Description

{Foamed PE Wall Paper And Its Producing Method}

The present invention relates to a PE foam wallpaper and a method of manufacturing the same. More particularly, the present invention relates to a PE foam wallpaper and a method of manufacturing the same, Wallpaper and a manufacturing method thereof.

In recent years, a wallpaper made of a PE (polyethylene) foamed resin having a good processability and a low price has attracted a great deal of attention in place of vinyl chloride resin, which is relatively weak in adhesive strength and low in stability, .

This foamed PE is extrusion-molded by adding a foaming agent to PE. Since it has good weather resistance, it hardly changes with time, does not generate toxic gas at the time of ignition, is excellent in heat insulation property, waterproof property and buffering property, But also widely adopted as wallpaper and mat.

As an example thereof, wallpaper using polyethylene or ethylene vinyl acetate resin and a method for manufacturing the same (Patent No. 10-0359493) can be mentioned. This wallpaper has a laminated structure by a base layer 110, a foam layer 130, a print layer 140, and a surface decorating layer 150 as shown by reference numeral 101 in Fig. 1, Polyethylene or ethylene vinyl acetate resin is used for the foam layer 130. In order to enhance the physical properties of the foam layer 130 and to impart ease of application, a base layer 110 made of paper or cloth is attached under the foam layer 130 , The printing layer 140 and / or the surface decorating layer 150 are formed on the foam layer 130 to compensate for the low workability of the foam layer 130.

Therefore, in order to apply the wall paper 101 to the wall surface, the adhesive agent must be applied to the base material layer 110 or the surface of the base material 110, so that the construction work is complicated and the construction time is long.

In addition, since the printing layer 140 and / or the surface decorating layer 150 are provided to enhance the decorative property of the outer appearance, the manufacturing cost is increased and the weight is increased, which makes handling uncomfortable during transportation and construction.

The wallpaper 101 of the conventional wallpaper 101 is vulnerable to invasion by the substrate layer 110 and the foam layer 130. Therefore, when the indoor wall surface becomes wet due to temperature difference between indoor and outdoor winter, or when the indoor humidity becomes high, The foam layer 130 formed thereon is discolored due to moisture or mold caused by moisture, and is severely damaged.

KR 10-0359493

In order to achieve the above object, the present invention provides a PE foam sheet molded with an outer surface; A film layer thermally laminated on an outer surface of the PE foamed paper before forming the outer surface of the PE foamed paper; A deposition foil formed by depositing a metal source on the inner surface of the PE foam paper; An adhesive layer formed by applying a pressure-sensitive adhesive on the inner surface of the vapor deposition chamber; And a releasing sheet attached to the inner surface of the adhesive layer and protecting the adhesive layer until the adhesive layer is pasted to the surface of the adhesive, wherein the film layer is made of LDPE to which an antifungal agent is added.

Further, it is preferable that the PE foamed article is formed such that its outer surface has a rough wall-like irregularity.

The adhesive layer is preferably prepared by adding an antifungal agent to an aqueous adhesive.

The present invention also relates to a method for producing a laminated film, comprising the steps of: laminating a film layer made of an antifungal-added LDPE on the outer surface of a PE foam paper; A foaming paper forming step of forming the outer surface of the PE foam paper in which the film layers are thermally joined on the outer surface in the film layer laminating step, so as to have irregularities in a rough wall shape; Forming a vapor deposition foil on an inner surface of the PE foamed paper having an outer surface formed in the forming step; An adhesive layer forming step of forming an adhesive layer by applying an anti-fungal agent-added aqueous adhesive to the inner surface of the deposition foil formed in the deposition step; And a release paper attaching step of attaching a release paper to the inner surface of the pressure sensitive adhesive layer formed in the pressure applying step to protect the pressure sensitive adhesive layer.

According to the PE foam wallpaper of the present invention, since the film layer is laminated on the outer surface of the PE foamed paper, the surface strength of the outer surface of the wallpaper can be improved. Thus, by increasing the porosity of the outer surface, Not only the decorative property of the outer surface can be greatly improved but also the surface elasticity is increased and the buffering performance is greatly improved.

Further, since the metal vapor deposition foil is deposited on the inner surface of the PE foam paper, the wall space can safely protect the installed space from electromagnetic waves.

Further, since the antifungal agent is added to the film layer and / or the adhesive layer, it is possible to prevent the mold from being generated even if moisture is present on the indoor wall surface.

Further, since the metal vapor deposition foil is formed on the inner surface of the foam paper, the moisture resistance is enhanced, and the foam paper can be more effectively protected from the moisture generated on the inner wall surface.

Another object of the present invention is to increase the strength of the wallpaper surface so that the entire surface can be compression-molded into various shapes.
