Embodiment 1

[0034] The invention provides a method for preparing porous painted pottery microspheres based on ceramic waste. The ceramic raw materials mainly come from waste building ceramics, sanitary ware ceramics, and craft ceramics. The growth of pores is precisely controlled by two pore-forming techniques to obtain pores. The specific operation steps are as follows:

[0035] (1) Preparation of ceramic micropowder: take waste ceramic raw materials (60-80wt%), wash with water, dry, crush, and ball mill until the particle size is less than 500 microns to obtain ceramic micropowder;

[0036] (2) Preparation of mixed slurry: get the above-mentioned ceramic powder, add 10wt% of water glass, 7wt% of calcium carbonate, 5wt% of quartz sand, 5wt% of iron red, 5wt% of styrene-acrylic resin emulsion and water and stir evenly to obtain mixed slurry ;

[0037] (3) Making ceramic powder blanks: putting the above-mentioned mixed slurry in a certain percentage by weight into a mold, applying a press...

Abstract

The invention discloses a preparation method of porous painted pottery microspheres based on ceramic wastes. Ceramic raw materials mainly come from waste house building ceramics, sanitary ware ceramics, craft ceramics and the like. The pore channel growth is accurately regulated and controlled by adopting a twice pore-forming technology. Firstly, primary pore forming is carried out on a ceramic material by a high-temperature foaming agent, high-temperature in-situ coloring of an inorganic pigment is assisted, and then pore channels of the ceramic material are regulated and controlled by caustic alkali etching, so as to obtain the colored light ceramic microspheres with a large porosity range (60-90%) and developed pore channels (micro-nano pore diameter of 70-90%). The porous painted pottery microspheres obtained by the invention can be used in the fields of high-grade reflective thermal insulation materials, sound insulation materials, catalysts, wastewater treatment and the like, andhas good economic value and social benefit.

Description

technical field [0001] The invention relates to the technical field of ceramic resource regeneration, in particular to a porous painted pottery microbead based on ceramic waste and a preparation method thereof. Background technique [0002] The output of ceramics in my country is huge, and the annual output of daily-use ceramics accounts for about 70wt% of the total output of ceramics in my country. % waste rate calculation, the annual production of ceramic wall and floor tiles can reach 1 million tons of waste ceramics. If we consider the waste ceramics produced in other ceramic production, the annual discharge of nano-ceramic waste can reach 1.5 million tons. As we all know, waste ceramics are non-degradable garbage. At present, the disposal of ceramic waste is mainly piled up and landfilled, resulting in a huge waste of land resources. At the same time, heavy metals contained in ceramics penetrate into the soil, which not only pollutes soil resources, but also seriously...
