foamed ceram...

Embodiment 2

[0019] After drying the polishing waste residue at 105°C, weigh 4.5kg of polishing waste residue, 0.4kg of purple sand soil, 0.05kg of coffee red high-temperature ceramic pigment for billets, and 0.05kg of industrial sodium carbonate, and put the above materials into a ball mill tank for ball milling for 2 hours. The volume ratio of the medium ball to the material to be ground is 1:2.5, and then the material is taken out through a 60-mesh sieve, and the part under the sieve is put into a combined mold (the material of the mold is cordierite mullite), and then the arranged mold and the material to be ground The fired material is put into the kiln and fired according to the following process: firstly, the temperature is raised from room temperature to 1200°C at a heating rate of 8°C / min, kept at a temperature of 50 minutes, and then rapidly cooled to 1000°C at a cooling rate of 20°C / min, and kept at a temperature of 1000°C. 30min, and finally cooled to room temperature at a rate ...

Embodiment 3

[0022] After drying the polishing waste residue at 110°C, weigh 4.4kg of polishing waste residue, 0.4kg of purple sand soil, 0.15kg of bright yellow high-temperature ceramic pigment for billets, and 0.05kg of industrial calcium carbonate. The volume ratio of the medium ball to the material to be ground is 1:2.5, and then the material is taken out through a 60-mesh sieve, and the part under the sieve is put into a combined mold (the material of the mold is cordierite mullite), and then the arranged mold and the material to be ground The fired material is put into the kiln and fired according to the following process: firstly, the temperature is raised from room temperature to 1200°C at a heating rate of 10°C / min, kept at a temperature of 50 minutes, and then rapidly cooled to 1000°C at a cooling rate of 18°C / min, and kept at a temperature of 1000°C. 30min, and finally cool down to room temperature at a rate of 4°C / min to obtain a light yellow foamed ceramic plate.

Abstract

The invention relates to a preparation method for a colored foamed ceramic sheet material by utilizing polished waste slag. The method mainly solves the problem of hazard to the environment due to waste material discharge of ceramic production enterprises which mainly produce polished tiles. The method prepares the colored foamed ceramic sheet material capable of being used as a decorative material for interior and exterior walls by using the polished waste slag as a raw material through addition of a certain amount of auxiliary materials like purple clay, ceramic pigment and a foaming agent, ball milling and mixing treatment, mold filling and shaping, and high-temperature sintering at about 1200 DEG C, wherein the material has stable and adjustable color, a volume weight of 0.3 to 0.45 g/cm3 and a thermal conductivity of 0.06 to 0.12 w/(m/k). The preparation method provided by the invention has characteristics like low cost, high additional value, good durability, convenient construction and good fireproof performance, realizes integration of environmental friendliness and beautiful appearance of a decorative sheet material used for building, greatly simplifies construction process, and can be extensively applied in the field of decorative materials for interior and exterior walls.
