Abstract
A sterilizing and disinfecting Ag-ion ceramic materials used for decoration of building, brick, bathtub, flushing toilet, life tools and dining utensils to prevent infectious diseases including fowl's influenza, SARS, etc is prepared from raw ceramic body through preparing enamel from non-toxic Ag-ion and ceramic enamel proportionally, and spraying it on the surface of said raw ceramic body.
Description
Technical field
The present invention relates to a kind of silver ions sterilization pottery and manufacture method and purposes, can the porcelain making brick, various ceramic products such as sanitary ware, have the function of permanent automatic sterilizing sterilization.Belong to the ceramic technical field.
Background technology
At present, ceramic product is durable in use with it, any surface finish is attractive in appearance and be subjected to consumers in general's welcome deeply.AT STATION, crowded public areas such as airport, school, hotel, hotel, large-scale meeting-place, ceramic products such as ground, wall, sanitary equipment, toilet are stained with germ easily, need artificial sterilization and disinfection.Through anti-SAR one labour in 2003, people knew sanitarian importance.But how cleaning and cleaning from which aspect just to avoid bacterium to spread unchecked, in general should set about from domestic hygiene and public health aspect, for example: require the public lavatory to accomplish aseptic propagation, begin down to cleaning supplies, material of construction, paint, porcelain tool, wall body and floor, wash clean material etc. from the sanitary equipment in public lavatory, use material with disinfection function.
Because silver can sterilization and is prevented accumulation of bacteria, can prevent that the bacterium diffusion from reaching the purpose that stops disease carrying germ, therefore, people repay examination and use the silver material sterilization, for example with the plastic bottle closure of silver ions, Plastic Bottle, plastic bottle closure pad etc., but only have these products also to be not enough to stop germ to propagate in public places, accomplish to prevent to propagate during bacterium or germ are in public places, using material of construction with sterilizing function (for example automatic sterilization pottery etc.) is a good method.Prior art does not also have the automatic sterilization ceramic product.
Summary of the invention
First purpose of the present invention is for a kind of silver ions sterilization pottery is provided.
Second purpose of the present invention is for a kind of manufacture method of silver ions sterilization pottery is provided.
The 3rd purpose of the present invention is for a kind of purposes of silver ions sterilization pottery is provided.
First purpose of the present invention can reach by taking following measure:
Silver ions sterilization pottery, comprise ceramic body, it is characterized in that: be coated with silver ions glaze layer on the surface of ceramic body, described silver ions glaze layer is made up of nontoxic silver ions and enamel, and the weight percent of described nontoxic silver ions and enamel is 1: 500～1000; Described nontoxic silver ions is powdery silver ions or silver ionized water solution.
First purpose of the present invention can also reach by taking following measure:

The present invention can adopt chelated silver iron.Because chelated silver iron is a kind of nontoxic carbohydrate, to water-soluble stable especially, therefore go for different Ph environment, no matter be acidity or alkaline environment, can both keep the water-soluble material of silver ions state.
Scientific practice proves, as long as contain 50,000,000,000/can eliminate bacterium in the water once the silver ionized water solution of gram.Because therefore no any toxicity of chelated silver iron itself and chemical residual material, meet environmental protection requirement, the product of manufacturing is a Green Product.Owing to be full water-soluble state, its liquid dispersed power is very good, is fit to make various ceramic products.The ceramic product of making has permanent automatic sterilizing sterilizing function.
The water-soluble material of the silver ions of chelating state can be widely used in various finished product, cooperates on the actual life application products.And the silver ionized water of chelating state, more economical and have more low-cost benefit.Nanometer silver generally all between 60～20nm size, each silver ions of the silver ions of chelating state all independently, active high, also than the existing careful manyfold of producing of nanoparticle, even reach 100,000,100 times more than.Therefore utilization ratio ten/height and economic can reduce cost on real rate of utilization 10 times and not wait to 100 times.In goods, save other additive composition at some product, that is to say to reduce cost.
