Abstract
The invention discloses a preparation method for an antibacterial agent containing copper, silver and zinc antibacterial metal ions. The method comprises the following steps of: (1), levigating, crushing and processing epidesmine to 550 to 600 meshes; (2), acidulating each gram of epidesmine with 40ml of 0.1M hydrochloric acid, reacting the epidesmine and 20 percent of sodium chloride at a constant temperature for 2 hours with maintaining and stirring, standing the reaction product, washing the reaction product until the reaction product is neutral, and drying the reaction product; and (3), sequentially adding 1g of sodic zeolite, 5ml of 0.1M copper nitrate, 5ml of 0.1M zinc nitrate and 10ml of 0.1M silver nitrate into modified sodic zeolite, performing a reaction at a constant temperature for 2 to 3 hours with maintaining and stirring, standing the reaction product, washing the reaction product until the reaction product is neutral, and drying the reaction product to obtain the antibacterial agent. The epidesmine antibacterial agent has the advantages of strong antibiosis, high efficiency, heat resistance, good stability, high safety, good long-term effectiveness, wide antibacterial range and the like. Bacteria have no medicament resistance to the epidesmine antibacterial agent; the antibacterial effect is over 95 percent; and the cost is low.
Description
Technical field
The present invention relates to antibacterial agent, specifically is a kind of antibacterial agent that contains copper, silver and zinc antibacterial metal ions and preparation method thereof.

2O.Natural parastilbite is that natural zeolite is a kind of moisture alkali metal or the aluminium silicate mineral of 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 oxygen atom in its aluminum-oxygen tetrahedron, and whole aluminum-oxygen tetrahedron has negative electrical charge, comes compensation balance with near the cation of positively charged.Open structure helps ion exchange, because the influence of hydrate free energy is bigger.Function with molecular sieve is like absorption and ion exchange.Have the following advantages as antibiotic carrier with epidesmine: 1) continuous empty passage is arranged in the three-dimensional framework structure; 2) more uniform aperture is arranged; 3) big specific surface area is arranged; 4) bigger ion exchange capacity is arranged; 5) good heat endurance is arranged.
With epidesmine as antibacterial agent; (the 21st the 03rd phase of volume of " mineral journal " calendar year 2001) is loaded with Shen Shaohua, Zhang Shugen, David Wong comrade's article (metal ion type inorganic antiseptic); Having introduced epidesmine in the article produces the technology of silver antibacterial agent and is: under the normal temperature; With the AgNO3 solution of 0.2mol/l and 2 times of amounts, granularity mixes less than 200 purpose epidesmines, stir 24h after, filter wash, oven dry; The technology of production of copper antibacterial agent and zinc antibacterial agent is: under 100 ℃, with the sulfate liquor of this metal of 0.4mol/l and 2 times of amounts, granularity is less than 200 orders, mix through the pretreated epidesmine of ammoniacal liquor, stir 2h after, filter wash, oven dry.Do not see as yet that at present having with the Guangxi epidesmine is the report of the antibacterial agent of three kinds of copper, silver, zinc metal ion mixed load that anti-microbial property is arranged.
Summary of the invention
The objective of the invention is to provide a kind of antibacterial agent that contains copper, silver and zinc antibacterial metal ions and preparation method thereof.
A kind of antibacterial agent that contains copper, silver and zinc antibacterial metal ions of the present invention, its preparation method comprises the steps:
1, the stellerite ore that produces with the Guangxi resource is a primary raw material, and raw ore is eluriated, and grinding and processing is to the 550-600 order;
2, sodium type modification: 40ml is that ratio is carried out acidifying with 1g epidesmine 0.1M hydrochloric acid, with the sodium chloride of the epidesmine after the acidifying and 20% at insulation stirring reaction 2 hours down, room temperature held 2 hours, washing gets na-pretreated zeolite to neutral after the drying;
3, antibacterial modified: with the 1g na-pretreated zeolite; 0.1M being ratio, copper nitrate 5ml, 0.1M zinc nitrate 5ml, 0.1M silver nitrate 10ml add to successively in the modification na-pretreated zeolite; After under the insulation stirring reaction 2-3 hour; Room temperature held 2 hours, washing get the epidesmine antibacterial agent of copper zinc-silver mixed load to neutral after the oven dry.
The antibacterial antiplaque agent determination of activity that the present invention makes shows: the mixed load zeolite antibacterial agent reaches 7.1 * 10 respectively to colibacillary MIC minimal inhibitory concentration and the minimum antibiotic concentration of MBC
-8G/mL and 1.6 * 10
-7G/mL.
Advantage of the present invention is:
(1) it is strong that the epidesmine antibacterial agent that makes has an antimicrbial power, and efficient is high, and is heat-resisting, good stability; Safe, long-lasting good, advantage such as antibacterial range is wide; And bacterium has no drug resistance to the epidesmine antibacterial agent, and antibacterial effect reaches more than 95%, and cost is starkly lower than general antibacterial agent;
(2) good stability can directly mix in various raw materials such as resin, can easily process multiple anti-bacterial material, need not change the existing technological process of production, has greatly range of application;
(3) epidesmine has outstanding specific surface area, prepares antibacterial agent with epidesmine, and antibiotic ion is efficiently distributed, and can under the prerequisite that reaches industry each item index, effectively reduce cost;
(4) epidesmine purity in Guangxi is high, and iron content is low to moderate 0.27, and whiteness is near 90, and crystal is big, and the anti-bacteria ceramic quality of production is higher.
