Description

Transparent decoration panels with metallic feel having digital printing layer

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transparent decorative panel having a digital printing layer. Specifically, a transparent and decorative image or pattern (hereinafter referred to as "image") formed by an inkjet printing method, a transparent decoration with improved metal texture effect and safety It is about the panel.

Conventionally, in the field of glass decorative sheet, an image formed of a groove or a piece of physically engraved or embossed on one side of the tempered glass sheet and the composite glass sheet is used as an interior material. However, these products are only partially used due to workability, productivity and safety issues.

In addition, a conventional method of painting on the back surface of a general glass plate and a tempered glass plate using a silk screen and powder (spray) paint containing metal particles is used. However, this method is not safe due to the scattering of fragments when the glass is broken by a strong impact, and the scratches, scratches, and chemical resistance are weak, so that the coating material is peeled off or affected by construction materials such as adhesives, tapes, and silicones used in construction. The immersion phenomenon occurs, due to the nature of the powder coating, the depth and three-dimensional feeling of the metal is inferior, a large space is required for the coating and drying of the glass plate, there is a disadvantage that harms the health of the worker due to the organic solvent used during the coating.

Korea Utility Model Registration No. 421433 is printed in polyethylene green terephthalate (PET) film in light green to make glass decorative sheet with metal texture, and then coated with a small amount of aluminum paste in a transparent adhesive, and then PVC sheet After laminating with and through a three-day maturation period, a method of forming a pressure-sensitive adhesive layer again to adhere to the glass is disclosed. This can be expected aesthetic effect of the metal, but the manufacturing process is complicated due to the high defects in manufacturing, and the disadvantages of the image or pattern development and printing restrictions, color expression power, clarity is poor, adhesives, tape, silicone used in the construction As the stain occurs after construction due to construction materials such as construction materials, the incidence rate is high, making construction difficult.

Korean Patent Publication No. 2002-73771 describes a method of laminating printed PVC sheets and glass. However, this technique is not safe because the adhesive layer that acts as a buffer when glass breaks due to strong impact is thin. In order to solve this problem, increasing the thickness of the glass panel or using the multilayer glass, weight and handling difficulties occur, and because of the use of PVC sheet, it is vulnerable to changes in the atmospheric environment such as heat, temperature, humidity, and ultraviolet rays, and is environmentally friendly. This is not a disadvantage.

Korean Patent Registration No. 746133 describes a method of transferring a cross section of glass using a transfer film having an image formed thereon. Such transfer method is limited to the transfer film printed with the image desired by the consumer, and most of the transfer film for glass panels depends on imports, which makes it difficult to develop the image, and it is difficult to control the thickness of the transfer printed layer, resulting in scratches. To reduce the transfer rate due to the tearing of the transfer film and damage to the transfer image or pattern, there is a problem in that product defects increase and productivity is lowered.

Republic of Korea Patent Publication No. 2009-63394 has formed an impact protection layer made of PVC sheet and rubber in the glass decorative structure to prevent breakage due to strong impact, and the interior layer that implements the image through the screen printing method The formed glass interior decoration material is disclosed. However, in this decorative material, the overall adhesion of the glass decorative structure is reduced, so that the peeling phenomenon of the film is likely to occur during the construction, and the interior layer formed the image by the screen printing method is due to the image limitation and screen ink characteristics due to the screen printing method. Print color expressiveness, detail and subtlety are not enough to maximize the aesthetic, advertising or promotional effects, and there is a disadvantage that a large space for screen printing is required.

Korean Patent Registration No. 898206 discloses a method for manufacturing an interior panel using a UV curing printing method. In this method, substrates such as canvas, silk, acrylic plate, artificial leather, and the like are attached to a glass panel in order to express an image, and then UV cured printing is applied on the upper surface, and a protective coating layer is formed thereon. This method, however, is not uniform in the thickness of the canvas and artificial leather used to form the image, which may cause a deterioration in adhesion when attached to the glass panel. Due to the nature of the curing printer, a large working space is required, and there is a complicated process of forming a protective coating layer again. In addition, unlike inkjet printers, UV-cured printers are expensive, and the ink used for UV-cured printing has limitations in maximizing aesthetic effect due to lack of detail, detail, and color expressiveness compared to inks used in other digital printing methods. There is a disadvantage in that the price competitiveness is lowered due to poor production efficiency.

Accordingly, one object of the present invention is to provide a transparent decorative panel which can freely and economically form a delicate and clear image.

Another object of the present invention is to provide a transparent decorative panel having a metal effect having a three-dimensional feeling and a depth of metal feeling.

First, a shielding layer, a metal effect coating layer, and an ink receiving layer are formed on the base layer film according to the above method. Using an inkjet printer, a printing layer is formed on the ink receiving layer, an adhesive layer is formed, and then a protective film is formed on the adhesive layer. Thereafter, a backside treatment layer is formed on the backside of the base layer film. Subsequently, referring to FIG. 2, for example, a shielding layer and a metal effect are sequentially formed on a PET base layer film having a thickness of 20 to 100 μm with a backside treatment layer having a thickness of 1 to 5 μm including a polymer having an organopolysiloxane unit. The metal-like digital decorative film fabric 100 having the coating layer, the ink receiving layer, the printing layer, and the adhesive layer is mounted on the fabric supply rollers 200 and 210. Separately, the transparent glass panel 110 prepared beforehand is put into the washing machine 300 to be washed and then passed through the dryer 500, and then transferred along the automatic conveyor 400. Transparency that has been moved through the adhesive layer and the conveyor of the digital decorative film fabric 100 supplied by the fabric supply rollers 200 and 210 while peeling and removing the protective film coated on the adhesive layer of the digital decorative film fabric 100. Passing the compression roller 600 in the state in which the glass panel 110 is laminated, the both are first integrated, and then an additional pressure is further applied in the auxiliary compression roller 610 to make the transparent glass panel 110 and the digital decorative film fabric 100 ) Can be more firmly integrated. In this case, the compression roller 600 may be heated by water vapor or a heat generating resistance to increase the adhesive strength of the transparent glass panel 110 and the digital decorative film fabric 100 by applying heat during compression. As the transparent panel and the digital decorative film fabric are attached and integrated under the conditions of heating pressurization as described above, it is excellent in preventing the scattering of the transparent panel fragments in case of breakage due to a strong impact. . Therefore, according to the above-described manufacturing method, it is possible to mass-produce a transparent decorative panel with high productivity and good aesthetics and three-dimensionality by an inkjet type digital printing process and a process of integrating a continuous digital decorative film fabric and a transparent panel by heating and pressing.
