Abstract

The invention discloses a chlorine dioxide air disinfectant which comprises the following components in parts by weight: 5-10 parts of chlorite, 5-10 parts of an acid form agent, 70-85 parts of an auxiliary agent and 5-10 parts of an aromatic; a method for preparing the chlorine dioxide air disinfectant comprises the steps of S1, respectively drying the chlorite, the acid form agent, the auxiliary agent and the aromatic by a hot air drier; S2, grinding and sieving the dried chlorite, acid form agent, auxiliary agent and aromatic; and S3, evenly mixing according to a formula in an oxygen-free environment, and respectively packaging by boxes. The chlorine dioxide air disinfectant is box-packed powder; after being contacted with air, the chlorine dioxide air disinfectant is capable of continuously releasing chlorine dioxide gas, so that the continuous dynamic purification is carried out on the air, and harmful chemical substances in the air can be decomposed; the chlorine dioxide air disinfectant prepared by adopting the method is convenient to use and fragrant in smell, and has the effects of efficient sterilization and deodorization.

Description

A kind of ClO 2 air disinfectant and preparation method thereof
Technical field
The present invention relates to a kind of air sanitizer and preparation method thereof, belong to gas depoisoning technical field.
Background technology
The interior space at family, hotel, office building, school, hospital, dining room, KTV parlor, station, Hou Jilou etc., the cleaning of air directly affects people's health, therefore need to indoor environment, carry out sterilization, sterilization termly, to guarantee indoor environmental hygiene, clean, prevent that occupant or the public are subject to the infringement of the morbid substances such as toxic and harmful or virus and affect healthy or suffer from disease.Existing disinfection of indoor air method mainly contains with atomizers spray thimerosal or with thimerosal directly carries out wiping to indoor article; Or use air cleaner, by carrying out circulating filtration and carry out biology through ultraviolet ray or thimerosal and kill indoor, and the thimerosal using mostly is Peracetic acid.
Chlorine dioxide is a kind of disinfection sanitizer of internationally recognized efficient, nontoxic, quick, spectrum, it has 100% sterilization effect to bacterium, fungi, virus, gemma, in specifying air, only need contain the chlorine dioxide of enough concentration, can kill various microorganisms therebetween by its powerful oxidation, and the harmful substances such as the formaldehyde in room air, benzene, toluene are had to ideal degradation, can be reduced to safety standard completely.Chlorine dioxide has good deodorizing effect, the atomic oxygen that it produces can become nitrogen by ammoniacal liquor dehydration, the odorous gas such as hydrogen sulphide, sulphur dioxide and mercaptan are oxidized to sulfuric acid or sulfonic acid and remove, thereby become a kind of air pollution clarificant of new generation of superior performance.But because chlorine dioxide is that a kind of gas and its aqueous solution are unstable, chlorine dioxide is volatile, easily from the aqueous solution, with gaseous form, evaporate, in addition due to chlorine dioxide, there is the feature of extremely strong oxidisability and easy optics decomposition, accumulating difficulty, therefore up to the present its as bactericide, to be applied to disinfection of indoor air still very limited.
Chinese patent ZL200710062147.3 has announced a kind of aromaticity Chlorine dioxide air sterilization tablet and preparation method thereof, two yuan of tablets that it is comprised of A tablet and B tablet, A tablet comprises chlorine dioxide matrix, covering, binder, lubricant releasing agent, acidic materials; B tablet comprises blowing agent, binder, lubricant releasing agent, solid irreducibility spices powder.Though this invention has overcome conventional method, first make active aqueous solution of chlorine dioxide recycling ultrasonic atomization technology or directly the chlorine dioxide stripping in solution gone out and entered air inconvenient problem with use, but owing to being A, two kinds of agent sheets of B, during use, first water dissolves A sheet, after question response is complete, put into again B sheet, use or inconvenience.
Summary of the invention
The shortcoming that the object of the invention is to overcome prior art, provides a kind of ClO 2 air disinfectant and preparation method thereof, and the ClO 2 air disinfectant that adopts the method to prepare is easy to use, fragrant odour, has the effect of efficient sterilizing, sterilization, deodorizing.
Object of the present invention is achieved through the following technical solutions: a kind of ClO 2 air disinfectant, and it is comprised of the component of following weight portion:
