Description

A kind of medicinal air freshening bactericide
Technical field
The present invention relates to a kind of disinfection sanitizer, specially a kind of medicinal air freshening bactericide.
Background technique
In the interior space of family, hotel, office building, school, hospital, dining room, KTV parlor, station, Hou Jilou etc., The cleaning of air directly affects people's health, it is therefore desirable to regularly be sterilized, be sterilized to indoor environment, to ensure interior Environmental sanitation, cleaning prevent occupant or the public from being influenced by the infringement of the morbid substances such as toxic and harmful gas or virus Health or disease.Existing disinfection of indoor air method mainly useful atomizers spray thimerosal or uses thimerosal Directly indoor article is wiped;Or use air cleaner, by indoor carry out circulating filtration and through ultraviolet light or Thimerosal carries out biocidal, and used thimerosal is mostly Peracetic acid.
Chlorine dioxide is a kind of internationally recognized efficient, nontoxic, quick, spectrum disinfection sanitizer, it is to bacterium, true Bacterium, virus, gemma have 100% sterilization effect, and sufficient concentrations of chlorine dioxide need to be only contained in specified air, can be passed through Its strength oxidation kills various microorganisms therebetween, and to harmful substances such as formaldehyde, benzene, toluene in room air There is degradation.Chlorine dioxide has good deodorizing effect, and ammonium hydroxide can be dehydrated and become nitrogen by the atomic oxygen that it is generated, The odorous gas such as hydrogen sulfide, sulfur dioxide and mercaptan are oxidized to sulfuric acid or sulfonic acid and are removed, to become a kind of superior performance Air pollution cleanser of new generation.
But since chlorine dioxide is gas, property is unstable, it has not been convenient to store, greatly limit chlorine dioxide as empty Hopping mad bacterium, disinfectant widespread adoption, there is presently no storage, chlorine dioxide air easy to use sterilize freshener.
Summary of the invention
To solve the above existing issue, the present invention provides a kind of medicinal air freshening bactericide.The present invention passes through following technical side Case is realized.
A kind of medicinal air freshening bactericide, formula are formulated by following parts by weight substance:

The stabilizer is one or more of sucrose ester, gluconic acid, sodium gluconate, glucolactone;
The filler is one of calcium carbonate, sodium sulphate, barium sulfate, beta-cyclodextrin, sodium bicarbonate or a variety of compositions Mixture.
Most preferably, preparation method includes the following steps:
(1) each constitutive material that corrresponding quality part is weighed by formula ratio is respectively put into baking oven drying, spare;
(2) chlorine dioxide precursor and stabilizer are stirred, adds sustained release agent and is uniformly mixed so as to obtain mixture A powder End;
(3) gelling agent and filler are uniformly mixed, aromatic is added and mixes, obtains mixture B powder;
(4) deionized water will be added in mixture B powder, stirs evenly;Mixture A powder is added to stir evenly, then plus Enter activator stirring, obtains final sterilizing and air freshener.
Beneficial effects of the present invention:
A kind of medicinal air freshening bactericide of the present invention is a kind of sustained-release chlorine dioxide gel shape product, in stable condition in use, Release chlorine dioxide speed can be regulated and controled according to the type that sustained release agent is added, and be suitble to the sterilizing of a variety of occasion air.This It joined aromatic in invention formula, increase and de-taste effect, improve human feeling, be that safely and effectively air disinfection disappears one kind Toxic agent.
