specific Embodiment 3

[0042] The technical solution of the present invention is: an antibacterial and mildew-proof ceramic of a photocatalyst material, comprising the following components by weight percentage:

[0043]

[0044] The production process for preparing the antibacterial and mildew-proof ceramics of photocatalyst materials includes the following steps in turn: adopting the step-by-step precipitation low-temperature crystallization method, directly using the intermediate product TiCl 4 The anatase nano-TiO2 colloid with high catalytic activity is prepared, the particle size of the nano-particle is less than 10nm, the pH value of the colloid is about 3.0, and the photocatalytic performance is excellent.

[0045] 1) Put the rutile and bamboo charcoal into the heating container according to the above ratio, use a stirring rod to fully mix the rutile and charcoal powder and pass in chlorine gas (Cl 2 ), at a high temperature of 1050°C, TiCl 4 and a flammable gas, it can be seen that the r...

Abstract

The invention provides antibacterial mildew-resistant ceramic of a photocatalyst material. The antibacterial mildew-resistant ceramic of the photocatalyst material contains the following ingredients (by weight): 50-55% of rutile, 35-40% of an efficient inorganic dispersant, 2-8% of a binder and 5-15% of bamboo charcoal. The invention also provides a production technology of the antibacterial mildew-resistant ceramic of the photocatalyst material. The antibacterial mildew-resistant ceramic has the following beneficial effects: 1) the process flow is simple, and the problem that nano-powder is agglomerated during high-temperature calcination by a traditional preparation method and then catalytic activity is reduced is solved; 2) by the use of the efficient inorganic dispersant and the binder, problems such as dispersion of nano-powder, fix bonding and low pH value of colloid are solved; and 3) under irradiation of sunlight and 365nm wavelength UV-light, the product has high catalytic activity, and the defect that ozone which is generated after the use of a 254nm wavelength UV-light source will be harmful to human body is avoided.

Description

technical field [0001] The invention belongs to the field of ceramic tiles, and in particular relates to an antibacterial and mildew-proof ceramic of a photocatalyst material and a production process thereof. Background technique [0002] Photocatalyst [Photocatalyst] is a compound word of light [Photo=Light] + catalyst (catalyst) [catalyst]. Photocatalyst is a general term for photo-semiconductor materials with photocatalytic function represented by nano-scale titanium dioxide. It is currently the most ideal material for indoor environmental pollution control in the world. [0003] Under the irradiation of light, the photocatalyst will produce a photocatalytic reaction similar to photosynthesis, produce free hydroxyl groups and active oxygen with strong oxidation ability, have a strong photoredox function, and can oxidize and decompose various organic compounds and parts Inorganic substances can destroy bacterial cell membranes and solidify virus proteins, and can decompos...
