Description
Technical field
The present invention is a kind of durable inorganic anti-biotic material based on Catalysis Principles, relates to the fields such as textile industry of chemical industry such as coating, plastics and rubber and food service industry and fabric.It is characterized in that the synergy of anti-biotic material by quantized durable inorganic and hollandite type manganese dioxide molecular sieve based on Catalysis Principles, adopt the sterilization mechanism of catalytic activation oxygen, silver does not consume during sterilization, make anti-biotic material have high activity function to oxygen, cause antibacterial agent to have the broad-spectrum antiseptic ability of performance such as long-acting, efficient and stable, and human body is not had any adverse side effect.
The invention still further relates to above-mentioned anti-biotic material preparation method.
The invention still further relates to above-mentioned anti-biotic material and be applied to prepare antimicrobial products such as various coating, plastics, rubber and fabric.
Background technology
Nano anti-biotic material has vast market because of advantages such as antimicrobial efficiency height, good stability, nonpoisonous and tasteless and broad spectrum activities.Being usually used in nano anti-biotic material mainly is loaded Ag (Ag
2O), serial inorganic matter such as CuO or ZnO, because it is stronger that silver is antibacterial ability, Grain-positive, negative bacterium and mould and saccharomycete all there is effect preferably, and safety is good, human body is not produced toxic action, so present business-like antibacterial agent mainly is a silver is anti-biotic material, and be widely used in Related products such as coating, plastics, rubber and fabric.
Think that at present silver is that anti-biotic material mainly contains two kinds of mechanism: silver ion oozes out mechanism and catalytic activation oxygen mechanism.It is to be that anti-biotic material oozes out silver ion Ag by silver that silver ion oozes out mechanism
+With the microorganism combination, destroy cell synzyme, electric transmission system, respiratory system or material transfer system etc., cause microbial death.Present most inorganic antibacterial material all is to adopt silver ion to ooze out mechanism.As the TiAgZn compound system of CN 1568704A invention, the nano-TiO of CN 1742583A invention
2, ZnO and Ag
2The silver-colored aluminum sulfate system of O system and US20090047311 invention etc.Mechanism is because need constantly to consume Ag like this
+So the service life of antibacterial agent, (durability) was decided by the content of anti-biotic material silver, finally, exhausting of silver lost efficacy because of causing anti-microbial property.So ooze out the Ag of mechanism
+Antibacterial agent can not adapt to the economic strategy of sustainable development in service life and existing problems economically.
Catalytic activation oxygen mechanism mainly is that silver atoms (comprising band portion positive charge Ag ion) can become active oxygen species (as O airborne oxygen activation in air
-, O
2 -Perhaps O
2 2-Deng), or in liquid, activating solvent can be become living radical (HO or RO, R represents organic matter etc.), these active oxygen species or the nonselective destroy microorganisms matrix of living radical energy cause the death of microorganism.Such antibacterial agent does not have selectivity to microorganism, thus have the broad-spectrum sterilization performance, because,, have long-lasting and stable so bactericidal action does not consume noble metal silver based on the mechanism of catalysis.Therefore, the anti-biotic material of catalytic activation oxygen formula has silver ion and oozes out the advantage that the formula anti-biotic material can't be unrealistically compared.Has regular structure as carried metal silver on the CN 101187018A aluminium flake; CN 1857309A utilizes silver powder to make the spray that the women uses has good effect to various bacterium fungies etc.; US 20090130181 usefulness UV are with Ag
+In-situ reducing becomes metal A g on multiple natural with synthetic material, has efficient and long-acting anti-microbial property etc.
Nano particle has that size is little, surface area is big and surface atom occupies bigger characteristics such as ratio, so its surface can increase along with the minimizing of particle, variation is continuous or quantized like this.Monatomic as taking place when the size of material-1. → atom (group) bunch-2. → nanometer-3. → during the micron variation, significant variation can take place in the physical and chemical performance of material.This variation is a quantization or continuous, usually 1. 2. 3. the stage qualitative change can take place, studied Au/TiO as D.W.Goodman
2Material finds that 2-5 nanometer Au has better catalytic oxidation performance to carbon monoxide.Monatomic nano wire is the material category between monatomic, atom (group) bunch and nano material, its physical and chemical performance is along with great change will take place in the variation of length, so monatomic nano-material will have catalytic performance preferably, will cause the anti-microbial property of better catalytic activity oxygen formula.
The purpose of this invention is to provide a kind of durable inorganic anti-biotic material and preparation method and application based on Catalysis Principles with high-efficient and lasting anti-microbial property.
Summary of the invention
