Description
Technical field
It is especially a kind of the present invention relates to a kind of synthetic method of layered hydroxide antimicrobial powder and products thereof and application
Synthetic method of copper zinc compound antibacterial powder and products thereof and application.
Background technology
Layered hydroxide is one kind by positively charged layers of metal hydroxides and the exchangeable anions in interlayer
The two-dimensional solid of composition.The layered hydroxide that people have found first is U.S. aluminum hydrotalcite, its Stability Analysis of Structures, element can design,
Memory effect, interbed adsorption effect have all attracted many people to be studied.The element that natural hydrotalcite has is to be extremely limited
, therefore have devised many new hydrotalcite materials using the interchangeable characteristic of its cation, people.
Currently used antiseptic is divided into inorganic antiseptic, organic antibacterial agent and natural antibacterial agent.Inorganic antiseptic is usual
Refer to the inorganic matters such as silver, copper, zinc, mainly kill mushroom, wherein silver system substance germicide energy using its oxidation activity and dissociated ion
Power is most strong, but exist silver ion have micro- toxicity and activity it is too strong, easy to change the problems such as, and copper system material to fungi lethality compared with
By force, bacterium is not almost acted on then, zinc system then anti-microbial property only on；The principal item of organic antibacterial agent have vanillic aldehyde and
Ethyl vanillin aldehydes compound, but organic antibacterial agent is present that security is unknown, heat resistance is poor, the problems such as easily hydrolyzing；Naturally
Antiseptic mostlys come from the extraction of the natural plants such as mustard, chitin, horseradish, but has that bactericidal effect is limited, stability is poor
The problems such as.
