Abstract
The invention discloses a keyboard capable of preventing germ spreading. A food-grade nano-silver sol material is arranged on the surface of the keyboard. The keyboard has the advantages that germs in the keyboard can be effectively killed and prevented from spreading, fusion with the prior art is simple, and cost is low.
Description
Technical field
The present invention relates to a kind of environmentally friendly keyboard, the keyboard that more specifically a kind of bacteriological protection is propagated.
Background technology
Keyboard is the great articles for daily use of people's usage amount, and the health of keyboard is also to be closely related with the health of people,
The routine use of current keyboard（The especially public place such as Internet bar, hotel）In often all do not carry out high-temperature disinfection treatment, such as
What strengthens the research direction that the antibiotic property of keyboard becomes in industry.
In recent years, self assembly and the load synthetic technology of nanoparticle are carried out for main body by the surfaces externally and internally of porous material
The study hotspot of field of nanometer material technology is become, silver type antibacterial agent has at aspects such as security, persistence, antibiotic property, heat resistances
There is the performance more more excellent than organic antibacterial agent, so, this kind of material is just being applied in the middle of the 19th century life and medicine
Aspect.Foreign countries have assembling preparation of numerous scholars to nanometer silver type antibacterial agent in different materials to conduct in-depth research, and are
Japan's research in this respect is achieved than larger progress, and part achievement has been realized in industrialization.Today, China
The research of nanometer silver type antibacterial agent have also been obtained development energetically, and related industry also begins to flourish.
Huang Zhanjie's<<The development of inorganic antiseptic and application>>Material Leader, 1999,13（2）：35 and Feng Naiqian, Yan Jian
China<<The development and its application of silver type inorganic antiseptic>>Material Leader, 1998,12（2）：Nano silver antimicrobials are described in 1
Sterilization mechanism：
One is after silver ion and bacterium haptoreaction in the haptoreaction of silver ion, i.e. antibacterial product, to cause microorganism intrinsic
Component damage produces dysfunction.When micro silver ion reaches microbial cell film, because the latter it is negatively charged, by storehouse
Logical sequence gravitation, makes two all firmly to adsorb, and silver ion penetration cell wall enters intracellular, and and its（-SH）Radical reaction, coagulates albumen
Gu, the activity of cell synzyme is destroyed, and cell loss division growth ability is dead.
Additionally, silver ion can also destroy microorganism electric transmission system, respiratory system and substance delivery system.And work as bacterium
After body loses activity, silver ion again can from thalline separate out, repeat fungicidal property, because a little its antibacterial effect can be held
After permanent.
Two is light-catalyzed reaction, and the trace silver of material surface distribution in the presence of light, can play catalytic active center
Effect, activates the oxygen in water and air, produces hydroxyl radical free radical（OH-）And active oxygen ion（O-2）, active oxygen ion is with very
Strong oxidability, can at short notice destroy the multiplication capacity of bacterium and make cell death, so as to reach the purpose of antibacterial.
The content of the invention
In order to solve deficiency of the prior art, the present invention proposes a solution, and concrete technical scheme is as follows：One
Plant the keyboard that bacteriological protection is propagated, it is characterised in that surface of keyboard is provided with the nano silver colloidal sol material of food-grade.
Keyboard according to claim 1, it is characterised in that the average grain diameter of silver is at 2 nanometers in nano silver colloidal sol.
3 keyboards according to claim 2, it is characterised in that nano silver colloidal sol is made of using following steps：Step
One, the requirement of silver nitrate and water by silver content in solution for 20-10000pm is mixed, table is added in silver nitrate solution
Face activating agent, is obtained after mixed solution and stirs 10-30 minutes；
Step 2, the mixed solution that step one is obtained carries out slaking reaction, and concrete mode is irradiated with light with violet rays source
The small particle nano silver colloidal sol that particle diameter is 1-5 nanometers is obtained after 30 minutes to 24 hours.
The Advantageous Effects that the present invention reaches are：The bacterium effectively killed in keyboard simultaneously prevents it from propagating, and with it is existing
The fusion of technology is simple, and cost is relatively low.
Description of the drawings
Fig. 1 is the TEM figures of the nano silver colloidal sol that the present invention is prepared.
Specific embodiment
Embodiment 1
The preparation of nano silver colloidal sol：Step one, the requirement of silver nitrate and water by silver content in solution for 20-10000pm is carried out
Mixing, adds surfactant in silver nitrate solution, is obtained after mixed solution and stirs 10-30 minutes；
Step 2, the mixed solution that step one is obtained carries out slaking reaction, and concrete mode is irradiated with light with violet rays source
The small particle nano silver colloidal sol that particle diameter is 1-5 nanometers is obtained after 30 minutes to 24 hours.
Obtained nano silver colloidal sol is coated on into existing surface of keyboard by the way of spraying.
Embodiment 2
The preparation of nano silver colloidal sol：Step one, the requirement of silver nitrate and water by silver content in solution for 20-10000pm is carried out
Mixing, adds surfactant in silver nitrate solution, is obtained after mixed solution and stirs 10-30 minutes；
Step 2, the mixed solution that step one is obtained carries out slaking reaction, and concrete mode is irradiated with light with violet rays source
The small particle nano silver colloidal sol that particle diameter is 1-5 nanometers, the TEM of obtained nano silver colloidal sol are obtained after 30 minutes to 24 hours
As a result as shown in figure 1, the particle diameter of Nano Silver is in 2 rans.
Obtained nano silver colloidal sol is coated on into existing surface of keyboard by the way of brushing.
