Description
Technical field
The present invention relates to a kind of air purifying preparation, relate in particular to and adopt formaldehyde remover and preparation method, belong to the environment-friendly products technical field.
Background technology
Along with rapid economy development, living standards of the people improve day by day, and the finishing in office and family place is more and more general, bring hidden danger but fit up improper people's the health of also can giving.In recent years, the healthy incident of air pollution harm resident that causes because of interior decoration happens occasionally, especially the formaldehyde that is contained in the finishing material, a kind of strong carcinogen that has been identified, mainly the respiratory tract to human body exerts an influence, be an allergen, cause cough, uncomfortable in chest, asthma, various anaphylaxis, ophthalmic and nasopharyngeal carcinoma etc.At present, formaldehyde remover has tens kinds on the market, and major part is a liquid preparation, is sprayed onto during use in the space, can waste a lot of effective ingredient like this, and be intermittently operated, continues the effect of release, and some also can produce secondary pollution.Also some absorbent-type formaldehyde remover must have the forced circulation of air just can reach effect preferably, otherwise acts on limitedly, can not fundamentally remove formaldehyde.
Chlorine dioxide is a kind of internationally recognized efficient, nontoxic, quick, broad-spectrum disinfection sanitizer, it has 100% sterilization effect to antibacterial, fungus, virus, spore, also can to harmful substances such as the formaldehyde in the room air, toluene very ideal Degradation be arranged by its powerful Oxidation.Chlorine dioxide has good deodorizing effect, the atomic oxygen that it produces can become nitrogen with the ammonia dehydration, odorous gas such as hydrogen sulfide, sulfur dioxide and mercaptan are oxidized to sulphuric acid or sulfonic acid and remove, thereby become a kind of air pollution cleanser of new generation of superior performance.But the chlorine dioxide instability, difficult the storage needs in situ preparation, thereby needs a kind of preparation means.The preparation method that Chinese patent discloses a kind of formaldehyde remover No. 200610134083.9, it is used to dispel formaldehyde with chlorine dioxide, but the preparation of product and methods for using them that this invention provides is all very complicated, and the The field dosage form is liquid, be difficult for moving, effective life, is short.No. 200710139426.5 disclosed a kind of fragrant type sustained-release chlorine dioxide gel rubber powders of Chinese patent and preparation method, also chlorine dioxide is used for air sterillization, the patented product chlorine dioxide discharges mild, effective life, is longer, can dispel formaldehyde and air is carried out disinfection, but this product component complexity, cost is higher, also need be configured during use.No. 03118164.3 disclosed controlled chlorine dioxide of solid carrier of Chinese patent and preparation technology thereof, it makes two component gelatinous mass with gel respectively with stability chlorine dioxide and acidic activator, and add a large amount of calcium salts and other materials, slow release, the controlled purpose of rate of release have been reached, but the affiliation that adds of multi-component masses causes waste, through our a large amount of studies have shown that, when material proportion is suitable, need not add calcium salt and other material, only also can reach the purpose that chlorine dioxide steadily discharges by gel-type vehicle.
Summary of the invention
Technical problem to be solved by this invention is the defective that overcomes prior art, provide a kind of preparation technology simple, easy to use, have high-efficient formaldehyde remover of air sterillization, deodorization and preparation method thereof.
The alleged problem of the present invention is solved by following technical scheme:
A kind of high-efficient formaldehyde remover, its special feature be, it is made up of A, B two components, and wherein, the A component is a chlorine dioxide matrix, and the B component is the slow release activator of living, and described A, B two components are made up of the raw material of following unit of weight respectively:
A component: sodium chlorite 0.5～10, water 40～120, agar 0.2～5;
The B component: slow release activator 0.5～18, described slow release activator are a kind of or its mixture in boric acid, citric acid, tartaric acid, oxalic acid, dihydric phosphate, sodium bisulfate, the sulfamic acid.
Above-mentioned high-efficient formaldehyde remover, described A, B two components are made up of the raw material of following unit of weight respectively:
A component: sodium chlorite 1～8, water 60～100, agar 0.5～4;
B component: slow release activator 1～15.
Above-mentioned high-efficient formaldehyde remover, described A, B two components are made up of the raw material of following unit of weight respectively:
A component: sodium chlorite 4, water 90, agar 2;
B component: citric acid 6.
A kind of method for preparing described high-efficient formaldehyde remover, it carries out according to the following steps:
A, the sodium chlorite of formula ratio is dissolved in the water of formula ratio mixing;
B, add the agar of formula ratio in above-mentioned solution, heated solution, is sub-packed in chlorine dioxide and discharges in box or other complementary tanks after agar dissolves fully to boiling, and cooling forming seals, and packing is promptly made the A component;
C, take by weighing the slow release activator of formula ratio, be sub-packed in the non-woven bag, seal, promptly make the B component.
The present invention is directed to and efficiently dispel removing residue formaldehyde problem after the interior decoration, a kind of environmental friendly indoor purified product is provided, this product is gel with agar, the chlorine dioxide matrix sodium chlorite solution is stable in the gel, be made for the A component, the slow release activator is made the B component, during use, the B component is inserted in the A component, the B component will be dissolved in the A component slowly, and reacts the generation chlorine dioxide slowly with sodium chlorite in colloid, and the part chlorine dioxide discharges from gel, evaporate in the air, PARA FORMALDEHYDE PRILLS(91,95) is dispeled.It compared with prior art has following remarkable advantage: (1) component is simple, cheap, and preparation technology realizes easily, safe in utilization effectively, do not produce secondary pollution.(2) product is stable, long shelf-life, and effect duration was above 2 years.(3) chlorine dioxide is long release time, and the chlorine dioxide that discharges is the formaldehyde in the oxidation air fast.(4) air is also had concurrently purifying functions such as sterilization, deodorization.
The specific embodiment
High-efficient formaldehyde remover of the present invention is degraded to harmful substances such as the formaldehyde in the room air, toluene by the powerful Oxidation of chlorine dioxide based on chlorine dioxide, it can be reduced to safety criterion fully.Chlorine dioxide can be killed indoor various microorganisms, also has good deodorizing effect, the atomic oxygen that it produces can become nitrogen with the ammonia dehydration, odorous gas such as hydrogen sulfide, sulfur dioxide and mercaptan are oxidized to sulphuric acid or sulfonic acid and remove, thereby become a kind of air pollution cleanser of new generation of superior performance.
Product of the present invention is formed with A, B component, the A component is a gel state, with agar is gel, and the chlorine dioxide matrix sodium chlorite solution is stable in the gel, and B component slow release activator is a powdery, be packaged in the non-woven bag, during use, the B component is inserted in the A component, the B component will be dissolved in the A component slowly, and in colloid, react the generation chlorine dioxide slowly with sodium chlorite, its reaction equation is:
5ClO
2 -+4H
+→4ClO
2+Cl
-+2H
2O
Chlorine dioxide dissolubility in gel is lower, and the part chlorine dioxide will discharge from gel, evaporate in the air, and the chlorine dioxide that discharges is the formaldehyde in the oxidation air fast, and its reaction equation is:
4ClO
2+5HCHO→5CO
2+4HCl+3H
2O
Product is carbon dioxide, water and hydrogen chloride, and hydrogen chloride can generate chloride with the carbonate continuation effect in the dust again, can not produce secondary pollution.
