Abstract

The present invention relates to a micro gravure having a control means for uniformly flowing air and intensively emitting the quantity of UV light. When a base film which is a first supplied sheet and a release film which is a second supplied sheet are combined through the micro gravure, both the films which are the first and second supplied sheets are transferred through a heating chamber of a drying unit after micro-coating of an adhesive solution, and enable to secure uniform adhesion performance with an air flowing apparatus and a UV intensive emitting apparatus, thereby securing excellent quality of a completed film, wherein securing the degree of adhesion of an adhesive layer of the base film is considered to be the most important with a coating technology (since the films can be bonded well or not depending on the thickness or characteristic film difference desired by customers, wrinkles can be generated during the combination, and sticking phenomenon and tearing phenomenon can occur during expost splitting).

Description

(Microgravure with heating vantilator and UV lamp) equipped with uniform air blowing rate injection and ultraviolet light intensity concentration irradiation control means,

The present invention relates to a method for bonding a first base paper and a second paper-feeding release film to each other through a microgravure device, It is essential to secure the adhesion of the base film to the adhesive layer (due to the stickiness or the difference in the characteristics of the user's specialty film, the wrinkles are generated and the sticking phenomenon occurs and the tearing phenomenon occurs in the after-stripping) The film is transported through the heating chamber of the drying section after the micro-coating of the film, and the blowing device and the ultraviolet focusing device can secure homogeneous adhesion performance, thereby ensuring excellent quality of the finished film. Uniformity injection and ultraviolet light intensity concentration irradiation control means.

Various apparatuses and methods for coating a coating liquid on a coating material such as paper, synthetic resin film, and fabric have been found.

Typical coating methods include Mayer Bar Coating method and gravure coating method, and a typical example of the gravure coating method is Doctor Chamber Type Gravure coating method.

In the gravure coating method, the coating liquid is supplied to the gravure roller, and the gravure roller is rotated in contact with the material to be coated, but is rotated in a direction opposite to the moving direction of the material to be coated, thereby coating the coating liquid on the gravure roller .

Accordingly, the gravure coating method is preferred because it has a lower loss of coating solution and uniform coating as compared with other coating methods.

On the other hand, in recent years, various display devices such as a television, a computer, a word processor, or a car navigation have been required to uniformly etch, or even partially and uniformly etch, or polish the entire surface of a thin film glass. It should be washed in acidic solution.

Furthermore, the touch panel type display device visually transmits various image information such as characters and pictures to the user through the display panel P processed to be ultra-thin, and a pattern such as a transparent electrode is formed on the surface of the thin film glass Therefore, it is necessary to precisely pay close attention to the cutting, such as cutting into small pieces along the pattern boundary and smoothly finishing the cut end face by means of etching or the like.

However, if the processed glass is put into the fluoric acid solution, it will naturally damage the surface of the glass. In order to prevent such damage as the transparent electrode, it is necessary to use only a specific part For the purpose of masking for etching, a protective film made of a material that does not dissolve in a fluoric acid solution (that is, a PET film or a PVC film having an adhesive layer on one side) is attached to all or a part of the glass surface, .

However, the PET film is weak to acid and has a limitation in achieving the desired purpose, and the PVC film has a strong acidity and a high surface viscosity, which causes the PVC films to stick to each other later.

As a second prior art relating to a method for producing an acid-resistant protective film for solving such a problem, Korean Patent Application No. 2012-0044101 (protective film for smart glass thin film and its production method) and Korean Patent Application No. 2012-0052932 (A method for producing a protective film for a smart glass thin film).

The points of both layers are common, and only the order of lamination of the PVC layer, the PE layer and the PET layer is different.

That is, when the PVC film adheres to the glass surface with the acid-resistant protective film, when the pieces of the glass with the PVC film attached thereto fall into the solution below the PVC, The use of a protective film in which a highly active PE film and a PVC film are laminated is intended to solve the problem that the PVC sticks to each other as described above.

However, since the above-mentioned conventional techniques are such that the PVC film and the PE film are merely heated and pressed together, the two film layers (one side of the PVC film and one side of the PE film) having completely different physical properties do not stick to each other and stick together However, if it is heated to about 80 ° C., which is close to the melting point of PE, the PE film will not adhere well, but the PE film itself may have wrinkles or sticking problems do.

Further, in the above-mentioned prior arts, a pressure-sensitive adhesive layer is formed on the other side of the PVC film (the opposite side of the PE film) and a PET film layer is formed as a release layer. And there is no detailed explanation as to how to dry them under certain conditions, and it is stated that they only pass different chambers of 45 to 60 ° C or 50 to 70 ° C, and when using general acrylic pressure-sensitive adhesives or commonly used solvents, Sufficient volatilization of the solvent is not possible and pores remain, which makes it difficult to form an appropriate viscosity and uniform adhesive layer.

If a proper viscosity and a uniform pressure-sensitive adhesive layer are not formed, not only the defective rate due to the residue of the adhesive partially remaining in the glass upon removal of the protective film after the work, but also the peeling itself may become difficult.

Furthermore, there is a problem in that when the film is wetted with a hydrofluoric acid solution, a minute gap is formed between the protective film and the glass, and the film is also directly etched.

On the other hand, Japanese Patent Application Laid-Open No. 2003-309088 (a method for producing a protective sheet for semiconductor wafer processing and a sheet thereof) as another conventional technique discloses that although not a glass protective film, a UV- Layer structure in which a second base film is laminated thereon and on the other hand a second ultraviolet curing type pressure-sensitive adhesive layer is formed on the other side of the first base film and a separator layer is formed thereon .

However, in the above-mentioned other prior arts, when the first base film is made of PVC and the second base film is made of PE, and the ultraviolet curing type first pressure sensitive adhesive layer is simply formed between the first base film and the second base film, There is a problem that wrinkles are generated in a PE having a high elongation at the time of lapping due to the ultraviolet curing type pressure-sensitive adhesive.

At this time, the vane tube is in the form of a flat ring band, its thickness is about 2 mm, and both ends of the inner circumferential surface are rounded to minimize the friction area when the air current is transported.

The target direction P is a swirl flow introduced while rotating, and corresponds to one point among the points flowing in the circumferential direction as the swirl flows into the inner circumferential surface of the blowing pipe. As shown in the figure, Means the direction of the inner peripheral wall of the air blowing pipe in the forward direction.

In this case, the swirl inducing member is, for example, a portion corresponding to the area D, which is the closest to the destination direction P, so that the flow of the airflow is maximized and the flow of the airflow decreases as the area C or A So that the collision is minimized at the moment of being suddenly deflected to the side wall of the blower pipe, and the noise is minimized.
