Description
Technical field
The invention belongs to ceramic processing technique field, it is related to a kind of antibacterial and mouldproof ceramic tile and preparation method thereof.
Background technique
Ceramic tile is a kind of important ceramic, mainly with metal oxide and half-metal oxide ground, mixing,
The building or ornament materials that the processes such as compacting, glazing, sintering obtain, when it is applied in the places such as hospital, dining room and family
When the occasions such as kitchen, toilet, traditional ceramic tile does not have the function of decontamination, deodorization, sterilization, self-cleaning, often to human health
Harm is brought, therefore, there is antibacterial, mould proof, self-cleaning function ceramic tile to come into being.
Antibiotic ceramic tile is the product for combining ceramic technology with antimicrobial technology, it keep ceramic original function and
While decorative effect, disinfection, sterilization, mould proof function are increased, there is widely application.Existing antibiotic ceramic tile is general
It is silver-colored based nano-material to be added on the basis of common ceramic tile, and play the antimicrobial nano material on the mainly surface layer of antibacterial action,
It is unable to give full play its effect if being added in ceramic raw material, if but be directly added to surface layer, it is easy with using the time
Extend and gradually falls off and lose antibacterial functions；Meanwhile when nanometer silver material is used alone, it is easy to happen agglomeration, antibacterial
It is ineffective.In this regard, researchers also make a variety of corrective measures.
CN 102765930A discloses a kind of manufacturing method of antibiotic ceramic tile, using kaolin, feldspar, china clay as raw material system
Base, the one side of ceramic tile blank mark out the latticed wire casing formed by horizontal, vertical line square crossing, nano silver are placed in wire casing
Silk, is then made glaze slip with diatomite powder, diamond stone powder, metallic silver powder and color powder, and to ceramic tile blank glazing, then
Fired formation antibiotic ceramic tile, silver-colored usage amount is big in this method, higher cost, and is easy to fall off, and application prospect is limited.CN
It includes idiosome, ground coat enamel and face that 109293338A, which discloses a kind of negative ion antibiotic ceramic tile and its production technology, the antibiotic ceramic tile,

It applies since silicon dioxide gel is not used in example 5, the combination decrease of nano zine oxide and glaze, the persistence of antibacterial is slightly
Difference；The usage ratio of silver oxide and terbium oxide is bigger than normal in embodiment 6, not only cost is caused to improve, and silver oxide more than needed without
Method is fixed and is easy to run off, and is unfavorable for the raising of anti-microbial property instead；The usage ratio of silver oxide and terbium oxide is inclined in embodiment 7
Small, antibacterial effect and persistence are slightly worse；And rare-earth oxide is not used in comparative example 1, silver oxide can not be abundant
It is fixed in glaze, is easy to run off in use process, cause the persistence of antibacterial poor；Antibacterial agent conduct is not used in comparative example 2
Photochemical catalyst can not provide sufficient free electron and form the strong negative valency silver ion of bactericidal properties, can not also form hydroxyl radical free radical
Etc. antibacterials group, cause its antibacterial effect poor.
The Applicant declares that the present invention is explained by the above embodiments method detailed of the invention, but the present invention not office
Be limited to above-mentioned method detailed, that is, do not mean that the invention must rely on the above detailed methods to implement.Technical field
Technical staff it will be clearly understood that any improvement in the present invention, equivalence replacement and auxiliary element to each raw material of product of the present invention
Addition, selection of concrete mode etc., all of which fall within the scope of protection and disclosure of the present invention.
