FIG. 1 is a sectional view of one embodiment of a melamine baking sheet according to the present invention, FIG. 3 is a cross-sectional view of a melamine baking sheet according to the first embodiment of the present invention, Sectional view of another embodiment of the veneer.

Referring to FIGS. 1 to 3, in the method for producing a melamine faced sheet of the present invention, a transparent or semitransparent overlay paper is impregnated with a melamine resin to form overlay layers 9a and 9b, (10a, 10b) and a lower layer (10a, 10b) by impregnating the kraft paper with phenol resin to form lower layers (11a, 11b) The step of forming the overlay layers 9a and 9b by lamination and molding at a high temperature and a high pressure is the same as the conventional manufacturing method and the step of forming the overlay layers 9a and 9b is optional.

Here, in the manufacturing method of the present invention, after the overlay paper or the embossed paper is impregnated with the melamine resin in the step of forming the overlay layers 9a and 9b or the step of forming the upper layers 10a and 10b, 12b, 13 on the upper layer or the overlay layer by printing ink on the emboss rolls 6, 7 by coating the ink 3, 4, 5.

Referring to FIG. 1, the step of forming a magnetic pattern layer on the upper layer is described. In order to form an upper layer, the shape sheet 1 is impregnated with a melamine resin as in the prior art, The ink 3, 4, 5 is coated and then printed with the embossing rolls 6, 7 to form a magnetic pattern layer, followed by drying.

Here, the amount of the melamine resin impregnated in the upper layer 1b is 70300 parts by weight relative to the shape paper, the unit weight of the paper is 10-300 g / m ^2, preferably 10-100 g / m ² , The coating amount of the ink (3, 4, 5) is preferably 160 g / m ² before the impregnated resin is dried because the ink penetrates into the resin in the subsequent drying step, Inlaid or inlaid, so that a more unique appearance can be expected.

The ink (3, 4, 5) is produced so as to exhibit a beautiful appearance effect. As the material thereof, a pigment for imparting a general pigment or a pearl effect, an oil or water ink, (Pearl, chip) or the like is used as a raw material, it is possible to expect a more brilliant appearance effect. The particle size of these pigments, paints and chips is preferably 100 μm to 1000 μm in diameter And they are mixed with melamine resin at a ratio of 10: 110: 8. Various colors may be used depending on the number of the ink tanks 2, and a single color may be used as needed. In addition, the ink tank 2 for storing ink can be used in almost all types of dropping and coating apparatuses such as a trapezoidal tank, a roll coater and a nozzle shape as shown in the figure.

As described above, the step of printing with the embossing rolls 6 and 7 can be selectively added, which is performed in order to impart a unique and various pattern effect to the pattern layer of the mother board, Similarly, the convex roll 6 and the concave roll 7 may be alternately used, or any one of them may be selectively used. Any material such as rubber, urethane, or steel may be used as the material of the embossing roll.

In the above, although it is exemplified that the imprint layer is formed on the upper layer, the same process can be applied to the overlay layer.

That is, in order to form an overlay layer, the overlay paper is impregnated with melanin resin, the ink is coated before the impregnated resin is dried, printed with an embossing roll, and dried to form a pattern layer on the overlay layer. The overlay paper preferably has a unit weight of 10,300 g / m ^2, preferably 10 000 g / m ^2, and the amount of the melamine resin impregnated into the overlay paper is preferably 50300 parts by weight. The coating amount of the ink (3, 4, 5) Is preferably 160 g / m ² .

When there is a difference in the step of forming the magnetic pattern layer on the upper layer and the overlay layer, in the case of forming the magnetic pattern layer on the overlay layer, even if a multi-pattern layer is formed on either or both surfaces of the overlay layer, Since the external effect for the purpose of forming the pattern layer can be expected, these processes can be selectively performed. On the other hand, in the case of the upper layer, when the internal pattern layer is formed on the back surface of the upper layer, It is preferable to form a pattern layer only on the surface.

In FIG. 1, reference numeral 8 denotes a tension adjusting roll.

FIG. 2 is a cross-sectional view of a melamine facer according to an embodiment of the present invention. The basic laminate structure is composed of three layers of a lower layer 11a, an upper layer 10a and an overlay layer 9a from below, The pattern layers 12a and 12b are further formed on the front and back surfaces of the overlay layer 9a, respectively.

Here, the lower layer 11a and the upper layer 10a are layers in which the lower layer 11a is impregnated with phenolic resin, and the upper layer 10a is a layer impregnated with a melamine resin.

The overlay layer 9a is a layer formed by impregnating a transparent or translucent overlay paper with melamine resin. The overlay layer 9a serves to increase abrasion resistance and protect the surface of the overlay layer 9a. In the present invention, The ink-pattern layers 12a and 12b coated with the above-described ink are further formed on the front and rear surfaces of the first and second ink-repellent layers 9a and 12b, respectively, As shown in the figure, emboss rolls may be formed with concave or convex mark patterns to produce stereoscopic aesthetics.

In FIG. 2, the boundary line between the overlay layer 9a and the pattern layers 12a and 12b is merely divided for the convenience of explanation. Actually, the ink penetrates continuously for a long time to constitute the overlay layer, , The boundaries of the two layers are not clear on the second side.

2 shows a case where a multi-patterned magnetic layer is formed on both the front and back surfaces of the overlay layer, however, a magnetic pattern layer may be formed on either the front side or the back side if necessary.

FIG. 3 is a sectional view of a melamine facer according to another embodiment of the present invention. As shown in FIG. 2, the basic lamination structure of the melamine facer comprises three layers of a lower layer 11b, an upper layer 10b and an overlay layer 9b On the upper layer 10b, a magnetic pattern layer 13 is formed for exerting a special appearance effect. In this case, when the trailing edge layer 13 is disposed below the upper layer 10b, no appearance effect can be obtained, so that the trailing edge layer is formed only on the upper side.

In addition, the shape and the amount of the overlay paper used in the second and third drawings, the components of the ink, the composition, and the like are as described above.

As described in the above embodiments, the melamine faced sheet according to the present invention is formed by coating an ink capable of exhibiting a unique appearance effect on one of the upper layer and the overlay layer, and forming the embossed pattern It is possible to give not only a planar decoration effect by a shape like the conventional one but also various decorating effects by the pattern of the national station, so that a more luxurious surface decoration effect can be exerted.

Accordingly, the melamine baked sheet of the present invention can satisfy the desire of consumers who demand a more luxurious and beautiful appearance as the living standard is improved.
