[Industrial use]

The present invention relates to a floor covering and a method of manufacturing the same. In particular, the present invention relates to a melamine sheet-laminated vinyl chloride floor decoration material in which a melamine sheet having excellent surface properties is laminated on a vinyl chloride sheet, and a method of manufacturing the same.

[Prior art]

1 is a cross-sectional view of a conventional vinyl chloride resin floor decorative material, which has a substrate layer (1) that adds thickness and balances to a product, and has a printing layer (2) having a beautiful pattern on the substrate layer (1). ), The transparent layer 3 which protects the pattern of the printed layer 2 and the surface coating layer 4 which impart stain resistance and scratch resistance to the product are laminated in this order, and also under the base layer 1 is balanced. The bottom decoration material to which the balance layer 5 was attached is shown. At this time, in the case where the balance of the floor decoration material is satisfied only by the base material layer 1, the balance layer 5 may be omitted.

The manufacturing method of such a conventional floor covering is as follows.

First, the base material layer 1 is manufactured.

The base material layer 1 is produced by rolling a soft or hard vinyl chloride resin compound with a calender to a thickness of 2-3 mm.

Next, a printed layer 2 and a transparent layer to be laminated on the base layer 1 and a balance layer 5 to be attached below the base layer 1 are prepared.

The printing layer (2) is directly gravure printing on a vinyl chloride resin sheet prepared by rolling a soft or hard vinyl chloride resin compound containing 10 to 20% by weight of a good hiding power with a calender to a thickness of 0.08 to 0.15 mm. Or by printing and drying a variety of patterns such as natural stone pattern or wood pattern using a method such as transfer printing.

In addition, the transparent layer 3 is made of a transparent vinyl chloride resin film having a thickness of 0.10 to 0.90 mm by rolling a soft or hard vinyl chloride resin compound with a calender.

In addition, the balance layer 5 is produced by rolling a soft or hard vinyl chloride resin compound with a calender to a thickness of 0.32 to 0.95 mm.

Next, the printed layer 2 and the transparent layer 3 prepared above are laminated on the base layer 1 in turn, and the balance layer 5 is placed below the base layer 1, and then heated and pressed by a press to print. The layer 2, the transparent layer 3, and the balance layer 5 are laminated to the base layer 1.

Next, a surface coating agent containing urethane acrylate resin as a main material is coated on the transparent layer 3 to a thickness of 5 to 60 μm and cured with ultraviolet rays, or a surface coating agent containing urethane resin or acrylic resin as the main material is transparent layer 3 By coating on the surface and curing with heat or ultraviolet rays to form a surface coating layer (4) to prepare a floor decorative material of 2.5 to 5.0 mm thick.

Conventional flooring material manufactured by the above method has been used steadily because of the low cost, convenient construction, but the top layer surface coating layer lacks stain resistance and scratch resistance applied to the flooring material to wear shoes or pass through There was a problem that the contamination is good in the frequent place or the scratches on the surface well, which is reducing the amount of use in department stores or boulevards.

In order to solve this problem, recently, a floor decorative material having a melamine resin impregnated layer having a high hardness surface property as a top layer has been introduced, which is illustrated in FIGS. 2 to 4, and these conventional techniques are as follows. .

2 is a cross-sectional view of a decorative laminate board of European Patent Application Publication No. 0 561 086 A1, on which a phenolic resin adhesive layer 12, a melamine resin impregnating layer 13 and a melamine resin are impregnated on a vinyl chloride resin layer 11; The overlay plates 14 are sequentially stacked.

FIG. 3 is a cross-sectional view of a melamine sheet laminated vinyl chloride floor decorative material filed by the applicant in 1997 Patent Application No. 51149, and includes a vinyl chloride sheet layer 21 and a modified phenolic resin on the vinyl chloride sheet layer 21. The adhesive layer 22 made of a sheet impregnated with paper, the core layer 23 made of a sheet impregnated with a phenolic resin, a shape layer 24 made of a sheet impregnated with a melamine resin, and a sheet of melamine resin The transparent protective layer 25 of the sheet impregnated in the above is laminated in this order, and a sheet or a vinyl chloride resin impregnated with a melamine resin, a phenol resin, a phenol-modified resin or an acrylic resin in the paper is impregnated under the vinyl chloride sheet layer 21. It is a floor decoration material to which the balance layer 26 of the made glass fiber, nonwoven fabric, or soft vinyl chloride sheet was attached.

4 is a cross-sectional view of the laminate of Japanese Patent Application Laid-Open No. 9-123366, wherein the hot melt film 32, the pattern paper 33, and the melamine resin impregnated overlay 34 on the rubber or thermoplastic resin 31 are shown. Is a laminated body laminated one by one.

As described above, the bottom decorative material using the conventional melamine resin impregnated layer shown in FIGS. 2 to 4 is the uppermost layer, the melamine resin impregnated overlay 14, the transparent protective layer 25 made of a sheet impregnated with the melamine resin, and the melamine resin. Melamine resin impregnation layer such as the impregnation overlay 34 is used to solve the problem of scratching and surface contamination of the surface of the floor decoration material, but the melamine resin impregnation layer and the vinyl chloride number below The following problems are encountered in the adhesive layer and other parts used for bonding the layer.

The decorative plate of FIG. 2 is incompatible with the vinyl chloride resin of the vinyl chloride resin layer 11, the phenol resin of the adhesive layer of the phenol resin adhesive layer 12, which is an adhesive layer, and thus has poor adhesiveness, and is easily broken by external impact. Since there is no hard sheet that complements the melamine resin having properties, there is a problem such that the center portion of the decorative plate is turned down when lifted up while holding the edge of the decorative plate.

The floor decoration material of FIG. 3 solves a problem due to the phenol resin which is incompatible with the vinyl chloride resin by using an adhesive layer 22 made of a sheet impregnated with a modified phenolic resin, etc., instead of a phenolic resin. When used, there is a problem in that the adhesive force of the adhesive layer 22 is lowered or lost according to environmental changes.

In addition, in the laminate of FIG. 4, the hot melt film 32 used as the adhesive layer between the rubber or thermoplastic resin 31 and the pattern paper 33 has increased crystallinity at the bonding temperature, thereby reducing the size of the hot melt film 32 itself. There was a problem in dimensional stability, and also there is a problem in maintaining the balance of the laminate according to the temperature and humidity changes.

In addition, the conventional floor coverings shown in Figs. 1 to 4 commonly have large curling and warping. Many such curvatures (curling or warping) occur especially at temperatures below -10 ° C and above 40 ° C. The reason is that the four seasons, like ours, are macroscopically affected by the environment, and microscopically, the matrix itself is weak to thermal changes due to different shrinkage and expansion with respect to temperature and humidity of the various layers. To compensate for this, it is necessary to complement the matrix configuration.

In view of the problems of the prior arts described above, the present invention uses a resin impregnated layer impregnated with a melamine resin as a surface layer, thereby greatly improving scratch resistance and stain resistance of a floor decoration material, thereby increasing the vinyl chloride resin floor having high strength surface properties. In the decoration material and its manufacturing method, in order to solve the above problems of the conventional floor decoration material using an adhesive layer between the resin impregnation layer and the vinyl chloride resin layer thereunder, a balance layer between the resin impregnation layer and the vinyl chloride resin layer beneath it. Pressing, heating and compressing with a press to allow the fibers in the balance layer to penetrate simultaneously into the resin impregnating layer and the vinyl chloride resin layer, which are the upper and lower layers of the balance layer, and thus the adhesion between the resin impregnating layer and the vinyl chloride resin layer having poor mutual adhesion And the fibers in the balance layer and the balance layer reinforce the entire matrix Vinyl chloride resin, which greatly reduces the warpage at the time of the ball before and after the curl phenomenon and carry flooring, and intended to provide a method of manufacturing the same.
