Abstract
The invention discloses a method for preparing anti-bacterial ceramics by using epidesmine, which is characterized by comprising the following steps of: (1) preparing an epidesmine antibacterial agent by using natural epidesmine ores as raw materials, making the raw materials to 550 to 600-mesh powder by elutriation and pulverization, adding sodium zeolite, copper nitrate, zinc nitrate and silver nitrate in turn according to the proportion, stirring for 2 to 3 hours under the condition of heat insulation, placing the sodium zeolite, the copper nitrate, the zinc nitrate and the silver nitrate at the room temperature for 2 hours, and washing to be neutral and drying to obtain the epidesmine antibacterial agent with mixed load of copper, zinc and silver; and (2) adding the prepared epidesmine antibacterial agent into a material which is used for preparing ceramic glazes, and uniformly mixing to prepare the anti-bacterial ceramics. The anti-bacterial ceramics prepared by using the method has functions of antibacterium, mildew proofing, air purification, far infrared effect and the like, and can reach over 95 percent of antibacterium effect, can decompose organic matters and peculiar smells, and can prevent the surface from fouling and bacterial plaque; and the ceramics are more smooth and bright relative to the ceramics in the first step, and has the advantages of high efficiency and heat resistance.
Description
Technical field

2O.Natural parastilbite is that natural zeolite is the aluminium silicate mineral of a kind of aqueous basic metal or alkaline-earth metal, the tectosilicate of being made up of silicon-oxy tetrahedron and aluminum-oxygen tetrahedron.To have the monovalence end to obtain saturated for Sauerstoffatom in its aluminum-oxygen tetrahedron, and whole aluminum-oxygen tetrahedron has negative charge, comes compensation balance with near the positively charged ion of positively charged.Open structure helps ion-exchange, because the influence of hydrate free energy is bigger.Function with molecular sieve is as absorption and ion exchange.Have the following advantages as antibiotic carrier with stellerite: 1) successive cavity passage is arranged in the three-dimensional framework structure; 2) more uniform aperture is arranged; 3) big specific surface area is arranged; 4) bigger loading capacity is arranged; 5) good thermostability is arranged.
Make antiseptic-germicide with stellerite, particularly with the preparation of antimicrobial pottery of stellerite load copper, zinc, three kinds of antibacterial metal ions of silver, Shang Weijian has report.
Summary of the invention
The objective of the invention is to disclose a kind of method for preparing anti-bacteria ceramic with stellerite.
The present invention prepares the method for anti-bacteria ceramic with stellerite, comprises the steps:
1, is raw material with the natural parastilbite ore deposit, raw ore eluriated that grinding and processing is to the 550-600 order;
2, be that ratio is added in the na-pretreated zeolite successively with 1g na-pretreated zeolite, 0.1M cupric nitrate 5ml, 0.1M zinc nitrate 5ml, 0.1M Silver Nitrate 10ml, after under the insulation stirring reaction 2-3 hour, placed 2 hours under the room temperature, washing gets the antiseptic-germicide of copper, zinc, silver-colored mixed load to neutral after the oven dry;
3, the antiseptic-germicide with stellerite mixed load copper, zinc, silver-colored antibacterial metal ions adds in the glaze component;
4,, water glaze on ceramic base, the fired anti-bacteria ceramic that forms with the prior art for preparing glazing type material.
The mass ratio of the interpolation of described stellerite antiseptic-germicide is: glazing type material: stellerite antiseptic-germicide=100: 3;
The natural parastilbite that described stellerite produces for the Guangxi resource, its purity height, iron level is low to moderate 0.27, and whiteness is near 90%, and crystal is big.
The antibacterial experiment of stellerite anti-bacteria ceramic of the present invention shows, colibacillary antibiotic rate is reached 97%, and the antibiotic rate of streptococcus aureus is reached 93%.
Advantage of the present invention is: the anti-bacteria ceramic of preparation has antibiotic, mildew-resistant, purify air and function such as far infrared effect, and antibacterial effect reaches more than 95% and can decomposing organic matter and peculiar smell, prevents that dirt and bacterial plaque from appearring in the surface; With respect to general ceramic Paint Gloss becoming clear, the efficient height is heat-resisting.

Embodiment
Embodiment:
The chemical constitution and the processing condition of the antibiotic ceramic tile of preparation stellerite: 1, the stellerite ore that produces with the Guangxi resource is the antiseptic-germicide main raw material, and raw ore is eluriated, and grinding and processing is to the 550-600 order; 2, with the 1g na-pretreated zeolite, 0.1M cupric nitrate 5ml, 0.1M zinc nitrate 5ml, 0.1M Silver Nitrate 10ml are that ratio is added successively, after under the insulation stirring reaction 2-3 hour, place 2 hours under the room temperature, washing gets the antibacterial agent of copper zinc-silver mixed load to neutral after the oven dry.Antibacterial effect is outstanding and have high characteristics of Guangxi Zeolite whiteness high purity after the stellerite modification, can be directly adds in the Ceramic glaze material with 3% mass ratio to be fired into anti-bacteria ceramic.
Claims (4)
1. the method for preparing anti-bacteria ceramic with stellerite comprises that the making, overglaze of ceramic greenwave made, waters glaze, fired, and it is characterized in that:
