Abstract
The invention discloses a method for preparing an antibiosis sponge using an epidesmine, which uses a natural epidesmine as the raw material, and includes the following methods: elutriating, crushing and processing the epidesmine into 550-600 meshes; according to sodium type zeolite, adding cupric nitrate, zinc nitrate and silver nitrate proportionally in order, stirring and reacting for 2-3 hours with insulation, placing the product at the room temperature for 2 hours, washing the product to neutral, and drying the product and obtaining an epidesmine antiseptic; adding the prepared epidesmine antiseptic into a sponge base material, uniformly mixing the prepared epidesmine antiseptic with the sponge base material, and foaming the product for preparing the epidesmine antiseptic sponge. The antibiosis sponge prepared by the method has the functions of antibiosis, mildew-resistance, air purification, decomposition of organic matter and peculiar smell, kill of bacteria and mould on the surface of contacted product, and more than 95% bacterium can be resisted. The epidesmine antiseptic has good dispersion performance, and is easy to be uniformly dispersed in the foaming material with good safety and without influence on the foamability, and after long time usage or multi-time washing, the product can keep good antibacterial property.
Description

2O.Natural parastilbite is that natural zeolite is the aluminium silicate mineral of a kind of aqueous basic metal or earth alkali 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 IX, because the influence of hydrate free energy is bigger.Function with molecular sieve is like absorption and ion exchange.
With the preparation of antimicrobial sponge of stellerite copper loaded, 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 antibacterial sponge with stellerite.
The present invention prepares the method for antibacterial sponge 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; Room temperature held 2 hours; Washing gets the antiseptic-germicide of copper, zinc, silver-colored mixed load to neutral after the oven dry;
(3) antiseptic-germicide with stellerite mixed load copper, zinc, silver-colored antibacterial metal ions adds in the sponge substrate;
(4) with prior art with the sponge substrate processing of foaming, make antibacterial sponge.
The mass ratio of the interpolation of described stellerite antiseptic-germicide is: sponge Ji Cai ︰ stellerite antiseptic-germicide=100 ︰ 3.
The natural parastilbite that described stellerite produces for the Guangxi resource, its purity is high, and iron level is low to moderate 0.27, and whiteness is near 90%, and crystal is big.
The antibacterial experiment of stellerite antibacterial sponge of the present invention shows, colibacillary antibiotic rate is reached 98%, and the antibiotic rate of streptococcus aureus is reached 94%.
Advantage of the present invention is: functions such as the antibacterial sponge of preparation has antibiotic, mildew-resistant, purify air, antibacterial effect reach more than 95% and can decomposing organic matter and peculiar smell, can kill bacterium, the mould on contact product surface; Stellerite antiseptic-germicide dispersing property is good, is easy to homodisperse in foam material, and is safe, and foam performance is not almost had influence, and warp uses for a long time or repeatedly washs and still keeps the excellent antibiotic performance.
Embodiment
The chemical constitution and the processing condition of preparation stellerite antibacterial sponge: the stellerite ore that 1, 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, room temperature held 2 hours, washing is to neutral; After the oven dry the antibacterial agent of copper zinc-silver mixed load, can be directly add to foam in the sponge substrate and process antibacterial sponge with 3% mass ratio.
The technical process of preparation is: stellerite elutriation → dry ground → antibacterial modified → insulation, stirring → washing → drying → be mixed into antibacterial sponge base material → foaming → slaking → cutting → finished product.
Claims (4)
1. one kind prepares the method for antibacterial sponge with stellerite, it is characterized in that: comprise the steps:
(1) with the stellerite ore be raw material, warp elutriation, grinding and processing are to the 550-600 order;
(2) again 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 in the na-pretreated zeolite successively; After under the insulation stirring reaction 2-3 hour; Room temperature held 2 hours, washing get the stellerite antiseptic-germicide of copper, zinc, silver-colored mixed load to neutral after the oven dry;
(3) the above-mentioned stellerite antiseptic-germicide that makes is added in the sponge substrate, mix, and then process the stellerite antibacterial sponge.
2. method according to claim 1 is characterized in that: the interpolation mass ratio of stellerite antiseptic-germicide is: sponge Ji Cai ︰ stellerite antiseptic-germicide=100 ︰ 3.
3. method according to claim 1 is characterized in that: the natural parastilbite that said stellerite ore produces for the Guangxi resource.
