Abstract
The invention relates to a preparation method of an antibiotic additive in the field of ceramic manufacture, in particular to a preparation method of a sliver-based nano ceramic glaze antibiotic additive. The invention also relates to the application of the additive. The preparation method is as follows: 5 portions of zinc chloride are dissolved into 20 portions of water, added with 0.1 to 1 portion of silver nitrate, and fully stirred; and then 0.5 to 1 portion of titanyl sulfate and 1 to 5 portions of saturated silver nitrate liquid are added; an oxalic acid solution is used for replacing the liquid into a metal oxalate complex; the metal oxalate complex is cleaned till the pH is equal to 5 to 6, and then baked for 6 hours in a kiln at the temperature between 420 DEG C and 600 DEG C. The additive prepared by the method can prevent the infection of other diseases like most social diseases, contagious skin diseases, and is widely applied in the aspects like ceramic sanitary ware and medical ceramic.
Description
Technical field
The present invention relates to preparation method's, particularly a kind of silver nano ceramic glaze water antibacterial additive the preparation method of the antimicrobial additive in a kind of ceramic manufacturing field, the invention still further relates to the using method of this additive.
Background technology
In the ceramic roasting process, adding the antimicrobial additive purpose in glaze water is to make sanitary ware have germicidal action, can ward off disease and propagate by sanitary equipment.Common pyroceramic nanometer additive can only be killed intestinal bacteria and streptococcus aureus, and it is relatively poor to press down the ability of killing Candida albicans; In addition, under traditional technology, the silver ions non-refractory in the additive, easily silver volatilization of calcining, behind the adding nanometer silver, glaze is fired easy blackout; Tradition nano-antibacterial technology needs the secondary glazing, the glaze intensity difference of firing indirectly, and time-consuming, energy consumption is high.
Summary of the invention
The technical problem to be solved in the present invention is for overcoming the shortcoming of prior art, providing a kind of and can effectively prevent the infection of contact disease, do not influence the silver nano ceramic glaze water antibacterial additive preparation method that glaze is fired quality.
In order to solve the problems of the technologies described above, the present invention realizes that as follows silver nano ceramic glaze water antibacterial additive preparation method of the present invention is as follows:
(1) 5 parts of zinc chloride is dissolved in 20 parts of water, adds 0.1～1 part of Silver Nitrate then, stir.
(2) add 0.5～1 part of titanyl sulfate and an amount of silver nitrate solution.
(3) with oxalic acid solution above-mentioned solution displacement is formed the oxalic acid metal salt complex.
(4) above-mentioned oxalic acid metal salt complex is washed to PH=5～6.
(5) in kiln with 420 ℃～600 ℃, roasting 6 hours.
The using method of silver nano ceramic glaze water antibacterial additive of the present invention is as follows:
(1) add the silver nano ceramic glaze water antibacterial additive for preparing by the method for the invention in glaze water, additive accounts for 2%～3% of glaze water gross weight.
(2) glaze is fired through 1000 ℃～1400 ℃.
Positively effect of the present invention is as follows: adopt the antimicrobial additive of method manufacturing of the present invention to generate the alloy of sodium rice silver with zinc oxide and other precious metal when high temperature, after having added the glaze water calcining of this antimicrobial additive, still have the nanometer silver of some amount to exist, change silver ions non-refractory under traditional technology is calcined easy silver-colored evaporable phenomenon; Common pyroceramic nanometer additive can only be killed intestinal bacteria and streptococcus aureus, it is relatively poor to press down the ability of killing Candida albicans, the present invention has obvious effects to suppressing Candida albicans, can effectively prevent the infection of venereal disease, tetter and other contact diseases; This additive adds in the various glaze water through after the differing temps roasting, and the glaze color and luster is still pure white mellow and full, the phenomenon that the nanometer silver glaze is fired blackout can not occur adding; This antiseptic-germicide can with the direct blend of glaze water, carry out a glazing, directly calcining, the intensity height, simple to operate, having changed other nano-antibacterial technology needs the secondary glazing, fires intensity difference indirectly and causes the problem of time-consuming power consumption; The Ceramic glaze that adds this antiseptic-germicide has the long acting antibiotic performance.
Embodiment
Now the present invention is described in further detail with specific examples.
The preparation method of silver nano ceramic glaze water antibacterial additive:
(1) 5 gram zinc chloride is dissolved in the 20 gram water, adds 0.1～1 gram Silver Nitrate then, stir.
(2) adding 0.5～1 in above-mentioned solution restrains titanyl sulfate and adds the saturated silver nitrate solution of 1～5 gram.
(3) with oxalic acid solution above-mentioned solution displacement is formed the oxalic acid metal salt complex.
(4) above-mentioned oxalic acid metal salt complex is washed to PH=5～6.
(5) in kiln with 420 ℃～600 ℃, roasting 6 hours.
The using method of silver nano ceramic glaze water antibacterial additive
(1) silver nano ceramic glaze water antibacterial additive 2～3 that adds by the method for the invention preparation in 100 gram glaze water restrains.
(2) glaze is fired through 1300 ℃.
It is main raw material(s) that silver nano ceramic glaze water antibacterial additive is selected with nanometer silver and nano zine oxide, add raw materials such as nano-titanium oxide, precious metal palladium, nanometer silver is grafted to the surface of nano zine oxide by a series of chemical processes, wrap up nanometer silver with nano zine oxide, the performance of the two all can further be embodied.Under high-temperature situation, part silver has formed the multiple metal alloy body based on silver-colored zinc, has improved silver ions reservation quantity at high temperature.Add the 2-3% antiseptic-germicide by overall proportion during preparation antibacterial glaze water, after glaze is fired through 1300 ℃, the glaze that burns till is carried out surface property check and physical mechanics check, antimicrobial additive is little to glaze surface physics structure and physical and mechanical property influence; The surface chemistry Performance Detection finds obviously to contain silver ions; By the anti-microbial property test, this product is to intestinal bacteria, and the streptococcus aureus antibiotic rate can reach 99% all more than 99.9% to the Candida albicans antibiotic rate, and same sample repetition test antimicrobial efficiency can not reduce.Adopt the additive of the method for the invention preparation, can prevent the infection of other diseases such as most of venereal diseases, contact tetter after the application, at china sanitary ware and medically have purposes widely aspect ceramic.
