Abstract
The invention relates to a titanium dioxide ceramic and a preparation method thereof and belongs to the technical field of ceramic machining. The preparation method of the titanium dioxide ceramic comprises the following steps: sputtering metallic titanium on the surface of ceramic by utilizing existing magnetron sputtering coating equipment, naturally oxidizing on the surface of the ceramic to generate a TiO2 thin film, then baking and drying under infrared lights, then putting the ceramic into a furnace to be subjected to heat treatment, and cooling, so that the titanium dioxide ceramic is obtained. The titanium dioxide ceramic prepared by adopting the preparation method provided by the invention can decompose organic matters in the air and catalyze oxygen in the air into negative oxygen ions, so that the air is fresh, and the aim of purifying the air is achieved; meanwhile, bacteria on the surface of the ceramic and bacteria in the air can be killed at the same time, and the cleaning effect can be achieved.
Description
Technical field
The present invention relates to a kind of pottery and preparation method thereof, be specifically related to a kind of titanium dioxide ceramic and preparation method thereof, belong to ceramic processing technique field.
Background technology
Environmental protection and energy is the problem that the current whole world is all being concerned about; along with the raising to environmental protection requirement; and bring the understanding of harm to aggravate environmental degradation to human lives; people have environmental-protection function to use and utilize natural condition to reach automatic cleaning effect; the requirement of the green construction material can beautified the environment again is more and more urgent; and the appearance of self-cleaning ceramic, exactly meet this wonderful dream of people.
Titanium dioxide (Titamium Dioxide), has another name called titanium dioxide, is a kind of odorless tasteless white powder of quality softness, opacifying power and strong coloring force, molten point 1560 ~ 1580 DEG C.Water insoluble, diluted mineral acid, organic solvent, oil; Be slightly soluble in alkali, be dissolved in the vitriol oil.At present, the specific surface area utilizing titanium dioxide huge, surperficial many meso-hole structures and superpower adsorptive power and unusual physicochemical property, the antibacterial powder of efficient, lasting, high temperature resistant, the broad-spectrum antimicrobial developed, represents bacterial classification to Gram-positive and Gram-negative represents the antibacterial ability of bacterial classification clearly; And the intestinal bacteria can killed completely in water, and can keep reaching the flora of not multiplying in 90 days and making new advances.Because of its good weathering resistance, water tolerance, inhibited from yellowing; Nontoxicity, nonirritant; And there is the feature of high stability, high transparent, high reactivity and polymolecularity; As a kind of antiseptic-germicide, be widely used in food, washing composition, textiles, enamel, pottery, welding electrode, chemical fibre and makeup, the application particularly in environmental protection and treatment presents scene of flourishing life.
Because titanic oxide material has the features such as chemical stability is good, sintering temperature is low, erosion resistance is strong, very strong anti-microbial property is still kept after Beijing enamel, that other anti-biotic material is too far behind to catch up, this just can meet clean pottery and utilize the natural condition such as sunlight, air, rainwater, automatically keeps the requirement that ceramic surface is clean; Buildings is high-rise especially, adopt self-cleaning ceramic greatly can reduce cleaning cost, and sanitising agent is to the pollution of environment; And the TiO2 film that ceramic surface plates can also decomposite negative oxygen ion under ultraviolet light conditions, kill the bacterium in the bacterium of ceramic surface and air, play the effect of environment purification, thus become the focus of research at present.Titanium dioxide ceramic has wide practical use, mainly in Operation theatre, the ward of hospital, and sanitary ceramic ware, the aspects such as exposed wall glazed tile.
Chinese invention " self-cleaning ceramic ", its technical scheme of application number CN02113349.2 coats the complex sol film of TiO2 and SnO2, fire, prepared complex sol membrane process is complicated again, with the addition of the nontoxicity that organic solvent then cannot ensure pottery.Chinese invention " a kind of titanium oxide ceramics and preparation method thereof ", application number CN201110367021.3 fires after the material of each component in proportion ball milling, mixing, obtains a kind of preparation method improving electric conductivity, high temperature resistant, wear-resisting titanium oxide ceramics.
Summary of the invention
The object of this invention is to provide a kind of titanium dioxide ceramic and preparation method thereof, this pottery can utilize natural condition to reach automatic cleaning effect, can kill the bacterium in the bacterium of ceramic surface and air simultaneously, play the effect of environment purification.
In order to solve the problem, the technical solution adopted in the present invention is:
1. titanium dioxide ceramic and preparation method thereof, comprises the following steps:
(1) utilize existing magnetic-controlled sputtering coating equipment, by metal titanium is splashed to ceramic surface, generate TiO at its surperficial natural oxidation
2film;
(2) under infrared light, baking is dry, then puts into stove and heat-treat, and namely obtains titanium dioxide ceramic after being cooled to room temperature.
Time of drying described in above-mentioned steps (2) is 6 ~ 8 hours.
Thermal treatment described in above-mentioned steps (2) is the temperature lower calcination 1 ~ 2 hour at 480 ~ 850 DEG C.
Adopt titanium dioxide ceramic prepared by aforesaid method.
The invention has the beneficial effects as follows: the advantage of this method is that sputter rate is high, process stabilizing, can prepare and have high performance TiO
2film; And the composition of film is easy to control, and is particularly suitable for suitability for industrialized production.
