Description

Decorative stainless steel rolled plate with embossed pattern and manufacturing method thereof

The present invention relates to a decorative stainless steel rolled sheet having an embossed pattern and a method of manufacturing the decorative stainless steel rolled sheet having an embossed pattern, and more particularly to a method comprising ion plating such as nano ceramic coating or PVD (physical vapor deposition). A surface treated continuous thin stainless steel sheet and a decorative stainless steel rolled sheet having an embossed pattern embossed together with an anti-adhesive film having a non-woven layer bonded to one side of the thin stainless steel sheet by a hot melt adhesive layer and the embossed pattern is produced The method of decorating stainless steel rolled sheets.

Typical decorative sheets are used for the surface treatment of various products to protect the product and impart a variety of colors, patterns and textures.

For example, decorative sheets are widely used for interior surface treatment of buildings, elevators, automobiles, ships, and airplanes or for surface treatment of various furniture or electronic products.

Depending on the end use, the types of decorative sheets are covered, wrapped, film and edge. Covered decorative sheets are generally used for flat tops of furniture, MDF (medium density fiberboard) or particle board, while wrapped decorative sheets are used for parts requiring a bending process such as narrow frames or molds.

Further, the film-type decorative sheet is applied to a typical furniture or door having a curved portion, and the edge-type decorative sheet is applied to the corner of the furniture or the side of the table or the upper plate thereof. Recently, iron-plate type decorative sheets have been applied to the outer surfaces of electronic products and other iron sheets.

Since the conventional decorative sheet is mainly made of synthetic resin, surface strength and wear resistance are low and undesirably caused scratches. Further, even when these conventional decorative sheets are subjected to a refractory surface treatment, they are low in heat resistance and fire resistance and poor in burn resistance.

In order to impart a metal texture to a decorative sheet, a metal foil paper has recently been attempted to be bonded to the bottom or top surface of the substrate.

Although the method of bonding metal foil paper can impart a metal texture to the decorative sheet, it is still problematic because it is difficult to form various designs including text and graphics in the form of a film on the metal foil paper, and further, since the flexibility may be lowered and wrinkles may occur. This makes it difficult to produce decorative sheets for calendered sheets and their packaging and handling.

Further, when the decorative sheet is bonded to the target, it may fall off because it cannot be very flexible and wrinkled.

In particular, since the decorative sheet is not very flexible and it is difficult to apply it to the concave portion, the protruding portion, and the curved portion because of its wrinkles.

Korean Patent No. 0896622 discloses a metal texture decorative sheet and a method of manufacturing the metal texture decorative sheet. In particular, the metal texture decorative sheet comprises a substrate, a metal texture layer formed on the substrate, a printed layer formed on the metal texture layer, and a transparent film formed on the printed layer, including a metal texture of text and graphics. The layer is formed on the substrate by a printing metal ink comprising metal particles comprising a dispersion having a metal particle having a size of 1 to 100 nm, a binder, a solvent, and a dispersing agent. Therefore, the metal ink comprises: 5.0 to 50.0 parts by weight of metal particles, 10.0 to 60.0 parts by weight of a binder, 10.0 to 40.0 parts by weight of a solvent, 0.05 to 5.0 parts by weight of a dispersing agent based on the total weight of the metal ink, wherein the metal ink comprises: The agent may be a C4 to C12 alkyl alkylamine, a carboxyguanamine, an aminocarboxylic acid or a sodium citrate. In addition, a method for manufacturing a metal texture decorative sheet comprises forming a metal texture layer on a substrate to obtain a semi-finished product, attaching a transparent film having a printing layer on the semi-finished product, and conveying the semi-finished product through an embossing roll to form a desired thin plate by hot pressing, wherein the metal The texture layer comprises text or graphics formed on the substrate by a printed metallic ink comprising metal particles comprising a dispersion of metal particles having a size of from 1 to 100 nm, a binder, a solvent and a dispersing agent. Therefore, the metal ink may include: 5.0 to 50.0 parts by weight of metal particles, 10.0 to 60.0 parts by weight of a binder, 10.0 to 40.0 parts by weight of a solvent, and 0.05 to 5.0 parts by weight of a dispersing agent based on the total weight of the metal ink, wherein The dispersing agent may be a C4 to C12 alkyl alkylamine, a carboxyguanamine, an aminocarboxylic acid or a sodium citrate.

The decorative sheet thus produced is advantageous because the metal texture layer is formed by printing with a metallic ink, thus embodying the design of various metal textures and ensuring flexibility compared to the form of the metal foil. However, such a decorative sheet is also disadvantageous because the transparent film constituting the uppermost portion of the decorative sheet is made of synthetic resin, so that the abrasion resistance is low, and because of low heat resistance and fire resistance, the decorative sheet is not easily burned and is processed therein. It may pollute the environment.

However, the decorative sheet is manufactured by using a unit for manufacturing a semi-finished product including a metal texture layer printed by a metal ink containing metal powder uniformly dispersed therein, a unit for forming a printed layer on the transparent film, and a unit. Bonding a transparent film to a semi-finished product to produce a desired sheet of the unit undesirably makes controlling the manufacturing process difficult and causes problems such as increased manufacturing costs and low throughput.

Furthermore, since the metal powder included in the metallic ink causes the metallic texture to appear, the texture and inherent properties unique to the metal cannot naturally manifest itself, degrading the quality of the product undesirably.

The inventors of the prior art have worked hard to solve the problems encountered in the art and have thus found that after various surface processes, light weight and excellent corrosion resistance, wear resistance, heat resistance, fire resistance, workability and Durable thin stainless steel sheets are ideal for use as decorative metal sheets.

However, typical thin stainless steel sheets have a constant cold metal texture and are smooth and unsuitable for use as a decorative surface treatment.

Therefore, a thin stainless steel plate as a decorative metal sheet must have a rough surface treatment and various colors and thicknesses between 0.05 and 0.15 mm.

Generally, a thin stainless steel sheet having a thickness of between 0.8 and 1.5 mm and treated mainly by a rough surface using a physical process such as a wire brush, a sandblasting or a vibrating brush is useful. However, in the case where a thin stainless steel sheet suitable for use as a decorative metal sheet and having a thickness of 0.05 to 0.15 mm is subjected to a rough surface treatment using the above physical process, the surface thereof may be undesirably destroyed.

In addition, when the surface of a smooth thin stainless steel plate is subjected to an inorganic coating using nano ceramics (SiO ₂ , SnO _{2 ,} etc.) or an ion plating film of titanium (Ti), chromium (Cr), zirconium (Zr), or PVD, Its surface roughness may be reduced and various colors are obtained.

In addition, the nano ceramic coating is a coating process using a nano material having a size of 10 to 20 nm, thereby resulting in a lower manufacturing cost than using PVD, and can be obtained by using an organic coating and a nano inorganic coating. Wide range of colors.

On the other hand, when ion plating is performed using PVD, materials such as Ti, Cr, Zr are evaporated in a vacuum and the particles thereof adhere to the surface of the stainless steel plate, so that superior quality is obtained compared with the wet process but is not expected This leads to higher manufacturing costs. The color may be gold, brown, black, etc., depending on the type of gas injected during coating.

A nano-ceramic coating that results in a coating thickness of 20 μm or less or a PVD inorganic coating that results in a coating thickness of 0.5 to 1.0 μm exhibits various products almost after treatment such as bending or embossing after coating. The surface finish requires the required color and surface roughness.

According to the test of the present inventors, although a thin stainless steel plate having a thickness of 0.05 to 0.15 mm and passing through a nano ceramic coating or a PVD ion plating is not cushioned, a positive pattern roller and a negative pattern roller may be used and correspond to the pattern. The embossing roll is processed to have an embossed pattern, which is difficult to display a well-defined clear pattern, and the use of an embossing roll composed of positive and negative pattern rolls makes the production difficult, increases the manufacturing cost, and causes a large amount of friction, which is undesirable. The ground led to a short service period.

In addition, even when a thin stainless steel plate is embossed with an embossed pattern, its resistance to elongation, shape stability, flexibility, and wrinkle resistance is poor, and it is difficult to obtain a smooth cut surface when cut, and thus it is difficult to package, handle, and put up.

A thin stainless steel plate having a thickness of 0.05 to 0.15 mm is fabricated into a decorative sheet which has been subjected to a nano ceramic coating or a PVD ion plating, and the concentrated and thorough research has led to the discovery of the smooth roll of the present invention, which can transmit ductility resistance. , trait stability, flexibility, crease resistance and cushioning properties for thin stainless steel plates and easy processing, reducing processing costs and producing a small amount of friction, thus having a long service life, so embossing compared to the use of conventional negative pattern rolls The pattern is finer, more beautiful, and more tidy, and the resulting sheet can be widely used for overlapping, crimping, diaphragm or edge type surface treatments without being limited by various target surface conditions, thus not only satisfying the physical requirements of the decorative sheet. And chemical properties, but also meet the aesthetic appearance, construction and economic efficiency.

Accordingly, it is an object of the present invention to provide a decorative stainless steel rolled sheet having an embossed pattern comprising a thin stainless steel sheet surface treated with, for example, a nano ceramic coating or a PVD (physical vapor deposition) ion plating film, and a separate anti-adhesive film or The hot melt adhesive layer sequentially adheres to the non-woven layer and the anti-adhesion film on one side of the thin stainless steel plate, and is embossed together and adheres to each other with the embossed pattern, thereby exhibiting excellent ductility, shape stability, flexibility and Wrinkle resistance, and a method of making a decorative stainless steel rolled sheet having an embossed pattern.

Hereinafter, the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the decorative stainless steel rolled plate having an embossed pattern according to the present invention is disposed as follows, and the anti-adhesive film 14 or the non-woven layer 16 and the anti-adhesive film 14 are sequentially bonded to the ceramic via the hot-melt adhesive layer 12, for example, by a nano ceramic. The back side of the coated or PVD ion coated surface treated thin stainless steel sheet 10, wherein all of the thin stainless steel sheet 10, the hot melt adhesive layer 12 and the release film 14 or all of the thin stainless steel sheets 10, the hot melt adhesive layer 12, the non-woven fabric The layer 16 and the anti-adhesive film 14 are embossed together, whereby the thin stainless steel plate 10, the hot melt adhesive layer 12 and the anti-adhesive film 14 or the thin stainless steel plate 10, the hot melt adhesive layer 12, the non-woven layer 16 and the anti-adhesive film 14 are embossed The patterns 18 are bonded to each other.

In the present invention, the thin stainless steel sheet 10 may have a thickness of 0.05 to 0.15 mm, and if the thickness is less than 0.05 mm, the sheet is difficult to manufacture and expensive. Conversely, if the thickness exceeds 0.15 mm, the strength of the sheet increases, making it difficult to perform embossing and it is impossible to obtain a clearer pattern.

The hot melt adhesive layer 12 may have a thickness of 0.05 to 0.12 mm. If the thickness is less than 0.05 mm, the adhesive force will be weakened, and the cushioning effect applied to the thin stainless steel plate 10 at the time of embossing is weak. Conversely, if the thickness exceeds 0.12 mm, when the thin stainless steel sheet 10 and the release film 14 are bonded together, the adhesive may overflow the edge of the rolled sheet, undesirably lowering the product quality.

The thickness of the nonwoven layer 16 may be 0.05 to 0.10 mm. If the thickness is less than 0.05 mm, the cushioning effect applied to the thin stainless steel plate 10 at the time of embossing is weak. On the contrary, if the thickness thereof exceeds 0.1 mm, the adhesive of the hot melt adhesive layer 12 can be excessively absorbed by the nonwoven fabric layer, undesirably weakening the adhesive force of the hot melt adhesive layer 12.

The release film 14 has a release preventing effect and a flexible polyethylene film or polypropylene film, and may have a thickness of 0.05 to 0.10 mm depending on the depth of the embossed pattern 18, that is, whether the pattern is shallow or deep. If the thickness is less than 0.05 mm, the film is easily broken during embossing and handling, making it impossible to effectively protect the product, and the cushioning effect applied to the thin stainless steel plate 10 at the time of embossing becomes weak. Conversely, if the thickness exceeds 0.10 mm, there is no benefit in terms of cost.

The depth of the embossed pattern 18 can be set to 50 to 200 μm. If the depth is less than 50 μm, a clear pattern cannot be obtained. Conversely, if the thickness exceeds 200 μm, the thin stainless steel plate 10 will be broken or deformed.

In the present invention, when the embossed hot melt adhesive layer 12 is adhered to the thin stainless steel plate 10 and the release film 14 or the non-woven layer 16 and the release film 14 on the back side of the thin stainless steel plate 10, it is preferably in the hot melt adhesive layer 12. The surface of the thin stainless steel sheet 10 is extruded before the adhesive is fully cured to form an embossed pattern 18. The reason is that the adhesive portion between the thin stainless steel plate 10 and the hot melt adhesive layer 12, the non-woven fabric layer 16 into which the adhesive of the hot melt adhesive layer 12 penetrates, and the adhesive portion between the non-woven fabric layer 16 and the release film 14 are completely cured. Before, the hot melt adhesive layer 12 and the release film 14 or the nonwoven fabric layer 16 and the release film 14 can sufficiently provide the buffering effect required for embossing, so that an embossing pattern 18 can be obtained by performing an embossing.

Preferably, the hot melt adhesive layer 12 is made of a wet solid hot melt adhesive which is cured by isocyanic acid stored in the adhesive, even in air or body, as compared with a typical hot melt adhesive. After the water is cooled, the molecular weight increase thus causes high heat resistance to the body, and has a lower initial adhesion before isocyanic acid and moisture cross-linking. This is because when the wet-solid hot-melt adhesive is used to adhere the non-woven fabric layer 16 and the anti-adhesive film 14 to the back surface of the thin stainless steel plate 10, the initial adhesive force is lower than that of the general hot-melt adhesive, but it is required for embossing. The cushioning effect, that is, the elastic restoring force may increase, so that a clearer embossed pattern can be formed immediately. Further, since the solidification is caused by the cross-linking between the moisture present in the air in the non-woven fabric layer 16 and the isocyanic acid which penetrates the wet-laid hot-melt adhesive of the nonwoven fabric layer 16, the thin stainless steel sheet 10 and the non-woven fabric layer 16 will Bonding more closely together results in a decorative stainless steel rolled sheet that has excellent ductility, shape stability, flexibility, and cushioning, and it is difficult to achieve all of the above effects using only a thin stainless steel sheet 10.

In the present invention, when the non-woven fabric layer 16 infiltrated with the hot melt adhesive is used, less hot melt adhesive can be used than simply applying the hot melt adhesive to the thin stainless steel sheet 10, and the adhesive will be uniformly dispersed. On the thin stainless steel plate 10, the production cost is reduced and the bonding strength is enhanced.

The stainless steel rolled plate with the embossed pattern of the present invention is adhered to an object by using an adhesive tape after the release film 14 is removed. In order to make the rolled sheet adhere to the object without using an adhesive, as shown in FIG. 2, the double-sided tape 42 having the release paper 41 formed only on one side thereof may be adhered to the hot melt adhesive layer 12 after the release film 14 is peeled off. .

Further, in order to use the stainless steel rolled sheet having the embossed pattern according to the present invention for the inner surface treatment having higher fire resistance and durability, as shown in Fig. 3, as the release preventing film 14 is torn off, an additional adhesive layer is provided. 44 is formed on the cured hot melt adhesive layer 12, and a thin plate member 46 comprising an aluminum plate or a plated steel plate having a thickness of 0.2 to 1.2 mm is adhered to the additional adhesive layer 44.

If the thickness of the thin plate member 46 is less than 0.2 mm, fire resistance and durability may become insufficient. Conversely, if the thickness exceeds 1.2 mm, the flexibility becomes weak.

In the decorative stainless steel rolled sheet having the embossed pattern of the present invention, when the embossed pattern 18 is formed on the surface of the embossed thin stainless steel sheet 10, all the thin stainless steel sheets 10, the hot melt adhesive layer 12, the non-woven layer 16, and the use time The contact faces of the release film 14 to be peeled off therefrom may be bonded to the embossed pattern, thereby increasing the upper bonding regions and thereby enhancing the bonding strength so that they are not thermally contracted or thermally expanded or bent. The external force of the load is peeled off from each other, so that their surface strength is enhanced. Therefore, excellent heat resistance, fire resistance, ductility, shape stability, flexibility, and wrinkle resistance can be obtained, thereby satisfying not only the physical and chemical properties required for the decorative sheet but also the aesthetic appearance and construction property. And economic efficiency.

Processing, such as nanoceramic coating or PVD ion coating, is fed between the first feed rolls 22, using the adhesive feed rolls 24 and the first feed rolls 22, delivered by the first feed rolls 22. One side of the thin stainless steel plate 10 is coated with a hot melt adhesive, so that a hot melt adhesive layer 12 is formed on one side of the thin stainless steel plate 10, and the roll 26 is taken up from the release film to a thickness of 0.05 to 0.10 mm and made of polyethylene or polypropylene. The film-preventing film 14 is unwound and fed between the second feed rolls 28, thereby being bonded to the hot melt adhesive layer 12 formed on one side of the thin stainless steel plate 10, using the positive pattern roll 30 and the smooth roll 32. An embossing roll 34 is formed to emboss the thin stainless steel sheet 10 and the release film 14 adhered thereto by the hot melt adhesive layer 12, thereby transferring the embossed pattern 18 and winding the final product in the form of a rolled sheet to the take-up roll 36. on.

Therefore, the thickness of the hot melt adhesive layer 12 is 0.05 to 0.12 mm, and the depth of the embossed pattern 18 is 50 to 200 μm, and the embossing is performed before the hot melt adhesive layer 12 is completely cured.

Example 2

And different colors. Moreover, the decorative stainless steel rolled sheet can be mass-produced at a lower cost and uniform quality. The decorative stainless steel rolled sheet is obtained by forming a hot melt adhesive layer 12 on one side of the continuously fed thin stainless steel sheet 10; and adhering the anti-mud film for continuous feeding. 14 or sequentially feeding the non-woven layer 16 of the adhesive layer and the anti-adhesion film, embossing to form the embossed pattern 18; and winding the final product in the form of a rolled plate, so that mass production can be performed at low cost and uniform quality.

In addition, the decorative stainless steel rolled sheet of the present invention not only satisfies the physical and chemical properties required for the surface treatment of various products, but also satisfies the aesthetic appearance, construction and economic efficiency.

In addition, the decorative stainless steel rolled plate of the present invention is used in such a manner that the anti-adhesive film 14 is peeled off from the adhesive film and adhered to the object by an adhesive, and may be adhered to the adhesive depending on the environment and conditions of use. object. In particular, as shown in Fig. 6, such a rolled sheet can be bonded to the cured film by the double-sided tape 42 having the release paper 41 formed on one side after being peeled off from the rolled sheets of Examples 1 and 2. Manufactured from the hot melt adhesive layer 12.

Further, as shown in Fig. 7, in order to treat the rolled sheet of the present invention as an inner surface treatment requiring excellent fire resistance and durability, the rolled sheet can form an additional adhesive layer on the cured hot melt adhesive layer 12. 44. A thin plate member 46 composed of an aluminum plate or a plated steel plate having a thickness of 0.2 to 1.2 mm is bonded to the additional adhesive layer 44, and the final product is manufactured after the release film 14 is peeled off from the rolled sheets of Examples 1 and 2. .
