Description

Composition for silicone adhesive coating and adhesive film comprising the same

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 having excellent toughness and exhibiting an antistatic effect, and an adhesive film comprising the same.

An adhesive is a type of adhesive, and is often used in the form of an adhesive tape or an adhesive label obtained by coating and curing the adhesive on a base material, and is a typical example of products using adhesives that we see on a daily basis. These articles are used for various purposes, such as being used for labels for identifying objects, for packing luggage, or for linking a plurality of things together.

There are several types of base materials for constituting the pressure-sensitive adhesive, and they are largely classified into rubber-based, acrylic-based, and silicone-based materials.

Rubber-based adhesives are general-purpose base materials that have been used for a long time, and are inexpensive and used for products such as general-purpose tapes.

Acrylic-based adhesives use polyacrylate as a base, and can be applied to adhesive products with higher functionality than rubber-based adhesives in that their chemical properties and the like are superior to those of rubber-based adhesives.

Silicone-based adhesives contain high-viscosity silicone crude rubber (gum) and silicone resin, and have many excellent characteristics in that the main chain has a large number of siloxane bonds, specifically, heat resistance, cold resistance, weather resistance, chemical resistance, electrical insulation, etc. can be heard

The silicone adhesive is used for high-performance industrial tapes such as heat-resistant tapes, masking tapes for processes, and mica tapes with flame retardancy, taking advantage of the excellent properties described above, and in cases where the properties can be exhibited even under severe environments It is being used.

However, in recent years, the demand for silicone adhesives has been rapidly expanding, and the reason for this is the expansion of the market for products employing touch panels mounted on smartphones or tablet terminals.

In most cases, the touch panel is used by attaching a screen protection film to prevent contamination or scratches of the display in that the touch panel is directly operated by a person's finger. Most of the silicone adhesives used in the adhesive layer of this screen protection film are made using the characteristics of excellent wettability and reworkability of silicone adhesives to adherends.

The base material used for the screen protection film is a plastic film, and a polyester film having transparency such as PET is often used.

However, it is considered that the plastic film has poor adhesion to the pressure-sensitive adhesive compared to the paper substrate. It is believed that this is because the plastic film has a flat surface and has a weak anchoring effect in which the pressure-sensitive adhesive penetrates into the substrate compared to paper with large irregularities.

If the adhesiveness is poor, there may be problems such as smearing on the back side when wound with a roll or adhering to an adherend and transferring the adhesive layer to the adherend when peeling after time passes.

Recently, demand for OLED panels is increasing. In order to manufacture an OLED panel, a PI film is laminated on a carrier glass, an OLED layer is formed on the PI film, an encapsulation layer is placed, and the OLED panel is protected with an adhesive film. After that, the OLED panel and the carrier glass are removed. At this time, the adhesion of the OLED layer is weak and damage may occur due to the removal of the adhesive film, and the adhesive material may remain in the portion in contact with the adhesive surface. can

In addition, it will be said that there is no change in physical properties during the process and that no foreign matter is generated during the OLED laser cutting process.

It is necessary to develop an adhesive film that can satisfy the above requirements.

Organic light emitting devices have advantages such as fast response speed, thin and small size, low power consumption, self-light emitting devices, flexibility, etc. Recently, demand for them is increasing not only for next-generation display devices and flexible displays, but also for lighting.

The organic light emitting device is formed by 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 in this order on a glass substrate, and electrons and holes supplied from both electrodes recombine in the organic light emitting layer. It is a principle that emits light using the energy emitted.

Since the organic light emitting device can be deteriorated by external factors such as external moisture and oxygen or ultraviolet rays, packaging technology for sealing the organic light emitting device is important, and to apply to various applications, the organic light emitting display device is manufactured thinly. is required to be

In addition, when manufacturing the OLED panel, the laser cutting process is performed in a state in which the protective film is adhered, and foreign matter generation by the cutting process must be prevented. The occurrence of foreign substances in the cutting process is related to the modulus of the adhesive layer. If the modulus is too low, foreign substances may occur during laser cutting, and if the modulus is high, the adhesive layer becomes excessively hard, thereby exhibiting the desired adhesive force. becomes impossible

n, m and o are the same as or different from each other, and are each independently an integer of 1 to 1000.

Specifically, the polysiloxane represented by Chemical Formula 1 may include at least one vinyl group as a substituent. As will be described later, the polysiloxane may be combined with Si—H in a crosslinking agent to form a release layer.

A composition for release coating using a conventional polysiloxane includes a vinyl group and is bonded to a crosslinking agent. However, no reaction with Si-H in the cross-linking agent occurred, and Si-H bonds remained.

Due to the mixing of the crosslinking agent and non-reaction with the polysiloxane, Si-H remaining in the release layer may be a cause of change over time.

That is, the adhesive film should have no change in releasability in a high-temperature and high-humidity environment, but Si-H bonds remaining in the adhesive layer show a change in physical properties in a high-temperature and high-humidity environment, resulting in poor aging properties.

Therefore, in the present invention, it is intended to increase the stability over time by minimizing the residual Si-H in the bond between the polysiloxane and the crosslinking agent.

Specifically, the polysiloxane represented by Formula 1 may include at least one vinyl group as a substituent, and more preferably may include a polysiloxane having vinyl groups as substituents at both ends and having vinyl groups substituted at side chains.

In addition, the polysiloxane of the present invention may further include a compound represented by Chemical Formula 2 in addition to the compound represented by Chemical Formula 1 to form an adhesive layer through crosslinking with a crosslinking agent.

As described above, by including two types of polysiloxane, it can be provided as an adhesive film exhibiting non-adhesive properties.

[Formula 8]

here,

The Si-H group-containing crosslinking agent may undergo an addition reaction with the above-described polysiloxane containing a vinyl silane group due to a catalyst to be described later, thereby linking the two compounds.

As described above, when the number of hydrogen atoms bonded to silicon atoms in the crosslinking agent increases, the crosslinking density in the adhesive layer increases, and thus the physical properties of the adhesive layer can be enhanced. When the residual increases, there is a problem that the minimum age is not secured.

Therefore, in the present invention, as the crosslinking agent is used, when provided as an adhesive layer, it is possible to maintain the crosslinking density to secure physical properties and minimize the residual Si-H in the adhesive layer to exhibit minimum aging. .

In addition, the polysiloxane further includes a vinyl group in the side chain of one end in addition to both ends, so that an adhesive layer having a high crosslinking density can be formed on the side close to the substrate layer, thereby providing stability over time during peeling, resulting in non-adhesive properties. can be implemented.

The retardant is included to prevent pre-curing or gelling before processing, and 2-methyl-3-butyn-2-ol, 2-phenyl-3-butyn-2-ol, 3,5-dimethyl-1 -Hexyn-3-ol, 1-ethynyl cyclohexanol, 1,5-hexadiyne, 1,6-heptadiyne, 3,5-dimethyl-1-hexene-1-yne, 3-ethyl-3 -buten-1-yne, 3-phenyl-3-butene-1-yne, 1,3-divinyltetramethyldisiloxane, 1,3,5,7-tetravinyltetramethylcyclotetrasiloxane, 1,3- Divinyl-1,3-diphenyldimethyldisiloxane, methyltris(3-methyl-1-butyn-3-oxy)silane, tributylamine, tetramethylethylenediamine, benzotriazole, triphenylphosphine, sulfur-containing compounds, hydroperoxy compounds, maleic acid derivatives-1-ethynylcyclohexanol, 3-methyl-1-penten-3-ol, and mixtures thereof.

For the purpose of accelerating 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 other types of catalysts in addition to the catalysts exemplified above Alternatively, all of the contents may be used within the range commonly used in the adhesive film field.

As a method of imparting an antistatic function to the adhesive film, for example, an antistatic layer made of a cationic antistatic agent is provided on one side of a base film, and an adhesive layer is formed on the other side. Conventionally, it is commonly used to impart an antistatic function to an adhesive film, and although it can exhibit a certain antistatic effect, the thicker the adhesive layer, the more antistatic effect on the adhesive surface due to the thickness of the adhesive layer. There is a problem that does not appear.

In addition, a method of imparting an antistatic function to the adhesive film by forming an antistatic layer between the base film and the adhesive layer has also been proposed. In the case of the proposed technology, since two coating layers are formed on the base film, two application steps are required, and there is a problem that the cost required for the process is high and the production efficiency is also low.

Therefore, as described above, the adhesive film exhibiting the antistatic effect has a problem in that the antistatic effect is low or the economic efficiency is low due to the manufacturing process.

The present invention is characterized in that a CNT dispersion is mixed in order to exhibit an antistatic effect.

The silicone adhesive coating composition containing the CNT dispersion can exhibit an antistatic effect by the adhesive layer when the CNT dispersion is uniformly dispersed in the adhesive coating composition to form an adhesive layer on one side of a base film, thereby providing a one-component type of adhesive coating composition. A silicone adhesive coating composition may be provided.

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. In general, CNTs are classified into single-walled carbon nanotubes, double-walled carbon nanotubes, and multi-walled carbon nanotubes according to the number of bonds constituting the wall. It is known that there is a difference in antistatic effect depending on the number of walls, and single-walled carbon nanotubes can exhibit the best antistatic effect.

However, due to the high price of single-walled carbon nanotubes compared to multi-walled carbon nanotubes, production cost may be a problem. Therefore, in the present invention, a CNT dispersion that can exhibit an excellent antistatic effect using multi-walled carbon nanotubes can be used.

The CNT dispersion includes a first CNT dispersion and a second CNT dispersion, the first CNT dispersion is a dispersion in which CNTs having 3 to 9 walls are uniformly dispersed, and the second CNT dispersion is uniformly dispersed. The CNT dispersion is a dispersion in which CNTs having a number of walls of less than 3 are uniformly dispersed.

The first CNT dispersion and the second CNT dispersion are separately mixed in a dispersed solution state, and the CNT dispersion is a mixture of a solvent, CNTs, and a dispersing agent.

The dispersant includes surfactants, coupling agents, block copolymers, monomers, oligomers, vinyls, lactics, caprolactones, silicones, waxes, silanes, fluorines, ethers, alcohols, esters and It may be selected from the group consisting of mixtures thereof. Preferably, anionic surfactants such as SDS and NaDDBS, cationic surfactants CTAB, nonionic TWEEN, TRITION, and amphoteric surfactants Tego5 and SAZM Z-3-18 may be selected, more preferably NaDDBS , dispersed PVP, Tego5, SDS, and mixtures thereof.

The solvent may be selected from the group consisting of water, alcohol, cellusolve, ketone, amide, ester, ether, aromatic, hydrocarbon, and mixtures thereof.

Specifically, at least one of the first CNT dispersion and the second CNT dispersion may exist in a silane-coupled state to the polysiloxane. More specifically, the polysiloxane is chemically coupled by a mutual reaction between a functional group present on the surface of the CNT and the polysiloxane. It is possible to increase the antistatic effect by CNT.

The silicone adhesive coating composition of the present invention forms an adhesive layer on one surface of a base film by coating once, and the adhesive layer has a resistance of 10 ¹² Ω/ㅁ or less, thereby exhibiting an excellent antistatic effect.

The silicone adhesive coating composition may further include a vinyl MQ resin. The vinyl MQ resin is included in the pressure-sensitive adhesive composition to increase the elastic modulus and increase the crosslinking density of the pressure-sensitive adhesive layer to increase the modulus to an appropriate level, thereby preventing foreign matter from being generated during laser cutting in the OLED manufacturing process.

The vinyl MQ resin is more specifically included in the form of a mixture of vinyl MQ resin and a polymer, and may be included as a mixture of vinyl MQ resin and polysiloxane represented by Formula 9 below:

[Formula 9]

here,

s is an integer from 1 to 1000.

The vinyl MQ resin and the compound represented by Formula 9 may be mixed in a weight ratio of 1:3 to 3:5. When mixed and included within the above range, the vinyl MQ resin is easily dispersed in the silicone adhesive coating composition, and due to the vinyl group included in the compound, it is combined with the crosslinking agent to prevent the Si—H group from remaining in the adhesive layer, It shows stability over time and can improve mechanical properties.

The silicone adhesive coating composition according to an embodiment of the present invention contains 50 to 70 parts by weight of polysiloxane represented by Formula 1, 80 to 120 parts by weight of polysiloxane represented by Formula 2, and 0.1 part by weight of a retardant, based on 100 parts by weight of a solvent. to 1 part by weight, 1 to 10 parts by weight of the crosslinking agent represented by Formula 3, 1 to 5 parts by weight of the crosslinking agent represented by Formula 4, 3 to 10 parts by weight of catalyst, 50 to 70 parts by weight of vinyl MQ resin/polymer mixture, and It may be included in 30 to 40 parts by weight of the CNT dispersion. When mixed and used within the above range, it can be produced as an adhesive layer that exhibits an antistatic effect, exhibits stability over time even in a high temperature and high humidity environment, and can prevent foreign matter from being generated during laser cutting in the OLED manufacturing process.

The adhesive layer may include a solvent, polysiloxane; a CNT dispersion, a retardant and a crosslinking agent are uniformly dispersed; and a catalyst are mixed on one side of a base film before coating to prepare a coating composition, and then applied to one side of the base film to form an adhesive layer. The polysiloxane is a compound represented by Formula 1 below or a compound represented by Formula 2 below. and mixtures thereof:

[Formula 1]

[Formula 2]

here,

n, m and o are the same as or different from each other, and each independently represents an integer from 1 to 1000;

R ₁ to R ₁₄ are the same as or different from each other, and are each independently 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, or a substituted or unsubstituted carbon atom having 2 to 24 carbon atoms. Alkynyl group, substituted or unsubstituted heteroalkyl group having 2 to 30 carbon atoms, substituted or unsubstituted aralkyl group having 6 to 30 carbon atoms, substituted or unsubstituted aryl group having 5 to 30 carbon atoms, substituted or unsubstituted heteroalkyl group having 2 to 30 carbon atoms Aryl group, substituted or unsubstituted unsubstituted heteroarylalkyl group having 3 to 30 carbon atoms, substituted or unsubstituted cycloalkyl group having 3 to 20 carbon atoms, substituted or unsubstituted heterocycloalkyl group having 3 to 20 carbon atoms, substituted or unsubstituted heterocycloalkyl group having 3 to 20 carbon atoms It is selected from the group consisting of 20 cycloalkenyl groups, substituted or unsubstituted heteroaralkyl groups having 3 to 30 carbon atoms, and substituted or unsubstituted heteroalkenyl groups having 1 to 20 carbon atoms,

At least one of R ₁ to R ₁₀ is a substituted or unsubstituted alkenyl group having 2 to 30 carbon atoms.

The polysiloxane undergoes cross-linking with a cross-linking agent. The cross-linking reaction proceeds by a catalyst, and when the catalyst is mixed during preparation of the adhesive coating composition, it becomes impossible to manufacture the adhesive layer. Accordingly, the catalyst is mixed with the main chain immediately before application on one surface of the base film and applied to the base film to form an adhesive layer.

The adhesive layer of the adhesive film forms an adhesive layer with a thickness of 20 to 80 μm, and has a surface resistance of 10 ⁹ to 10 ¹² Ω/ㅁ.

As described above, in the conventional adhesive film, one surface of the base film is charged, and an adhesive layer is formed on the other surface to prevent static electricity. Formation of the antistatic layer as described above may exhibit an antistatic effect when the thickness of the adhesive layer is formed as thin as about 3 μm, but when the thickness of the adhesive layer is formed thick as in the present invention, the antistatic effect is insignificant.

In addition, even in the case of an adhesive film in which an antistatic layer is formed between the base film and the adhesive layer, as described above, economical efficiency is reduced due to the addition of the manufacturing process, and the antistatic effect increases as the thickness of the adhesive layer increases. I have a falling problem.

On the other hand, the adhesive film of the present invention includes the CNT dispersion in the adhesive layer as described above, and since the CNT dispersion is uniformly distributed in the adhesive layer, it can exhibit excellent antistatic effect. Even if the thickness of the adhesive layer is formed as thick as 80 μm, the antistatic effect is exhibited by the adhesive layer itself, and the antistatic effect can be exhibited only by the formation of the adhesive layer, thereby preventing an increase in manufacturing cost.

As a method of applying the adhesive coating composition to the base film, known methods such as a gravure roll coating method, a slot die coating method, a reverse roll coating method, and an air knife coating method may be employed. As a drying method after coating, hot air is mainly used. A drying method is used. The higher the curing temperature during drying, the shorter the curing time. Preferably, drying conditions within 1 to 5 minutes under a temperature of 80 to 180 ° C are suitable.
