Description
Technical field
The invention belongs to antibiosis and sterilization agent technical field, be specifically related to chlorine dioxide generating agent of a kind of unitary packaging and preparation method thereof.
Background technology
Chlorine dioxide is a kind of novel disinfectant, and be a kind of water-soluble strong oxidizer, oxidability is 2.63 times of chlorine, there is efficient sterilizing ability and decolouring and deodorizing function, the bacterium in water body and gas can be killed, and carcinogenic, teratogenesis can not be produced and cause projecture matter, be therefore widely applied in developed country.Disinfection agent of chlorine dioxide by internationally recognized be function admirable, effective disinfection sanitizer, food preservative and water quality cleansing agent.
At present, the preparation method of chlorine dioxide mainly comprises chemical method and electrolysis two kinds of methods, and wherein chemical method can be divided into again sodium chlorite method and sodium chlorate method.With sodium chlorite (NaClO
2) mainly contain acidization, chlorine oxidation process, persulfuric acid radical ion oxidizing process, electrochemical process, organic matter and transiting metal oxidation method for raw material produces the method for chlorine dioxide, wherein react for hydrochloric acid and sodium chlorite and prepare chlorine dioxide, its cardinal principle is: 5NaClO
2+ 4HCl=4C1O
2↑+5NaCl+2H
2o.But the method due to reaction in needed for acid be liquid acid, therefore use inconvenience, and there is certain danger.
At present, when production solid chlorine dioxide release agent, major part sodium chlorite and solid acidifier is separated to pack, and prevents it from just reacting before use, and release chlorine dioxide, causes product failure.But this two-component packaging use procedure more complicated, needs during use to allocate according to ratio, and general two-component packaging disinfectant needs to render in water and to react or its acidulant is liquid acid.
Publication number be CN101176469A patent document discloses a kind of disinfection agent of chlorine dioxide and preparation method thereof, comprise stabilizing agent and activator, described stabilizer package is containing sodium chlorite 62 ~ 74%, sodium chloride 8 ~ 12%, sodium bicarbonate 7 ~ 11%, calcium chloride 2 ~ 2.5%, sodium carbonate 7.5 ~ 11.5%, and activator is the hydrochloric acid that concentration reaches 4 ~ 6%.This disinfectant needs two-component packaging equally, needs stabilizing agent and activator to add use simultaneously, carries inconvenience.
The direction of present research is changed to unitary packaging by two-component packaging gradually, and therefore disinfection agent of chlorine dioxide has occurred comprising the types such as unitary powder packaging, unitary tablet and unitary granule.But produce the reaction condition that a unitary packaging solid chlorine dioxide disinfectant difficult problem is to need to control sodium chlorite and solid acidifier, and suitable solid acidifier and passivator, after making it mix with sodium chlorite, do not react under non-usage condition, and need only need change condition and can directly react without the need to additional reactant when using.
Publication number be CN1439268A patent document discloses a kind of solid state stability disinfection agent of chlorine dioxide, it adopts organic polymer to carry out coated to sodium chlorite, obtained coated parent, with anhydrous magnesium sulfate and calcium chloride, Passivation Treatment is carried out to coated parent again, finally mix with composite exciting agent, achieve the isolation passivation of material in packaging bag, during use, disinfectant is dissolved in the water.But this disinfectant needs to use a large amount of anhydrous magnesium sulfate and calcium chloride as passivator in manufacturing process, nullified composition increases, cause the increase of cost, and must be thrown in water when using this disinfectant, just can discharge chlorine dioxide, thus limit the range of application of this disinfectant.
The preparation method that patent document discloses a kind of chlorine dioxide generating agent of publication number CN1449991A, comprise: after sodium chlorate or sylvite, solid acid, water absorbing agent, catalyzer and stabilizing agent are mixed, make granule, pulvis or tablet, very easy to use.The weak point of the method is: can produce CO in course of reaction
2although, CO
2certain effect is produced to preservation, but works as CO
2too high levels, will suppress fruits and vegetables respiration.
Publication number is the preparation method that patent document discloses a kind of chlorine dioxide generating agent of CN101172579, comprising: after 1:1 ~ 1:20 mixes in mass ratio with citric acid by sodium chlorite, then this chlorine dioxide generating agent is prepared into pulvis or tablet.This chlorine dioxide generating agent is easy to carry, be applicable to family and use of sterilizing among a small circle, but composition forms simple, and have hygroscopy due to sodium chlorite and citric acid, if directly sodium chlorite and citric acid are mixed, make tablet or powder, be easy to make sodium chlorite and citric acid to lose efficacy after moisture absorption in atmosphere.
Summary of the invention
