Description
Technical Field
The invention relates to a release film and a preparation method thereof.
Background
In general, a silicone-based adhesive (hereinafter, this means including a pressure-sensitive adhesive) has characteristics of heat resistance, weather resistance, flexibility, chemical resistance, and the like, and recently, IT is widely used not only for general industrial tapes but also in IT fields of mobile phones, semiconductors, displays, and the like.
However, since the silicone-based release film using the silicone-based adhesive is completely laminated on the adhesive and is not peeled off, a film coated with a release agent containing a fluorine-based resin is generally used. After curing, the release agent containing a fluorine-based resin is likely to cause interlayer curing due to the residual curing agent, and the peeling force and the residual adhesion rate are likely to decrease.
In order to solve these problems, a release film excellent in light peelability, residual adhesiveness and coating appearance and a method for preparing the same are still required.

The substrate constituting the release film, the release layer, the release film and the method for preparing the same will be described in detail below.
< substrate >
As the substrate used in the present invention, a known substrate film or substrate sheet can be used as the substrate of the release film. For example, a polyester resin film can be used as the substrate. As the polyester-based resin, a known substrate film commonly used in the field of release films can be used. For example, as the polyester-based resin base material film, polyester-based base material films disclosed in korean registered patent No. 10-1268584, korean registered patent No. 2012-45213, and korean registered patent No. 2012-99546, etc. can be used. However, in one embodiment of the present invention, in order to describe only the features of the present invention, the description of the polyester-based substrate film is not limited, but should be understood to include technical features related to the known polyester-based substrate film.
The polyester-based substrate film may include polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, or the like.
As the polyester-based resin forming the substrate film, a polyester obtained by polycondensing an aromatic dicarboxylic acid or an aliphatic dicarboxylic acid with an aliphatic diol may be used, wherein isophthalic acid, phthalic acid, terephthalic acid, 2, 6-naphthalenedicarboxylic acid, adipic acid, sebacic acid, hydroxycarboxylic acid (for example, ρ -oxybenzoic acid or 4-hydroxybenzoic acid), and the like may be used as the aromatic dicarboxylic acid or the aliphatic dicarboxylic acid, and ethylene glycol, diethylene glycol, propylene glycol, butylene glycol, 1, 4-cyclohexanedimethanol, neopentyl glycol, and the like may be used as the aliphatic diol. As such a polyester resin, two or more of a dicarboxylic acid component and a diol component may be used in combination, or a copolymer including a third component may be used.
In addition, as the polyester-based substrate film, a uniaxially or biaxially oriented film having high transparency and excellent productivity and processability can be used. As the polyester-based substrate film, polyethylene terephthalate (PET), poly (vinyl 2, 6-naphthalate) (PEN), or the like can be used.
In addition, the polyester-based substrate film may include particles to provide excellent inter-Roll (Roll) running characteristics, and may be used without limitation as long as the added particles can exhibit excellent sliding characteristics.
Examples of such particles may include particles of silica, calcium carbonate, calcium sulfate, calcium phosphate, magnesium carbonate, magnesium phosphate, barium carbonate, kaolin, alumina, titanium oxide, and the like, and the shape of the particles used is not limited, but any of, for example, spherical, block-shaped, rod-shaped, and plate-shaped particles may be used.

At this time, when the average particle diameter of the particles is less than 0.1 μm, an aggregation phenomenon between the particles may occur, resulting in poor dispersion, and when the average particle diameter of the particles is greater than 5 μm, coating defects may occur during post-processing due to deterioration of surface roughness characteristics of the thin film.
Further, when the polyester-based substrate film includes particles, the content of the particles may be 0.01 to 5 wt%, for example, 0.01 to 3 wt%, based on the total weight of the polyester-based substrate film. When the content of the particles is less than 0.01 wt%, the slip characteristics of the polyester film may be deteriorated, resulting in deterioration of walking characteristics between rolls, and when the content of the particles is more than 5 wt%, the surface smoothness of the film may be deteriorated.
The thickness of the polyester-based substrate film is not limited, but may be 30 μm to 125 μm.
When the polyester-based substrate is too thin to 30 μm or less, deformation may be caused by heat treatment during processing, and when the polyester-based substrate is too thick to 125 μm or more, problems may occur in curing due to insufficient heat transfer.

< method for producing Release film >
The preparation method of the release film according to one embodiment of the invention comprises the following steps: preparing a base material; adding and stirring inorganic particles, a fluorine-containing silane compound and an aminosilane-based co-reactant, and then heating to prepare organic-inorganic particles; and coating a composition for forming a release layer, including a polymer or copolymer including a fluorine-containing polysiloxane, and organic-inorganic particles on at least one side of the substrate and drying to form a release layer to prepare the above release film, wherein the weight ratio of the inorganic particles to the fluorine-containing silane compound may be 4: 1 to 20: 1.

In this case, the solvent used in the composition for forming a release layer may be used without limitation as long as the solid content in the composition for forming a release layer can be dispersed and coated on the substrate. When the total solid content of the composition for forming a release layer is less than 0.5 wt%, a uniform release layer cannot be formed, so that problems such as poor peeling between a silicone-based adhesive layer and a release film may occur, and when the total solid content of the composition for forming a release layer is more than 10 wt%, high viscosity of the composition for forming a release layer may cause uneven leveling, so that thickness uniformity of the release layer may be deteriorated.

For example, as the solvent used in the composition for forming a release layer, a mixed solvent of heptane and methyl isobutyl ketone may be used.
As a method of coating the composition for forming a release layer on a substrate, an off-line coating method available in the art, such as bar coating, gravure coating, die coating, etc., may be used. The energy source for curing the composition for forming the release layer is not particularly limited, but heat treatment, ultraviolet irradiation or electron beam irradiation, which may be used alone or in combination, and heat treatment may be used alone or a combination of heat treatment and ultraviolet irradiation may be used.
The heating may be performed at 60 ℃ or higher under an air atmosphere. For example, the heating may be performed at 60 ℃ or more for 24 hours under an air atmosphere. When the heating is performed at less than 60 ℃, it is difficult to introduce a portion including the fluorine-containing silane compound to the surface of the particles.
The weight ratio of the inorganic particles to the fluorine-containing silane compound may be 1:1 to 20: 1. when the weight ratio of the inorganic particles to the fluorine-containing silane compound is within the range, the peeling force can be further reduced to achieve excellent light peeling property.
In the present specification, "substitution" is induced by replacing at least one hydrogen in an unsubstituted parent group with another atom or functional group. Unless otherwise specified, when a functional group is considered to be "substituted", it means that the functional group is substituted with at least one substituent selected from an alkyl group having 1 to 40 carbon atoms, an alkenyl group having 2 to 40 carbon atoms, an alkynyl group having 2 to 40 carbon atoms, a cycloalkyl group having 3 to 40 carbon atoms, a cycloalkenyl group having 3 to 40 carbon atoms, or an aryl group having 7 to 40 carbon atoms. When a functional group is described as "optionally substituted," this means that the functional group may be substituted with the above-described substituent.
In the present specification, the monovalent hydrocarbon group of C1-C10 means, for example, a linear alkyl group such as methyl, ethyl, n-hexyl, n-octyl or n-decyl group, etc.; branched alkyl groups such as isopropyl, tert-butyl, neopentyl, isohexyl, etc.; cyclic alkyl groups such as cyclopentyl or cyclohexyl, etc.; alkenyl groups such as vinyl and allyl; aryl groups such as phenyl or tolyl; or aralkyl groups such as benzyl or phenethyl and the like. Among them, when considering the availability of raw materials, it may be an alkyl group, and when considering the usefulness of products, it may also be a methyl group or an ethyl group.
In the present specification, the alkyl group of C1 to C20 may include, for example, a linear alkyl group such as a methyl group, an ethyl group, a n-hexyl group, a n-octyl group, a n-decyl group, or the like; isopropyl, tert-butyl, neopentyl, isohexyl and the like. Among them, when considering the availability of raw materials, it may be an alkyl group, and when considering the usefulness of products, it may also be a methyl group or an ethyl group.
