Abstract
The present invention relates to a kind of tableware washing, disinfectant product of being specially adapted to.It mainly is to adopt alkali metal hydroxide to guarantee pH 〉=10.8 of the aqueous solution of decontaminant 1%, and uses alkalimetal silicate, alkaline carbonate synergy simultaneously except that alkaline metal hypochlorite, alkylbenzene sulfonate are arranged.It is a kind of be again a kind of fabulous washing composition, and cost is low to hepatitis B virus and the special effective disinfectant of virus of AIDS, good stability, production technique is simple.
Description
The present invention relates to a kind of tableware washing, disinfectant product of being specially adapted to.
In the prior art, be used for tableware washing, the disinfectant product category is a lot, conclude to get up mainly to form by the no machine aided desalinization of soil by flooding or leaching, chlorinated product-sterilizing agent and tensio-active agent-washing composition.By its composition, the two big classes that generally can be divided into commonly used, a class be contain phosphoric, a class is liquid or the powdered detergent that does not contain phosphoric.But all there is ecological problem in all kinds of decontaminants that contain phosphoric, produce eutrophic pollution, and price is also relatively more expensive.
As phosphorated liquid cleaning and sanitizing agent not, in EP142197, introduced a kind of detergent bleach agent, mainly by 2～16% alkaline metal hypochlorite, materials such as 0.05%～3% alkylbenzene sulfonate aniorfic surfactant and a certain amount of defoamer-fat tertiary alcohol mix for it.Weak point this and even employed all kinds of decontaminants at present is: 1. the pH value of decontaminant 1% aqueous solution is all lower, and the 250PPm available chlorine that is difficult to reach the promulgation of China Ministry of Health was killed the use standard of hepatitis B virus and virus of AIDS within 5 minutes.2. less stable, easily degraded.3. under comparatively high temps (60～80 ℃) cleaning function is preferably arranged, washing effect is bad at normal temperatures, and the tableware of the greasy pollution of counterweight can not clean up very soon, after must cleaning with washing composition earlier, and row sterilization again, very inconvenient.4. cost height, be generally 2.8 yuan～more than 6 yuan/kilogram, be difficult to apply.
The objective of the invention is to avoid above-mentioned weak point of the prior art and provide under a kind of working conditions that meets China Ministry of Health regulation, can kill hepatitis B virus and virus of AIDS fully, phosphorated does not have sterilization and cleaning function, and the tableware decontaminant product of good stability.
Can reach purpose of the present invention by following measure: in the decontaminant except that alkaline metal hypochlorite, alkylbenzene sulfonate aniorfic surfactant are arranged, (as follows) also has 4.0～6.0% alkali metal hydroxide by weight, 2.0 the gross weight that～9.0% alkalimetal silicate, 2.0～9.0% alkaline carbonate and silicate, carbonate add together is 11%; And the consumption of alkaline metal hypochlorite's aqueous solution is 40～60%; The consumption of alkylbenzene sulfonate is 5～12%.Surplus is water, stopping composition, spices, tinting material etc.Its core is to guarantee PH 〉=10.8 of decontaminant 1% aqueous solution, and uses alkalimetal silicate, carbonate synergy simultaneously.Do not adopt phosphoric acid salt and contain the material of phosphoric.
The oxyhydroxide of alkali metallic sodium, potassium, lithium etc. all can meet the demands, to guarantee the pH value of the decontaminant aqueous solution.The present invention adopts the sodium hydroxide that cheaply is easy to get.
Alkalimetal silicate can be the liquid or solid of water glass, potassium silicate etc.It is SiO that the present invention adopts water glass and modulus
2: Na
2O be 3.3: 1 to 2: the 1(mole ratio).
Alkaline carbonate is a yellow soda ash, also can adopt salt of wormwood, Quilonum Retard.
The alkaline metal hypochlorite is the aqueous sodium hypochlorite solution of available chlorine content greater than 40 grams per liters, to guarantee that available chlorine content is greater than 1.5% in the decontaminant.
Alkylbenzene sulfonate is the solid or the liquid of Sodium dodecylbenzene sulfonate.
More than used material be the general industry product entirely, all can buy in the chemical industry shop.
Below in conjunction with embodiment content of the present invention is done further to comment.
Example 1, batching consumption (gram) are annotated
Sodium hydroxide 27
Water glass 75 strength of fluids 40 Baumes, modulus 3.1
Yellow soda ash 25
Clorox 250 available chlorine contents＞80 grams per liters
The aqueous solution
Sodium dodecylbenzene sulfonate 175 agent content 30 ± 1% alive

The preparation method is: earlier that sodium hydroxide is soluble in water, add water glass, and mix; Add yellow soda ash again, when the temperature that is mixed into mixture drops to envrionment temperature, add clorox and be mixed into yellow soda ash and dissolve fully; Add Sodium dodecylbenzene sulfonate at last, mix and promptly obtain decontaminant of the present invention.
For under Ministry of Health's defined terms, killing the hepatitis B virus that contains 10% normal human serum fully, find through experiment, the PH of the used decontaminant aqueous solution must be greater than 10.8, this may be because serum and hepatitis virus all are made up of protein, and the cause of alkaline aqueous solution energy protein hydrolysate.Comparatively ideal alkaline matter is alkali-metal oxyhydroxide, and (in the example 1) selects the sodium hydroxide that accounts for gross weight 4.6% for use here.Because therefore it has stronger cleaning function for its energy saponification greasy dirt and protolysate dirt, but also is the stablizer of clorox.When consumption surpasses 6.0%, that its sterilisation effect increases and not obvious.
Water glass is in the same place with yellow soda ash is composite, has the effect of collaborative washing, and promptly both composite cleaning functions together are greater than both independent cleaning function sums.And the compound of water glass and yellow soda ash also has synergistic function, the promptly remarkable disinfecting power that increases the sterilization composition.
Example 2, batching consumption (gram) is annotated
Sodium hydroxide 27
Water glass 100 is with example 1
Yellow soda ash 0
Clorox 250 is with example 1
Sodium dodecylbenzene sulfonate 175 is with example 1
Water 33

The difference of example 1 and example 2 is to have or not in the decontaminant solution compound of water glass and yellow soda ash, and they are compared as follows 2 minutes the killing effect of hepatitis B toxic action that contains 10% normal human serum:
2 minutes action time of effective chlorine density (PPm)
Example 1 example 2
500 effectively
250 effectively do not kill fully
125 enabledisables
62.5 it is invalid not kill fully
31.5 it is invalid not kill fully
The minimum effective chlorine density of decontaminant that water glass and yellow soda ash compound be described during for 125PPm effect 2 minutes effective.
The method that detects hepatitis B virus is a solid-phase radioimmunoassay.
The enzyme marking reagent medicine box is a U.S. Abbott company product.
ANSR counter with U.S. Abbott company is surveyed the CPm value.
" effectively " expression is killed fully.
China Ministry of Health regulation: effective chlorine density is not more than 250ppm, is not more than 5 minutes action time, and it is just effective to killing hepatitis B virus at last to kill the hepatitis B virus that contains 10% normal human serum fully.
The consumption of water glass and yellow soda ash compound is that the consumption that both add together is about 11% of a decontaminant gross weight, and both composite ratios are that water glass yellow soda ash (weight ratio) equals 0.22 to 4.5, are preferably about 1.Ratio between two was less than 0.22 o'clock, and yellow soda ash is difficult for dissolving and easily is the Sodium carbonate decahydrate crystallization separating out.Water glass also has following function simultaneously: preventing that 1. clorox from decomposing, is that clorox decomposes, and is effective stablizer of clorox.2. buffer reagent makes decontamination solution keep certain pH value, and unlikely chance acidic substance lost efficacy.3. anticorrosive agent, it can form layer protecting film on the surface of washings, prevent the corrosion of other chemical substance to the surface.
Tensio-active agent is the washing composition in the tableware decontaminant.Only tensio-active agent is the aniorfic surfactant Sodium dodecylbenzene sulfonate, and its structural formula is:
Its outstanding advantage be can anti-clorox oxygenizement, do not influence the stability of clorox, but also have disinfection.If employed tensio-active agent is resistance to oxidation not, decomposed by chlorinated product or oxygen preparation, also just consumed chlorinated product or oxygen preparation simultaneously, to the poor stability that makes decontaminant.The consumption of Sodium dodecylbenzene sulfonate is 5～12%, is preferably 9%.When consumption was lower than 5%, the washing effect of decontaminant was poor, was higher than at 12% o'clock, and it is not obvious that washing effect increases.
Chlorinated product is the sterilization composition in the decontaminant, selects for use aqueous sodium hypochlorite solution as chlorinated product here.To liquid cleaning and sanitizing agent, it can directly be used for composite, need not through dissolving, and the aqueous sodium hypochlorite solution cost is low, wide material sources.Its consumption is 40～60%, to guarantee to have in the decontaminant available chlorine content greater than 1.5%.Consumption is that 42.7% effect is better in the example 1.
Example 1 decontaminant is to the killing effect of virus of AIDS.
