Preferred version of the present invention is described with reference to the accompanying drawings.
Fig. 1 represents to prepare the illustrative methods of inorganic ceramic composite composition of the present invention.
1. the preparation and the process of silver coating nano particle
(1) preparation silver nano-grain
In order to obtain maximum antibacterial effect with a spot of composition, can add silver nano-grain, can prepare described nano particle in the following manner.
With non-ionic surfactant polyoxyethylene mono-laurate and AgNO
3Mix and prepare mixing solutions, wherein can use the tensio-active agent of any kind of, for example cats product, anion surfactant or neutral surface active agent, but consider neutral surface active agent's structure, preferred use for example has the Vinlub 73 (polysorbate20 (polysorbate 20)) of functional group.In order to prepare silver-colored particulate, the aqueous solution that is dissolved with sodium borohydride is joined in this mixing solutions as reductive agent, therefore, when institute's dissolved silver ion reduction, the color of mixing solutions at last will be by the colourless Vandyke brown that becomes, and the result prepares silver-colored particulate.Therefore on the other hand, the tensio-active agent of adding will prevent silver-colored particle growth, can obtain the colloidal solution of silver-colored microparticulate in the aqueous solution.After preparing silver-colored particulate by this way, in order to remove responseless residue and impurity, centrifugal described mixing solutions under the speed of 5000～8000rpm, through centrifugal, described mixing solutions is divided into two-layer, and one deck is a silver nano-particle, and another layer is a supernatant liquor.Remove supernatant liquor then, the particulate that washing obtains three times is so that obtain at last by the stable silver colloid of tensio-active agent.
(2) process of silver coating nanoparticle
For homodisperse, can be coated with the silver nano-particle that obtains by aforesaid way.In this coating process, add 0.5%HCl or HF solution and come 4000 order tourmaline powders are carried out acid treatment, on the surface of tourmaline powder, produce a large amount of SiOH groups then, remove impurity simultaneously, therefore can easily be stained with silver nano-particle.For the silver-tourmalinite complex body that obtains being coated with silver nano-particle, can in silver colloid, add appropriate amount with resulting tourmaline powder after the acid treatment, stir, then with this complex body 110 ℃ dry 6 hours down.In order to obtain the antibacterial effect more than 99.9%, in coating process, the final content of silver is preferably greater than 0.02 weight %.Therefore, the glue spread of silver nano-particle is preferably 0.1～0.4 weight % of tourmalinite weight.
2. prepare and be coated with the process of gold nano grain
In order to stimulate circulation, can add and the very a spot of gold of coating with the form of nano particle.With currently known methods for example the polyvalent alcohol legal system be equipped with gold nano grain.Prepare HAuCl at first, in the following manner
4Solution: will join as the Polyvinylpyrolidone (PVP) (PVP, molecular weight 40,000) of reductive agent and particle size adjustment agent in the ethanolic soln with preparation ethanol-PVP solution, and add a spot of dispersion agent to this ethanol-PVP solution then, and then add HAuCl
4Thereby make HAuCl
4Solution.
This HAuCl refluxes under the alcoholic acid boiling temperature
4Solution 4 hours is with reduction Au ion, owing to the formation of gold nano particulate makes solution colour become red-violet colour from gold.For the gold nano particulate that disperses effectively to obtain, gold colloid can be joined in the illite powder, then this gold colloid was stirred 1 hour at least, so that gold nano particulate easily is adsorbed onto on the surface of illite powder by the strong surfactivity of gold nano particulate.Then obtain gold-illite complex body, wherein, gold nano particulate is coated in the active sites or hole of illite powder.Dry this complex body under 80 ℃ of temperature is so that obtain being coated with the illite powder of gold nano particulate.The size at bronze end usually can be greater than several microns, and the size of gold nano particulate is about 5nm, therefore very a spot of gold just can be being dispersed on the whole illite powder, and the gold that is coated on the same amount on the illite powder of the present invention just is enough to improve blood circulation.
3. dispersion process
Preparation has the mixture of following component and content thereof: the tourmaline powder of the silver nano-grain that is coated with 0.1～0.4 weight % that accounts for above-mentioned tourmalinite weight of 20～40 weight %; The illite powder of the gold nano grain that is coated with 0.01～0.05 weight % that accounts for illite weight of 30～10 weight %; Zeolite powder with 40～20 weight %.
Usually, if a spot of a kind of compound is mixed mutually with a large amount of another kind of compound, then concentration is uneven in whole mixture, but according to the difference of position and difference.In order to address the above problem, add the fusing point conditioning agent in the group of forming by saltpetre, SODA ASH LIGHT 99.2 and borax of being selected from of 10～20 weight % to this mixture, thereby intergranular distance is reduced, and the temperature of reduction melt forming process.In order to form homogeneous mixture, the following component that can add following content: 5～20 weight % are selected from mineral substance in the group of being made up of jade, germanium, rare-earth elements of lanthanum and barium, or the basic oxide of 5～20 weight %, these basic oxide contain have a high potential gradient and be selected from least a element in the group of forming by Li, Na, K and Ca and the silver powder of 0.5～5 weight % with superior electrical conductivity; 0.5 the Fe of the generation geomagnetic effect of～5.5 weight %
2O
3Nano particle, wherein, the weight percent of each compound is all based on the gross weight of tourmalinite, illite, zeolite and conditioning agent.In this specification sheets and appended claim, if not otherwise specified, weight percent is represented the amount with respect to the gross weight of main components such as tourmalinite, illite, zeolite and conditioning agent.The mixture that adds described adjusting fusing point to described nanometer powder mixture, use ball mill or masher under 150～250rpm, to distinguish dispersion treatment 6～12 hours or 0.5～2 hour, thereby obtain the composition that is mixed with complex body of every kind of component homogeneous phase distribution on the whole.
4. heat treatment process
In order to improve far infrared rays and anionic emission, can in the melt forming process, handle the multifunctional ceramic powder that obtains by aforesaid method.Calcination process makes the grain pattern reorganization in the described ceramic powder, thereby has improved far infrared and anionic emission measure.In calcination process,, then be difficult to form the powder phase because of the excessive fusion of contained mineral substance if treatment temp is being higher than 900 ℃.In this case, the electroconductibility of tourmalinite reduces greatly, and the crystalline structure of zeolite caves in fully, thereby produces the amorphous compound that does not have pore.Therefore the temperature of calcination process must be than far below 900 ℃.For mineral substance characteristic that is maintained original and the ceramic powder that therefore has the deodorization of excellent far infrared rays and negatively charged ion emitting performance and excellence, calcination process can carry out under 450～750 ℃ temperature 8～24 hours, preferably carried out under 500～700 ℃ 12～16 hours.Depend on the calcination process temperature the multifunctional ceramic powder structural changes as shown in Figure 2.
With the multifunctional ceramic powder of method for preparing can be used to form the pearl of straw mats, as the coating of clothes, footwear or strainer, and can join in the household articles for use.In these purposes, if the mean diameter of powder greater than 600 orders, then the surface of product will be coarse, or can form the cavity in product, therefore by the classification process behind the calcination process, the mean diameter that preferably makes powder is 325～600 orders.
