The present invention relates to a method for manufacturing an embossed wall paper, and in particular, an adhesive is formed in a closed space formed by the embossed pattern between an embossed pattern formed and a front surface printed on the surface and a back sheet bonded to the front surface. In addition to being filled, the front and rear papers can be attached to each other without damaging the embossed pattern, thereby improving the bonding strength of the front and back papers, and the shape of the embossed pattern can be retained in the manufacturing process and the papering process as well as after the papering. It relates to an embossed wallpaper manufacturing method.

Looking at the manufacturing process of the embossed wallpaper, by applying an adhesive to one of the two sheets (front / back) of the basis weight of about 70g ~ 100g bonded to each other to make a bond paper, of the bond paper on the surface of the front paper It is common to form an embossed pattern by printing a color and a pattern while passing the bonding paper between the embossing roller and the support roller having the pattern forming irregularities on the outer circumferential surface thereof. In addition, printing the color and pattern on the surface of the front paper first, and then applying an adhesive to either of the front / back paper to bond the front / back paper to each other to form a bonding paper, as described above, a number of methods for forming an embossed pattern is also employed.

The structure of the embossed wallpaper produced by the above method is shown in FIG. In the embossed wallpaper 100, since the front and back papers 110 and 120 are joined together as a whole, the bonding strength of the front and back papers 110 and 120 is excellent. However, when the paper embossed wallpaper 100 is pasted on the back of the backing paper 120, the paper, the embossed pattern 112 to the back surface of the back paper 120 by the embossed pattern 112, so the rear Edge 120 is not attached to the wall as a whole, only the portion except the groove 122 is attached. Therefore, the adhesive force of the embossed wallpaper 100 to the wall surface is inevitably lowered, and there is a possibility that the embossed wallpaper 100 is lifted from the wall surface. In addition, in the papering process, the embossed wallpaper 100 is rubbed with a tool such as a towel or a broom to the wall surface so that the embossed wallpaper 100 is attached well to the wall surface. ) Is pressed toward the grooves 122 to maintain its shape or damage occurs, so the three-dimensional feeling of the embossed pattern 112 is reduced after drying, so that the wall surface cannot be beautifully decorated. In addition, since the grooves are caught in the grooves 122, there is a problem of providing a cause of mold occurrence.

In order to solve the problems as described above, a pattern is formed by embossing only on the front side paper, and various techniques have been proposed for manufacturing embossed wallpaper by attaching the back side paper which is not embossed to the front side paper, which is representative of domestic patent announcement. And those disclosed in US Pat. No. 1991-3890.

An example of an embossed wallpaper produced by this technique is shown in FIG. 6.

In the embossed wallpaper 200 according to the prior art, the embossed pattern 212 is supported by the iron roller and the sliding roller without being damaged by the uneven pattern of the iron roller when the decorative paper 210 and the reinforcement paper 220 are joined. In the process of joining the decorative paper 210 and the reinforcement paper 220 in the bonding process can be eliminated, the adhesive force to the wall surface of the embossed wallpaper 200 in that the back surface of the reinforcement paper 220 is completely attached to the wall during the delivery This has the advantage of being improved. In this case, however, unlike the embossed wallpaper 100 of FIG. 5, the decorative paper 210 and the reinforcement paper 220 are not completely bonded, and only the portions except the embossed pattern 212 are bonded to the decorative paper 210 and the reinforcement paper ( 220) The bonding quality is low. For this reason, the decorative paper 210 is separated from the reinforcing paper 220 around the closed space 214 formed between the decorative paper 210 and the reinforcing paper 220 by the embossed pattern 212, and the decorative paper 210 is separated. There is a risk of being lifted, and the phenomenon of embossing pattern 212 being pressed and damaged by the closed space portion 214 after the process of papering the manufactured embossed wallpaper 200 or still cannot be prevented.

The present invention has been made in consideration of the above-described conventional problems, and the adhesive is formed in the closed space formed by the embossed pattern between the front surface paper on which the embossed pattern is formed and the front surface printed on the surface and the back sheet bonded to the front paper. And the front and back papers are attached to each other without damaging the embossed pattern, thereby improving the bonding strength of the front and back papers, and retain the shape of the embossed pattern as it is in the manufacturing process and the papering process as well as after the papering.

As described above, it is preferable that the adhesive A be foamed upon drying, when the depth of the closed space G is 80 μm or more.

<Joining process>

The front paper S1 having the embossed pattern F and the back paper S2 coated with the adhesive A have a space between the embossing roller 51 and the pressure roller 54 constituting the embossing joining means 50 together. By passing through, it is formed of bonding paper S3. Of course, the front and rear paper (S1, S2) must pass between the embossed roller 51 and the pressure roller 54 in a state where the adhesive coated surface of the back paper (S2) is in contact with the back surface of the front paper (S1). When the front and rear papers S1 and S2 pass between the embossed roller 51 and the pressure roller 54, the uneven pattern 52 of the embossed roller 51 receives a strong pressure by the pressure roller 54. It adheres to the valley part of the embossed pattern F of the front paper S1 suitably. Therefore, the part of the front side paper S1 except for the embossed pattern F can be made in a good state of being bonded to the back side paper S2, so that the poor bonding of the bonding paper S3 and the embossing pattern in the bonding process ( No damage to the embossed pattern F occurs because F) is not pressed.

In the joining process, the rotational angular velocity of the pressure roller 54 is slightly larger than that of the embossed roller 51 or the diameter of the pressure roller 54 is larger than the diameter of the embossed roller 51 to increase the radial speed. Since the adhesion between S1) and the embossed roller 51 becomes greater, the bonding quality can be further improved. In addition, when the adhesion is improved in this way, the excess amount of the adhesive A applied to the back paper S2 is toward the closed space G formed between the front and back papers S1 and S2 by the embossed pattern F. There is also an advantage that the adhesive A to the closed space portion G can be filled in a good state.

<Drying process>

Bonding paper (S3) is formed by bonding the front / back paper (S1, S2) is dried by passing through the drying means 60 along the guide rollers (R), while the adhesive (A) is cured in this drying process The adhesive A filled in the closed space G is foamed so that the closed space G is completely filled by the adhesive A. FIG.

<Winding process>

The embossed wallpaper S, which is completed by drying of the bonding paper S3, is wound and cut in roll form by a length normalized by the winding means 70, and then packaged and shipped.

Meanwhile, according to the present invention, the adhesive may be filled in the closed space G even by excessively applying the adhesive A which does not contain a foaming agent in the adhesive applying process among the above processes. It can be mainly applied when the depth of the closed space (G) is 80㎛ or less. That is, when the closed space G is formed to a depth of 80 μm or less, when the adhesive is excessively applied to the backing paper with a coating thickness of 20 to 50 μm so that the adhesive is filled in the closed space, the adhesive ( Since A) is pushed into the closed space portion G and the closed space portion G is filled with the adhesive A, the adhesive A is cured during the drying process so that the form of the embossed pattern F can be retained as it is. will be. Of course, in this case as well, it is preferable to use an acrylic emulsion-type binder as a main agent to prevent elongation, deformation, etc. of the embossed wallpaper S.

<Example>

Next, the quality of the embossed wallpaper manufactured according to the manufacturing method of the present invention and the embossed wallpaper manufactured through another manufacturing method were compared.

<Example 1>

20 to 80 wt% of calcium carbonate or talc with respect to the whole adhesive, and 3 wt% or more of general synthetic resin organic foaming agent or inorganic foaming agent to an acrylic emulsion type binder polymerized based on methyl methacrylate as a monomer system Are mixed to form an adhesive, and considering the size of the closed space portion G formed by the embossing pattern F, the adhesive is stepwise on one surface of the backing paper S2 with a thickness in the range of 20 to 100 μm. After application, the backing paper S2 and the embossed front paper S1 were bonded by embossing bonding means to make a bonding paper S3. Then, the bonded paper S3 was passed through a heat-drying chamber 61 at 180 to 220 ° C. to dry, thereby producing an embossed wallpaper.

As a result of inspecting the quality of the embossed wallpaper, a slight distortion was found on the surface due to the high foaming temperature of the general organic foaming agent or inorganic foaming agent for general synthetic resin, but the blending ratio of the binder, calcium carbonate or talc was 50 In the case of 50: the embossed wallpaper itself and the elasticity of the foamed adhesive hardened and filled in the closed space (G) was good, it can be seen that the embossed pattern (F) is elastically retained.

<Example 2>

Except the foaming agent was replaced with a capsule foaming agent having a low temperature in the foaming temperature range of 80 ~ 120 ℃ and the capsule formed of an acrylic resin in the same manner as in Example 1 to make a bonding paper (S3), this bonding paper (S3) An embossed wallpaper was produced by passing through a heat drying chamber 61 at 120 ° C.

As a result of inspecting the quality of the embossed wallpaper, it was found that not only the flexibility of the embossed wallpaper itself was good but also that the deformation did not occur.

<Example 3>

Comparative Example 2

As an adhesive, a polysol (E.V.A), which is a general adhesive, was used, and the polysol (E.V.A) was applied to one surface of the backing paper S2 with a thickness of 20 µm to prepare embossed wallpaper through the same process as in the examples.

As a result of inspecting the quality of the embossed wallpaper, the foaming agent is not added to the adhesive, and the coating thickness thereof is small, so that the adhesive is not filled in the closed space G, and thus the embossing pattern (F) in the manufacturing process as well as in the papering process. Deformation and damage were found.

Comparative Example 3

Embossing was carried out in the same manner as in Comparative Example 2 except that polysol (EVA), which is a general adhesive, was used as an adhesive, and the polysol (EVA) was applied stepwise to one surface of the backing paper S2 at a thickness of 20 to 100 µm. The wallpaper was prepared.

As a result of inspecting the quality of the embossed wallpaper, the phenomenon in which the front and back papers (S1, S2) are simultaneously stretched due to more adhesive moisture in the bonding process, the spread of the embossed pattern (F) and the surface of the embossed wallpaper Flexural paper was found to be deformed.

<Comparative Example 4>

An acrylic emulsion-type binder was used as an adhesive, and the adhesive was applied stepwise to one surface of the backing paper S2 with a thickness of 20 to 100 μm to prepare an embossed wallpaper through the same process as in Comparative Example 2.

As a result of inspecting the quality of the embossed wallpaper, the elongation and bending deformation were not found very much, but the deformation of the embossed pattern F or the flexibility of the embossed pattern F was found depending on the adhesive coating thickness.
