Description

Anti-fouling coating module, coating system and manufacturer law

The invention relates to a coating technology, and in particular to an anti-smudge film (AS) coating module, a coating system and a manufacturing method.

With the popularity of portable electronic devices, the protection requirements for the surface of such portable electronic devices are also increasing to maintain their original appearance. At present, in order to protect the surface of these electronic devices, a film such as an anti-fouling film such as an anti-finger film is usually coated on the surface of the electronic device. For example, the touch screen surface of a currently popular touch-sensitive electronic device is usually provided with an anti-fingerprint film, so that the surface of the screen can maintain good display quality after repeated rubbing by the user. And operational sensitivity.

In general, the surface of the anti-fouling film has good anti-staining properties, prevents fingerprints from sticking, smooth touch, and is waterproof, oil-repellent and transparent. In addition, the anti-fouling film needs to have high adhesion to the surface of the device covered by it to prolong the service life of the anti-fouling film.

At present, vacuum evaporation is mostly used to form an anti-fouling film on the surface of a substrate. In this way, the anti-fouling film coating is heated under the substrate in a vacuum environment, the anti-fouling film coating is vaporized and adhered to the surface of the substrate, and the surface of the substrate is covered with a anti-fouling film. However, such a coating method can only coat a single surface of a substrate at a time, and thus is not suitable for coating a substrate having a complicated structure. In addition, in this coating method, since the anti-fouling film coating which is vaporized after being heated has a bottom-up directional property, the substrate has a shielding property to another substrate above it, so the coating method is once vapor-deposited. The substrates that can be processed are limited. On the other hand, such a heating and evaporation process requires a higher degree of vacuum, so that it takes a lot of time and cost to achieve the vacuum required to maintain the reaction. Moreover, this vapor deposition apparatus is expensive to manufacture, and the process cost is greatly increased.

There is another anti-fouling coating technology, which mainly performs surface treatment of the substrate with a normal piezoelectric slurry, and then coats the surface of the substrate with an anti-fouling coating layer, and then applies an anti-fouling coating on the substrate. The layer is heat treated to complete the coating operation of the antifouling film. This heat treatment removes excess solvent from the anti-fouling coating layer and thermally bonds the anti-fouling coating layer to bond, ripen, solidify or crystallize.

Although this coating technology can replace the traditional evaporation process, the productivity is increased, and the cost can be effectively reduced. However, the coating technology still needs to be combined with the hot baking process in the oven for more than 30 minutes after spraying. In addition, in order to automate production, the factory generally uses a tunnel oven with a length of about ten to several tens of meters. Therefore, such post-baking treatment will not only seriously affect the overall production. It can cause a gradual decrease in the process, and the equipment occupies a large area and consumes a lot of energy.

Thereby, the anti-fouling film coating mist or gas molecules can use the energy of the surface of the substrate to react with the anchor or active functional groups on the substrate to smoothly grow the anti-fouling film. Therefore, the application of the embodiment of the present invention can omit the post-baking step after the anti-fouling film coating is deposited on the surface of the substrate, and can save the post-baking equipment, thereby reducing the space occupied by the device, saving energy, and reducing the processing time. In turn, it can reduce process costs and increase production capacity.

Please refer to FIG. 1 , which is a schematic diagram of an apparatus for coating a membrane module according to an embodiment of the present invention. In the present embodiment, the anti-fouling film coating module 100 can be applied to form an anti-fouling film on the surface 104 of the substrate 102. In some examples, the coating module 100 primarily includes at least one atmospheric plasma device 106 and at least one spray element 108. As shown in FIG. 1, the coating module 100 includes an atmospheric plasma device 106 and a spray element 108 corresponding to the atmospheric plasma device 106. In other exemplary embodiments, the coating module 100 includes a plurality of atmospheric plasma devices 106, and a plurality of spray elements 108 corresponding to the atmospheric plasma devices 106, respectively. In the coating operation of the substrate 102, the atmospheric plasma device 106 is disposed at the front end of the corresponding spray element 108 to treat the substrate 102 prior to the spray element 108.

The atmospheric plasma device 106 can be adapted to pre-treat the surface 104 of the substrate 102 by surface treatment of the surface 104 of the substrate 102 to be coated with a plasma prior to coating. Atmospheric plasma device The plasma pretreatment performed by 106 removes traces of oil or dirt from the surface 104 of the substrate 102. In addition, the plasma pretreatment performed by the atmospheric plasma device 106 can provide surface 104 energy, such as thermal energy and/or potential energy, of the substrate 102. Moreover, the plasma pretreatment performed by the atmospheric plasma device 106 can surface modify the surface 104 of the substrate 102 to activate the surface 104, thereby forming a plurality of voids on the surface 104 of the substrate 102. A bond, or a reactive functional group, such as a hydroxyl group (-OH). In some exemplary examples, the atmospheric plasma device 106 includes an array jet plasma source, a rotary jet plasma source, a dielectric barrier discharge (DBD) plasma source, or a high frequency (RF) plasma source. .

The spray element 108 is disposed behind the atmospheric plasma device 106 and can be used to atomize the anti-fouling film coating solution into a plurality of anti-fouling film coating mists or to vaporize into a plurality of anti-fouling film coating gas molecules. These anti-fouling film coating mist or anti-fouling coating gas molecules can fall toward the surface 104 of the substrate 102 and deposit on the surface 104 of the plasma-treated substrate 102. In some exemplary embodiments, the antifouling coating material may comprise a fluorocarbon hydrocarbon compound, a perfluorocarbon hydrocarbon compound, a fluorocarbon hydride hydrocarbon compound, a perfluoro decane hydrocarbon compound, or a perfluoro decane hydrocarbon ether. Compound.

In the present embodiment, the distance 114 between the spout 110 of the atmospheric plasma device 106 and the spout 112 of the spray element 108 is less than 20 cm. By setting the atmospheric plasma device 106 of the coating module 100 adjacent to the spray element 108, and designing the distance 114 between the nozzle 110 of the atmospheric plasma device 106 and the nozzle 112 of the spray element 108 to be less than 20 cm, The anti-fouling film coating mist or anti-fouling coating gas molecules are deposited on the substrate 102 On the surface 104, sufficient energy is retained on the surface 104 of the substrate 102 such that the anti-fouling film coating mist or anti-fouling coating gas molecules deposited on the surface 104 of the substrate 102 can be retained on the substrate 102. The energy on the surface 104 reacts rapidly with the vacant bonds on the surface 104 to form a bond or react with the reactive functional groups on the surface 104 to form a stain-resistant finish on the surface 104 of the substrate 102. membrane.

For example, when the substrate 102 is glass, the surface of the glass generally contains a water film and contaminants adsorbed on the water film, such as organic contaminants. When the surface of the glass is pretreated by the atmospheric plasma device 106, not only the organic pollutants on the surface of the glass can be removed, but the excess energy of the plasma also removes the water film adsorbed on the surface of the glass, leaving the glass.

In some specific examples, the sterol bond on the surface of the glass is even removed when the plasma energy is high enough.

Since the clean glass will quickly form a water film in the air, when the glass containing the water film on the surface is to be subjected to the coating process of the anti-fouling film, it is necessary to first bond the molecules of the anti-fouling paint to the glass. The water film between the molecules of the antifouling coating and the glass is removed. Therefore, the prior art requires that the glass coated with the anti-fouling coating material be baked in the oven to enable the anti-fouling coating molecules to bond smoothly on the glass surface. In this embodiment, the distance 114 between the nozzle 110 of the atmospheric plasma device 106 of the coating module 100 and the nozzle 112 of the spray element 108 is controlled, so that the substrate such as glass can be pre-treated by the plasma, and the glass is adsorbed before the water film. And before the energy provided by the plasma to the glass surface remains, even if the antifouling coating molecules are in contact with the glass surface. Designed with antifouling coating molecules With the glass, the energy remaining on the surface of the glass can be utilized to rapidly form a bond at room temperature to form a bond, thereby smoothly plating a layer of anti-fouling film on the surface of the glass.

Moreover, the difficulty in moving the nozzle 110 of the atmospheric plasma device 106 and the spray element 108 can be reduced. Of course, in other examples, the coating module 100 may not have a carrier fixture that incorporates the atmospheric plasma device 106 and the spray element 108, and the atmospheric plasma device 106 and the spray element 108 are disposed separately from one another.

In some examples, as shown in FIG. 1, the coating module 100 can include only an atmospheric plasma device 106 and a spray element 108.

As shown in FIG. 2, the coating module 206 includes an atmospheric plasma device 210, and a spray element 212 corresponding to the atmospheric plasma device 210. In other exemplary embodiments, the coating module 206 includes a plurality of atmospheric plasma devices 210, and a plurality of spray elements 212 corresponding to the atmospheric plasma devices 210, respectively. In such an exemplary embodiment, the atmospheric plasma devices 210 and spray elements 212 can extend or align in a lateral direction of the substrate 202 that is perpendicular to the direction of movement 232 of the transfer system 208. Thereby, the coating system 200 can simultaneously perform a coating operation on a lateral extent in the surface 204 of the substrate 202.

In the example where the coating system 200 includes a plurality of coating modules 206, each coating module 206 can include only one atmospheric plasma device 210 and one spray element 212. In the coating operation of the substrate 202, the atmospheric plasma device 210 is disposed upstream of the corresponding spray element 212 to process the substrate 202 prior to the spray element 212.

The atmospheric plasma device 210 can be used to pre-treat the surface 204 of the substrate 202 by using a plasma to surface-treat the surface 204 of the substrate 202 to be coated prior to coating. The plasma pretreatment performed by the atmospheric plasma device 210 not only removes traces of oil or dirt on the surface 204 of the substrate 202, but also provides surface 204 energy, such as thermal energy and/or potential energy, of the substrate 202. Moreover, the plasma pretreatment performed by the atmospheric plasma device 210 can surface modify the surface 204 of the substrate 202 to activate the surface 204, thereby forming a plurality of voids on the surface 204 of the substrate 202.

In the present embodiment, the distance 218 between the spout 214 of the atmospheric plasma device 210 and the spout 216 of the spray element 212 is less than 20 cm. By setting the distance 218 between the nozzle 214 of the atmospheric plasma device 210 and the nozzle 216 of the spray element 212 to less than 20 cm, anti-fouling film coating mist or anti-fouling coating gas molecules can be deposited on the substrate 202. On the surface 204, sufficient energy is retained on the surface 204 of the substrate 202 such that the anti-fouling film coating mist or anti-fouling coating gas molecules deposited on the surface 204 of the substrate 202 can be utilized in the substrate 202. The energy on the surface 204 rapidly condenses with the vacant bonds on the surface 204 to form a bond, or reacts with the reactive functional groups on the surface 204 to form an anti-fouling film on the surface 204 of the substrate 202. . Thus, coating system 200 does not include any bake means disposed downstream of spray element 212 to bake antifouling coating mist or antifouling coating gas molecules on surface 204 of substrate 202. Therefore, when the anti-fouling film is formed by using the coating system 200, after the anti-fouling paint mist or anti-fouling coating gas molecules are formed on the surface 204 of the substrate 202 on the spray element 212, the surface 204 of the substrate 202 can be formed.

Next, in step 306, the antifouling film coating mist or antifouling coating gas molecules deposited on the surface 204 of the substrate 202 are provided to the surface 204 of the substrate 202 by plasma pretreatment and remain on the surface 204. The energy is bonded to the dangling bonds or reactive functional groups on the surface 204 such that a soil resistant film can be formed smoothly on the surface 204 of the substrate 202.

The anti-fouling film coating mist can be controlled by controlling the plasma pretreatment with the atomization of the anti-fouling film coating solution into the anti-fouling coating material mist or vaporizing into the anti-fouling coating coating gas molecules at a time interval of less than or equal to 30 seconds. When the anti-fouling coating gas molecules are deposited on the surface 204 of the substrate 202, sufficient energy is retained on the surface 204 of the substrate 202 to render the anti-fouling coating deposited on the surface 204 of the substrate 202 fog or resistant. The fouling coating gas molecules can utilize the energy remaining on the surface 204 of the substrate 202 to rapidly undergo a condensation reaction with the vacant bonds on the surface 204 to form a bond or react with the reactive functional groups on the surface 204 to further bond An anti-fouling film is formed smoothly on the surface 204 of the substrate 202. Therefore, when the anti-fouling film is formed by the method of the present embodiment, after the anti-fouling film coating mist or the anti-fouling film coating gas molecules are formed on the surface 204 of the substrate 202 on the surface of the substrate 202, the surface of the substrate 202 can be formed. The anti-fouling film is formed on the 204, and directly enters the next process for bonding or screen printing, and the baking agent of the anti-fouling film coating on the substrate 202 is not required to be baked. Baked.

According to the above embodiments, one of the advantages of the present invention is that the coating module, the coating system and the manufacturing method of the anti-fouling film of the present invention firstly perform plasma pretreatment on the surface of the substrate to provide surface energy of the substrate. Forming a dangling bond or a reactive functional group on the surface of the substrate, and then forming an anti-fouling film coating A mist or gas molecule is deposited on the surface of the substrate. Therefore, the anti-fouling film coating mist or gas molecules can bond with the dangling bonds or active functional groups on the surface of the substrate while maintaining sufficient energy on the surface of the substrate, and the anti-fouling film is smoothly formed on the surface of the substrate. Therefore, the post-baking step after the anti-fouling film coating is deposited on the surface of the substrate can be omitted.

It can be seen from the above embodiments that another advantage of the present invention is that the method for manufacturing the anti-fouling film of the present invention can omit the post-baking step after the anti-fouling film coating is deposited on the surface of the substrate, thereby reducing the space occupied by the device. Save energy and reduce process time, which in turn can reduce process costs and increase production capacity.
