Description

Decorative transparent panel {DECORATIVE TRANSPARENT PANEL}

The present invention relates to a decorative transparent panel, and more particularly, to a decorative transparent panel having excellent durability and weather resistance, in which a plastic film printed with various patterns is attached to the back side of a transparent substrate such as glass, and the printed pattern is exhibited from the transparent substrate.

Decorative glass is obtained by adding a variety of patterns on the back of the glass, usually printed on the back of the glass by screen printing or the like to transfer the print using a transfer paper so that the pattern appears. Spray coating is also applied on the printed layer separately to add solid color and metallic effect.

However, in case of printing directly on the back of the glass, if the printing ink is a conventional organic material, there is a big difference in the coefficient of thermal expansion between the inorganic glass and the ink, so that the ink is separated from the glass or yellowing occurs after a long time. There was this. In addition, yellowing may be reduced by using an inorganic pigment in the ink. However, since the colorant to which the inorganic pigment is attached is an organic material, yellowing still occurs, and detachment from glass occurs, as in the organic ink.

In general, a specific printing method for printing directly onto a transparent plate such as a glass plate uses screen printing or transfer printing using a transfer sheet. Screen printing method does not have pattern development and size constraints, but it is difficult to apply complex patterns due to the characteristics of silk screen printing, which is usually done within 4 degrees. It is rarely applied except in cases.

In addition, the transfer printing method requires a pretreatment process to make the thermal transfer of the printed pattern well, and additionally requires a back coating layer to improve the hiding power under the transfer printing layer. When the glass plate is applied as a transparent plate when manufacturing in this manner, since the transfer film for glass is not produced in Korea, and the total amount is dependent on imports, the pattern of the transfer film is limited, so it is difficult to develop a separate pattern. There is a problem in the production of a large size to be applied for the interior. In addition, because the thickness of the transfer printing layer is thin, it is easy to damage the pattern of the printing layer due to the surface scratches generated during the handling process. The possibility of surface peeling and discoloration of the layer is high, and there is a problem that the safety of quality is much lowered.

In addition, spray painting to reproduce solid color and metallic effect is cheap, but many defects occur due to problems such as stain or discoloration of paint, and transparent like acrylic plate or polycarbonate plate. When plastic is used as a substitute for glass, chemical properties may cause problems such as staining and swelling.

On the other hand, instead of printing directly on the back of the glass as described above, a laminated glass tile that forms a printing layer on a separate plastic substrate such as a vinyl chloride resin sheet and laminates the glass is Korea Patent Publication No. 10-2002-0073771 It is disclosed in the call. However, the laminated vinyl chloride resin sheet and the glass plate lack mutual adhesive strength even if they are laminated by heat and pressure, and problems such as heat shrinkage and lack of moisture resistance of the vinyl chloride resin sheet in a high temperature post-processing process for use as a refrigerator door exterior material after plywood. Has occurred and is not yet satisfactory. In addition, there is a problem that it is difficult to apply due to the lack of weather resistance when using it as a building exterior material.

The present invention, in consideration of the problems of the prior art, can prevent the printed pattern of the printed layer from being damaged by scratching, simplifying the manufacturing process because a separate pretreatment process, an additional coating process for reinforcing hiding power is not required An object of the present invention is to provide a decorative transparent panel having excellent durability and weather resistance that can be printed through a transparent plate with various patterns without restriction of size.

The present inventors can reduce the heat shrink of the polyvinyl chloride sheet by interposing the adhesive or reinforcing film between the glass plate of the glass tile disclosed in Korea Patent Publication No. 10-2002-0073771 and the polyvinyl chloride sheet containing the printing layer, Solving problems such as low moisture resistance, and weather resistance and durability is also increased to find that it can be used not only for interior materials such as home appliances, but also for outdoor exterior materials, thereby completing the present invention.

The decorative transparent panel of the present invention has a structure in which a plastic sheet containing a printing layer is laminated on the back side of a transparent plate such as glass, such as the glass tile disclosed in Korean Patent Publication No. 10-2002-0073771, and is transparent. The plate and the plastic sheet are bonded at the time of plywood by the transparent adhesive layer. Such adhesion by the transparent adhesive layer reduces heat shrinkage of the plastic film such as polyvinyl chloride sheet, increases weather resistance and durability in the decorative transparent panel, and does not reduce the sharpness of the pattern emerging from the printing layer on the backside of the transparent plate.

The decorative transparent panel of the present invention may further interpose a transparent plastic film reinforcing layer between the plastic film including the transparent plate and the printing layer in order to further reduce the heat shrink of the plastic film and to further supplement weatherability and durability. Moreover, in order to reinforce adhesion of this transparent plastic film, a transparent adhesive agent can also be added and used.

In addition, the decorative transparent panel of the present invention may form a metallic coating layer by coating a coating material containing metal or metal oxide on the printing layer so that the pattern expressed by the transparent plate may appear as if it is a metallic material.

Therefore, the decorative transparent panel of the present invention may have a structure of the following type.

The first type is a structure including a transparent plate layer (1) / transparent adhesive layer (2) / printing layer (3) / plastic film layer (4) from above, as shown in FIG.

The sixth type is a transparent plate layer (1) / second transparent adhesive layer (2) / transparent plastic film reinforcement layer (6) / first transparent adhesive layer (2) / metallic coating layer (5) / printing layer (as shown in FIG. 3) / plastic film layer (4).

In addition, it is apparent that various conventional layers may be used to supplement the physical properties of the decorative transparent panel.

Hereinafter, each layer constituting the decorative transparent panel of the present invention will be described.

The transparent plate layer may be a glass, or a transparent plastic plate may be used, and the glass may be used all common glass products such as ordinary glass, tempered glass, laminated glass, and also the transparent plastic plate is polycarbonate panel, acrylic panel, polyethylene tere Phthalate panels and the like can be used.

Such a transparent plate layer may be used for various purposes, the transparent plate of a variety of thickness, it is suitable to represent the pattern that the transparent plate of 3 to 7 mm thick emerge from the lower printing layer. Particularly, for use as an exterior material of home appliances, 3 to 4 mm thick tempered glass or polycarbonate panel is preferable.

The adhesive or pressure-sensitive adhesive used for the transparent adhesive layer is selected from materials that can provide excellent adhesiveness to a plastic film containing a transparent plate such as glass and a printing layer while having transparency after curing. Preferred adhesives are one-component adhesives comprising a polymer selected from the group consisting of acrylics, urethanes, and esters, or two-component adhesives in which polyisocyanate is further included in the components of these one-component adhesives. This transparent adhesive layer can be formed by adding for adhesion with a transparent plate such as glass when the transparent plastic film reinforcement layer is added to the decorative transparent panel.

The thickness of each transparent adhesive layer can be set in consideration of workability and transparency, preferably 5 to 50 µm, more preferably 20 to 40 µm. When the thickness of each transparent adhesive layer is less than 5 μm, the adhesion is low, and the heat shrinkage of the plastic film is decreased, and the effect of increasing weatherability and durability is not increased in the decorative transparent panel. Is not economical because does not appear.

The plastic film layer is a layer on which a pattern of a decorative transparent panel is printed, and the pattern is exposed to the transparent plate from the printed layer. For this purpose, the plastic film layer may be a film made of a material such as polyester, polyvinyl chloride, polypropylene, or polyethylene. The use of 0.15 to 0.2 mm thick plastic films is advantageous for printing layer formation and adhesion processing with a transparent plate such as glass, and both transparent, translucent, or opaque films may be used, but they exhibit a clearer pattern and hiding power. It is preferable to apply an opaque colored film prepared by adding colored pigments rather than transparent for strengthening.

The printing layer formed on the plastic film layer may contain all kinds of printing methods, and among them, the printing layer may be formed using a gravure printing method.

In addition, a coating material containing a metal or a metal oxide may be coated on the printing layer on the printing layer to form a metallic coating layer. In particular, it is preferable to use aluminum metal powder for home appliance exterior materials, and its size is preferably 30 to 100 µm. Although the coloring agent of a coating material is not specifically limited, It is preferable to use the same thing as the material of a transparent adhesive layer.

The transparent plastic film reinforcement layer is an additional layer used to further reduce the heat shrink of the plastic film layer including the printing layer and further supplement weather resistance and durability, and the material is not particularly limited, but a polyester film or polyester Composite films, such as polyvinyl chloride, polyester / polypropylene, and polyester / polyethylene, are preferable, and a film containing polyester is particularly preferable. Since this film is used for the purpose of heat shrink reinforcement etc., although the thickness is not specifically limited, It is preferable to use the thing of 0.02-0.05 mm.

The decorative transparent panel of the present invention is manufactured by laminating a plastic film and a transparent plate layer on which a pattern is printed through an adhesive. The lamination method may use a conventional method of coating a transparent adhesive on a printed plastic film, and then laminating it with a transparent plate layer. In consideration of productivity, a plastic film and a transparent adhesive (adhesive), which have a pattern printed on them separately, may be used as paper, Alternatively, a method of forming a transparent adhesive layer by forming a transparent adhesive layer by laminating a release film coated on a release paper such as a polyester film and then plywood while removing the transparent plate layer and the release film may be carried out.
