The present invention relates to a Deco-Sheet having excellent surface texture and a method for producing the same.

In general, a decoration sheet (hereinafter referred to as a "decor sheet") refers to a sheet for expressing various decorations such as a wooden pattern, a marble pattern, and an abstract pattern in furniture such as a dresser and a sink.

The plasticized polyvinyl chloride material which is conventionally used as a material for a decorative sheet is excellent in physical properties and moldability, but it is necessary to use a chemical product which is likely to cause environmental problems. Therefore, a polyolefin-based resin such as a propylene-based resin, which has emerged as a substitute material therefor, is excellent in heat resistance and mechanical strength, excellent in chemical resistance and electrical insulation, and is widely used for applications such as plastic films and sheets have. However, the polyolefin-based resin has a problem that molding is difficult and appearance quality is poor.

On the other hand, when a decorative sheet is produced using a polyolefin-based resin, the decorative sheet usually has a surface protective layer formed to protect the outermost surface of the decorative sheet. Particularly, in order to improve abrasion resistance, scratch resistance and the like, it is known that a polyurethane resin is used for the surface protective layer or a UV curable resin is used.

But. The surface protective layer is usually flat and uniformly coated and is not stereoscopic, and has limitations in expressing the texture of a substrate such as marble or wood.

In order to solve the above problems, in the present invention, a decoupled sheet having excellent surface texture can be produced by forming the surface protective layer with primary and secondary UV coating layers, and the present invention has been completed on this basis.

Before describing the invention in more detail, it is to be understood that the words or words used in the specification and claims are not to be construed in a conventional or dictionary sense, It should be interpreted as meaning and concept consistent with the technical idea of the present invention. Therefore, the constitution of the embodiments described in the present specification is merely a preferred example of the present invention, and does not represent all the technical ideas of the present invention, so that various equivalents and variations And the like.

Hereinafter, preferred embodiments of the present invention will be described in detail so that those skilled in the art can easily carry out the present invention. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

Hereinafter, the present invention will be described in more detail.

1 shows a cross section of a decor sheet according to an embodiment of the present invention. 1, the decor sheet according to the present invention comprises a polyolefin-based printed fabric composed of a first primer layer, a polyolefin-based white or colored film layer, a second primer layer, a printing layer, and a third primer layer, And a polyolefin-based transparent film layer, and a fifth primer layer and a surface protective layer on the transparent film layer. Here, the surface protection layer is a layer according to the present invention, and is composed of a primary UV coating layer coated over the entire surface of the fifth primer layer and a secondary UV coating layer partially coated on the primary UV coating layer.

In the present invention, primer layers are respectively formed on the upper and lower portions of the polyolefin-based white or colored film layer, the print layer, and the polyolefin-based transparent film layer, and the second primer layer is formed between the polyolefin- And the first primer layer is a layer for improving adhesion to the adherend (MDF, PB, PVC, PP, wood, etc.) of the multi-layered decorative sheet according to the present invention. To increase the adhesive force.

According to the present invention, the third primer layer and the fourth primer layer serve to increase the adhesive strength between the printed layer and the polyolefin-based transparent film layer, respectively. In FIG. 1, the third primer layer and the fourth primer layer are both present. However, the third primer layer and the fourth primer layer may be present in only one layer. That is, the fourth primer layer may be directly adhered to the print layer without the third primer layer, or the polyolefin-based transparent film layer may be directly adhered to the third primer layer without the fourth primer layer.

According to a preferred embodiment of the present invention, it is preferable that the polyolefin-based printed fabric and the polyolefin-based transparent fabric are prepared separately, and then the two fabricated ends are laminated with each other for lamination. In this case, it is preferable that both the third primer layer and the fourth primer layer are present in order to increase the adhesive force between the print layer and the polyolefin-based transparent film layer. Actually, in the absence of the third and fourth primer layers, the polyolefin-based printed fabric and the polyolefin-based transparent fabric easily peel off in use. If there is no first primer layer, peeling with an adherend occurs.

As described above, the decor sheet of the present invention includes a polyolefin-based printed fabric, a polyolefin-based transparent fabric, and a surface protective layer. Here, the surface protection layer is composed of a primary UV coating layer coated over the entire surface of the fifth primer layer and a secondary UV coating layer partially coated on the primary UV coating layer.

The decor sheet according to the present invention improves the surface texture by forming a primary UV coating layer and a secondary UV coating layer partially coated on the primary UV coating layer, as compared with the case of forming a decor sheet with only the existing UV coating layer. As the surface texture is improved in the decor sheet according to the present invention, it is possible to express the surface texture (wavy pattern, ring pattern, stripe pattern, marble pattern, etc.) of natural marble or natural wood. In addition, the surface protection layer composed of the fifth primer layer, the first UV coating layer, and the second UV coating layer is superior in abrasion resistance and scratch resistance to the surface protection layer composed of the conventional single UV coating layer.

In the present invention, the polyolefin-based film layers are formed using a material such as polypropylene or a random copolymer of propylene and another olefin, and these can be generally used products known in the art or commercially available. The polyolefin-based film layers serve to provide mechanical properties such as hiding power, and / or gas barrier properties. These polyolefin film layers can be replaced with materials such as polyethylene terephthalate (PET) or polyvinyl chloride (PVC) to replace the function of the polyolefin film layers to be obtained in the present invention.

The primer layer is generally formed using a material such as a polyurethane, a polyisocyanate, a polyvinyl chloride, a polyester or the like, and it is possible to use an article generally known in the art or commercially available.

The print layer is generally formed by using a material such as polyurethane or polyvinyl, and is capable of imparting visually a design such as a marble pattern, a wood pattern or an abstract pattern, and imparting heat resistance, light resistance and weather resistance. Also, products commonly known in the art or commercially available can be used.

The surface protective layer is generally formed using a material such as acrylate or acryl urethane, and imparts stain resistance, scratch resistance, light resistance, weather resistance, and the like. As described above, the decor sheet according to the present invention improves the mechanical properties such as surface texture and abrasion resistance by forming a primary UV coating layer and a secondary UV coating layer partially on the primary UV coating layer.

According to the present invention, the coating material forming the secondary UV coating layer has higher thixotropy than the coating material forming the primary UV coating layer. In addition, the components of the primary UV coating layer can be selected from the group consisting of a combination of a 2-3 functional urethane acrylate having soft properties and a bifunctional and / or monofunctional monomer (e.g., hydroxypropyl acrylate, polyethylene glycol, oxybis diacrylate, Etc.) to enhance adhesion and wetting with the secondary UV coating layer by increasing the surface tension. In addition, the first UV coating layer is cured to a degree of 90% or less, preferably 80-90%, based on 100% of the total curing when curing, and then a second UV coating layer patterned in a predetermined pattern is formed. The primary UV coating layer and the secondary UV coating layer are then fully cured, thereby increasing the adhesion.

Preferable composition for the primary UV coating layer is 10-15% by weight of ethylene acetate, 10-20% by weight of hydroxypropyl acrylate, 1-5% by weight of 1- (hydroxycyclohexyl) phenyl methanone, 10 to 20 wt% of glycol 400 diacrylate, 1-10 wt% of oxybis diacrylate, 1-10 wt% of polyethylene, 10-20 wt% of urethane acrylate, 1-10 wt% of silica, 1-5% by weight of hydroxy-2-methyl-1- [4- (1-methylvinyl) phenyl] propanone, and the remainder being other additives. That is, the first UV coating agent may be any composition as long as it is a composition including a combination of various acrylates, a photopolymerization initiator, silica, etc., and a reactor is formed on the surface in a semi-cured state upon application. Those skilled in the art will be able to combine various acrylates, photopolymerization initiators, and silicas that can satisfy the above conditions.

In the primary UV coating layer, when silica is dispersed in a resin solution as a fine powder, it becomes finely agglomerated particles. When the coating is applied to an object, it forms irregularities on the surface of the coating film by drying and curing to prevent incomplete specular reflection, It shows a quenching effect that prevents our eyes from feeling light. That is, the silica may be any silica (for example, fused silica, precipitated silica, etc.) capable of exhibiting a quenching effect in the resin solution.

Preferable composition for the secondary UV coating layer is 10-15% by weight of ethylene acetate, 10-15% by weight of 2-hydroxyethyl acrylate, 1-5% by weight of 1- (hydroxycyclohexyl) phenyl methane, 1 to 5 wt% of diacrylate, 10 to 15 wt% of trimethylolpropane triacrylate, 20 to 30 wt% of acrylate resin, 1 to 5 wt% of urethane acrylate, and 1 to 5 wt% of fumed silica, 1-5 wt% of pentaerythritol triacrylate, 1-5 wt% of oligo [2-hydroxy-2-methyl-1- [4- (1-methylvinyl) phenyl] propanone] Additives, but are not necessarily limited thereto. That is, any secondary composition can be used as long as it is a composition having high thixotropy upon application, including a combination of various acrylates, a photopolymerization initiator, fumed silica and the like. Those skilled in the art will be able to combine various acrylates, photopolymerization initiators, and fumed silicas that can meet the above conditions.

In the second UV coating layer, the fumed silica serves to enhance thixotropy of the resin solution together with other acrylate resins. The thixotropy refers to the property that when the kinetic energy is applied, it changes from a gel to a fluid sol, but when it stops, it returns to the gel.

In the primary and secondary UV coating layers, the other additives are those conventionally used in the art, and may include defoaming agents, wetting agents, and the like.

In general, the formation of another UV coating layer on the UV coating layer tends to be easily detached by an external impact due to low adhesive force and / or adhesion between the two layers, or to easily peel off with the passage of time.

As described above, the coating forming the secondary UV coating layer may exhibit higher thixotropy by including other fumed silica than the coating forming the primary UV coating layer. However, in the present invention, a secondary UV coating layer having reactive residues (OH groups, etc.) and having high thixotropy on a semi-cured primary UV coating layer is formed and fully cured. The secondary UV coating layer having a high flushing property is adhered to the primary UV coating layer with high adhesion and / or adhesion to express the surface texture (wavy pattern, ring pattern, stripes, marble pattern, etc.) of natural marble or natural wood It is possible. In addition, the surface protective layer composed of the primary UV coating layer and the secondary UV coating layer is superior in abrasion resistance and scratch resistance to the surface protective layer composed of the existing UV coating layer alone.

In the decor sheet of the present invention, preferably, the thickness of the polyolefin-based white or colored film layer is about 50 to about 150 mu m, preferably about 70 to about 100 mu m. When the thickness of the polyolefin-based white or colored film layer is less than 50 탆, there is a problem that the appearance effect is lowered due to the poor printability and hiding power, and when the thickness is more than 150 탆, .

Preferably, the thickness of the primer layers is from about 0.5 to about 2 mu m. If the thickness of the primer layer is less than 0.5 탆, the adhesive force with the upper transparent film layer may be weak. If the thickness exceeds 2 탆, the working speed may be lowered, and adhesion, abrasion resistance and scratch resistance may be deteriorated.

Preferably, the thickness of the printing layer is from about 0.5 to about 2 mu m. When the thickness of the print layer is less than 0.5 占 퐉, various patterns and colors can not be clearly expressed. If the thickness exceeds 2 占 퐉, there is a problem that the operation speed is lowered due to insufficient drying of the print layer.

Preferably, the thickness of the polyolefin-based transparent film layer is about 70 to about 100 mu m. When the thickness of the polyolefin-based transparent film layer is less than 70 占 퐉, there is a problem in that the low-temperature elastic modulus is lowered at the time of molding, and when the thickness is more than 100 占 퐉,

Preferably, the thickness of the primary UV coating layer in the surface protective layer is from about 3 to about 10 microns, preferably from about 5 to about 7 microns, the thickness of the secondary UV coating layer is from about 5 to about 20 microns, About 10 to about 15 microns. When the thickness of the primary UV coating layer is less than 3 mu m, there is a problem that the surface gloss change and the stain resistance of the polyolefin-based transparent film layer are reduced at the time of molding. When the thickness exceeds 10 mu m, There is a problem in that the speed of the surface treatment operation is lowered and a crack is generated in the surface protective layer during molding. If the thickness of the secondary UV coating layer is less than about 5 占 퐉, the surface texture tends to be less expressed. When the thickness of the secondary UV coating layer is more than about 20 占 퐉, There is a possibility.

On the other hand, the decor sheet of the present invention is suitable for thermoforming, and is particularly suitable for vacuum forming. Thermoforming is a method of heating / softening a sheet or film of a thermoplastic resin and forming a shape by vacuum or press. The term thermoforming is used in its broadest sense, including various sheet processing techniques such as vacuum forming, pressure forming, matched mold forming, and combinations thereof.

According to the method of the present invention, the polyolefin-based printing fabric comprising the first primer layer / polyolefin-based white or colored film layer / second primer layer / print layer / third primer layer and the fourth primer layer / polyolefin- Layer is laminated and pressed at 130-150 deg. C, preferably 140-150 deg. C to form a laminate. The fifth primer layer is applied to the polyolefin-based fabric thus bonded, and then the primary UV coating layer is formed over the entire surface of the fifth primer layer.

According to an embodiment of the present invention, the primary UV coating layer preferably has a UV irradiation height of 165 mm / 120 W, a line speed of 70 m / min, a chamber temperature of about 90 캜, a UV dose of 350-400 mJ / Cm < 2 > to form a primary UV coating layer having a thickness of about 3 to 10 mu m. At this time, it is important to control the amount of irradiation to harden the primary UV coating layer to 90% or less, preferably 80% to 90%. That is, under the condition of the present invention, when UV is irradiated at a line speed of 70 m / min at an irradiation dose of 340-400 mJ / cm 2, preferably 340-360 mJ / cm 2, the primary UV coating layer can be obtained in a semi-cured state. However, the semi-cured state can be achieved by adjusting other reaction conditions (intensity, temperature, etc., such as UV, etc.), and the conditions of the present invention are not limited to the irradiation amount.

Next, a secondary UV coating layer is formed on the primary UV coating layer, patterned in a predetermined pattern having a surface texture (wavy pattern or ring pattern, stripe, etc.) such as natural marble or natural wood. The primary UV coating layer and the secondary UV coating layer are then fully cured, thereby increasing the adhesion. That is, under the condition of the present invention, when the UV irradiation is carried out at a line speed of 70 m / min and a dose of 400-450 mJ / cm 2, the secondary UV coating layer can be obtained in a fully cured state. However, the complete curing state can be achieved by adjusting other reaction conditions (such as UV intensity, temperature, etc.), and the condition of the present invention is not limited to the irradiation amount.

As described above, when a general UV coating agent is applied to an adherend, then UV irradiation, and another UV layer formed thereon, there is no adhesion or adhesion between the two layers, so that it is not adhered well. In the present invention, such a problem is solved by combining the components of acrylate and silica in the composition of the primary UV coating layer to form a semi-cured state with a quenching property, leaving the reactor (OH group or the like) Are designed to maintain transparency and thixotropy. The thus obtained decorative sheet according to the present invention has an excellent surface texture and exhibits excellent abrasion resistance and scratch resistance.
