[0023] In parts by weight, take 20 parts of kaolin, 25 parts of montmorillonite, 20 parts of bentonite and 60 parts of water to mix to obtain pottery clay slurry, and mix pottery clay slurry with egg white and activated sludge in a mass ratio of 10:1:1 After mixing, the fermentation substrate is obtained; put the fermentation substrate into the fermenter, seal the fermenter, and ferment for 10 days at 25°C. And mass fraction is that 30% sodium carboxymethyl cellulose solution is 50:1:1:8 to get ceramic base material after mixing by mass ratio; The ceramic base material that will obtain is injected in the stainless steel mould, with the pressure holding of 5MPa with sample press Press for 20 minutes to obtain a ceramic green body. Put the ceramic green body into an oven and dry it at a temperature of 105°C for 1 hour. After drying, a dry green body is obtained; The temperature was raised to 800°C at a rate of min, and the heat preservation and pre-fired for 1 hour. After the pr...

[0025] In parts by weight, take by weighing 23 parts of kaolin, 28 parts of montmorillonite, 25 parts of bentonite and 65 parts of water to mix to obtain pottery clay slurry, and mix pottery clay slurry with egg white and activated sludge in a mass ratio of 10:1:1 After mixing, the fermentation substrate is obtained; put the fermentation substrate into a fermenter, seal the fermenter, and ferment for 11 days at 30°C. And mass fraction is that 30% sodium carboxymethyl cellulose solution is 50:1:1:8 after mixing by mass ratio to get ceramic base material; Press for 23 minutes to obtain a ceramic green body. Put the ceramic green body into an oven and dry it at a temperature of 108°C for 1 hour. After drying, a dry green body is obtained; The temperature was raised to 850°C at a rate of min, and the heat preservation and pre-fired for 2 hours. After the pre-fired, the pre-fired ceramics were obtained. The tetrabutyl titanate and absolute ethanol were mixed at a mass ratio of 1:3 ...

[0027]In parts by weight, take 25 parts of kaolin, 30 parts of montmorillonite, 30 parts of bentonite and 70 parts of water to mix to obtain pottery clay slurry, and mix pottery clay slurry with egg white and activated sludge in a mass ratio of 10:1:1 After mixing, the fermentation substrate is obtained; put the fermentation substrate into a fermenter, seal the fermenter, and ferment for 12 days at 35°C. And mass fraction is that 30% sodium carboxymethyl cellulose solution mixes by mass ratio 50:1:1:8 to get ceramic base material; The ceramic base material that will obtain is injected in the stainless steel mould, with the pressure holding of 8MPa with sample press Press for 30 minutes to obtain a ceramic green body. Put the ceramic green body into an oven first, and dry it at a temperature of 110°C for 2 hours. After drying, a dry green body is obtained; The temperature was raised to 900°C at a rate of min, and the heat preservation and pre-fired for 2 hours. After the pre-fi...

Abstract

The invention relates to a preparation method of antifouling self-cleaning ceramic and belongs to the technical field of ceramic preparation. The method includes steps of: mixing a plurality types ofpottery clay, as raw materials, with water to prepare pottery clay slurry; mixing the pottery clay slurry with egg white and active sludge for fermentation; mixing the fermented product, potassium thiocyanate, sodium pyrophosphate and sodium carboxymethylcellulose to obtain a ceramic base material; injecting the ceramic base material into a mould and performing compression moulding, and sinteringthe product to obtain pre-sintered ceramic; finally performing impregnation to the pre-sintered ceramic with a tetrabutyl titanate and ethanol mixture liquid, adding water and performing an ultrasonicreaction; and calcining the product to obtain the antifouling self-cleaning ceramic. The ceramic has great antifouling performance and has extensive application prospect.

Description

technical field [0001] The invention relates to a method for preparing antifouling self-cleaning ceramics, belonging to the technical field of ceramic preparation. Background technique [0002] Since the microstructure of ceramic materials is composed of crystal phase, glass phase and pores, the final product has a porosity of 5% to 10% (volume). Among the open pores; in addition, the microscopic unevenness of the ceramic surface also leads to its adhesion to pollutants. Studies have found that pollutants are basically composed of soluble colored inorganic or organic substances in water, usually acidic or alkaline, such as sewage, tea, dust, ink and organic oil in daily life, which make the ceramic surface polluted and difficult to clean. Clear, affecting cleanliness and aesthetics. The accumulated oil will become a breeding ground for bacteria. If it is not cleaned, the ceramics in the living room will become the source of virus and bacteria infection. With the wide use o...
