Description
Technical field
The invention belongs to daily-use chemical industry and field of environment protection, be specifically related to a kind of mildew-eliminating and mildew-preventing agent and remove mould mold-proof method accordingly.
Background technology
Mould is a kind of fungi the most responsive to humidity, and the change of its distribution can impact human health.Under the background that Global climate change aggravation causes zonal extreme wet weather to increase, speed and the intensity of the distribution of mould and density and its diffusion all will sharply increase, its contaminated food products medicine, the infection mankind, vegeto-animal probability also will increase greatly.Such as, the extensive fungal meningitis of U.S.'s outburst in 2012 is because medicine is subject to caused by fungal contamination.Meanwhile, the aggravation of industrial environmental pollution causes each pollutant in air to increase, and this also may provide abundant nutriment for the germination and growth of fungi.When the fungal spore in air and pollutant adhere on moist wall simultaneously, fungal spore just starts extensive germination and growth.Along with increasing gradually of the dysimmunity Diseases such as acquired immune deficiency syndrome (AIDS), malignant tumour, blood disease and diabetes, generally carrying out and the extensive use of the medicine such as broad-spectrum antibiotic, immunodepressant of the interventional technique such as organ and bone-marrow transplantation, the incidence that opportunistic pathomycete infects and lethality are at present just in the trend sharply risen.Again because the scope of activities of this type of dysimmunity Disease is generally all confined to indoor, therefore, the opportunistic pathomycete of air-conditioning and the enrichment of moist wall institute may be the important bacterial classification infecting this type of crowd.But it is but not known that these fungal colonizations sticking to germination and growth on family's air-conditioning or indoor wall form situation.
For this situation, inventor has done a series of investigation in early stage in detail.Through continuing 3 years (2010 ~ 2012), the investigation of Guangzhou, City of South China indoor wall fungi is shown, the arch-criminal of the mould grown on larger scale of extreme wet weather and the indoor wall caused due to rain leakage, air-conditioning mainly one be called ball spore cladosporium (
cladosporium sphaerospermum) filamentous fungi, the data of inventor show its ratio accounting for wall total number of fungi more than 90%.Known additionally by document both domestic and external, air, soil, the ocean mud in the front multiple place in the whole world of this Zoopagales, or even the Chernobyl Plant interior walls after having an accident is detected.Nutritional condition needed for this fungi is very low, and germination and growth ability is strong, can survive under the environment of various adverse circumstances or even high radiation.The investigation in early stage of inventor also finds, once wet weather arrives, this bacterium just infects the body of wall made moist very easily on a large scale, forms dark-coloured mildew.In addition, medical literature was had to report in the past, ball spore cladosporium (
c. sphaerospermum) belong to opportunistic pathogenic bacteria, once it sharply increases in the density of indoor, likely higher infection risk will be caused to the crowd of hypoimmunity; Over nearly 5 years, there are many sections of domestic and foreign literature follow-up stories, claimed it can infect blood, cornea, lung, skin etc.Up-to-date research display in 2012, after it is infected mouse by external wounds or intravenous injection, can cause the organs infection of the general of mouse, thus in three days, cause test mice half dead.In addition, inventor find in the investigation process to wall and air-conditioning fungal colonization dendritic cladosporium (
cladosporium cladosporioides) be also the important component part of this fungal colonization, and after being separated further, find that its germination and growth ability even exceedes ball spore cladosporium.Numerous document display, dendritic cladosporium is also a kind of opportunistic pathomycete extensively existed in soil, air and rotten fruit and food, human body because of immunity degradation or because of skin injury be in contact with it after then have infected chance, now main common with skin infection, also there is the report of brain infection, lung fungal ball, root of the tooth granuloma periapicale, fungal infection of nail.Unfortunately, body of wall mildew-eliminating and mildew-preventing agent before not for the ball spore cladosporium had comparative advantage on indoor wall (
c. sphaerospermum) and occupy a certain proportion of dendritic cladosporium (
c.cladosporioides) do relevant application study, and mildew-eliminating and mildew-preventing agent before mainly adopts containing benzene compound, hypochlorous acid, hypochlorite, acylate etc. as removing mildew-resistant composition, although successful, but its taste is large, easy volatilization, poor stability, has a certain impact to human body especially eyes and respiratory tract, and can only smear, can not accurately spray; Certainly, also there is the mildew removing agent using plant concentrated extract as antipathogenic composition recently, but its complicated component, and antifungal mechanism is not too distinct, and do relevant application study for indoor dominant ball spore cladosporium equally.
Summary of the invention
An object of the present invention is for above-mentioned the deficiencies in the prior art, a kind of safe and efficient economical and practical mildew-eliminating and mildew-preventing agent is provided, it can by mouldy or have the mould of the body surface of mouldy risk to kill, and can the sprouting of mould fungus inhibition spore efficiently and growth when lasting high humility and high nutrition.
Another object of the present invention is to provide corresponding except mould mold-proof method.
For achieving the above object, the technical solution used in the present invention is as follows.
A kind of mildew-eliminating and mildew-preventing agent, it contains mass percent is the potassium sorbate of 0.1% ~ 2% and the sorbic acid of 0.1% ~ 2%, and solvent is water and ethanol.
A kind of mildew-eliminating and mildew-preventing agent, it contains mass percent is 0.4% ~ 2%(preferably 0.6 ~ 2%) potassium sorbate, solvent is water.
A kind of mildew-eliminating and mildew-preventing agent, it contains mass percent is 0.4% ~ 2%(preferably 0.6 ~ 2%) sorbic acid, solvent is ethanol.
The great many of experiments display of inventor's design, when the concentration of potassium sorbate, sorbic acid reaches 0.4% respectively, or when when both mix, respective concentration all reaches 0.1%, even if at nutritious (2% glucose+2% peptone+1% yeast extract) and humidity higher (humidity ≈ 90%), still can continue to suppress completely " infect the main advantage fungi of indoor wall and air-conditioning---ball spore cladosporium (
cladosporium sphaerospermum) " sprouting and growth.Potassium sorbate is highly stable, and difficult volatilization, just starts after attachment to play bacteriostasis.And potassium sorbate is one of the most efficient current safest foodstuff broad-spectrum preservative of international food and agricultural organization and Health Organisation recommendations, colourless odorlessness, it can be absorbed by the metabolic system of human body and be decomposed into rapidly carbonic acid gas and water.And sorbic acid also has similar character.Therefore, be potassium sorbate or the sorbic acid of 0.4% ~ 2% containing mass percent, or simultaneously containing 0.1% ~ 2% potassium sorbate and the mildew-eliminating and mildew-preventing agent of sorbic acid can the Growth and reproduction of effective mould fungus inhibition.This concentration had both met medicine food safety standard, at utmost can exercise mildew-proof function again.
In order to reach except mould effect, preferably, also oxidant is contained in above-mentioned mildew-eliminating and mildew-preventing agent.By oxidation reaction, effectively can remove the mould being originally attached to body surface, and the existence of potassium sorbate or sorbic acid can prevent attachment again and the growth of mould.
Above-mentioned oxidant is preferably hydrogen peroxide.Hydrogen peroxide has oxidation bleaching effect, and it is conventional food-grade oxidant and pharmaceutical grade disinfectant, is finally transformed into water and oxygen, harmless.The hydrogen peroxide of the efficient oxidation amount is sprayed onto on mouldy object after 15 to 30 minutes, namely can by ball spore cladosporium (
c. sphaerospermum) and/or dendritic cladosporium (
cladosporium cladosporioides) the more shallow dark-coloured mildew that formed is oxidized to white, thus blocks the approach of the fungal infection mankind, also can keep the attractive in appearance of white room wall simultaneously.
The mass percent of above-mentioned hydrogen peroxide is preferably 2 ~ 6%.The hydrogen peroxide of this concentration range is while effectively removing mould, and its spraying formed can not impact human body skin, does not almost have peculiar smell in sprinkling process.
Further, various auxiliary agent can be added in the solution of the potassium sorbate containing above-mentioned concentration and/or sorbic acid, to reach the effect of various needs, such as antioxidant and anti-oxidant synergist, drier, bactericide, coverture, antibacterial synergist and stabilizing agent.Antioxidant can protect potassium sorbate and sorbic acid, reduce its speed that is oxidized by various oxidant, can add when needs long term storage.For security consideration, the preferred China GB2760-1996 of antioxidant of the present invention specifies the foodstuff antioxidant allowing to use, and comprises butylated hydroxy anisole (BHA), dibutyl hydroxy toluene (BHT), D-sodium isoascorbate, Tea Polyphenols, phytic acid, ditert-butylhydro quinone (TBHQ), Licorice root antioxidant, Calcium Ascorbate, cephalin, ascorbyl palmitate, coloured glaze for one or more in dipropionic acid two lauryl, 4-hexyl resorcin, ascorbic acid and Rosmarinus officinalis extract.Multiple antioxidant adds simultaneously can play collaborative antioxidation, and its total concentration is preferably 0.01% ~ 0.02%.Wherein, dibutyl hydroxy toluene (BHT), D-sodium isoascorbate, ditert-butylhydro quinone (TBHQ), coloured glaze are white powder for dipropionic acid two lauryl, 4-hexyl resorcin, vitamin C (ascorbic acid) VitaminC and ascorbyl palmitate, therefore when using white wall, preferably these antioxidants.Other antioxidant has light yellow (phytic acid) and light green color (Tea Polyphenols), can use on the wall of similar color.In addition, also anti-oxidant synergist can be added, it is preferably ethylenediamine tetra-acetic acid (the Ethylene Diamine Tetraacetic Acid) EDTA that concentration is 0.005% ~ 0.01%, though it can not directly prevent oxidant by potassium sorbate and sorbic acid oxidation, but but can generate complex compound with the trace metal ion of accelerating oxidation, make metal ion lose the effect of accelerating oxidation.Drier can accelerate the rate of drying after spray use, prevents mould from utilizing the moisture in spray to carry out germination and growth.Drier can be medical ethanol, mixes as solvent, can either volatilize its ratio with water using 7 to 3 fast after spray coating, can also exercise the effect of kill bacteria as bactericide.Coverture can help to cover the darker mould contamination region being not easy oxidized bleaching of some colors, and it can be the calcium carbonate of 0.2% ~ 0.5% for mass percent.In addition, because hydrogen peroxide only has when its pH value is just the most stable 3.0 ~ 4.5 time, therefore add stabilizer of hydrogen peroxide can prevent from the hydrogen peroxide in solution and other all kinds of material from reacting in the process of preserving for a long time losing efficacy, it can add final concentration is that the hydrochloric acid of 0.001mol/L is as stabilizing agent.The hydrochloric acid of above-mentioned stabilizer of hydrogen peroxide---0.001mol/L equally also has the effect of calcium carbonate chaotropic agent and the antibacterial synergist of potassium sorbate.Because coverture calcium carbonate can (pH3 ~ 5) form calcium bicarbonate and dissolve in water under mild acid conditions, the antibacterial efficiency of potassium sorbate (pH3.0 ~ 4.5) in acid condition also can increase by 2 ~ 3 times relative under neutrallty condition.
In above-mentioned mildew-eliminating and mildew-preventing agent, the solvent of potassium sorbate and hydrogen peroxide can select aqua sterilisa or ordinary tap water, is conveniently easy to get and safe and harmless.And the solvent of sorbic acid can select medical ethanol.
Above-mentioned mildew-eliminating and mildew-preventing agent can make paint or spray, keeps in Dark Place in dark sealed glass container, to prevent its oxidized inefficacy.When making spray, sorbic acid and/or potassium sorbate and hydrogen peroxide are dissolved in a certain proportion of water and/or alcohol mixed solvent, loaded in the spray bottle of sealing afterwards, for accurately spraying with except killing and preventing mold colony to grow.Preferably, potassium sorbate and/or sorbic acid can be configured to A liquid, and add antioxidant (such as phytic acid), its preferred concentration is 0.01% ~ 0.02%; Meanwhile, hydrogen peroxide is configured to separately B liquid, and adds stabilizer of hydrogen peroxide---the hydrochloric acid of 0.001mol/L.Mixed by A, B liquid before use, to avoid in the process deposited, hydrogen peroxide is by potassium sorbate and sorbic acid oxidation.
The present invention also provides a kind of corresponding except mould mold-proof method, smears or be sprayed at body surface by above-mentioned mildew-eliminating and mildew-preventing agent.When the water loading of the sorbic acid and/or potassium sorbate that are dissolved with valid density is mould or after having played mould place to easily rising, along with the evaporation of moisture and ethanol, sorbic acid and/or potassium sorbate just stick to the surface in these places or inlay therein, thus suppress the germination and growth of next round mycotic spore constantly.
Preferably, above-mentioned body surface is because ball spore cladosporium causes mouldy surface.Due to the specific aim of potassium sorbate, to ball spore cladosporium (
c. sphaerospermum) and/or dendritic cladosporium (
cladosporium cladosporioides) cause mouldy except mould anti-mold effect best.

Embodiment
embodiment 1
In order to check and compare potassium sorbate, sorbic acid and both mixtures under high nutrition and high humidity to wall Superior fungus---ball spore cladosporium (
c.sphaerospermum) and dendritic cladosporium (
cladosporium cladosporioides) inhibition, inventor has prepared a series of enrich media, the concentration gradient of the potassium sorbate wherein arranged, sorbic acid and potassium sorbate and sorbic acid mixture (concentration of sorbic acid and potassium sorbate respectively accounts for half) is 0%, 0.08%, 0.1%, 0.15%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%.Numerous document display, dendritic cladosporium is also a kind of at wall, air-conditioning, soil, the opportunistic pathomycete extensively existed in air and rotten fruit and food, human body because of immunity degradation or because of skin injury be in contact with it after then have infected chance, common with skin infection, also brain is had to infect, lung fungal ball, root of the tooth granuloma periapicale, the report of fungal infection of nail, inventor finds that in the investigation process to wall and air-conditioning fungal colonization it is the important component part of this fungal colonization, and after being separated further, find that its germination and growth ability even exceedes ball spore cladosporium.Therefore, inventor selects this bacterium together with ball spore cladosporium as experimental subjects, it can be used as the bacterial strain detecting potassium sorbate and sorbic acid and composition thereof bacteriostasis efficacy.The spore of excessive ball spore cladosporium and dendritic cladosporium is all spread evenly across on medium respectively, be placed in 25 DEG C, humidity be 90% mold incubator cultivate, and continue observation fungus growth situation.
Result as shown in Figure 1.By contrasting the growing state of the 6th day, inventor finds, when the concentration of potassium sorbate or sorbic acid reaches or surpasses 0.4% respectively time, flat board does not just have completely ball spore cladosporium (
c. sphaerospermum) grow, when the concentration of potassium sorbate or sorbic acid reaches or surpasses 0.6% respectively time, flat board does not just have completely dendritic cladosporium (
c.cladosporioides) grow.But, find in the comparative trial of carrying out at the same time, if potassium sorbate and sorbic acid are mixed with isoconcentration, then when the total concentration of potassium sorbate and sorbic acid mixture reaches or be greater than 0.15% (when the concentration of potassium sorbate and sorbic acid reaches or surpasses 0.075% respectively), ball spore cladosporium on flat board (
c. sphaerospermum) just receive suppression completely; Meanwhile, when the total concentration of potassium sorbate and sorbic acid mixture reaches or is greater than 0.2% time (when namely the concentration of potassium sorbate and sorbic acid reaches or surpasses 0.1% respectively), dendritic cladosporium on flat board (
c.cladosporioides) just receive suppression completely.Afterwards, under keeping this temperature and humidity condition, continue to be cultured to the 30 day, the flat board of this concentration does not still have bacterium colony grow, this shows under the concentration being more than or equal to 0.15%, the mixture of potassium sorbate and sorbic acid just can reach to ball spore cladosporium (
c. sphaerospermum) fully effective suppression, this illustrates that the minimum complete Mlc of this mixture will be at half than the minimum complete Mlc being used alone potassium sorbate or sorbic acid; Similar, when total concentration is greater than or equal to 0.2%, potassium sorbate and sorbic acid mixture just can reach to dendritic cladosporium (
c.cladosporioides) fully effective suppression, the minimum complete Mlc of this mixture is lower by 2/3rds than the minimum complete Mlc being used alone potassium sorbate or sorbic acid.Therefore, according to the suppression situation of two kinds of cladosporiums, potassium sorbate and sorbic acid all can effectively suppress the growth of these two kinds of cladosporiums to be sprouted; Make us more interested, if by potassium sorbate and sorbic acid mixing, then improve 1 ~ 2 times than its fungistatic effect be used alone.Therefore, inventor thinks potassium sorbate and sorbic acid antibacterial synergist each other.
embodiment 2
In order to detect potassium sorbate effect in actual applications further, inventor with 0.4% potassium sorbate aqueous solution immersion treatment white gypsum head portrait, afterwards, be placed on shallow-layer containing ball spore cladosporium (
c. sphaerospermum) and dendritic cladosporium (
c.cladosporioides) eutrophy liquid nutrient medium in 30 days.Result is as shown in Figure 2, still fair and clear as new with the white gypsum head portrait (code name is G+ and W+) of potassium sorbate process, can't be subject to the pollution of ball spore cladosporium and dendritic cladosporium.But in the check experiment of synchronously carrying out, the white gypsum head portrait (code name is G-) not with potassium sorbate process is placed in shallow-layer and contains the eutrophy liquid nutrient medium of mould after 30 days by inventor, its surface can be subject to ball spore cladosporium (
c. sphaerospermum) from bottom to up in the pollution of spreading trend.
