Description

Composition of long-floor decorative material matching printing and embossing pattern and its manufacturing method {PVC Flooring Matched Print and Embossed Pattern}

The present invention provides a three-dimensional appearance effect by synchronizing a printed pattern and an embossed pattern on a long vinyl floor decoration material, thereby providing a surface layer with a floor decoration material having a sense of realism, depth and quality of natural (wood, stone, fabric, etc.). By matching the embossed concave-convex pattern with the important pattern of the printing layer and transferring the pearl ink, the depth of double printing effect, the softness of pearl, the three-dimensional and realism of the embossed pattern matching the printed pattern It is about the three-dimensional exterior floor decoration material which can feel a sense of quality.

In general, the long floor decorative material used is not only monotonous in appearance but also limited in expressing a three-dimensional appearance by providing an amorphous emboss while forming a vinyl chloride transparent layer after printing.

As a conventional technique for escaping such monotony and giving a three-dimensional feeling, the three-dimensional pattern method described in Patent Publication No. 93-23190 has a technique of expressing a three-dimensional appearance by incorporating a blowing agent in the printed layer to protrude the printed pattern. For example, the flooring material using this technique is to impart a printed pattern to a printed layer containing a foaming agent, using an ink in which a foaming accelerator or a foaming inhibitor is added, and passing the printed layer having a printed pattern through the foaming oven. Only the printing part containing the foaming accelerator or the foaming inhibitor is given a three-dimensional appearance effect while promoting or inhibiting the foaming.

However, the flooring material has a disadvantage that it is difficult to use in places where walking is frequent because the printed layer of the upper part of the product is made of foam, so that the surface layer is hard to be stamped, scratched or pressed, and the embossed pattern of round shape is not delicate embossed shape. Is obtained, there is a limit in expressing the depth and delicate three-dimensional appearance.

Another conventional technique is a utility model publication. Publication No. 95-9019, and the flooring material described in this publication, gives an uneven pattern to the printed layer with embossing, fills the ink with the uneven embossed pattern, and then prints a predetermined printed pattern thereon, and the upper transparent layer. By forming a three-dimensional appearance effect.

However, the flooring material does not match the printed pattern and the embossed pattern, because the ink and the printed pattern is directly stacked on the embossed pattern, there is a lack of three-dimensional and realism. In addition, the ink is applied to the entire surface of the embossed patterned printing layer, filling only the ink and removing the remaining ink, at this time, the ink removal process is difficult and the work efficiency is inferior.

Also, in order to express the three-dimensional appearance effect in the piece type flooring material (e.g. tiles) rather than the long floor decorative material as a conventional product, in order to give an embossed pattern that matches the printing pattern of the specific part, it matches the printed pattern of the specific part. The three-dimensional effect was provided using the metal plate which the uneven embossing which carved is. However, this method can be produced only in Piece Type products by applying flat embossing, and cannot be applied to long vinyl flooring which is applied to continuous process. Therefore, the productivity is lowered, the cost is increased, and the construction is more difficult than the long product when constructing the product, which requires much labor cost and time.

In order to solve this problem and to give a delicate three-dimensional impression, an attempt was made to match the printed pattern and the embossed pattern with the uneven embossing roll on the long vinyl flooring material, but the heat and tension of the embossed pattern As the printed pattern increased, it was impossible to align the printed pattern with the embossed pattern.

In the present invention, in order to solve the above problems (detailed three-dimensional, print depth, productivity, cost, workability, surface durability) in configuring the surface layer 10 of the long vinyl flooring, the specific pattern of the print layer 11 and As the concave-convex embossing roll, the transparent sheet layer 12 is placed on the upper part of the printed layer, and the specific pattern of the printed layer and the concave-convex pattern of the embossing roll are matched (hereinafter, the long-tuned embossing method). By imposing pearl ink on the swelling area of the swelling area, the embossed pattern is transferred and the pearl ink is directly transferred (hereinafter valley printing method) to provide a sense of depth due to the double printing effect, the softness of pearl, and the embossed pattern that matches the printed pattern. The problem is solved by expressing a three-dimensional appearance that can feel a three-dimensional feeling, realism, and luxury.

In long vinyl flooring, the printed pattern and the uneven pattern of the embossing roll are matched, that is, during the tuning embossing, the printed pattern of the printed layer is deformed by the heat involved to give the embossed pattern and the tension for the progress of the fabric. In order to solve the pattern and the embossing pattern was impossible, the present invention primarily uses a glass fiber sheet layer of the dimensional reinforcement to minimize the printed pattern deformation, and also suitable heat conditions supplied to the tuning embossing roll at a constant speed Set the range (140 ~ 180 ℃) and tension (30 ~ 120Kgf / ㎠) and match the printed pattern and embossed pattern while driving the embossing roll at the same speed, faster or slower than the working speed. By imposing pearl ink on the surface and transferring the ink directly with embossing, the depth and realism of printing, the softness of pearl, the fineness of embossing, and the three-dimensional The aims to provide long flooring can feel.
