Description
Technical field
The present invention relates to air purifying preparation field, and air purifying preparation and its preparation side are sustained more particularly, to a kind of controllable type
Method.
Background technology
Pollutant in room air includes benzene, ammonia, aromatic hydrocarbon, formaldehyde, hydrogen sulfide etc., and also there is various causes in air
Sick type microorganism.Common air freshener is typically with fragrance covering smell, it is impossible to purifies the bacterium in air or killing air.
Chlorine dioxide is a kind of good bactericide and eliminating smell agent.Can be discharged when it is contacted with microorganism nascent oxygen and
Hypochlorous acid molecule, there are preferable adsorptivity and penetrability to microbial cell, effectively can include the enzyme of sulfenyl by oxidative cell, make
Amino-acid oxidase in protein decomposes, quick to control microprotein synthesis, so as to kill bacterium or bacteria growing inhibiting.
It has good killing action to gemma, virus, algae, fungi, iron blood bacterium, sulfate reducing bacteria etc., and to higher mammal
Eucaryotic cell structure is then entirely without influence.World Health Organization WHO confirms that chlorine dioxide is wide spectrum, efficient, quick, lasting, nontoxic nothing
Harmful A1 level security disinfectants, it is the universally acknowledged forth generation green product for substituting chlorine system disinfectant.Chlorine dioxide
Chemical property is active, typically imports purified chlorine dioxide in the inertia solution being made up of stabilizer, is made colourless
Or faint yellow clarification, colourless odorless stability chlorine dioxide water solution, its property is stable, not volatile or decomposition, during use
Add activator activation.But effective acquisition time is shorter after liquid chlorine dioxide activation, and transports, store and using not square
Just.The developed country such as Japan develops solid chlorine dioxide production technology in recent years, using any special measures by stability titanium dioxide
Solutions of chlorine is solidificated on carrier.Compared with liquid chlorine dioxide, this solid articles can be widely applied to relative closure space such as

There is the features such as portable, easy-to-use, safe.
But above-mentioned chlorine dioxide slow-release gel products have the shortcomings that common：1st, stable ClO 2 solution is prepared
First have to prepare chlorine dioxide of the purity more than 90%, it is then complicated with alkali liquor absorption, preparation technology；2nd, product
Acquisition time is shorter, and less than 2 months or so, rate of release was indefinite, unstable, it is difficult to adapt to market difference air pollution concentration field
Purified demand.
In view of drawbacks described above, creator of the present invention obtains the present invention finally by prolonged research and practice.
The content of the invention
To solve above-mentioned technological deficiency, the technical solution adopted by the present invention is, there is provided a kind of controllable type sustained release air is net
The preparation method of agent, comprises the following steps：10-25 parts stabilizer, 0.1-2 part chelating agent deionized waters are taken according to parts by weight
Fully dissolving, 6-20 part sustained release agents are added, the stirring and dissolving at 50-60 DEG C, 8-24 part titanium dioxides are added after being cooled to room temperature
Chlorine precursor, is sufficiently stirred, and then adds 1-10 part colloidal powders, being slowly stirred, which makes it be poured into after being uniformly dispersed in mould, is cooled into
Gel with holes；During using the gel purification air with holes, 40-60 parts activator is imported into the hole of the gel with holes to send out
Raw reaction release chlorine dioxide, and the dosage of the regulation chlorine dioxide precursor and the species concentrations of the activator can make dioxy
The rate of release for changing chlorine body is controllable.
Preferably, the chlorine dioxide precursor is one kind in sodium chlorite, potassium chlorite, magnesium chlorite, barium chlorite
It is or several.
Preferably, the activator is phosphate buffer, citrate buffer solution or borate buffer solution.
Preferably, the chelating agent is in ethylenediamine tetra-acetic acid, disodium ethylene diamine tetraacetate, tetrasodium ethylenediamine tetraacetate

Fig. 1 is inventive gel network structure schematic diagram.
Embodiment
The forgoing and additional technical features and advantages are described in more detail below.
Embodiment 1
The method for preparing the sustained-release chlorine dioxide gel of the present embodiment, comprise the following steps according to parts by weight take 10 parts it is anhydrous
Calcium chloride as stabilizer, 2 parts of disodium ethylene diamine tetraacetates as chelating agent, with the agent of deionized water steady dissolution and chelating agent,
6 parts of polyacrylamides are added as sustained release agent, the stirring and dissolving under temperature 50-60 degree, 24 part two are added after being cooled to room temperature
Chlorine monoxid precursor is sufficiently stirred, and sodium chlorite is used in the present embodiment as chlorine dioxide precursor, then adds 10 parts of colloidal powders,
Polyacrylate is used in the present embodiment, being slowly stirred makes it be uniformly dispersed, and pours into the mould of solid shape and cools down, and forms band
Hole or with gap gelatinous solid.40 parts of activators are imported into the hole or gap of the gelatinous solid during use, this reality
Apply and use phosphate buffer to be penetrated into as activator, the activator in gel rubber system in example, dissociate caused by activator
Hydrogen ion reacts with the chlorine dioxide precursor, discharges chlorine dioxide.Reactional equation is as follows：
5ClO2 -+4H+=4ClO2↑+Cl-+2H2O
As shown in figure 1, chlorine dioxide precursor makes it coexist in gel with sustained release agent, stabilizer due to the agent parcel that is chelated
In system, chlorine dioxide precursor and the H that dissociates in system are greatly reduced+Interaction speed, and generate ClO2Gas 1
In network structure in gel 2, cause ClO2The speed that gas 1 is diffused into from gel 2 in air reduces, therefore chlorine dioxide
It can be discharged in generation, so as to be truly realized the slow release of chlorine dioxide.The chlorine dioxide for having strong oxidizing property is slowly released
Put, the poisonous and harmful strong reducing property gas formaldehyde slowly discharged can be directed to, purified.Therefore the present invention is suitable for removing finishing
Put that family product, automotive trim etc. be long-term afterwards or newly and the formaldehyde that slowly discharges, and can disinfection, realize room air
Thorough purification.The sustained-release chlorine dioxide gel of the present invention, can be according to different needs by adjusting chloritic dosage and work
The species concentrations of agent prepare the chlorine dioxide gel of different rate of release.If the room not yet moved in after new finishing,
The chlorine dioxide gel of high concentration quick release can be used, if it is new put furniture or car after remove formaldehyde, someone feelings
Under condition, the chlorine dioxide gel that can be discharged at a slow speed with low concentration.
The sustained-release chlorine dioxide gel of the present invention can be discharged 3~6 months with certain velocity-stabilization, and acquisition time is long, releases
Put that speed is uniform and stable, effect is lasting；It can not only efficiently, safely, enduringly remove the formaldehyde in room air, formaldehyde removing
Rate is high, additionally it is possible to carries out continuous disinfection sterilization to room air, thoroughly purifies the air of a room；And without using high-pure chlorinedioxide
Gas, preparation method is simple, easy to operate.
The present invention also can be used for toilet, kitchen, living room, refrigerator, shoe chest etc., remove nitrogenous, sulphur, the compound of oxygen
With the peculiar smell in the smelly source such as halogen derivatives.And gel stores, be easy to carry, safe and non-toxic, cost is cheap.
