The present invention relates to a decorative sheet having a three-dimensional effect, and to a decorative sheet having a three-dimensional effect having a three-dimensional effect and a gloss effect by having a printed layer and a matte or glossy coating layer is displayed three-dimensional.

As is well known, the decorative sheet is mainly used as a surface finishing material that protects the material and expresses the appearance in various colors and textures, and is often used as a material for decorating the surface of interior building materials or furniture desks.

The decorative sheet is manufactured by a general coating or laminating method, and the laminating film has an adhesive type and an adhesive type, and melamine sheet, paper, and PVC, depending on the material used. Can be divided into PP decorative sheet. Recently, a decorative sheet in which a transparent film made of polyethylene terephthalate (PET) or polypropylene (PP) is added to the uppermost layer of the decorative sheet is used. At this time, a print layer is formed under the transparent film using gravure printing. On the transparent film, an embossing treatment may be performed to add a three-dimensional effect.

In addition, decorative sheets can be classified into overlay, wrapping, membrane, and edge, and overlay is a medium density fiberboard for furniture or construction materials. It is generally used on the flat top of particle board (PB) or particle board (PB), and it is used for the part that needs to be curved, such as narrow sash or molding part.

In addition, the membrane is used for general furniture or doors with a lot of curved processing, and the end is used for corners of furniture or desks or curved surfaces of upper plates, and recently, decorative sheets for iron plates are used on the exterior of electronic products or other metal griddles.

The plasticizer may be used alone or in combination of dioctylphthalate (DOP) or an epoxy plasticizer, and the stabilizer may be a complex stabilizer of cadmium-barium-zinc-based or barium-zinc-based. It can be given a decorative effect by using the gravure printing method on the top and bottom. When printing on the lower and upper portions of the transparent film to which the PEARL pigment is added, as compared to the general transparent film forming the printing layer, the three-dimensional effect that appears as the pearl (PEARL) pigment may be added to increase the stereoscopic effect.

The easy film 10 and the transparent film 30 can be plywood and embossing due to the characteristics of the thermoplastic PVC resin, and the easy film 10 and the transparent film 30 are rolled using calender or extruded using TiDy. Can be produced by.

The second printed layer 40 is formed by printing the final final frequency by a gravure printing method to be synchronized with the printed pattern of the first printed layer on the upper surface of the transparent film 30.

The surface treatment layer 50 is formed through a gravure printing method, and is coated on the second printed layer 40 using a printing roll having the same pattern as the printed pattern formed on the second printed layer 40. Partial coating to form a glossy effect that is synchronized with the printed pattern. In addition, the embossed layer 60 may be positioned on the upper surface of the surface treatment layer 50 as shown in FIG. 3. The embossed layer 60 may also be formed to have a concave-convex shape in the same shape as the printed pattern, thereby adding an effect synchronized with the printed pattern.

The treatment agent used in the present invention uses a urethane-based matt or glossy type, the thickness of the coating is preferably 1㎛ ~ 100㎛. If the coating thickness is out of the above range it is difficult to coat the surface treatment agent may cause problems in workability.

In addition, if each coating thickness is less than 1㎛ coating effect is insufficient, if the coating thickness is more than 100㎛ the drying speed is slow and workability is not good.

The non-glossy treatment agent is urethane-based, and is prepared by blending 80 to 120 parts by weight of a urethane resin-based main part, 5 to 15 parts by weight of an acid curing type curing agent, 1 to 10 parts by weight of silicone polyacrylate, and 20 to 40 parts by weight of a solvent. For example, the weight ratio of the hardener to the main portion is about 10: 1.

Specific composition of the main part is a polyurethane resin 40 ~ 60% by weight, as a matting agent for gloss control 2 ~ 8% by weight of silica, 30 ~ 45% by weight solvent, as a lubricant to improve the scratch resistance by reducing the friction coefficient of the surface 0.5-2% by weight of a polyether-modified dimethylpolysiloxane copolymer solution of silicone type, 0.5-2% by weight of a polysiloxane solution as an antifoaming agent to remove unnecessary bubbles generated when mixing raw materials, and methylate melamine formaldehyde of melamine amino resin series as a crosslinking agent ( -N-CH2OCH3CH2O-CH3) 3-8 weight%. The polyurethane resin has a degree of polymerization of 500 to 900, -OH group value of 3 to 7%, and the resin type includes a hard type and a soft type, in order to satisfy both ductility and scratch resistance at the same time hard and soft type Mixed at an appropriate ratio of about 5: 5. Solvents used in the main part include methyl ethyl ketone, toluene and xylene, and one or two or more of them are selected and used.

In addition, the acid-curable curing agent portion contains 30 to 50% by weight of paratoluene sulfonic acid, 25 to 45% by weight of ethyl acetate, 25 to 35% by weight of isopropyl alcohol.

In addition, as the solvent, one or two selected from methyl ethyl ketone and toluene is used, and is used for proper viscosity control and speed of drying.

The matt or gloss treatment agent is coated on the second print layer 40 using the same printing roll as the print pattern formed on the second print layer 40 using the gravure printing method. By coarse partial coating, the surface treatment layer 50 having the gloss effect synchronized with the printed pattern is completed.

When the surface treatment layer 50 is formed, when the surface treatment agent to be coated is glossy, the portion to which the surface treatment agent is coated becomes glossy and the portion that is not coated becomes relatively matt. On the contrary, in the case of the matte surface treatment agent, the coated part becomes matt and the uncoated part becomes relatively gloss, causing a gloss difference due to partial coating. That is, by the printing roll of the same type as the printed pattern, the portion coated with the surface treatment agent and the non-coated portion are divided, so that the glossy effect is synchronized with the printed pattern and the gloss and matte effects coexist. The stereo effect is further doubled.

The printed layers 20 and 40 and the easy film 10, the transparent film 30, and the surface treatment layer 50 thus manufactured are decorated by plywood and embossing through a thermal plywood machine in the following manner. The sheet is produced.

First, the film to be laminated is sufficiently heated using a heating drum or oven at 140 to 170 ° C. Subsequently, plywood and embossing are performed by applying pressure using an embossing roll having an uneven shape or an enamel roll having an enameling treatment in the same shape as the printed pattern formed on the second printed layer 40. At this time, the embossing roll having the same concavo-convex shape as the printed pattern will have the effect of being synchronized with the printed pattern until the embossing is produced during plywood and embossing.

Therefore, the first printing layer and the second printing layer are formed on both sides of the transparent film containing PEARL pigment, respectively, and are synchronized with the printed pattern of the printing layer, and have a gloss effect in which matt and gloss effects coexist. By forming a surface treatment layer, and additionally imparted to the embossing to be synchronized with the printed pattern, it is possible to manufacture a decorative sheet having a very excellent tuning stereoscopic effect.

Hereinafter, the present invention will be described in detail through examples, and the contents of the present invention are not limited to the following examples.
