Abstract
The present invention relates to a kind of preparation method of nano silver/quaternary ammonium salt compound disinfectant, preparation method is as follows：Nano silver is distributed in deionized water, ultrasound 30 minutes, then quaternary ammonium salt is added, surfactant and other auxiliary agents are then added in stirring 10 minutes, continue stirring 20 minutes, alcohol is added while stirring, it is eventually adding deionized water, continues stirring 1 hour, you can obtain the composite disinfectant of broad-spectrum sterilization, consistency of performance.The present invention has the following advantages：It is antibacterial, sterilizing ability is strong, environmentally protective, applied widely, simple process and low cost is honest and clean.
Description
Technical field
The present invention relates to a kind of preparation method of nano silver/quaternary ammonium salt compound disinfectant, more particularly to a kind of bactericidals
Ability is strong, sterilizing type is more, effect is lasting, the preparation side of simple for process, low-cost nano silver/quaternary ammonium salt compound disinfectant
Method.
Background technology
With the development of science and technology, the improvement of people's living standards, people to healthy and safe living environment more and more
Concern.And in daily life, some public places, such as public restroom, hospital, hotel are not only produced since the stream of people is larger
The bacteriums such as raw dense peculiar smell is also Escherichia coli, staphylococcus glucose coccus, sugared coccus of white grapes provide good life
Dis environment.Meanwhile some public places also become infect disease occurred frequentlyly.In public places, many communicable diseases, example
Such as meningitis, influenza, severe acute respiratory syndrome, pathogen can pass through air, droplet transmission.It can
It causes Heavy environmental pollution, disease to infect, greatly harm is generated to human health.
Currently, common sterilizing method is the chemical methodes and ultraviolet light irradiation, ozone etc. such as disinfectant sprinkling, stifling
Physical method, the medicament that chemical method uses have sharp aroma or irritate damage to skin mostly, are adsorbed on the table of object
Face distributes in air, causes secondary pollution, less serious case to cause allergic reaction or induce dermatitis environment, severe one sucks lung
Skin is corroded, is threatened to health.If lactic acid, Peracetic acid corrosivity are strong, human respiratory tract, 84 thimerosals are irritated
When air concentration is higher, has to human skin and stronger irritate damage.And the irradiation of physical method ultraviolet light is by fluorescent tube intensity, cleaning
Degree, ambient temperature and humidity, shelter and apart from influence, and the side reactions such as ultraviolet light ophthalmia can be caused.In conclusion current
Disinfectant such as has penetrating odor there is shortcomings, and sterilizing ability is weak, fungicidal spectrum is relatively narrow, secondary pollution etc..Therefore,
Research and development one kind is antibacterial, sterilizing ability is strong, nontoxic, has no irritating odor, environmentally protective disinfectant is one great and difficult
Huge task.
The appearance of nano silver/quaternary ammonium salt compound disinfectant can solve the above problems, the composite material it is with the following functions and
Feature：（1）Silver nano-grain size in prepared composite disinfectant is smaller, makes its increased activity, and this activity is extremely strong to be received
Rice Argent grain is let out by damage DNA of bacteria, interruption cell signalling, the oxidative damage of active oxygen radical, thalline content
Leakage, dehydrogenase inactivation, to play sterilization, antibacterial effect；（2）Quaternary ammonium salt in prepared composite disinfectant is water-soluble
Exist in the form of cation in liquid, has very strong affine adsorption capacity to all bacteriums and virus surface, and its group can be destroyed
Knit cell, can wide spectrum, efficiently kill bacterium, stable and durable effect.The composite disinfectant is sprayed on any substrate surface,
Such as wall, clothing, leather, glass, ceramics, metal not only have very strong sterilization, bacteriostasis, but also can remove different
Taste.
Invention content
A kind of bactericidal ability of present invention offer is strong, sterilizing type is more, effect is lasting, simple for process, low-cost
The preparation method of nano silver/quaternary ammonium salt compound disinfectant can be used for general object table and textile disinfecting, it can also be used to equipment, instrument
Disinfection.
That the present invention overcomes traditional disinfection agent sterilizing abilities is weak, fungicidal spectrum is relatively narrow, irritant smell, secondary pollution etc. are asked
Topic.
The advantages of nano silver/quaternary ammonium salt compound disinfectant of the present invention is：It is nano silver is compound with quaternary ammonium salt so that compound to disappear
