Description

Multifunctional ink compound and preparation method thereof

The invention relates to an ink compound for forming a multifunctional thin film and a preparation method thereof, in particular to an ink compound capable of forming a multifunctional thin film having antiglare effect, antibacterial effect, hydrophobic effect and self-cleaning effect.

As a modern person, daily life has long been inseparable from touch devices, ranging from small smartphones for personal use to large multimedia kiosks set up in public places, and devices that use touch screens as human-machine control interfaces It can be said to be ubiquitous, and it also brings great convenience to modern life. Users can physically touch the touch surface of the touch panel and cooperate with predefined specific gestures to input control commands to the touch device through the touch screen. The touch screen receives output information or feedback from the device.

Under such circumstances, the touch surface on the touch panel must be used as an information display surface and a touch receiving surface for receiving touch gestures at the same time, so it must meet multiple requirements. For example, when making In the case of the display surface, in order to improve the display quality and clarity, the touch surface must have the function of anti-glare (anti-glare) and have hydrophobicity (hydrophobicity). When the user frequently uses the touch panel for operations, It will cause a large number of bacteria to grow on the touch surface, especially for multimedia business machines set in public places, the touch surface is more microorganisms or microbes. It is a hotbed for the growth and spread of bacteria, and the touch surface should also have antibacterial function. The aforementioned hydrophobicity also helps to keep the surface dry to avoid bacterial growth, and to avoid moisture, hand dirt, dirt, oil stains, fatty acids, and amino groups. Acid and odorous substances remain on the touch surface, making the surface basically self-cleaning.

Therefore, in the conventional technology, antibacterial or hydrophobic materials have begun to be applied to the touch surface, or coated with multi-layer functional coatings on the touch surface, such as coating anti-glare ink, hydrophobic ink and antibacterial ink, so as to give touch However, these commonly used functional inks or coatings usually only have a single function. At present, there is no composite functional ink that can combine the functions of anti-glare, hydrophobic and antibacterial at the same time in the conventional technology. The problem is that the traditional antibacterial coating is usually a layer of smooth mirror surface with high light reflection, which is easy to reflect light and produce glare after being irradiated by light, which hinders the user's viewing, and is easy to stick to touch fingerprints, oil stains and various traces. As a result, the entire touch surface is prone to a dirty feeling.

Therefore, there are also proposals for directly synthesizing silver nanoparticles with antibacterial effects into anti-glare solutions, but there are still many problems in this technology. For example, the synthesis process needs to add alkaline substances as catalysts to accelerate the hydrolysis reaction, but the alkaline process will affect the stability of the anti-glare solution, so the silver solution needs to go through the centrifugal purification process several times, and then add it to In the anti-glare solution, and the nano-silver solution will also agglomerate due to the removal of the dispersant during the purification process; or, if you want to directly synthesize the nano-silver particles in the anti-glare solution, it is necessary to synthesize the nano-silver particles. At least 180°C high temperature reaction, high temperature will cause excessive reaction of the anti-glare solution to form a colloid, which is not conducive to subsequent processing and utilization, and the synthetic particle size of nano-silver is difficult to control at high temperature, and nano-silver is also easy to oxidize.

As a result, in view of the shortcomings existing in the conventional technology, the inventor has painstakingly Trials and research, and a persistent spirit, finally conceived the case "multifunctional ink compound and its preparation method", which can overcome the above-mentioned shortcomings.

Metal particles, especially nano-silver particles, are afraid of alkali. Nano-silver particles are not well dispersed in an alkaline environment, and they are easy to aggregate and agglomerate, and oxidize and turn black. Significantly affect the antibacterial effect.

It is worth noting that the -Si-O-Si-O- three-dimensional SiO ₂ network polymer molecular structure disclosed in Figure 2A and Figure 2B is not a spherical polymer molecular structure.

Then, the reduced polymerization solution is continuously stirred at room temperature for at least 12 hours to 54 hours, such as but not limited to 36 hours, so that the polymerization solution further undergoes condensation reaction, including dealcohol condensation reaction (alcohol condensation) Dehydration condensation reaction (water condensation) to remove most of the water and alcohols in the polymerization solution, during the process many Si(OH) _n (OR) _4-n monomer particles continue to polymerize to form -Si-O- Si-O-three-dimensional three-dimensional network polymer structure, and multiple -Si-O-Si-O-three-dimensional three-dimensional _SiO2 network polymer structure, will cross-link each other in a liquid medium to form a sol (gel) body, nano silver Solid particles (Ag NPs) will be doped in the SiO ₂ network structure polymer sol, and will be roughly uniformly dispersed in the colloid without precipitation, and finally silicon-silver (Si-Ag) nanoparticles (Si-Ag) will be formed. -Ag NPs) SiO ₂ three-dimensional network hydrophobic structure, the synthesized SiO ₂ network hydrophobic structure can also protect nano-silver particles, as revealed in Figure 3A and Figure 3B.

Then filter water, alcohols and other impurities, and receive the sol, etc. The processing step finally obtains the final product of the multifunctional ink compound of the present invention with antibacterial, hydrophobic and antiglare properties, and the final product should preferably be stored in a low temperature environment below 25°C.

After sintering, the degree of pseudo-glass crystallization can be improved, and the hardness is close to that of glass.

The multi-functional ink compound proposed by the present invention has antibacterial effect because it carries nano-silver particles, and has high hydrophobicity and self-cleaning effect because it has hydrophobic functional groups, and because the three-dimensional nano-particle _SiO2 network is hydrophobic structure, its surface has a high surface roughness (surface roughness), which can diffuse incident light, so it has an excellent anti-glare effect, and it can be coated on the touch surface by spraying, and a higher surface roughness can also be obtained degree, better anti-glare (AG) effect is obtained, so the multi-functional ink compound prepared according to the multi-functional ink compound preparation method proposed by the present invention will have antibacterial, hydrophobic and anti-glare properties at the same time.
