A kind of slow released ClO 2 solid soap and preparation method thereof
Technical field
The present invention relates to air purification fields, more particularly, to a kind of slow released ClO 2 solid soap and its preparation side
Method.
Background technology
With the quickening of industrialized level, environmental pollution getting worse.Indoor pollutant concentration is typically the 2-5 of outdoor
Again, but the time of 70% or more the mankind is spent indoors, and the time that urban population is spent indoors has been more than 90%, baby children
The time of youngster and the old and the weak handicapped person indoors is longer, therefore keeps the cleaning of room air, removes the pollutant in room air
Influence to health is significant.The method that indoor pollution is administered mainly has bioanalysis, Physical and chemical method.Bioanalysis
Mainly by the photosynthesis of plant or the metabolism of microorganism, air, but its effect very little are purified, auxiliary can only be used as
Effect.Physical is typically the absorption property using activated carbon, adsorbs the harmful substance in air, selection of the method to pollutant
Property is small, at low cost, but belongs to passive adsorption, and activated carbon is easily saturated.Chemical method mainly has photocatalyst method, Chlorine Dioxide Method etc..
Photocatalyst is safe efficient, but its cost is higher, is limited by light.Chlorine dioxide is classified as A1 grades by the World Health Organization (WHO) and disappears
Toxic agent.It, can be by the toxic flavored substance of some in ambient enviroment, such as formaldehyde, benzene homologues, the Ammonia in family with strong oxidizing property
With the equal energy oxygenolysis such as sulphur class stink.
However ClO 2 solution using and transportational process in there are limitations, usually stablized in inertia solution or
Compound or mixture is made in the certain solid matters of person.
CN103931652A discloses following technique:Chlorite is mixed with polymerized monomer and is polymerize, high score is generated
Sub- gel, then mating acidification stick realize slow release effect, the technique is excessively complicated, needs to make two parts product respectively.
CN104719335A discloses following technique:Thickener, sustained release agent, activator are mixed to the load of viscous liquid
Body, then chlorine dioxide precursor compound is placed in carrier, which is not easy to store, transport, and production technology is equally complicated, needs
Two parts product is made respectively.
CN105145626A discloses following technique:Occur that gelling agent, sustained release agent, activation are added in object to chlorine dioxide
The cleanser of gel state is made in agent, filler etc., which is not easy to store, transport, and slow release effect is bad.
In view of this, special propose the present invention.
Invention content
The first object of the present invention is to provide a kind of slow released ClO 2 solid soap, and the solid soap solves not
Easily storage, transport, the technical problems such as slow release effect difference.
The second object of the present invention is to provide the preparation method of the solid soap, and the method and process is simple, easily
In popularization.
In order to solve the above technical problems, the present invention provides following technical schemes:
A kind of slow released ClO 2 solid soap, mainly by chlorine dioxide precursor and its activator and solid fatty acids
Salt mixes.
Existing chlorine dioxide purification product is confined to gel, there are the shelf-life it is short, be not easy storage transport, of high cost
The problems such as.The limitation has been broken in present invention innovation, is fabricated to the form of solid soap base for the first time, has both solved shelf-life, storage fortune
The problem of defeated aspect, but because materials solve the problems, such as extensively it is of high cost.
Further, since during solid fat hydrochlorate is mixed with chlorine dioxide precursor and its activator, one side itself
Crosslinking net resistance structure can be formed, one side fatty acid salt has higher affinity, therefore titanium dioxide with chlorine dioxide precursor
Chlorine precursor is can be uniformly dispersed in the cross-linked structure of soap base, and preferable slow release effect is finally presented.
Chlorine dioxide precursor of the present invention and activator are mating, and the type of chlorine dioxide precursor determines activation
The type of agent, for the purpose of it can release chlorine dioxide.
The type and content of fatty acid salt of the present invention all have a major impact slow release, shelf-life, both can be with
For single compound, or compound, compound are also not limited to the mixture of a variety of fatty acid salts, can also contain it
The accessory ingredient of its non-fat hydrochlorate.Such as:
Preferably, the fatty acid salt is the fatty acid salt of C6~C26, the preferred fatty acid salt of C12~C20, more preferably
Stearate.
Preferably, the fatty acid salt is selected from the vegetable oil of saponification, and the vegetable oil is selected from coconut oil, olive oil, palm
It is one or more in oil, palm-kernel oil, SIMMONDSIA CHINENSIS SEED OIL.
Preferably, the content of the fatty acid salt is 59~99wt%, more preferable 80~90wt%.
Chlorine dioxide precursor of the present invention can select the chlorite and/or chlorate for being easy activation, corresponding
Activator is acid.The type and content of acid influence rate of release.
Preferably, the activator is weak acid, preferably hydrophosphate, metasilicic acid, carbonic acid, organic acid, You Jiduo
It is one or more in first acid;
The organic acid is preferably the organic acid of C1~C6, a kind of or more in more preferable acetic acid, propionic acid, butyric acid
Kind;
The organic multicomponent acid is preferably one or more in citric acid, oxalic acid, tartaric acid.
Preferably, the content of the chlorine dioxide precursor is in terms of chlorine dioxide:1wt%~30wt%, more preferably
5wt%-15wt%;
Preferably, the content of the activator is 0.05-2wt%, more preferable 0.1-1wt%.
Compared with existing product, solid soap of the invention still had higher chlorine dioxide rate of release at 30 days, released
It is 30-80 days, preferably 50-80 days to put time of the rate more than 150 μ g/h.
Preferably, essence and/or edible coloring agent are also contained in raw material.Essence, edible coloring agent according to consumer groups come
Selection keeps less additive amount as possible, the feature for keeping solid soap original, safe and harmless.
The manufacture craft of slow released ClO 2 solid soap of the present invention is very simple, it is only necessary to mix this process:
According to formula feeding, the fatty acid salt is heated to molten state, is then mixed into remaining raw material, cooling to obtain the final product.
In mixed process, the concentration and pH value of chlorine dioxide precursor solution have a major impact the molding difficulty of product.
Preferably, the chlorine dioxide precursor is mixed into as a solution, and the solution containing chlorine dioxide precursor
It is dissolved in alkaline solution and being made for chlorine dioxide, pH value 8-10.
Other additives can be added on arbitrary opportunity, be preferably added after chlorine dioxide precursor, activator, improve dispersion
Degree.
Compared with prior art, invention achieves following technique effects:
(1) a kind of chlorine dioxide purification product-solid soap of neomorph is provided;
(2) the advantages of solid soap also has preferable slow release effect, and formula is simple, cost, is widely used, not only office
It is limited to be placed in the small space such as wardrobe, drawer and uses, while in combination with air cleaning facilities such as air purifier, fresh air system
Middle use;And different shaping can be made, have both aesthetics while ensureing clean-up effect;
(3) manufacture craft is very simple, industrialized production preferably.
