Description

A film for sticking on glass and preparing method

According to the present invention, the upper surface of the flexible polyvinyl chloride film having a gloss treatment is adhered to the support layer through an adhesive, so that the printing layer is easily attached to the glass even if the printing layer is formed on the upper surface of the film. The present invention relates to a film for attaching the printing surface glass to prevent the deformation of the chloride film and its manufacturing method.

Glass attachment film is used as a substitute for curtains to make it difficult to see inside, or as a decoration for glass. In some cases, glass is used in consideration of safety to prevent fragments from splashing when the glass breaks. It is also widely used for advertisements attached to building glass.

The most popular glass adhesive films on the market are printed with various opaque patterns such that the back side of the glass is not visible on the polyester film or embossing the surface of the hard polyvinyl chloride (PVC) film. After the adhesive coating process to ensure that the PET film or rigid PVC film adheres to the glass, another PET film is attached to protect the adhesive coating surface again. When the product is used by the consumer, the PET film attached to the adhesive coating side is separated, and then the adhesive coating side is attached to the glass.

However, since the product is attached to the glass by using an adhesive, the adhesive may cause chemical change when used for a long time, and the decorative film may be wrinkled. If the decorative film is removed and then another product is attached, the decomposed adhesive remaining on the glass Removal is a major problem. In addition, if the size of the printed PET film, transparent PET film, or embossed hard PVC film is large, a large area must be attached, and the film is attached to the glass several times to eliminate air bubbles formed between the glass surface and the film. The adhesive process was very difficult because the adhesive had to be repeatedly removed and reattached, and clean removal of the film was very difficult.

Thus, in recent years, a lot of soft PVC films are attached to glass without adhesive.

However, flexible PVC films have too high tensile elongation and molding shrinkage so that they are not easily deformed but also have significant limitations in forming printed layers. That is, there was a problem that cannot be used in a plotter or an inkjet printer.

In order to compensate for the above problem, a release paper having a pressure-sensitive adhesive was attached to the soft PVC film, and when attached to glass, the soft PVC film was separated from the release paper, and only the soft PVC film was attached to the glass.

However, when the size of the soft PVC film is also increased, the prior art is deformed due to the large tensile elongation of the soft PVC film when attached to the glass, and does not adhere evenly to the glass. Even when changing, a problem arises in that the shape is easily deformed when the film is separated from the glass.

In addition, since the opposite side on which the printing layer is formed in the soft PVC film should be attached to the glass, the printing layer and the film can be easily damaged by outsiders when attached to the outdoor side of the glass, In some cases, the print layer may be exposed to be easily damaged or contaminated.

The present invention is to solve the problems as described above, and forms a rigid support layer on the lower surface of the flexible polyvinyl chloride film, so that the deformation of the form does not occur even if the glass adhesion film is repeatedly attached and detached to the glass. To provide a printing surface glass adhesion film and a method of manufacturing the same, by forming a printing layer on the gloss-treated upper surface of the flexible polyvinyl chloride film, the printing surface is firmly attached to the glass, and the construction of a large glass adhesion film is extremely simple. The purpose is.

In addition, another object of the present invention is to provide a printing surface glass-attached film and a method of manufacturing the same, which provide a refreshing feeling of forest bathing to indoor users by forming a printing coating layer to which phytoncide essential oil is added on a lower surface of the support layer.

In order to achieve the above object, the printing surface glass-coated film of the present invention includes a soft polyvinyl chloride film having an upper surface polished; A printing layer formed on an upper surface of the soft polyvinyl chloride film that has been polished; An adhesive formed on the lower surface of the soft polyvinyl chloride; And a support layer formed on the bottom surface of the adhesive, wherein the print layer is attached to glass or a synthetic resin plate.

In addition, the manufacturing method of the film for printing the printing surface glass of the present invention comprises: a first step of passing a soft polyvinyl chloride between a polished steel roller and a rubber roller to luster the upper surface of the soft polyvinyl chloride film; A second step of applying an adhesive to an upper surface of the support layer; Attaching the support layer to the lower surface of the flexible polyvinyl chloride film through the adhesive; And a fourth step of forming a printing layer on an upper surface of the soft polyvinyl chloride film that has been polished.

Since a rigid support layer is formed on the lower surface of the flexible polyvinyl chloride film, even if the glass attaching film is adhered to the glass repeatedly, the deformation of the flexible polyvinyl chloride film does not occur, and printing is performed on the upper surface of the flexible polyvinyl chloride film. Since the printing surface is firmly adhered to the glass by forming a layer, there is no fear of damage or contamination because the printing layer is not exposed, and the construction of a large glass attachment film is very simple.

Forming a printing coating layer is added to the phytoncide essential oil on the lower surface of the support layer has an effect that gives the indoor user a refreshing feeling of forest bathing.

In addition, when the light diffusion layer is formed on the lower surface of the support layer, not only the shape of the light source located in the interior of the glass is exposed as it is, but also the light of the light source is dispersed to improve the sharpness of the printed layer. Can greatly improve.

Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description will be omitted.

The printing surface glass adhesion film according to a preferred embodiment of the present invention, as shown in Figure 1a includes a soft polyvinyl chloride film 10, the print layer 20, the adhesive 30 and the support layer 40, The print layer 20 is attached to the glass or synthetic resin plate.

The upper surface of the flexible polyvinyl chloride film 10 is polished. The surface is processed very smoothly like a glass surface, and the surface of the flexible polyvinyl chloride film can be injected or extruded into a mold having a smooth polish, and then polished. The soft polyvinyl chloride in a state can be passed between the polished steel roller 11a and the rubber roller 11b or the matt steel roller to perform a gloss treatment on the upper surface of the flexible polyvinyl chloride film 10. Can be processed. At this time, the polished steel roller (11a), rubber roller (11b) and the matte steel roller may rise slightly due to the temperature of the soft polyvinyl chloride, but in order to easily peel off the soft polyvinyl chloride film from the roller at room temperature It can be maintained, and the film 10 can be naturally cooled after the roller passes.

At this time, in order to form a smooth surface, it is preferable to quench the soft polyvinyl chloride film 10 at a temperature of -20 to 0 ° C. after passing through the roller. It can be prevented from deforming, resulting in a smoother polished surface. By applying a gloss treatment to the soft polyvinyl chloride film 10 as described above, a clear print layer 20 can be formed and the print layer 20 can be firmly attached to the glass or synthetic resin plate without adhesive.

In addition, the flexible polyvinyl chloride film 10 is classified according to the content of the plasticizer, generally, when the content of the plasticizer is less than 10% by weight, it is hard, and when it is 10-30% by weight, it is classified as soft when it exceeds 30% by weight. do. That is, in the case of a flexible polyvinyl chloride film having a plasticizer content of more than 30% by weight, it may be attached to glass or the like without an adhesive, but it is preferable to keep the content of the plasticizer at 40 to 60% by weight, and the content of the plasticizer is 40% by weight. If it is less than%, the adhesion to glass or the like after the printing layer 20 is formed, and if it exceeds 60% by weight, the tensile elongation rate and the mold shrinkage rate become too large, which causes considerable difficulty in processing.

Instead of the soft polyvinyl chloride film 10, a film that is soft, such as a urethane film, and can be attached to glass or the like without an adhesive, can be widely used, and the thickness of the film 10 is about 50 to 300 µm and 100 to 200 µm. Degree is preferred.

An adhesive 30 is formed on the lower surface of the flexible polyvinyl chloride film 10, and any one capable of firmly bonding the flexible polyvinyl chloride film 10 and the support layer 40 may be used, and a hot melt adhesive may be used. The adhesive 30 is applied to the upper surface of the support layer 40 with a thickness of about 5 to 30 μm and adheres to the lower surface of the film 10, and about 7 to 10 μm is appropriate.

A support layer 40 is formed on the lower surface of the adhesive 30, and the support layer 40 is made of transparent or colored polyethylene terephthalate (PET), polyethylene (PE; poly ethylene), and polypropylene (PP). ), A synthetic resin film such as OPP (Oriented Poly Propylene) is used, and the thickness of the support layer 40 is about 50 to 200 μm. Substantially, if the thickness of the support layer 40 is less than 50 μm, deformation of the support layer 40 may occur when the adhesive is cured, and if it exceeds 200 μm, the support layer 40 may be considerably expensive, and the supply and winding portions described below may be used. Also, restrictions may be followed, resulting in reduced productivity. In addition, a nonwoven fabric or synthetic paper (polypropylene paper) or the like may be used as the support layer 40.

A print layer 20 is formed on the top surface of the flexible polyvinyl chloride film 10 that is polished. The print layer 20 should be formed of oil-based solvent ink, and in the case of water-based ink, the print layer 20 may be formed of glass or the like. It cannot be used because it is not attached. In this case, it is preferable to use an eco-solvent ink which is an ink containing an eco-friendly solvent.

As illustrated in FIG. 1B, a colored, particularly white, printed coating layer 50 may be formed on the bottom surface of the support layer 40 so that the printed layer 20 may be clearly visible, and the printed coating layer 50 may have 0.1 to phitonched essential oil. May contain 5% by weight, phytoncide essential oil has an antiviral and antifungal effect, is an environmentally friendly antimicrobial material mainly extracted from natural cypress, can be used safely harmless to the human body. When the phytoncide essential oil is added less than 0.1% by weight, the antimicrobial effect is not sufficient. When the phytoncide essential oil is added in excess of 5% by weight, the physical properties of the printing coating layer 50 cannot be obtained. In view of this, it is preferable to determine the addition amount. Since the phytoncide essential oil is added to the printing coating layer 50 which is in contact with the interior of the glass, the antibacterial effect is excellent, and indoor users can feel a refreshing feeling of taking a forest bath.

The light diffusion layer may be formed in place of the printing coating layer 50. At this time, the shape of the light source located in the interior of the glass is exposed as it may interfere with the advertising effect of the printing layer 20, especially at night, the light diffusion layer formed on the lower surface of the support layer 40 is light diffusing power and itself The hiding power is improved to prevent the shape of the light source from being exposed through the printing layer 20, and the light of the light source is dispersed to improve the sharpness of the printing layer 20.

At this time, the temperature of the steel roller (11a) may be slightly increased due to the soft polyvinyl chloride, but it is preferable to maintain at room temperature, the lower surface of the film 10 is adhered to the support layer 40 through the adhesive 30 It is preferable not to perform a gloss treatment for this purpose.

After the first step, a fifth step of quenching the soft polyvinyl chloride film 10 by passing it through the cooling unit 70a at a temperature of -20 to 0 ° C. may be added. As it cures, it can be prevented from being deformed slowly, thereby obtaining a smoother surface than natural cooling.

The second step is a process of applying the adhesive 30 to the upper surface of the support layer 40, the gravure (Comma), comma (reverse roll), kiss roll (Kiss Roll) by the coating portion (30a) ), Spray (spray) or mayor (Meyer bar) coating method, the adhesive is applied, and the adhesive 30 may be a solvent type, emulsion, water-soluble, hot melt adhesive, acrylic solvent is preferred among the solvent adhesive In addition, a hot melt film may be used as the hot melt adhesive, and in the case of a hot melt film, a hot melt film may be supplied between the flexible polyvinyl chloride film 10 and the support layer 40 instead of the process of applying the adhesive 30. .

In the third step, the support layer 40 having the adhesive 30 formed on the lower surface of the flexible polyvinyl chloride film 10 is attached by the lamination part 40a, and when the hot melt film is used, the film 10 into which the hot melt film is inserted ) And the support layer 40 can be attached by passing through the heated roller which is the laminated part 40a, and it is preferable to heat the roller contacting the support layer 40 so as not to damage the upper surface of the polished film 10. .

After the third step, a color printing coating layer 50 having various background colors is formed on the bottom surface of the support layer 40 by the coating unit 50a such as silk printing, gravure printing, roll printing or pad printing. Six steps may be added, and a light diffusing layer may be formed in place of the printing coating layer 50, and the light diffusing layer is applied in the same manner as that of the adhesive 30 and dried at a temperature of about 70 to 130 ° C. .

After the third or sixth step, the glass attachment film may be wound and stored in the winding unit 60, and may be cut into a required size in the winding unit 60, and then softly polished by a plotter or an inkjet printer. A fourth step of forming the printing layer 20 on the upper surface of the polyvinyl chloride film 10 may be performed. At this time, since the rigid support layer 40 is attached to the lower surface of the flexible polyvinyl chloride film 10 through the adhesive 30, the stretching or contraction of the film 10 does not occur.

In addition, the flexible polyvinyl chloride film 10 that is continuously polished through the same method as the method of forming the print coating layer 50 without sensing the film for attaching the glass, which has been completed by the third or sixth steps, to the winding unit 60. The fourth step of forming the print layer 20 on the upper surface of the can be carried out, and after the fourth step can be cut to the required size can be used to attach the print layer 20 to the glass.
