Description
Technical field
The invention belongs to antibiotic and sterilizing fields, and in particular to the medicine of the electronic equipments such as a kind of pair of mobile phone progress cleaning and sterilizing
Liquid.
Background technique
With the progress of science, almost everyone is owned by mobile phone now, according to International Telecommunications Union in a few days
The annual flagship report of watt general headquarters publication, global mobile phone user have covered 95% or more world population close to 7,100,000,000.China
Mobile phone user's quantity is equally up to 12.56 hundred million people, and the people for being equivalent to China 90.8% is using mobile phone.
Growing day by day with smart phone quantity, mobile phone is more firm as the status of the first big access terminals equipment,
And mobile phone habituationization is got worse with becoming younger.People are at table, walk, usually residence man, party of going out, all make in life
With mobile phone, more and more people become bow race, mobile phone party.It is average weekly, user is up to 1500 times using the frequency of mobile phone, often
It is subtracted except sack time, about the time of a quarter use mobile phone, to complete from mail to play game to
The a series of task such as hair-like state.
However, everybody knows little about it, this mobile phone used everyday has become the breeding base of a large amount of bacteriums, threatens strong
Health.The bacterium carried on mobile phone mainly has four classes, is staphylococcus epidermis, staphylococcus aureus, Escherichia coli (Salmonella
Bacterium) and bacillus.When making a phone call these wriggle bacterium inevitably can by positions such as erasings to face, may cause dark sore,
Pneumonia, meningitis etc.；The infection problems of mobile phone are on the rise, and the cross-infection of mobile phone even has become the important of nosocomial infection
Reason." stealth " microbes on mobile phone constitute a threat to people's health, and the infection of mobile phone can expand the propagation of microorganism
A possibility that range, increase cross-infection and potential risk, while increasing what microbial infection propagation, prevalence and generation newly made a variation
Chance brings great challenge to society.
Currently, rarely have both at home and abroad for the dedicated disinfectant of the electronic equipments such as mobile phone, also most that is circulated on the market
It is all the basic cleaning agent without sterilizing effect.In common in low effect disinfectants, biguanides and quaternary ammonium disinfectant
Long sterilizing time, slow effect；Ethyl alcohol does not have lasting sterilizing ability then, i.e. without bactericidal effect after volatilization.Therefore, present in short supply one
Kind convenient and efficient, the bactericidal effect duration is long, has no toxic side effect, the sterilizing handset liquid without metal protection.
Summary of the invention
In order to overcome the shortcomings in the background art, the present invention disclose it is a kind of efficiently, persistently antibacterial, safe without toxic side effect,
The preparation method and its principle of sterilizing handset liquid without metal protection and application.
To achieve the goals above, the present invention is achieved through the following technical solutions.
A kind of preparation method of efficient mobile phone thimerosal, the thimerosal component is according to mass percent are as follows:
The compound alcohol is 75% ethyl alcohol and 70% isopropanol is (7-9) by volume: 1 mixing gained mixture.
The double-chain quaternary ammonium salt class compound can be N- dodecyl bi-quaternary ammonium salt, double dodecyl dimethyl chlorinations
Ammonium, alkyl methyl benzyl ammonium chloride, Dodecyl Dimethyl Amine, N- cetyl trimethylene diamine double ammonium chlorides, lauryl amine
One or more mixtures such as serial double-chain quaternary ammonium salt.
The algae extract is one or more mixtures of brown alga, red algae, green alga after culture, by ethyl alcohol
It impregnates, extraction, column chromatography for separation obtains, or extracts by aqueous solvent, and extraction, column chromatography for separation obtains.
The brown alga includes Leathesia nana, sour algae, sargassum.The red algae includes drake feather algae, Rhodomela confervoides, batrachos-permum.Institute
Stating green alga includes Enteromorpha, chlorella, U. pertusa.
The industrial essence is one of lavender, jasmine, rock rose, lemon, santal, peppermint, rose etc. or two
Kind or more mixture.
The PH regulator is the sodium hydroxide solution of citric acid or 1%.
The efficient mobile phone thimerosal, preparation method are as follows:
400g-600g algae is weighed, uses ethyl alcohol or water as solvent extraction, is repeated twice, combined extract is slightly mentioning
10 times of distilled water is added in object, is extracted with ethyl acetate after completely dissolution, by the water phase column chromatography for separation after extraction, chromatography
After obtain algae extract, it is proportionally added into material-compound tank with compound alcohol, double-chain quaternary ammonium salt class compound and glycerol, is spent
Ionized water completion, is thoroughly mixed, and industrial essence is added after it is completely dissolved, and after testing pH value, is adjusted with PH regulator
PH is 6.5-7.0 or so, filling after quarantine is qualified to seal up for safekeeping.
In the algae extraction process, use ethyl alcohol as when solvent extraction, the concentration of ethyl alcohol is 50%-60%, water-bath
Temperature be 40 DEG C -60 DEG C, time of water-bath is 30min-60min, solid-liquid ratio 1g:35-40ml；Use water as solvent extraction
When, temperature is 40 DEG C -60 DEG C, time 60min-90min, solid-liquid ratio 1g:70-75ml.
Compared with other similar products, the present invention is had the advantage that are as follows:
The mixed alcohol that 75% ethyl alcohol and 70% isopropanol mix makes protein coagulating exterminating bacterium in original ethyl alcohol
On the basis of, its permeability is increased, enhances the lethality to bacterium and mould, while not influencing the bright and clean of mobile phone surface
Degree, to original parts such as internal circuit boards also without corrosiveness.Volatilization is fast, has no toxic side effect.
Double-chain quaternary ammonium salt belongs to cationic surfactant, reachable to the killing rate of Escherichia coli, staphylococcus aureus
100%, being melted into ethyl alcohol can be enhanced its bactericidal effect, and permeability of cell membranes can be changed, compounded with compound alcohol to improve it and kill
Bacterium effect and sterilization speed.
Algae extract is containing there are many antimicrobial component, Nantural non-toxic side effects, to staphylococcus aureus, Escherichia coli etc.
With stronger inhibitory activity, in addition it is more taller than corresponding antibiotic.The polyphenols of algae secretion has microorganism
Resistance of wide spectrum (inhibition including filamentous fungi, saccharomycete, bacterium, virus etc.), and active material therein can be with skin egg
White formation moisture retention gel is further reduced the stimulation caused by skin during smearing disinfectant.There are raw material sources simultaneously
Extensively, the cheap distinguishing features such as easy to produce.
Glycerol can be reduced mixed alcohol and be injured to the degreasing of skin with the skin of effective protection people.
Industrial essence can avoid damage to mobile phone with effective protection mobile phone surface, keep mobile phone smell faint scent.
This disinfectant is more directed to electronic equipment compared with other disinfectants, focuses on metal protection and stability, reduction pair
The corrosion and damage of interior of mobile phone micro parts, the disinfectant stock solution are corrosion-free to stainless steel, carbon steel, to copper no corrosion,
There is mild corrosion to aluminium.
Efficient mobile phone thimerosal of the present invention can kill Escherichia coli, staphylococcus aureus, bud in 1 minute
The contagious pathogenics bacterium such as spore bacillus and saccharomytes.With it is efficient, easy to use, have no toxic side effect, without metal protection,
The remarkable advantages such as wide sterilization spectrum, length of antibacterial time.
