Description
Technical Field
The present invention relates to a composition for silicone adhesive coating and an adhesive film comprising the same, and more particularly, to a composition for silicone adhesive coating which is excellent in toughness and can exhibit an antistatic effect, and an adhesive film comprising the same.
Background
The adhesive is one of adhesives, and is often used in the form of an adhesive tape or an adhesive label obtained by applying and curing an adhesive on a substrate, and is a representative example of articles for which an adhesive is usually used. The articles are used for various purposes, such as labels for identifying objects, for packaging luggage, or for connecting multiple objects together.
The base materials used for constituting the adhesive are of various types, and are largely classified into rubber type, acrylic type, silicone type, and the like.
Rubber-based adhesives are general-purpose base materials which have been used since a long time ago, and are inexpensive and used for general-purpose adhesive tapes and the like.
The acrylic adhesive uses polyacrylate as a substrate, and thus has superior chemical properties and the like to rubber adhesives, and thus can be applied to adhesive products having higher functionality than rubber adhesives.
The silicone adhesive contains a silicone raw rubber (gum) and a silicone resin having a high viscosity and a plurality of siloxane bonds in the main chain, and in view of this, it has various excellent characteristics, specifically, heat resistance, cold resistance, weather resistance, chemical resistance, electrical insulation, and the like.
The silicone adhesive uses the excellent characteristics as described above, is used for high-performance industrial tapes such as heat-resistant tapes, industrial masking tapes, and mica tapes having flame retardancy, and is used in a condition that can exert the characteristics even under a severe environment of use.
However, in recent years, demand for silicone adhesives has been rapidly expanding, because of expansion of the product market using touch panels mounted on smartphones or tablet terminals.
In most touch panels, a screen protective film is attached to prevent contamination or defects of an interface for use in view of direct manipulation by a human finger. Most of such an adhesive layer for a screen protective film is a silicone adhesive, which takes advantage of the characteristic of excellent wettability or reworkability of the silicone adhesive to an adherend.
The base material for the screen protective film is a plastic film, and a polyester film such as PET having transparency is often used.
However, it is generally believed that the adhesion of plastic films to adhesives is poor compared to paper substrates. It is widely believed that this is because the plastic film has a flat surface and the adhesive penetrates into the substrate to have a weaker fixing (anchor) effect than the paper having a larger concavity and convexity.
If the adhesion is poor, the following problems may occur: when wound into a roll (roll), adheres to the back surface, or adheres to an adherend, so that when peeled off after a lapse of time, the adhesive layer is transferred to the adherend.
In recent years, demand for OLED panels is increasing. To manufacture an OLED panel, a PI film is laminated on Carrier glass (Carrier glass), and after an OLED layer is formed on the PI film, an encapsulation layer is placed and the OLED panel is protected with an adhesive film. Thereafter, the OLED panel and Carrier glass (Carrier glass) are removed, but at this time, the adhesion of the OLED layer is weak, damage may be caused by removing the mucosa, and a problem may occur in that the adhesive material remains at a portion in contact with the OLED panel.
In addition, it is required that there is no change in physical properties during the process and no generation of foreign substances during the OLED laser cutting process.
There is a need to develop an adhesive film capable of satisfying the above-mentioned requirements.

Detailed Description
The present invention relates to a composition for silicone adhesive coating comprising: a solvent; a polysiloxane; a CNT dispersion; a coagulant inhibitor; a cross-linking agent; and (3) a catalyst.
Hereinafter, embodiments of the present invention are described in detail to facilitate the implementation of the present invention by those skilled in the art. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
The organic light emitting element has the advantages of high response speed, thinness, small size, low power consumption, self-luminous element, flexibility and the like. Thus, in recent years, demand for illumination and the like has increased not only for next-generation display elements and flexible displays.
The organic light emitting element is formed by sequentially depositing a transparent electrode, a hole injection layer, a hole transport layer, an organic light emitting layer, an electron transport layer, an electron injection layer, and a metal electrode on a glass substrate, and is characterized in that light emission is performed using energy released while electrons and holes supplied from both electrodes are recombined in the organic light emitting layer.
Since the organic light emitting element is degraded by external moisture and external factors such as oxygen or ultraviolet rays, a packaging (encapsulation) technique for sealing the organic light emitting element is important, and in order to be applied to various applications, the organic light emitting display device is required to be manufactured to be thin.
Also, in manufacturing the OLED panel, the laser cutting process is performed in a state where the protective film is adhered, and thus it is necessary to prevent foreign materials generated by the cutting process. In the case where the modulus is too low, foreign matter is easily generated at the time of laser cutting, and in the case where the modulus is high, the adhesive layer becomes too hard to exert the intended adhesive force.
The composition for silicone adhesive coating according to an embodiment of the present invention may be provided as an adhesive film by forming an adhesive layer by coating on one surface of a substrate film.
In order to prevent static electricity, conventional adhesive films are subjected to static electricity treatment or an antistatic layer is additionally formed between the adhesive film and the base film. However, the adhesive film according to an embodiment of the present invention forms an adhesive layer using the composition for an adhesive coating, thereby being capable of exhibiting an antistatic effect based on the adhesive layer, so that an additional electrostatic treatment is not required.
Further, the adhesive force with the OLED panel is excellent and the appropriate modulus characteristic is exhibited, so that no foreign matter is generated in the laser cutting process, and thus the defective rate can be reduced.
Specifically, a composition for silicone adhesive coating according to an embodiment of the present invention comprises: a solvent; a polysiloxane; a Carbon Nanotube (CNT) dispersion; a coagulant inhibitor; a cross-linking agent; and a catalyst, wherein the polysiloxane may be selected from the group consisting of a compound represented by the following chemical formula 1, a compound represented by the following chemical formula 2, and a mixture thereof:

Wherein,,
n, m and o are the same or different from each other and each independently is an integer of 1 to 1000;
specifically, the polysiloxane represented by the chemical formula 1 may include at least one vinyl group as a substituent. As described below, the polysiloxane can combine with Si-H in the crosslinker to form an adhesive layer.
The following have been disclosed in the prior art: the release coating composition using polysiloxane contains vinyl group and is combined with a crosslinking agent. However, none of the Si-H bonds in the crosslinking agent react with Si-H bonds still present.
Si—h remaining in the adhesive layer due to the mixing of the crosslinking agent and the lack of reaction with the polysiloxane can be said to cause the induced time-dependent change.
In other words, the adhesive film should have no change in adhesiveness under a high-temperature and high-humidity environment, but si—h bonds remaining in the adhesive layer exhibit a change in physical properties under a high-temperature and high-humidity environment, whereby a problem of deterioration in the aged property occurs.
Therefore, in the present invention, it is intended to improve the stability with time by minimizing si—h remaining in the bond between the polysiloxane and the crosslinking agent.
Specifically, the polysiloxane represented by the chemical formula 1 may include at least one vinyl group as a substituent, more preferably, may include vinyl groups as substituents at both ends, and a polysiloxane having a substituted vinyl group at a side chain.
Further, the polysiloxane of the present invention may contain a compound represented by chemical formula 2 in addition to the compound represented by chemical formula 1, so that an adhesive layer can be formed by crosslinking and bonding with a crosslinking agent.
As described above, according to the inclusion of two polysiloxanes, it is possible to provide an adhesive film exhibiting unbonded characteristics.

[ chemical formula 7]
[ chemical formula 8]
Wherein,,
p, q and r are identical or different and are each independently integers from 1 to 1000.
The crosslinking agent containing the si—h group undergoes an addition reaction with the polysiloxane containing the above vinylsilane group due to a catalyst described later, so that the two compounds can be linked together.
As described above, when the hydrogen atoms bonded to the silicon atoms in the crosslinking agent are increased, the crosslinking density in the adhesive layer is increased, and the physical properties of the adhesive layer can be improved. However, when the residual amount of the hydrogen atoms bonded to the silicon atoms in the adhesive layer increases, there is a problem that the minimum timeliness cannot be ensured.
Accordingly, in the present invention, with the use of the crosslinking agent as described above, when provided as an adhesive layer, physical properties are ensured by maintaining the crosslinking density while minimizing si—h remaining in the adhesive layer, so that minimal timeliness can be exhibited.
And, the polysiloxane has a vinyl group in addition to both terminals, so that an adhesive layer having a high crosslinking density can be formed near the surface of the substrate layer, thereby providing temporal stability at peeling to achieve unbonded characteristics.
The set retarder may be selected from the group consisting of 2-methyl-3-butyn-2-ol, 2-phenyl-3-butyn-2-ol, 3, 5-dimethyl-1-hexyn-3-ol, 1-ethynyl cyclohexanol, 1, 5-hexyne, 1, 6-heptyne, 3, 5-dimethyl-1-hexen-1-yne, 3-ethyl-3-butene-1-yne, 3-phenyl-3-butene-1-yne, 1, 3-divinyl tetramethyl disiloxane, 1,3,5, 7-tetravinyl tetramethyl cyclotetrasiloxane, 1, 3-divinyl-1, 3-diphenyl dimethyl disiloxane and methyl tris (3-methyl-1-butyn-3-oxy) silane, tributylamine, tetramethyl ethylenediamine, benzotriazole, triphenylphosphine, sulfur-containing compounds, hydroperoxides, maleic acid derivatives-1-ethynyl cyclohexanol, 3-methyl-1-pentene-3-ol, and mixtures thereof.
For the purpose of promoting the polymerization reaction, the catalyst may generally be a platinum-based catalyst, a palladium-based catalyst or a rhodium-based catalyst, preferably a platinum-based catalyst, but is not limited to the above examples, and catalyst types or contents other than the above-exemplified catalysts may be used in the range generally used in the adhesive film field.
As a method for imparting an antistatic function to the adhesive film, for example, an antistatic layer made of a cationic antistatic agent is provided on one surface of a base film, and an adhesive layer is formed on the other surface. In the prior art, the method is generally used for imparting an antistatic function to an adhesive film, and although a certain antistatic effect can be exerted, there are problems as follows: as the thickness of the adhesive layer is thicker, the antistatic effect to the adhesive surface is not exhibited due to the thickness of the adhesive layer.
Further, a method of imparting an antistatic function to an adhesive film by forming an antistatic layer between a base film and the adhesive layer has been proposed. In the proposed technique, two coating steps are required to form two coating layers on a base film, and thus there are problems that the cost required for the steps is high and the production efficiency is low.
Therefore, as described above, the adhesive film exhibiting the antistatic effect has the following problems: the antistatic effect is low or the economical efficiency is low due to the steps in the manufacturing.
The present invention is characterized in that the CNT dispersion is mixed so as to exhibit an antistatic effect.
For the silicone adhesive coating composition including the CNT dispersion, when the CNT dispersion is uniformly dispersed in the adhesive coating composition and an adhesive layer is formed on one surface of a substrate film, the adhesive layer may exhibit an antistatic effect, thereby being able to be provided as a one-liquid silicone adhesive coating composition.
The CNT is a carbon nanotube and may be selected from the group consisting of single-walled carbon nanotubes, double-walled carbon nanotubes, multi-walled carbon nanotubes, and mixtures thereof. Generally, CNTs are classified into single-walled carbon nanotubes, double-walled carbon nanotubes, and multi-walled carbon nanotubes according to the number of bonds forming the wall. It is known that the antistatic effect also shows a difference according to the number of tube walls, and that single-walled carbon nanotubes can exhibit the most excellent antistatic effect.
However, production costs are a problem due to the higher price of single-walled carbon nanotubes compared to multi-walled carbon nanotubes. Accordingly, in the present invention, a CNT dispersion that can exhibit excellent antistatic effect using multi-walled carbon nanotubes can be utilized.
The CNT dispersion includes a first CNT dispersion that is a dispersion in which CNTs having a wall number of 3 to 9 are uniformly dispersed, and a second CNT dispersion that is a dispersion in which CNTs having a wall number of less than 3 are uniformly dispersed.
The first CNT dispersion and the second CNT dispersion are mixed in the state of a dispersion solution, respectively, and the CNT dispersion is a mixture of a solvent, CNTs, and a dispersant.
The dispersant may be selected from the group consisting of surfactants, coupling agents, block copolymers, monomers, oligomers, vinyl, lactic acid, caprolactone, silicone, waxes, silanes, fluoro, ethers, alcohols, esters and mixtures thereof. Preferably, it may be selected from the group consisting of anionic surfactants (SDS, naDDBS), cationic surfactants (CTAB), nonionic surfactants TWEEN, TRITION and amphoteric surfactants Tego5 and SAZM Z-3-18, more preferably, it may be selected from the group consisting of NaDDBS, dispersed PVP, tego5, SDS and mixtures thereof.
The solvent may be selected from the group consisting of water, alcohols, cellosolves, ketones, amides, esters, ethers, aromatic hydrocarbons, and mixtures thereof.
Specifically, at least one of the first CNT dispersion and the second CNT dispersion may exist in a state of silane coupling to the polysiloxane. More specifically, the polysiloxane is chemically coupled by the interaction of the functional groups present on the surface of the CNT and the polysiloxane, so that when the polysiloxane is mixed in a state of being silane-coupled with the CNT, the dispersibility can be improved to improve the CNT-based antistatic effect when it is subsequently mixed with the composition for adhesive coating.
As the silane coupling agent, there may be used a vinylsilane coupling agent (e.g., vinyltrimethoxysilane, vinyltriethoxysilane, etc.), epoxysilane coupling agent (e.g., 2- (3, 4-epoxycyclohexyl) ethyltrimethoxysilane, 3-epoxypropoxypropylmethyldimethoxysilane, 3-glycidoxypropylmethyldimethoxysilane, 3-glycidoxypropyl trimethoxysilane, 3-glycidoxypropylmethyldiethoxysilane, 3-glycidoxypropyltrimethoxysilane, etc.), styrylsilane coupling agent (e.g., p-styryltrimethoxysilane, etc.), methacryloxysilane coupling agent (e.g., 3-methacryloxypropylmethyldimethoxysilane, 3-methacryloxypropyltrimethoxysilane, 3-methacryloxypropylmethyldiethoxysilane, 3-methacryloxypropyltriethoxysilane, etc.), acryloxysilane coupling agent (e.g., 3-acryloxypropyltrimethoxysilane, etc.), aminosilane coupling agent (e.g., N-2- (aminoethyl) -3-aminopropylmethyldimethoxysilane, N-2- (3-aminopropyl) -3-trimethoxy-propyl silane, 3-triethoxysilane, 3-aminopropyl-triethoxysilane, 1-triethoxysilane N-phenyl-3-aminopropyl trimethoxysilane, N- (vinylbenzyl) -2-aminoethyl-3-aminopropyl trimethoxysilane hydrochloride, and the like), ureido silane coupling agents (e.g., 3-ureido propyl trialkoxysilane, and the like), isocyanato silane coupling agents (e.g., 3-isocyanate-propyl triethoxysilane, and the like), isocyanurate silane coupling agents (e.g., tris (trimethoxysilylpropyl) isocyanurate, and the like), or mercapto silane coupling agents (e.g., 3-mercaptopropyl methyl dimethoxy silane, 3-mercaptopropyl trimethoxysilane, and the like).
More specifically, the first CNT dispersion includes a solvent, CNTs, and a dispersant, and the second CNT dispersion includes a solvent, CNTs, and a silane coupling agent as a dispersant.
For the composition for silicone adhesive coating of the present invention, an adhesive layer is formed by one-time coating one surface of a base film, and has 10 12 Resistance of Ω/≡or less, thereby being capable of exhibiting excellent antistatic effect.
The silicone adhesive coating composition may further include a vinyl MQ resin. The vinyl MQ resin comprises an adhesive composition, so that the elastic modulus can be improved, and the crosslinking density of the adhesive layer can be improved to improve the modulus to an appropriate level, thereby preventing the generation of foreign matters when laser cutting is performed in the manufacturing process of the OLED.
More specifically, the vinyl MQ resin is contained in the form of a mixture of an alkenyl MQ resin and a polymer, and may be contained in the form of a mixture of a vinyl MQ resin and a polysiloxane represented by the following chemical formula 9:
[ chemical formula 9]
Wherein,,
s is an integer of 1 to 1000.
The vinyl MQ resin and the compound represented by chemical formula 9 may be prepared by mixing a vinyl MQ resin with a compound represented by chemical formula 1:3 to 3:5 by weight, and mixing the materials. When the content is mixed within the above range, the dispersion of the vinyl MQ resin in the silicone adhesive coating composition is easy, and the vinyl group contained in the compound is bonded to the crosslinking agent to prevent the si—h group from remaining in the adhesive layer, whereby the stability with time can be exhibited and the mechanical properties can be improved.
The composition for a silicone adhesive coating according to an embodiment of the present invention may include 50 to 70 parts by weight of the polysiloxane represented by the chemical formula 1, 80 to 120 parts by weight of the polysiloxane represented by the chemical formula 2, 0.1 to 1 part by weight of the retarder, 1 to 10 parts by weight of the crosslinking agent represented by the chemical formula 3, 1 to 5 parts by weight of the crosslinking agent represented by the chemical formula 4, 3 to 10 parts by weight of the catalyst, 50 to 70 parts by weight of the vinyl MQ resin/polymer mixture, and 30 to 40 parts by weight of the CNT dispersion based on 100 parts by weight of the solvent. When used in combination within the above range, an adhesive layer exhibiting an antistatic effect can be produced, and also exhibits stability over time even under high-temperature and high-humidity environments, and can prevent the generation of foreign substances when laser cutting is performed in an OLED manufacturing process.
A silicone adhesive film according to another embodiment of the present invention includes a substrate film; and an adhesive layer formed on one surface of the base film, wherein the adhesive layer is formed by coating the composition for silicone adhesive coating.
For the adhesive layer, by dissolving a solvent; a polysiloxane; a main agent in which the CNT dispersion, the retarder and the crosslinking agent are uniformly dispersed; and a step of preparing a coating composition by mixing the catalyst before coating the catalyst on one surface of the substrate film and then coating the catalyst on one surface of the substrate film to form an adhesive layer, wherein the polysiloxane may be selected from the group consisting of a compound represented by the following chemical formula 1, a compound represented by the following chemical formula 2, and a mixture thereof:
[ chemical formula 1]
[ chemical formula 2]
Wherein,,
n, m and o are the same or different from each other and each independently is an integer of 1 to 1000;
R 1 to R 14 Each of which is the same or different from the other, is selected from the group consisting of hydrogen, halogen, a substituted or unsubstituted alkyl group having 1 to 30 carbon atoms, a substituted or unsubstituted alkenyl group having 2 to 30 carbon atoms, a substituted or unsubstituted alkynyl group having 2 to 24 carbon atoms, a substituted or unsubstituted heteroalkyl group having 2 to 30 carbon atoms, a substituted or unsubstituted aralkyl group having 6 to 30 carbon atoms, a substituted or unsubstituted aryl group having 5 to 30 carbon atoms, a substituted or unsubstituted heteroaryl group having 2 to 30 carbon atoms, a substituted or unsubstituted heteroarylalkyl group having 3 to 30 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 20 carbon atoms, a substituted or unsubstituted heterocycloalkyl group having 3 to 20 carbon atoms, a substituted or unsubstituted cycloalkenyl group having 3 to 20 carbon atoms, a substituted or unsubstituted heteroaralkyl group having 3 to 30 carbon atoms, and a substituted or unsubstituted heteroalkenyl group having 1 to 20 carbon atoms;
The R is 1 To R 10 At least one of which is a substituted or unsubstituted alkenyl group having 2 to 30 carbon atoms.
The polysiloxane is crosslinked with a crosslinking agent, and the crosslinking is performed by a reaction of a catalyst, and when the composition for adhesive coating is prepared, the adhesive layer cannot be prepared by mixing the catalyst. Therefore, immediately before being coated on one surface of the substrate film, the catalyst is mixed with the main chain and coated on the substrate film to form an adhesive layer.
The adhesive layer of the adhesive film is characterized in that the adhesive layer is formed in a thickness of 20 to 80 mu m and has a surface resistance of 10 9 Omega/≡to 10 12 Ω/□。
As described above, in order to prevent static electricity, the conventional adhesive film performs static electricity treatment on one surface of the base film and forms an adhesive layer on the other surface. For the formation of the antistatic layer as described above, when a thinner adhesive layer having a thickness of about 3 μm is formed, an antistatic effect can be exhibited, but when an adhesive layer having a thicker thickness is formed as in the present invention, the antistatic effect is weak.
In addition, in the case of an adhesive film in which an antistatic layer is formed between a base film and an adhesive layer, there is a problem that the antistatic effect is lowered as the thickness of the adhesive layer increases, as described above, in addition to the problem that the economical efficiency is lowered due to the increase in the manufacturing process.
In contrast, with the adhesive film of the present invention, as described above, the CNT dispersion is contained in the adhesive layer, and as the CNT dispersion is uniformly distributed in the adhesive layer, an excellent antistatic effect can be exhibited. Even if a thicker adhesive layer having a thickness of 80 μm is formed, an antistatic effect by the adhesive layer itself is exhibited, and the antistatic effect can be exhibited only by the formation of the adhesive layer, so that a problem of a high manufacturing unit price can be prevented.
As a method of applying the composition for an adhesive coating to a substrate film, a known method such as a gravure roll coating method, a slit die coating method, a reverse roll coating method, an air knife coating method, or the like can be used, and as a drying method after application, a hot air drying method is mainly used. The higher the curing temperature at the time of drying, the shorter the curing time, but in view of productivity at a temperature at which the film is not deformed, it is preferable to perform curing at an appropriate temperature. Preferably, drying conditions within 1 minute to 5 minutes at a temperature of 80 ℃ to 180 ℃ are suitable.

Experimental example 1
Evaluation of antistatic Properties
Antistatic properties of examples 1 to 7, examples 13 and 14 were evaluated. Based on the ASTM D257 measurement method, measurement was performed under conditions of a Relative Humidity (RH) of 55%, a temperature of 23℃and an applied voltage of 500V.
TABLE 2
According to the experimental resultsIt was confirmed that the surface resistances of examples 1, 13 and 14 exceeded 10 12 Ω/≡without exhibiting antistatic properties. In example 1, the antistatic effect was weak because the CNT content was low, and in examples 13 and 14, the antistatic effect was weak because the CNT was not uniformly dispersed.
Also, in the case of the present invention, it was confirmed that an excellent antistatic effect was exhibited even when a thicker adhesive layer having a thickness of 80 μm was formed.
Experimental example 2
Adhesive properties of protective film
The protective film prepared according to the example was cut to a width of 1 inch, and after being attached to glass at room temperature using a roll press, was left at room temperature for 30 minutes, and then peeled off at a speed of 300mm per second at 180 °, thereby measuring adhesive force, and was left at a temperature of 85 ℃ and a humidity of 85% for 72 hours, and the change with time was confirmed by the same method as that of the adhesive force measurement.
In order to confirm whether peeling of the adhesive coating layer between films occurred, the protective film prepared according to the example was left for 72 hours at a temperature of 85 ℃ and a humidity of 85%, and it was confirmed whether peeling occurred between the adhesive layer and the film.
[ evaluation criteria ]
No peeling phenomenon occurs: o (O)
Cases where peeling occurs: x is X
TABLE 3
According to the above experimental results, in examples 1, 2 and 11, the si—h content in the crosslinker compound was low, and thus the peeling phenomenon occurred. In examples 1 and 2, the non-curability due to insufficient content of the crosslinker compound shows high temporal changes. In examples 5 and 10, the si—h content of the crosslinker compound was high, and thus high time-dependent changes were shown.
When the adhesive coating composition within the scope of the present invention was used, it was confirmed that peeling phenomenon did not occur under the conditions of high temperature and high humidity, and that minimal change with time and excellent adhesive properties were exhibited.
Experimental example 3
