Description
Technical field
The present invention is the preparation method of a kind of slow released ClO 2 powder, is specifically related to formaldehyde in indoor air etc. and is harmful to
The purified treatment of material, belongs to air purification field.
Background technology
Formaldehyde has another name called formaldehyde, is a kind of colourless gas with penetrating odor, and density is slightly above air, soluble in water,
It is the organic compound of a kind of highly volatile, is mainly used in all kinds of ornament materials, such as wall covering fabric, patch wall chemical fibre, carpet, foam
Plastics, paint and coating etc., therefore, be also one of the maximum indoor pollutant that is detrimental to health.In modern house environment,
The concentration over-standard of formaldehyde can cause Nausea and vomiting, cough, uncomfortable in chest, the even symptom such as emphysema of panting, along with economic high speed is sent out
Exhibition and the improving constantly of Living consumption, people are to living environment, the comfort level of working environment, cosmetic requirements increasingly
Height, meanwhile, also brings the pollution problem of a series of improvement formaldehyde in indoor air.The side of existing improvement formaldehyde in indoor air
Method mainly has physical method, chemical method and biological method, and wherein, physical method is to use the physical measure such as ventilation, absorption,
Will not produce secondary pollution, whole process is mild, the longest；Then use can be with formaldehyde generation chemical reaction more for chemical method
Material, react with formaldehyde under certain condition and produce the less novel substance of another kind of toxicity or absorb formaldehyde, whole process is acute
Strong, the shortest, but certain secondary thing pollutant can be produced；Biological method mainly uses plant to the first purifying in indoor environment
Aldehyde pollutes, and by photosynthesis and the adsorption of plant, decomposes formaldehyde a small amount of in air, and whole process will not produce secondary
Pollutant, but owing to plant is Passive intake formaldehyde, therefore, the effect to controlling concentration of formaldehyde is less.
In recent years, constantly burning hot along with indoor decoration, eliminate the formaldehyde that upholstery material comes out, it has also become people
Question of common concern, and chlorine dioxide is as a kind of new and effective disinfection sanitizer, not only eliminates in air at many
The report of Pollutant Formaldehyde carried out record, in patent documentation CN1887356 (a kind of slow released ClO 2 air sterillization
Agent, 2007.01.03), CN2841013 (the air disinfection and refreshing box of slowly-releasing chlorine dioxide gas, 2006.11.29) also has
Disclose, mainly utilize the oxidisability of chlorine dioxide, oxidize the formaldehyde into formic acid until carbon dioxide and be removed, when in reality
During use, owing to the boiling point of chlorine dioxide is only 11 DEG C, boiling point is relatively low, and when producing, the chlorine dioxide of gaseous state exists again vivaciously
And the characteristic such as instability, generally require and carry out extemporaneous preparation, cause concentration wayward, therefore, using effect is unsatisfactory, if
, then there is the defects such as complex manufacturing process, meet the tendency for this present invention in the silica gel product using patent documentation CN1887356 to disclose
And give birth to.
Summary of the invention
It is an object of the invention to provide the preparation method of a kind of slow released ClO 2 powder, a kind of powdery of main offer
The powder product of form, operating process is very simple, the component in formula standby, the most on request after being individually dried
Proportioning carries out hybrid reaction, and in actual use, its chlorine dioxide discharged can not only be the most right
Formaldehyde in room air aoxidizes, the generation of oxidizing process non-secondary pollution thing, also has easily preservation, long shelf-life etc. excellent
Gesture, is particularly well-suited to industrialized large-scale production, and cost of manufacture is cheap.
The present invention is achieved through the following technical solutions: the preparation method of a kind of slow released ClO 2 powder, overcomes existing
There is the manufacturing process using silica gel to make slow released ClO 2 air disinfectant as colloidal powder in technology and to exist numerous and diverse
Defect, it is provided that the product form of a kind of powdery, comprises the steps:
A: get the raw materials ready, prepares, by weight percentage respectively to the formula constituent of described slow released ClO 2 powder
Meter, the formula of described slow released ClO 2 powder includes:

Further, described activator is when dry, every stirring in 20～30 minutes once.
In described step C, described formula constituent stirs by mixing, and the composition being finally mixed into during mixing
For activator, it is generally the case that the powder humidity applicable industry dehumidifier being mixed into controls moisture content below 40%.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) product that the present invention makes is powder product, can be placed directly in indoor environment, the chlorine dioxide of its release
Gas can aoxidize for the formaldehyde in room air, formic acid can be oxidized the formaldehyde into until carbon dioxide and be removed,
The generation of oxidizing process non-secondary pollution thing, practical effect is good.
(2) production method of the present invention is simple, is particularly suited for industrialized large-scale production, has operating process letter
The advantages such as list, cost of manufacture are cheap.
(3) the recipe ingredient preparation that the present invention relates to is reasonable, the composition of gel, slow releasing agent and filler, the most effectively
Improve the stability during product packing and storing, it is to avoid react between each component, reach to extend shelf life of products
Purpose, practicality is extremely strong.
(4) after the present invention uses, owing to being added with gel, therefore, after reacting with moisture in air, can be by powder shape
State changes into colloid form, owing to gel selects AQUAGEL PLUS gel, moreover it is possible to effective control in colloid form two
The rate of release of chlorine monoxid, has the advantages such as easy preservation, long shelf-life.
