Description
Technical field
The present invention relates to computer accessories fields, and in particular to a kind of manufacture craft of antibacterial Keyboard.
Background technique
After 21 century enters the information age, computer industry flourishes, and computer application is in worldwide
It is interior more and more common.With the raising of living standards of the people and the development of science and technology, the quantity of computer personal user is continuous
Soaring, application level is continuously improved, and especially the fields such as internet, communication, multimedia achieve marvelous achievement in application.
Keyboard is a part indispensable in computer use process.The long-time of keyboard uses, usually by dirts such as sweat stains on finger
Surface of keyboard is contaminated, so that surface of keyboard bacterium easy to breed.If surface of keyboard has bred pathogenic bacteria, and connects with human body
Touching is very easy to cause the infection of disease, generates threat to the health of human body.
Silver is combined with the intracorporal oxidative metabolism enzyme (- SH) of thallus, and thallus is made to be choked to death.Tool report, what nano silver generated
Powerful bactericidal effect can kill 650 various bacterias, broad-spectrum sterilization and not any drug resistance in several minutes.
1884, German obstetrician for the first time instilled silver nitrate solution in newborn's eye, blindness caused by prevention neonatal ophthalmia,
The incidence for making newborn blind is reduced to 0.2% from 10%.
Common antibacterial Keyboard is one layer of antibiotic layer to be arranged in surface of keyboard, but antibiotic layer not only will affect the hand of keyboard
Sense and appearance, and common antibiotic layer is to add antibacterial agent wherein, and antibacterial agent is easy failure over time, causes
The anti-microbial property of keyboard fails.
Summary of the invention
The purpose of the present invention is to provide a kind of manufacture crafts of antibacterial Keyboard.Its object is to solve surface of keyboard to be difficult to
The problem of long acting antibiotic, the process are simple, practical.
In order to achieve the above objectives, base case of the invention are as follows: following alleged " number " is " mass fraction ".
1, the keyboard case and key of ABS material are thoroughly cleaned with deionized water and ethyl alcohol.
2, the keyboard case of ABS material and key are put into 10% hydrogen peroxide and impregnated 15~30 minutes, then by it
After taking-up is cleaned up with deionized water, drying for standby.
3,1 parts of ethyl orthosilicates, 0.2 part of silver nitrate are added in 2 parts of dehydrated alcohols, and it is molten to obtain colorless and transparent silica
Glue, and continue stirring 2 hours.
4, by hydrogen peroxide treated keyboard case and keytop even application layer of silicon dioxide colloidal sol, to its surface
It after drying, is rinsed with deionized water, is then air-dried.It is rinsed again with dehydrated alcohol after dry tack free.Repeat the mistake
Journey 3 times.
5, it is then 12 hours dry in 40 DEG C of 1000Pa or less.
The working principle and advantage of this programme are: being surface-treated by hydrogen peroxide to ABS material keyboard, by its table
Face aoxidizes to obtain the surface layer by hydroxyl modified, sol-gal process is then used, by the silicon dioxide gel layer containing silver nitrate
It is deposited on surface of keyboard.By the bacterium of the superpower bactericidal property killing surface of keyboard of silver ion in silver nitrate, and relative to
Conventional nano silver is compared, and the agglomeration traits of nano silver are difficult to solve, this significantly limits the use of nano silver.Due to dioxy
SiClx colloidal sol and surface of keyboard are chemisorption, therefore its adsorption capacity is very strong.Silica hardness is high, high abrasion resistance.
Preferred embodiment one: as the preferred embodiment of basic scheme, the step 1 by ultrasonic wave assist deionized water and
Ethyl alcohol cleaning, can be improved the cleaning speed of keyboard, faster and better removing keyboard and keytop spot, improve work effect
Rate.
Preferred embodiment two: preferably one preferred embodiment: the step 2, the soaking time of hydrogen peroxide are 20
Minute, inventor has found the product good anti-bacterial effect obtained using above-mentioned parameter through a large number of experiments.
Preferred embodiment three: preferably two preferred embodiment: the step 3, after silicon dioxide gel configuration,
It is stirred under the conditions of 35~45 DEG C, inventor has found that obtain silicon dioxide gel uniform using above-mentioned condition through a large number of experiments
Degree is preferable.
Preferred embodiment four: preferably three preferred embodiment: the step 3, after silicon dioxide gel configuration,
It is persistently stirred under the conditions of 40 DEG C, inventor has found that obtain silicon dioxide gel uniform using above-mentioned condition through a large number of experiments
Degree is preferable.
Preferred embodiment five: preferably four preferred embodiment: the process environments of the step 4 control air humidity
30% hereinafter, inventor has found the product good anti-bacterial effect obtained using above-mentioned condition through a large number of experiments.
